Cross-cultural analysis of the ecological behavior of Chilean and Spanish ecotourists: a structural model

1University of Castilla-La Mancha, Spain, 2University of Murcia, Spain

ABSTRACT

Citizen concern for the environment in light of problems such as freshwater shortages, deforestation, and climate change has been steadily increasing in postmodern societies since the mid-20th century. Ecotourists and their proenvironmental or proecological behavior are still areas of opportunity for research in order to understand the factors, whether economic, cultural, social, demographic, or psychographic, that determine this behavior. This research uses the value-belief-norm (VBN) theory and the theory of planned behavior (TPB) to analyze the intention to practice ecotourism among ecotourists from two countries with different cultures and customs. Based on these premises, the objective of this work is to create a new model that facilitates the understanding of the intention to practice ecotourism, as well as the intention to pay more for it, by comparing ecotourists from two different cultures, Chilean and Spanish, in which the importance of ecotourism is similar. The data were obtained from a panel of 809 ecotourists (406 Chileans and 403 Spaniards) through partial least squares-structural equation modeling. The results indicate that the model is a good fit to the data; therefore, the hypotheses were confirmed. Specifically, the construct of conscience in consequences and the construct of personal norms have a strong influence on the intention to practice ecotourism. The results suggest that the proposed model is a useful framework for understanding the behavioral intention of ecotourists from different countries and their intention to pay more for ecotourism. The cultural differences between the two countries did not affect the causal relations established in the model in any way.

INTRODUCTION

The interest in research on the ecological behavior of society in general and of individuals in particular has led scholars in different disciplines, including social psychology, sociology, and marketing, to produce many studies, some focusing on socio-demographic aspects and others focusing on aspects of social psychology (Liu et al. 2018). Concern for the environment among tourists in recent decades has led to the explosion of so-called sustainable tourism and ecotourism, which attempts to reconcile environmental values and tourism development (Dias 2007, Puhakka and Siikamäki 2012, Hwang and Lee 2018). According to Epler Wood (2002), ecotourism is an alternative tourism that practices nature tourism by helping to conserve the environment in which the tourist is received for the benefit of both visitors and the local destination community. Different authors have found that ecological behavior and the internal or external factors such as culture that determine such behavior can lead to new forms of tourism, such as ecotourism or nature tourism (Hultman et al. 2015, Hwang and Lee 2018).

To manage ecological behavior and understand the feedback between ecosystems and humans, Martone et al. (2017) develop a qualitative model to analyze complex social-ecological systems (SES), focusing on the observation of behavioral results in relation to external perturbation of ecosystems. Their model is congruent with the value-belief-norm (VBN) model (Stern et al. 1999), in which basic human values (Schwartz and Bilsky 1987), personal normative influence (PNI; Schwartz 1977), and the new environmental paradigm (NEP; Van Liere and Dunlap 1978) are analyzed to test the basic human values that guide the generation of attitudes in different international contexts. These social-ecological behaviors differ depending on the ecosystems analyzed and are associated with different external and internal perturbations, such as culture, economic situation, and motivation. In sum, integrating ecological and psychological-social variables into a unique unit of management reveals relevant potential trade-offs between desirable ecological and social outcomes. In this sense, it is important to note the user groups that might be vulnerable to external perturbations and identify the specific interventions that should be further tested to identify potential beneficial outcomes across the sustainable development paradigm (Martone et al. 2017). In this way, interest in conserving the natural environment can encourage consumers to consider the environment in their day-to-day activities (Untaru et al. 2014). This consideration translates into a growing preference for purchasing products that are less harmful to the natural environment (Laroche et al. 2001), thus reducing waste, using nontoxic substances, modifying consumption patterns, and conserving energy (do Paço et al. 2014, Chen 2015). In the tourism sector, the profile of tourists has changed, and they increasingly demand activities that do not harm the environment (Pulido-Fernández and López-Sánchez 2016). A consumer reaction against traditional or mass tourism, which denotes consumer habits and demand for sophisticated services based on activities such as visits to beaches, historic cities, or cultural attractions, has given rise to so-called alternative tourism. This type of tourism has emerged in the 21st century as tourists have participated in activities that bring them into contact with nature; respect heritage, especially historical heritage; and enable them to interact with the local population. This emphasis has led to the emergence of different forms of tourism, such as cultural tourism, rural tourism, agrotourism, ecotourism, adventure tourism, and hunting (Ibáñez and Rodríguez 2012).

Concern for the environment has also changed the tourism industry and caused an upsurge in what have been termed sustainable tourism and ecotourism, which seek to combine environmental values and the development of tourism (Puhakka and Siikamäki 2012). This type of tourism is currently growing three times more rapidly than conventional tourism and aspires to a more prominent place in the global tourism market (Das and Chatterjee 2015).

The Sectoral Plan for Nature and Biodiversity Tourism 2014–2020 (https://www.miteco.gob.es/ca/biodiversidad/temas/conservacion-de-la-biodiversidad/conservacion-de-la-biodiversidad-en-espana/cb_esp_plan_sect_turismo_nza_y_biodiversidad.aspx) proposes a model to follow in nature tourism and biodiversity: “A model that contributes to the value of natural wealth for ecotourism, that promotes balanced socio-economic development and drives the generation of income and employment, without undermining biodiversity and improving its management and conservation.” Actions include promoting the configuration of sustainable destinations and tourism products and improving the consideration of biodiversity, as well as knowledge of it, in ecotourism activities. According to data from the World Tourism Organization (2019), ecotourism has grown significantly in recent decades, accounting for 15% of total world tourism. It is a growing activity in Spain (MAPAM 2017) and Chile (Senatur 2017). In sum, ecotourism is an economic resource for the development of local populations near the observed destinations and promotes knowledge of the natural environment and the species that inhabit it. Therefore, nature tourism has become an integrative tool for improving the economy of rural areas and bringing visitors closer to the work of protecting and conserving natural resources.

Research on consumer behavior aims to understand the attitudes of ecotourists (Han 2015, Hultman et al. 2015, Han et al. 2017, Kiatkawsin and Han 2017, Hwang and Lee 2018), characterizing ecotourism as “a particular type of alternative tourism closely associated with environmentally and culturally sensitive areas” (Lu et al. 2016:176). However, the ecological behavior of these consumers is a field of research that still has unexplored areas, especially regarding a better understanding of the importance of psychographic, personality, cultural, economic, and demographic factors (Weaver and Lawton 2002, do Paço and Raposo 2009, Han 2015, Hultman et al. 2015, Kiatkawsin and Han 2017). Typically, research on ecological behavior is carried out through the study of different forms of behavior, whether in the private sphere or the public sphere, e.g., social and political participation, energy saving, etc. (Stern 2000, Steg et al. 2005, Yeboah and Kaplowitz 2016). In the field of tourism, it is common to study behaviors such as visiting ecological hotels or natural parks (van Riper and Kyle 2014, López-Mosquera and Sánchez 2011). Similarly, some investigations are linked to behavior intention, which, according to Ajzen (1991), is the closest antecedent to the realization of a behavior, such as the intention to visit ecological museums (Han and Hyun 2017), the intention to visit an ecological hotel (Choi et al. 2015, Han 2015) or the intention to behave in an ecological way while traveling (Kiatkawsin and Han 2017, Landon et al. 2018).

Research on ecotourist behavior is based on the analysis of either consumption intention or consumption itself (Han 2015, Kiatkawsin and Han 2017). Our approach follows the theory of planned behavior (TPB; Ajzen 1991), which points out that the antecedent closest to a particular behavior indicates the individual’s willingness to perform that behavior (de Groot and Steg 2008). In addition, the VBN model (Stern et al. 1999) has been shown to be a powerful framework for explaining different ecological behaviors (Stern 2000), such as citizens’ movements, political actions, and political support (Yeboah and Kaplowitz 2016), and for understanding proecological behavior in the field of tourism (Han 2015, Choi et al. 2015, Han and Hyun 2017). We choose to study the intention to practice ecotourism and the intention to paying more for it.

This study primarily addresses the behavior of the ecological consumer; although studies in this area exist, the results to date have not been conclusive (Miguens et al. 2015). For Manrai and Manrai (2011), culture influences tourist behavior, whether the motivation for the trip, the decision making, or the behavior behind the decision making. However, this subject has been little studied in the literature (Meng 2010, Hwang and Lee 2018). In addition, after reviewing the diverse literature, we did not find cross-cultural studies that examine the constructs of Stern’s model (2000). The absence of such studies is probably due to the lack of employability of the theory of reasoned action or planned behavior, which is generally used in studies investigating the moderating and mediating effects of culture (Baron and Kenny 1986).

On the other hand, different studies have indicated that conceptual models that combine theories based on prosocial motivations and individual motives better explain the variance of behaviors or intentions of proenvironmental behaviors (Bamberg et al. 2007, Bamberg and Möser 2007). For example, there is utility in combining the VBN theory (Stern 2000) and the TPB in a conceptual model.

Research on the ecological behavior of consumers, and specifically in the field of tourism, is scarce in terms of knowledge of the importance of psychosocial factors, attitudes, or sociocultural factors (Weaver and Lawton 2007, do Paço and Raposo 2009, Han 2015, Hultman et al. 2015, Kvasova 2015, Kiatkawsin and Han 2017).

Furthermore, the literature review emphasizes the need to deepen the understanding of environmentally responsible behavior by incorporating the external, contextual, or group variables that influence such behavior (Miguens et al. 2015). In addition, scant research exists on the relationship between personality traits and the environmentally responsible behavior of individuals in the tourism industry (Kvasova 2015). It is important to remember that ecotourists are a type of consumer with their own characteristics; they are interested in environmental conservation and the cultural preservation of the places they visit as well as experiencing and learning new things from the natural environment (Juric et al. 2002). Therefore, it is interesting to apply the VBN model to the environmental context (Stern et al. 1999). In addition, as Chen (2015) indicated, social values and norms are essential in the understanding of so-called ecological behaviors, which is why we use the VBN model (Stern et al. 1995, 1999, Stern 2000). In the field of tourism (Han 2015, Hultman et al. 2015, Kvasova 2015, Kiatkawsin and Han 2017), where environmental values, attitudes, beliefs, and norms are interrelated, this model is of great interest, particularly if we combine it with the TPB (Ajzen 1991) to improve the explanatory capacity of the proposed model (Bamberg et al. 2007, Bamberg and Möser 2007). The VBN model is based on the confluence of the theory of values (Schwartz and Bilsky 1987), the model of normative influence (NAM; Schwartz 1977), and the new ecological paradigm (NEP; Van Liere and Dunlap 1978). The first theory adopts the traditional conception of values as principles that guide the development of attitudes, the explanation from the NAM model of the mechanism that drives individuals to adopt altruistic behaviors, and the concept of social conscience about the effects of human actions on the biosphere or an environmental vision of the world from the NEP. In sum, it is a model in which personal norms are activated in the consciousness of the consequences of unsustainable behaviors on the environment through people’s beliefs in accepting responsibility for the impact of their behavior on the environment.

This research differs from existing studies in some interesting ways. First, we wanted to create a comprehensive model that combines several models, an unusual approach to studying ecological behavior in tourism services (Han 2015). Therefore, we proposed a comprehensive application of the VBN model (Stern et al. 1999) to the tourism sector, which is an innovative contribution to this field of research because previous studies have used only portions of this model to explain consumer ecological behaviors (Choi et al. 2015). Additionally, following the example of Choi et al. (2015), we incorporated the construct of personal norms from the TPB to determine how the intention to undertake ecotourism and the intention to pay more for ecotourism relate to the VBN model. Thus, we created a broader model capable of collecting more variables that, according to our hypotheses, may influence ecotourists’ behavior. Finally, we incorporated socio-demographic factors into the research because these factors have been considered unimportant in the models of various previous investigations and in many cases have been underestimated by researchers (do Paço and Raposo 2009).

Regarding methodology, we conducted a cross-cultural study of the ecological behavior factors of ecotourists in two countries (Spain and Chile) given the importance of ecotourism in these regions. Nel-lo and Llanes (2016) point out that ecotourism represents 10% of worldwide tourism. Moreover, for the countries chosen for our research, we found the following relevant data: 2.7 million visits to nature parks in Chile and more than 14 million visits to Spain (SENATUR 2015). Chile is especially interesting given its effort in 2017 to create new nature parks, resulting in the protection of 20% of its total national territory (Cué 2017). Spain has protected 13% of its natural areas, and more than 27% of these areas are included in the Natura Network. In Spain, nature tourism accounts for between 12% and 29% of tourist activity (MAPAM 2017). Regarding the importance of ecological tourism, we must point out that 70% of Chile attracts nature tourism (Notiamérica 2015); specifically, Chilean natural areas received 3,019,432 visits, of which 71.4% were national and the rest foreign (Senatur 2017).

To understand the differences between the two countries, we used the cultural dimensions developed by G. Hofstede (Hofstede Insights 2018). We adopted this approach because cultural values influence every aspect of human life: personality, lifestyle, psychology, and motivation (Manrai and Manrai 2011). Hofstede’s dimensions facilitate analysis on a national level and are standardized to allow multiple and easier comparisons between countries.

According to Hofstede (Hofstede Insights 2018), the cultural dimensions and their values for Spain and Chile are as follows:

  1. Power distance index (PDI): reflects the perception that members of society have an unequal distribution of power and the extent to which this inequality is accepted in a society. The PDI for Chile (63) is higher than that for Spain (57).
  2. Individualism (IDV): level at which the individuals of a country tend to see themselves as self-sufficient individuals (individualists) compared to a tendency to see themselves, above all, as part of a social group (collectivists). The IDV in Spain (51) is higher than that in Chile (23), indicating that Spanish society has more individualist attitudes and fewer ties with others.
  3. Masculinity (MAS): level at which values such as assertiveness, performance, success, and competitiveness prevail in a culture over values such as kindness, quality of life, maintaining warm personal relationships, service, and caring for the weak. The MAS score for Chile is very low (28) compared to that for Spain (42), which indicates that Chile has a more feminine culture.
  4. Uncertainty avoidance index (UAI): level at which individuals in a given culture feel uncomfortable with uncertainty and ambiguity. For this variable, Chile and Spain have the same score (86).

Therefore, because of the lack of research in this area, the aim of this study was to apply a cross-cultural perspective to determine the internal and external factors that influence the behaviors of consumers identified as ecotourists (tourists who engaged in ecological consumption in the previous year), behaviors that lead them to take environmentally responsible trips that conserve the environment and support the well-being of the local community, as well as the factors that shape their purchasing intentions. In sum, we developed a comprehensive model to holistically explain the variables that act on ecological behavior or that affect the intentions of both undertaking and paying more for ecotourism, thus enabling a better understanding of the characteristics of ecotourists on which the thriving ecotourism market depends.

METHODS

To conduct this study, we began with several previous studies that reveal the importance of the ecological behavior of tourists. These studies address tourists’ values (Han 2015, Kiatkawsin and Han 2017), environmental beliefs (van Riper and Kyle 2014), awareness of consequences (Han 2015, Kiatkawsin and Han 2017), assignment of responsibility (Kiatkawsin and Han 2017), personal norms (Choi et al. 2015), subjective norms (Lu et al. 2016), ecotourism intentions (Laroche et al. 2001, Hultman et al. 2015, Lu et al. 2016), and intention to pay more (for ecotourism; Laroche et al. 2001, Hultman et al. 2015, Lu et al. 2016).

Developed by Stern et al. (1999), the VBN model is a comprehensive model that uses a psychological approach. The VBN is a hierarchical model that derives its robustness from a successive chain of elements that, when faced with an ecological or environmental problem, directly or indirectly activate the next element.

The VBN theory is based on three preceding theories: Schwartz’s theory of basic human values (Schwartz and Bilsky 1987), the PNI model (Schwartz 1977), and the NEP (Van Liere and Dunlap 1978). From the theory of basic human values, the VBN theory adopts the traditional conception of values-principles that guide the development of attitudes. In addition, the VBN theory draws on the PNI model for an explanation of the mechanism that drives individuals to adopt altruistic behavior. Last, from the NEP, the VBN theory derives the notion of social awareness regarding the effects of human activity on the biosphere, an environmental perspective of the world. The VBN model has been used in tourism to examine consumption in ecofriendly hotels (Choi et al. 2015, Han 2015), the environmental behavior of young travelers (Kiatkawsin and Han 2017), and recreational behavior (Lee and Jan 2018). Table 1 presents the different constructs analyzed in this study as well as the items used to measure each variable.

We applied a questionnaire as an instrument to collect data from the sample units in Chile and Spain. The questionnaire consisted of more than 80 closed-ended, dichotomous (or multichotomous/polytomous), and multiple-choice questions as well as one open-ended question. The purpose of the questionnaire was to obtain information about the trips taken by the respondents and about their values, beliefs, subjective and personal norms, behavioral intention, and willingness to pay a potential premium. The closed-ended questions were scored on a five-point Likert scale ranging from 1 “completely disagree” to 5 “completely agree,” and the open question requested the respondent’s age. The questionnaire was distributed and completed online through a market research company.

The final sample consisted of 406 Chilean and 403 Spanish tourists; thus, the margin of error is lower than 5% for a confidence level of 95%. The percentages in the sample were very similar to those in the overall tourist population (SENATUR 2013, INE 2016). We selected Chile and Spain given the significance of nature-based tourism for their economies: 2.7 million visits to Chile and more than 14.4 million visits to nature parks in Spain (SENATUR 2015, EUROPARC 2016).

The main objective of this study is to analyze the relationships between the latent variables of Chile and Spain to understand the keys to people’s intentions to undertake ecotourism and, consequently, to pay more to do so. Therefore, the base model selected to test our hypotheses is the VBN (Stern et al. 1999), as previously explained.

Most of the research carried out with the VBN model has opted to work with biospheric values. These values are guiding principles of people’s lives that represent concern for nonhuman species and the biosphere as a whole (Aguilar 2006). Research has shown that they influence attitudes toward the environment in terms of behaviors (Dietz et al. 1998, Han 2015, Kiatkawsin and Han 2017) and that these values are maintained (de Groot and Steg 2008) in both daily life and behavior related to tourism (Lee and Jan 2018). Meanwhile, van Riper and Kyle (2014) point out that selfish values have a negative effect on personal norms, and biospheric and altruistic values have a positive influence on personal norms.

As mentioned above, biospheric values, according to Aguilar (2006), are guiding principles of people’s lives that represent concern for nonhuman species and for the biosphere as a whole. Social/altruistic values, according to Aguilar (2006), are guiding principles of people’s lives that represent concern for the well-being of others. These values are manifested through social justice, utility, equality, and a peaceful world. Egocentric/egoist values, according to Aguilar (2006), are those that represent concern for oneself. The items or variables that help us identify egocentric values are authority, wealth, social power, and influence. Thus, Stern (2000) points out that environmental concern is promoted by collective or altruistic values, that biospheric values refer to the biosphere and other species, and that selfish values refer to an individual’s own interest. Van Riper and Kyle point out that biospheric and altruistic values are expected to be positive in their influence on the environmentalism of individuals and that selfish values are expected to have a converse influence; these values also affect the moral obligation that precedes proenvironmental behavior (Stern et al. 1995).

In sum, taking into account the difference between the probiosphere and other-species view of biospheric values and the anthropocentric and self-interested view of selfish values (Stern 1999), there are differences in the effects of these values on environmental attitudes. Selfish values have a negative effect on environmental beliefs in comparison to biospheric and altruistic values, which favor proenvironmental attitudes (van Riper and Kyle 2014, Choi et al. 2015).

As explained previously, according to Stern (2000), values are the first element to influence consumer behavior and to activate beliefs. The NEP is one of the belief constructs in the VBN model. Based on Dunlap et al. (2000:427), the NEP refers to “beliefs about humanity’s ability to alter the balance of nature and the existence of limits to growth for human societies.” Dunlap and Van Liere (1978) created a 4-point Likert scale with 12 items chosen from a total of 35 in their 1976 study of the ideas of Washington State residents on the environment, pollution, population, and natural resources; nine items were related to the NEP and the rest to the dominant social paradigm (DSP). The scale has different dimensions or ideas: the limits of growth, the natural balance, and the anthropocentric vision of the environment. In 2000, Dunlap et al. (2000) carried out a review of the NEP with some improvements, including “taking advantage of a wider range of facets of an ecological worldview; offering a balanced set of pro and anti-NEP articles; and updating terms” (p.425).

Environmental problems stem from the values, attitudes, and beliefs of societies, such as individualism, progress or abundance, free enterprise or respect for quality of life. From this perspective, the DSP encompasses the vision of the world or way of interpreting it. This paradigm must be overcome by a more realistic vision of the world in the face of ecological problems and the inevitable limits to growth in favor of balance with nature and the rejection of the anthropocentric view; this new vision of the world is the NEP (Dunlap and Van Liere 1978). Dunlap et al. (2000) modified the NEP to 15 items scored on a 5-point Likert-type scale, updated the terms and made them gender neutral. The new NEP included three additional items in five dimensions with two new items: the rejection of the concept of humans as the most exceptional species and the belief in ecological crises. The items were distributed in two parts, with seven items related to the NEP and six to the DSP; four of the original items were modified, and six were maintained.

Ecologically responsible behavior can be considered altruistic behavior and depends on the activation of personal norms, which, in turn, are a function of an individual’s values. The activation of personal rules by values is explained by two other variables.

The first variable is the assignment of responsibility, understood as the degree to which an individual feels responsible for the impact of his or her conduct on the environment (Schwartz 1977). The second variable is awareness of the consequences of the action or, in other words, the specific beliefs associated with the behavior. It comes from Schwartz’s (1992) model, which points out that knowledge of the consequences refers to the fact that individuals tend to realize the consequences of their behaviors for others. Personal norms are, according to Schwartz and Howard (1981:191), the “moral obligation to take or refrain from specific actions.” Personal norms are key among the elements within the VBN model for the predisposition to become a behavior (Stern 2000).

Choi et al. (2015) point out that a person with strong personal norms has greater intentions to visit an ecological hotel than a person without them. Personal norms are also important for consumption-restricting behaviors (Jansson et al. 2010).

H1. Biospheric values positively influence the new ecological paradigm.

H2. Selfish values negatively influence the new ecological paradigm.

H3. The new ecological paradigm positively influences the awareness of consequences.

Regarding the awareness of consequences, several studies have pointed out its relationship with the assignment of responsibility in the field of ecological consumption and tourism (Stern et al. 1995, Ibtissem 2010, van Riper and Kyle 2014, Choi et al. 2015, Kiatkawsin and Han 2017), and others have demonstrated its relationship to personal norms and behavioral intentions (Wynveen et al. 2015).

H4. Awareness of consequences positively influences the assignment of responsibility.

H5. Awareness of consequences positively influences personal norms.

H6. Awareness of consequences positively influences intentions to undertake ecotourism.

Similarly, the relationship of the influence between the assignment of responsibility and personal norms has been widely acknowledged in the literature that applies the VBN model (Stern et al. 1999, de Groot and Steg 2008, Ibtissem 2010, van Riper and Kyle 2014, Choi et al. 2015, Kiatkawsin and Han 2017).

H7. The assignment of responsibility positively influences the personal norms of tourists.

Several studies have noted the positive relationship between the proenvironmental personal norms of tourists and their intentions to behave in an ecofriendly way when traveling (Kiatkawsin and Han 2017) or to stay in ecofriendly hotels (Choi et al. 2015, Han 2015) as well as their intentions to pay more for an ecological activity or cruise (Han 2015).

H8. Personal norms positively influence intentions to undertake ecotourism.

H9. Personal norms positively influence intentions to pay more to undertake ecotourism.

Han et al. (2017) study the positive influence of subjective norms on the intention to revisit ecofriendly hotels; other studies examine behaving appropriately in an ecological museum (Han and Hyun 2017) and undertaking ecotourism activities on a trip (Lee and Jan 2018). Additionally, Han (2015) offers a comprehensive view of the formation of proenvironmental intentions by travelers staying in ecofriendly lodgings. This author notes that subjective norms influence the personal norms (sense of duty) of the VBN model as well as behavioral intentions.

H10. Subjective norms positively influence personal norms.

H11. Subjective norms positively influence intentions to undertake ecotourism.

Regarding the intentions of ecotourists to pay more, we note that a study by Hultman et al. (2015) on the intentions to pay higher prices for visiting ecotourism sites applies postmaterialist theory and the TPB. A study by López-Mosquera (2016) is in a similar vein, although it is related to higher prices paid for visiting a nature park.

H12. The intention to undertake ecotourism positively influences the intention to pay more to undertake ecotourism.

The proposed model was evaluated using partial least squares structural equation modeling (PLS-SEM). The most important reason to select PLS-SEM instead of covariance-based SEM (CB-SEM) is the research goal. The primary purpose of the PLS approach is to predict the indicators by means of the component’s expansion (Jöreskog and Wold 1982). This method is accepted as a key multivariate statistical technique to estimate cause-effect relationships between constructs in international marketing research and across different groups of respondents. Additionally, the PLS algorithm is well suited to our case because it imposes fewer restrictions on data normality and because a predictive model is used (Anderson and Gerbing 1988, Cepeda and Roldán 2004, Sarstedt et al. 2014). We conducted the analysis in two stages. First, we developed a general model, and second, we applied the model to the two categories of Chile and Spain. In sum, Table 2 shows all hypotheses included in the causal model.

RESULTS

To perform the data analysis, we applied a model based on the PLS-SEM method (Hair et al. 2014, Sarstedt et al. 2014) using Smart PLS 3.0 software (Ringle et al. 2017). To determine the stability of the estimates, we tested the data using 2500 subsamples. Next, we analyzed the reliability and validity of the proposed general model and then evaluated it (Anderson and Gerbing 1988).

To determine the suitability of the proposed model, this study met the criteria for internal reliability and validity, content validity, and convergent and discriminant validity. As shown in Table 3, the values for Cronbach’s alpha confirm the reliability of the scales. These values range from a maximum of 0.948 to a minimum of 0.694 and are therefore higher than or approximately equal to the recommended values for scale robustness (Nunnally 1978). The composite reliability of the model fluctuates between 0.823 and 0.957, thus exceeding the 0.7 threshold indicated by Nunnally (1978). In addition, the average variance extracted (AVE) of each construct was analyzed, revealing values greater than the suggested 0.5 (Fornell and Larcker 1981) except for the NEP construct (0.404). This result indicates that this construct is difficult to explain using its constituent variables.

Convergent validity is verified by analyzing the factor loadings and their significance. The individual item loadings in our model are higher than 0.6 (Bagozzi and Youjae 1988). Additionally, we checked the significance of the loadings with a resampling procedure (500 subsamples) to obtain t-statistic values, which were all significant (p < 0.001). This finding supports the convergent validity of the indicators (Hair et al. 2014).

Discriminant validity indicates the extent to which a given construct is different from other latent variables. This research adopted the Fornell and Larcker (1981) criteria of discriminant validity to examine whether the square root of the AVE for each construct exceeded the correlation of the construct and other constructs in the model. As shown in Table 4, all diagonal values exceeded the interconstruct correlations, thereby demonstrating adequate discriminant validity of all constructs.

To evaluate the predictive capacity of the structural model, we analyzed the independent variables through the variance of the endogenous variables that are able to explain the constructs that predict them (Cepeda and Roldán, 2004). Regarding the optimal values of this predictive level, we applied the Falk and Miller (1992) method, which requires the R² value of the constructs to be greater than 0.1. Our results show that all values are greater than 0.1. Therefore, the most significant variables included in the model were able to explain 0.363 of the variance in the intention to pay more for ecotourism (Table 5).

Regarding the global adjustment indicators, we applied a goodness-of-fit (GoF) index. The values of the GoF index varied between 0 and 1; it is usually recommended that they be higher than 0.31 (Chin 1998) to indicate acceptable model fit. The result for our general model fit was 0.459.

Regarding our hypotheses, we note that all hypotheses were confirmed (Table 5) at 10% and that 11 hypotheses were confirmed at 5%; the exception was hypothesis 6, which measures the relationship between awareness of consequences and the intention to undertake ecotourism.

We observed some differences in the proposed general model between Chile and Spain, which could be caused by cultural differences. We incorporated the moderating effect of culture into the model and aligned it with our proposed methodology using the multigroup PLS technique.

Table 5 presents the results of the multigroup analysis. We did not observe significant differences in any of the 12 hypotheses at p < 0.01 or even at p < 0.05. These results indicate that there is no moderating effect of culture or country of residence in the way that we stated the hypotheses. This finding may signify either the robustness of the model or that, despite the different results for the cultural dimensions, the cultures are not sufficiently different. Figure 1 illustrates the hypothesis test for the global model.

DISCUSSION AND CONCLUSIONS

Managing for sustainable development and resource extraction requires an understanding of the feedback between biophysical systems and humans and thus requires an integrative, interdisciplinary approach. Such feedback is part of SES in which resources, actors, and governance systems interact to produce outcomes across the component parts (Cox et al. 2010, McGinnis and Ostrom 2014). Within the tourism framework, the growth of ecotourism as a form of alternative tourism has prompted the tourism industry to become increasingly interested in understanding the factors that affect, influence, or moderate the behavior of people who undertake ecotourism. The purpose of this research study was to examine the ecological behavior of the ecotourist.

Our study is based on the VBN model (Stern et al. 1999) complemented by a TPB construct (Choi et al. 2015), personal norms, to explain the behavioral intentions of ecotourists as consumers of products or services from a cross-cultural perspective (two countries, Chile and Spain) as well as their intention to pay more for ecotourism. The results confirm the robustness of the model because there are no significant differences between the countries, which indicates that ecotourism behavior is similar regardless of the country of origin.

We demonstrated that values directly influence environmental beliefs. Biospheric values, which guide life principles that represent concern for nonhuman species and the biosphere as a whole, have a positive influence, and selfish values, which represent concern for oneself, have a negative influence. Therefore, the biospheric orientation is related to the intention for ecological behavior, as opposed to selfish behavior (Stern et al. 1995). In sum, regarding environmental values and beliefs, the model indicates the existence of a significant relationship between biospheric values, similar to the findings of other studies (Stern et al. 1995, 1999, Ibtissem 2010, Choi et al. 2015). In contrast to studies such as Lee and Jan (2018), it also usefully considers selfish values, such as differences in the use of selfish values. However, the proposed model does not use indicators for social/altruistic values, which differentiates it from previous studies indicated (Stern et al. 1995). Therefore, the idea of the “benefits and costs for others” is not incorporated into the model, in contrast to studies such as Ibtissem (2010), van Riper and Kyle (2014), and Han et al. (2017).

The NEP is a highly laborious construct. Despite the fact that the questionnaire is a 15-item model, in the proposed general model, we used 9 items: 2, 3, 5, 7, 8, 10, 12, 13, and 15. Other authors have used a varying number of items of the NEP scale; for example, the analysis of Stern et al. (1999) used 7 items. The relationship between biospheric and selfish values in the NEP is once again empirically contrasted, as in other studies (e.g., Stern et al. 1999, de Groot and Steg 2008, Ibtissem 2010, van Riper and Kyle 2014, Choi et al. 2015, Han 2015, Yeboah and Kaplowitz 2016, Kiatkawsin and Han 2017). It is worth noting that the NEP, which is a measure of the endorsement of a “proecological” world view, is very important in this model and has a strong influence on awareness of consequences.

Awareness of consequences is the main construct that hypotheses rely on in this model; it is related to the ascription of responsibility, personal norms, and the intention of practicing ecotourism. The study shows the importance of this construct as an essential element of the model (Ibtissem 2010, Jansson et al. 2010, Choi et al. 2015, Kiatkawsin and Han 2017). In sum, the awareness of consequences influences personal norms, the intention to practice ecotourism, and the assignment of responsibility; the latter also influences personal norms.

Initially, the assignment of responsibility was one of the most important constructs in the model (Han 2015, Kiatkawsin and Han 2017), and the same is true in our proposal (Stern et al. 1999, Kaiser et al. 2005, Steg et al. 2005, de Groot and Steg 2008, Ibtissem 2010, van Riper and Kyle 2014, Choi et al. 2015).

Personal norms, such as the assignment of responsibility, are one of the most important constructs of the model because they are seen as a precursor to proenvironmental behaviors (Stern et al. 1999, Itbissem 2010, Kiatkawsin and Han 2017), forms of travel (Nordlund and Garvill 2003), or the intention to stay in an ecological hotel (Choi et al. 2015). In our model, the results indicate a significant relationship between personal norms and the intention to practice ecotourism, as well as to pay more for it, following the line of previous studies such as Han et al. (2017), Choi et al. (2015), and Yeboah and Kaplowitz (2016).

The subjective norms included in this model or linear framework are adopted from the TPB, and they help us to understand and extend the explanatory framework of the intention of ecotourist behavior intention, following the line of studies such as Goh et al. (2017). Similarly, our model indicates that subjective norms influence personal norms as well as behavior intention (Stern 2000).

Therefore, the intention to practice ecotourism is influenced by awareness of consequences, personal norms, and social norms. Moreover, our research confirms that the intention to practice ecotourism and the intention to pay more for it show a positive relationship, following previous studies by Hultman et al. (2015).

The multigroup analysis of the research indicates that there is no moderating effect in the comparison by country in relation to Chile and Spain. This finding indicates that the model is somewhat robust and, on the other hand, may indicate that the cultural differences between Chile and Spain may not be broad enough in aspects such as moderating ecotourist behavior. We must remember that only the individualism/collectivism and indulgence/control dimensions show dissimilar levels in the two countries; the other dimensions, despite differing, do not have such variant values. The multigroup analysis also indicates that there is no gender moderation effect in any of the hypotheses, which indicates similarity of behavior of the two genders in relation to the general model, despite the differences in masculine/feminine behavior shown in Hofstede’s cultural analysis comparing the two countries.

As is well known, ecotourism is characterized by being more expensive than other kinds of tourism. However, we have demonstrated that ecotourists are willing to pay more for practicing ecotourism, and this intention to pay more has a high impact on personal norms.

Using the data from our study, companies and institutions working in sustainable tourism can attempt to influence tourists’ values (especially biospheric values), beliefs, and attitudes and their intention to undertake ecotourism, thereby improving the marketing and branding of ecotourism products. In this regard, it is necessary to design ecotourism products that provide tourists with a wide range of services on their trips.

Considering that constructs of conscience in consequences and personal norms are the most powerful constructs of the proposed model, ecotourism operators may encourage these attitudes among tourists to enhance their intention to practice ecotourism. They can do this, in particular, by promoting attitudes in favor of sustainable tourism over time through explanatory proposals for environmental education in each of the activities to be carried out, for example, the consumption of CO2 in airplane travel-carbon footprint, local materials used in construction projects, the rational use of energy, and the production of waste, native plants used in the development of gardens, the consumption of local ecological products, decisions on the daily cleaning of hotel accommodation (towel replacement, etc.), visit to local artisans or farmers, or activities in nature). Similarly, operators should discourage the materialistic behavior of tourists in their establishments in order to promote the consumption of ecological tourism in the future, framing these activities in the strategic plan of the company to influence the decision making of tourists.

People who operate ecotourism businesses must pay attention to the environment, fauna and flora, physical spaces, and communities where they develop their ecotourism activities, combining measures that involve promoting education and environmental behavior with activities such as saving water and energy without undermining the quality of activities, catering, and accommodation. Approaches such as environmental education activities at the family level, informational panels on the ecological footprint of transport, and posters on the previous and current use of water and energy may be used. Information about and traceable origin of organic products consumed in establishments or a relationship with the inhabitants of local communities through cultural or educational activities are of interest in this area.

Therefore, an ecotourism company must enhance its environmental reputation through different strategic plans that combine ecotourists’ ecological concerns, business sustainability, and ecological reputation. Ecotourism operators need to invest more resources in increasing ecotourists’ awareness of environmental problems and in reflecting this concern in companies’ green initiatives.

Likewise, advertising campaigns that provide and disseminate information about ecotourism are needed in the countries studied: Chile and Spain. These campaigns should emphasize how ecotourism drives local economies, protects nature, and improves expectations regarding sustainable development among future generations. Thus, it is important to make a special effort in population sectors that are less inclined to undertake ecotourism or ecological tourism and in sectors that have weaker social and environmental values but show a willingness to undertake nature-based tourism and behave ecologically.

To this end, ecotourism operators could also make their ecological efforts known by disseminating proenvironmental management through their channels of communication with consumers (web, social media, brochures, video, audio, etc.).

With regard to prices, ecotourism operators can set certain price increases for the activities in the appropriate percentage range (below 10%, according to Laroche et al. 2001) that makes the increase more acceptable to the majority of potential ecotourism consumers. These higher prices must necessarily be justified to tourists transparently and credibly in a manner that avoids the idea that the additional expense is a form of ecological attraction or, worse, a useless cost or an expenditure with no return.

The experience of people who practice ecotourism is vitally important because it facilitates changes in their values, attitudes and behaviors, and gaining an understanding of this process is imperative (Walker and Moscardo 2014). In addition, ecotourism operators, through various activities before, during, and after a trip, can improve the experiences of ecotourists so that they have a truly impactful experience that influences their vision of the importance of the environment. Operators can also implement experiences through tourist packages that contribute to the environment (Force et al. 2018). Particularly interesting is research on postvisit activities that facilitate the lived learning experiences, enabling the transformation of environmental attitudes and behaviors to extend over time (Ballantyne and Packer 2011).

Regarding the design of public policies for tourism, these should focus on content that reinforces the idea that tourists’ ecological behavior reduces the negative impacts of tourism activities on community environments, the rural world, natural areas, and society. These practices can benefit and help environments that support ecotourism by more effectively conserving, maintaining, and protecting their biological diversity.

LIMITATIONS AND FUTURE AREAS OF RESEARCH

Beyond the empirical contributions of this study, some limitations have been noted that could offer opportunities for future research in the field of tourism. This study enabled a better understanding of the factors that affect the intention to undertake ecotourism and to pay more for this activity. However, because we used only one TPB construct (Choi et al. 2015), using other constructs could be very interesting. Similarly, we focus on understanding the intention of undertaking ecotourism or paying more for it but do not analyze specific ecotourism behaviors (hotels, visits, activities) and do not apply other instruments that could measure ecotourist behavior in the future.

Owing to the importance of rules in this model, we have focused on understanding the importance of personal and subjective rules, which may present an opportunity to deepen the investigation of the role of rules, following Smith and Louis’s (2008) idea of the rules-centered approach. Specifically, it may be of interest to delve more deeply into the classification of descriptive and injunctive norms proposed by Cialdini et al. (1991) in order to gain a better understanding of what people think and do as well as their perception of what behaviors a society approves or does not approve of.

In addition, other aspects that have been studied previously in the literature could be included to understand the antecedents of ecotourism behavior in more detail. For example, it could be very interesting to analyze how the use of informative labels and educational materials influences the ecotourism experience.

Furthermore, because this study is cross-sectional, it would be beneficial to apply it to longer term or longitudinal research. Finally, this cross-cultural study is of two countries that, although on different continents, both have roots in Latin culture. Therefore, it would be interesting to conduct studies on the influence of culture between countries with dissimilar cultures, such as African or Asian countries.
