Green Supply Chain Management and Its Impact on Consumer Purchase Decision as a Marketing Strategy: Applying the Theory of Planned Behavior

This study examines the impact of green supply chain management (GSCM) on consumers environmentally friendly purchase behavior. We surveyed 283 consumers and analyzed the data using SPSS 18.0, AMOS 18.0, and verified them with structural equation modeling. To support the primary data analysis results, we conducted focus group interviews (FGIs) of 16 consumers. According to the primary data analysis, consumers' subjective norms and perceived behavioral control positively influence GSCM. However, attitude did not have a significant influence. In the FGI, consumers show a highly positive attitude and purchase intention toward the GSCM of companies. However, they exhibit mistrust and lower purchase intentions toward advertising or marketing campaigns promoting GSCM to consumers. In contrast, the influence of subjective norms was found to be different for different products. In addition, a high price-regarded as the biggest barrier among perceived control factors-raises purchase intentions if consumers are provided with good and transparent information about green products. Thus, this study buttresses the fact that if a company uses GSCM practices as an eco-friendly marketing strategy that reduces consumer distrust and considers product characteristics, it can have a positive effect on consumers' decision to purchase eco-friendly products.
