7. Conclusions
Retailers, especially food retailers, operate one of the most complex SCs. Yet, GSCM research tends to focus on the perspectives of manufacturing companies or secondary data analysis of, for example, green activities that retailers publish on their corporate web pages or in CSR reports. The relationship between internal and external greening of the SC has not been conceptualized or empirically tested in the food retail setting. Therefore, this study aimed to empirically analyze the relationship between green in-store practices, GSCM practices and environmental and economic performance in the food retail industry. To do so, structural equation modeling, was applied, assessing the links among green in-store practices, GSCM practice and SC performance in the food retail context. Given the lack of studies on relationships between greening instore activities, GSCM practices and overall performance of the food retail SC, this study empirically contributes to the growing discussion on retail sustainability issues from the narrow focus of retailers as focal companies in SCM. This provides the answer to our research question. Green in-store processes serve as antecedents for GSCM-related processes, which are operationalized in the constructs of green logistics, green purchasing and collaboration with suppliers. These constructs drive respective environmental and then also economic outcomes. This opens up further questions on how related resources and capabilities would have be developed in retailing so to further drive GSCM in such service contexts.
