3.1. Hypothesis
From the perspective of social learning theory, it is evident that green consumption behavior is jointly influenced by external and individual factors. The proponents of the theory assert that individual behavior is not only unilaterally influenced by external or internal influences, but also that individual behavior, subjective cognition, and the social environment are dynamically interacting and determining each other.
In terms of demographic characteristics, the majority of studies indicate that females, individuals with higher education, youth, and those with middle incomes will engage in more environmentally friendly consumption behaviors. However, there are also studies that conclude that the aforementioned factors are not significantly associated with green consumption behaviors [
46]. Furthermore, certain scholars have also determined that occupation has a substantial impact on green consumption behavior. Specifically, employees of state-owned enterprises and civil servants exhibit a higher level of green consumption behavior, whereas unemployed residents exhibit the lowest rates of green consumption behavior. Nevertheless, there are no pertinent hypotheses, as the demographic characteristics of the attributes are not aptly described on a scale.
Psychological factors, such as moral reflection and a sense of responsibility, can reflect an individual’s altruistic values. Individuals with strong altruistic values will weigh the benefits of green consumption from the perspective of the social group and will sacrifice their personal interests to protect the environment when their personal interests are at odds with the interests of society [
47]. Furthermore, the perception of social responsibility can also impact the consumption decisions of residents, and those who prioritize environmental and social responsibility are more likely to engage in environmentally friendly consumption habits. The Theory of Planned Behavior posits that an individual’s behavioral intention is influenced by attitudes, subjective norms, and perceived behavioral control. Attitudes refer to an individual’s overall assessment of a behavior, subjective norms to an individual’s perceived social pressures, and perceived behavioral control to an individual’s beliefs about their capacity to execute the behavior. The Theory of Planned Behavior can be used to infer the impact of psychological factors on green consumption behaviors [
48,
49,
50]. Research has indicated that environmentally conscious consumers are more inclined to acquire green products, regardless of their increased cost in comparison to comparable non-green products [
51]. Additionally, it has been determined that green consumer behavior can be positively impacted by ethical reflection, trust in the product, and individual responsibility [
52]. Furthermore, environmental emotions and collectivist values can also substantially and positively influence green consumption intentions, thereby influencing green consumption behavior [
53,
54]. Consequently, in this investigation, we suggest the subsequent hypotheses: H1–H4: Psychological factors have a significant positive effect on green consumption behavior.
Stern developed the value-belief-norm theory by integrating value theory and new environmental paradigm theory on the premise of norm activation theory [
55]. The value-belief-norm theory commences with values, progresses through beliefs regarding the relationship between humans and nature, and ultimately culminates in the individual’s beliefs regarding the repercussions of poor behavior and their personal responsibility. This ultimately activates personal norms and reinforces the individual’s environmental behavior. The values-beliefs-norms theory expands the research value of environmental behavior by incorporating values and environmental responsibility into the analytical model, which are considered to be the primary variables in explaining green consumption [
56]. The existing literature has extensively discussed the relationship between environmental cognition and environmental behavior, and environmental cognition is a quantitative expression of consumers’ environmental knowledge and awareness. However, no unified conclusion has been reached. For instance, certain studies have indicated that environmental awareness is the most effective factor in influencing environmentally friendly behavior and can effectively encourage individuals to behave in an environmentally friendly manner. However, other studies have discovered that this relationship may be weak [
57,
58,
59,
60]. The study of individual consumption behavior from the perspective of values has been widely embraced by academics, as it is a value-oriented behavior. Several studies have demonstrated that consumers’ green consumption behavior can be substantially influenced by the adoption of accurate environmental values [
61]. Environmental cognition has the potential to enhance residents’ environmental awareness, reduce cognitive dissonance, and increase their sense of social responsibility. This, in turn, influences residents’ lifestyle decisions. As consumers’ environmental awareness improves, they will become more engaged in environmental issues and will pay more attention to them. Moreover, certain scholars contend that factors such as green consumption attitudes will serve as a chain mediating factor between the two [
62,
63]. In summary, environmental cognition objectively encourages the adoption and proliferation of green consumption behaviors and enhancing public environmental awareness is a critical method for promoting green consumption. Consequently, in this investigation, we suggest the subsequent hypotheses: H5–H8: Environmental awareness has a significant positive effect on green consumption behavior.
It’s evident from supply and demand theory that price and consumption have an inverse relationship. Higher prices result in lower consumption, while lower prices lead to higher consumption. Market incentives for green consumption can be seen to make green products more affordable, which may encourage more people to engage in green consumption behavior [
64]. According to the theory of diminishing marginal benefits, when consumption increases, the marginal utility initially increases but eventually reaches a point where it starts to decrease. These variations in economic development levels result in varying impacts of market incentives on different regions. Furthermore, market incentives are frequently influenced by government actions, which indirectly encourage environmentally friendly consumer behavior through policies like tax incentives for protecting the environment. As a result, consumers often choose to purchase subsidized green products due to their trust in the government. The correlation between market incentives and green consumption behavior has been investigated by numerous academicians. For instance, French scholars have discovered that the provision of economic subsidies for low-emission cars by the state results in an increase in the number of individuals purchasing such vehicles [
65]. Additionally, there are scholars who, through economic and psychological analyses, believe that both time and money costs will have a certain impact on green consumption behavior and that enterprises and the government can leverage these resources to encourage residents to engage in green consumption behavior [
66,
67]. Certain studies have also discovered that consumers are frequently inclined to make purchases when the premium price of green products is low [
68]. Consequently, in this investigation, we suggest the subsequent hypotheses: H9–H12: Market incentives have a significant positive effect on green consumption behavior.
According to the peer effect in psychology, individuals in a specific social milieu will alter their behavioral attitudes and other characteristics as a result of the influence of their peers [
69]. In 1993, Manski proposed that the explanations for the tendency of different individuals within the same group to exhibit similar behaviors are divided into three categories: endogenous, exogenous, and correlative effects. The endogenous effect is the mechanism by which individual behavior is influenced by changes in group behavior, individual decisions are based on their interactions or interrelations with their peers. The exogenous effect is the mechanism by which individual behavior is influenced by changes in the characteristics of the group. The correlation effect is the mechanism by which individuals in the same group tend to exhibit similar behaviors due to their similar individual characteristics or being in similar environments [
70]. The Theory of Planned Behavior also posits that subjective norms are the social pressure experienced by individuals. It posits that when members of a social group tend to purchase green products, other individuals will be influenced to conform to the social norms and develop a sense of social identity. Furthermore, groups that engage in green consumption behaviors establish a shared social identity, which in turn motivates them to adopt green consumption behaviors and increases their sense of responsibility and desire to participate. Consequently, the efficacy of social pressure in encouraging consumers to adopt green consumption behaviors will be enhanced by the growing awareness of environmental issues and the proliferation of environmentally conscious organizations. Other academicians have discovered that consumers are more likely to purchase organic food when others are present or when the majority of individuals purchase organic food [
71]. It has also been demonstrated that the act of purchasing in pairs has a beneficial effect on one’s green consumption behavior, particularly when it is conducted with family members [
72]. Consequently, we suggest the following hypothesis in this investigation: H13–H16: Social pressure can have a significant positive effect on green consumption behavior.
Green information is a critical external factor in the promotion of green consumption behavior, as it effectively presents consumers with information about green products and conveys green consumption and life concepts. The dissemination of green information can significantly increase consumers’ self-efficacy and foster the belief that they can make a positive impact on the environment through green consumption. This sense of self-assurance can assist consumers in surmounting obstacles and doubts and implementing green consumption behaviors more actively [
73]. Additionally, consumers are able to more effectively manage their own behavior by comprehending green information, which allows them to make purchasing decisions based on their own environmental values and rational judgment. Green information can also effectively influence consumers’ psychological factors and environmental cognition, thereby promoting their green consumption behavior, to a certain extent. Some scholars have discovered that consumers’ preferences and willingness to pay for green food are significantly increased by green identity labels when environmental information is implemented [
74]. Additionally, the effective transmission of product environmental information is essential for the promotion of green consumption behavior [
75]. In addition, residents’ attitudes and behaviors regarding green consumption can be significantly influenced by government and media campaigns on environmental issues [
76,
77,
78]. Additionally, companies can employ information interventions to direct consumers toward green consumption behaviors [
79]. Winett et al. contend that media campaigns are a successful framework for behavioral change because they incorporate marketing, communication, social learning, and behavioral analysis. framework. In the same vein, the media’s interactive, global, and rapid penetration enables the intertwining of individual norms and behaviors with those of others and society as a whole, thereby influencing individual behavior [
80]. Consequently, we suggest the following hypothesis in this investigation: H17–H20: Information boosting has a significant positive effect on green consumption behavior.
The influencing factors of green consumption behavior are summarized by combining the five sets of hypotheses supported by the aforementioned theories and literature review, as well as the theoretical framework of planned behavior. The influencing factors of green consumption behavior are subsequently classified into two major types: internal and external factors. The internal factors include psychological factors and environmental cognition. Furthermore, the psychological factors in this study primarily reflect the residents’ moral reflection, sense of individual responsibility, and level of trust in the organization. The environmental cognition primarily reflects the residents’ environmental literacy, the extent of their environmental knowledge mastery, and a higher level of professionalism. Market incentives, social pressure, and information increases are all examples of external factors. Consequently, this investigation formulates a relationship diagram that illustrates the impact of psychological factors, environmental cognition, market incentives, social promotion, information bolstering, and a variety of green consumption behaviors. In conjunction with the three models of green consumption behavior mentioned earlier, this paper categorizes green consumption behavior into four categories. The first three categories are daily environmental protection behavior, consumption of green products, and participation in the sharing economy. Additionally, the composition of green consumption behavior includes green consumption for production, as a significant number of rural residents engage in production activities, which is also one of the most significant differences between rural and urban residents.
Figure 1 illustrates the structural paradigm of green consumption behavior.
Since green consumer behavior is divided into four different categories, each of the five sets of hypotheses presented above has four different branches, so this paper proposes the following 20 specific hypotheses as follows: H1: psychological factors have a major beneficial impact on daily environmental behavior; H2: the consumption of green products is significantly positively influenced by psychological factors; H3: the sharing economy’s engagement is significantly positively impacted by psychological factors; H4: psychological factors positively and significantly impact the green consumption behavior in production; H5: environmental awareness has a major positive impact on daily environmental behavior; H6: the consumption of green products is significantly positively impacted by environmental awareness; H7: environmental awareness significantly positively impact engagement in the sharing economy; H8: the green consumption behavior in production is significantly positively impacted by environmental awareness; H9: market incentives have a major positive impact on daily environmental behavior; H10: the consumption of green products is significantly positively impacted by market incentives; H11: the sharing economy’s engagement is significantly positively impacted by market incentives; H12: the green consumption behavior in production is significantly positively impacted by market incentives; H13: daily environmental behavior is significantly positively impacted by social pressure; H14: the consumption of green products is significantly positively impacted by social pressure; H15: engagement in the sharing economy is significantly positively impacted by social pressure; H16: the green consumption behavior in production is significantly positively impacted by social pressure; H17: daily environmental behavior is significantly positively impacted by information boost; H18: consumption of green products is significantly positively impacted by information boost; H19: engagement in the sharing economy is significantly positively impacted by information boost; H20: the green consumption behavior in production is significantly positively impacted by the information boost.
3.2. Questionnaire Design and Collection
The participants of this research are income- and age-variable rural inhabitants hailing from the eastern, western, central, and northeastern regions of China. Following the determination of the target population, the sampling process took into account scientific validity, representativeness, cost, and other comprehensive considerations to ensure that the sampled units in the overall uniform distribution were representative. As shown in
Table 1, the sample size for each region in this paper is calculated using the proportion of rural residents in the four regions to the total number of rural residents in the country.
The maximum allowable error of 5%, the confidence level of the estimates being 99%, which translates to a Z-statistic of approximately 2.68, and assuming that the population’s overall standard deviation is equal to 0.5, we require a minimum sample size of 666 according to the sample size Formula (1) to improve the precision of the estimates.
Moreover, the number of questionnaires must be more than ten times the number of questions; since this questionnaire has 42 questions, the sample size must be more than 420. Using the two sample size determination techniques mentioned above, combined with the cost of time and the financial implications, this paper ultimately opted to gather roughly 1000 valid samples of data processing to guarantee the representation and accuracy of the data. Furthermore, it is important to ensure that the geographical distribution of the questionnaire respondents in this paper closely reflects the actual distribution of China’s rural population. It is also crucial to maintain a balanced gender ratio, cover all age groups, and have educational and income levels that are representative of rural areas in China. Additionally, it is necessary to include a wide range of occupations to encompass all types of jobs.
The data collection period for this survey is from 1 February to 29 February 2024. The questionnaire data is collected using a combination of online and offline methods. The online questionnaire uses the Sojump platform. The online questionnaire uses the “whether you live in an urban or rural area” question to eliminate the questionnaire of urban residents. Regarding the online questionnaire’s data quality control, to begin with, to prevent redundant responses from the same participant, each electronic device and IP address was restricted to providing an answer only once; Furthermore, surveys that were not meticulously completed were excluded (e.g., responses to similar questions that exhibited an excessive amount of variation, etc.). Ultimately, the questionnaires that had a higher number of missing values for scale data were excluded, while those with a lower number of missing values were filled in using the mean-filling method.
The survey scale for this study was the Likert scale, which is widely recognized and used both domestically and internationally. The majority of the scales were developed from mature scales in domestic and international literature, and a translation and back-translation method were used to ensure the accuracy of the scales in foreign literature. The scales measured nine different aspects in total, including environmental awareness, psychological factors, market incentives, social promotion, information boost, and the four categories of green consumption behaviors.
This investigation implemented a five-point Likert scale for scoring, with “1–5” representing “strongly disagree” to “strongly agree”. The mean was computed to determine a score for each aspect [
81]. This paper also divides green consumer behavior into four major parts, namely sharing economy, green consumption in production, consumption of green products, and daily environmental behavior. This is due to the fact that green consumer behavior encompasses a broad range of topics and the influencing factors of different aspects may vary to a certain extent. The questionnaire contains a total of 42 questions.
The pre-survey consisted of the collection of 90 valid questionnaires, which successfully passed the reliability test. The questionnaire questions were subsequently slightly modified in accordance with the data acquired during the pre-survey, and the final questionnaire was subsequently developed.
In terms of the psychological factors dimension scale, including personal responsibility and product trust, the scale is based on the 2018 China Comprehensive Social Survey questionnaire, which includes four questions, including “You trust organizations to rate green products” and “You believe that the quality of green products is higher than that of traditional products”; these questions are scored on a 5-point Likert scale, with “1–5” indicating “strongly disagree”—“strongly agree”.
The environmental awareness dimension scale primarily assesses the environmental literacy and environmental values of residents. The scale is derived from the 2018 China General Social Survey questionnaire and comprises four inquiries, such as “All organisms in nature are interdependent” and “You are concerned with the environment and strive to preserve its quality”. The responses to these inquiries were evaluated on a five-point Likert scale, with scores ranging from one to five representing “strongly disagree” to “strongly agree”.
The market incentive dimension scale is derived from the 2018 China General Social Survey questionnaire, which is primarily utilized to evaluate the influence of price and price compensation on green consumption behavior. The questionnaire includes four questions, such as “If green products have price subsidies, it will make you want to buy them” and “You care a lot about the price of green products”. These inquiries were evaluated on a five-point Likert scale, with scores ranging from one to five representing “strongly disagree” to “strongly agree”.
The social pressure dimension scale is primarily based on the 2018 China General Social Survey questionnaire, which assesses the impact of peer effects on the green consumption behavior of residents. It comprises three inquiries, one of which is “You are more inclined to purchase environmentally friendly products when others are present”. The responses to these inquiries are evaluated on a five-point Likert scale, with scores ranging from one to five representing “strongly disagree” to “strongly agree”.
The information boost dimension scale is derived from the scale developed by Lee and Kim et al., which primarily assesses the influence of government or media publicity on environmental information and green consumption behavior. The scale comprises four items, such as “The media promotes the establishment of a sustainable living environment” and “You have access to a wealth of information regarding environmental protection and green consumption in your daily life”. The responses to these inquiries were evaluated on a five-point Likert scale, with scores ranging from one to five representing “strongly disagree” to “strongly agree”.
The scale of green consumption behavior is composed of four components, and its design is informed by the 2018 China Comprehensive Social Survey questionnaire and the research of Lee and Han et al. [
82]. Firstly, it primarily assesses the level of participation of residents in daily environmental behavior, which includes three questions such as “You have the habit of saving water and electricity in your daily life”. Secondly, it primarily assesses residents’ willingness to engage in green product consumption, which includes four questions, such as “You will select solar lamps and renewable energy products to replace traditional energy products to the greatest extent possible”. Thirdly, it primarily assesses residents’ willingness to participate in the sharing economy, which includes four questions, such as “When traveling a shorter distance, you will opt to walk or share a bike instead of a car”. Fourthly, it primarily assesses the willingness of residents to engage in green consumption in production, which encompasses three items, including “If you were a farmer, you would use green fertilizer whenever possible”. The Likert scale was used to evaluate these items, with scores ranging from one to five representing “strongly disagree” to “strongly agree”.
