Abstract
Many consumers are concerned about environmental issues and have expressed interest in purchasing green products. However, actual sales of green products are still not as high as expected. Therefore, marketers of green products may need to investigate the factors driving green purchase behaviors. In this study, we proposed an extended theory of planned behavior (TPB) model that links consumers’ environmental concerns, perceived image of the company, consumer innovativeness, and environmental knowledge with green product purchase behavior. We applied a quantitative approach to collect the data via online questionnaires through Amazon MTurk. With 974 useable samples, the data were analyzed with structural equation modeling (SEM) using Smart PLS. The results showed that green purchase intention positively and significantly affects green purchase behavior. Moreover, the multigroup analysis revealed that the direct influence of green purchase intention on green purchase behavior is higher in developing countries than in developed countries. Regarding the direct effect on green purchase intention, attitude toward green products, perceived consumer effectiveness (PCE), environmental concern, and company’s perceived green image are significant antecedents of the intention to purchase, with attitude toward green products being the most robust antecedent among the three. However, subjective norms do not act as a direct antecedent of purchase intention. For the indirect effect on green purchase intention, four main antecedents (attitude toward green products, subjective norms, PCE, and environmental concerns) indirectly impact purchase intention via the mediating role of the perceived green image of the company. This study contributes to existing literatures via extending the TPB model. Regarding attitude-intention-behavior model, we found that environmental concern complements the model as an antecedent of green purchase intention. Moreover, a company’s perceived green image mediates the relationship between four antecedents and green purchase intention. Therefore, marketers of green products may also enhance future purchases by promoting the green image of the company. Particularly, we found that environmental knowledge positively moderates the relationship between environmental concern and a company’s perceived green image. We added on the empirical evidence that PCE plays a crucial role in stimulating green purchases as its direct positive influence on green purchase behavior is larger than that of green purchase intention. Moreover, consumer innovativeness positively moderates the relationship between PCE and green purchase intention.
Highlights
Green consumers may choose to purchase green products to minimize pollution and mitigate the global environmental crisis [1]
Innovativeness negatively moderated the relationship between attitude toward green products and green purchase intention (ß = −0.191, t = 4.387, p < 0.001), Hypothesis 8a (H8a) is not supported as we hypothesized that the moderating effect should be in the positive direction
Our findings showed that all four antecedents, including attitude toward green products in Hypothesis 6a (H6a), subjective norms in H6b, perceived consumer effectiveness in Hypothesis 6c (H6c), and environmental concerns in Hypothesis 6d (H6d), significantly and positively influenced a company’s perceived green image
Summary
Green consumers may choose to purchase green products to minimize pollution and mitigate the global environmental crisis [1]. Green consumers may choose recycled or remanufactured products to contribute to green development toward global sustainability [3]. In the green product context, attitude has been the most important determinant of purchase intention. Previous studies revealed the discrepancy between consumers’ favorable attitude toward green consumption and actual purchase behavior [5]. The discrepancy between consumers’ green positive attitudes toward the environmentally-friendly products and the purchase of green products has been studied in previous literatures [7,8,9]. Prior studies have attempted to close the “green attitude-behavior gap” by employing the TPB model [10,11]. Based on TPB, it has been proved that green purchase intention acts as the mediator of green attitudes and green purchase [12,13,14], it is crucial to establish green purchase intention among consumers to create opportunities for green products
