The complementarity of green supply chain management practices and the impact on environmental performance

Abstract Rising concerns about environmental warnings have forced manufacturers to try to implement environmental management solutions. The green supply chain management approach has received much attention as a comprehensive environmental management perspective that encompasses all flows from suppliers to producers and ultimately to consumers. The purpose of this study is to investigate the collective competence of domestic and foreign green supply chain management practices on two aspects of environmental performance: environmental impacts and environmental cost savings. Green supply chain management has been proposed as a collective competency that has four components: "environmental management systems, environmental design, resource reduction and external environmental practices." The statistical population of the study was the number of industrial companies in Neishabour, which was 163. There were 163 questionnaires sent via the Internet link, of which 125 were willing to answer and 5 were incomplete, and finally 120 questionnaires were analyzed. In the present study, two methods of library and field and questionnaire distribution have been used to collect the desired information. Our research had 5 hypotheses that were tested. Descriptive statistics include frequency and mean tables and standard deviation using SPSS software. At the inferential level, the structural equation model with PLS software has been used. The results showed that the standard coefficient of 0.52 showed that there is a statistically significant relationship between internal management and environmental performance. There is also a significant and positive relationship between green purchasing and environmental performance. There is a positive and significant relationship between customer variability and environmental performance. Also, there is a positive and significant relationship between cooperation with customers and environmental performance, and finally, there is a direct and significant relationship between the variable of ecological design (ecology) and environmental performance. In general, the results indicate that GSCM-mediated components lead to better environmental performance. Therefore, managers should pay attention to the implementation of GSCM practices.
