Efficiency of lean practices and blockchain combinations for green supplier integration improvements in sustainable development

Previous studies indicate that green supplier integration can promote supplier knowledge sharing as a core resource and capability to strengthen supply chain resilience and achieve green performance for sustainable development. However, due to the lack of an effective approach and technology to improve green supplier integration, it is difficult for suppliers to promote or even maintain sharing. Few studies note that green supplier integration through lean practices may efficiently promote supplier knowledge sharing, and blockchain combinations may produce efficiencies in maintaining supplier knowledge sharing intention. However, there are still disputes and a lack of deep verification. Thus, this study aims to explore the following questions. First, when green supplier integration is improved through lean practices, can it promote supplier knowledge sharing and further strengthen supply chain resilience and green performance? Second, to what extent do blockchain combinations moderate the relationship between supplier knowledge sharing and supply chain resilience and why? Based on the natural resource-based view and knowledge-based view, this study builds a theoretical framework and verifies it using PLS-SEM based on 214 Chinese manufacturers. The results of our analysis show that suppliers' knowledge sharing with manufacturers can certainly be promoted when lean practices are adopted to improve green supplier integration. In addition, blockchain combinations can certainly maintain supplier knowledge sharing intention and ensure that supply chain resilience related to prevention is continuously strengthened. In sum, our findings make useful contributions to the literature on the efficiencies of lean practices and blockchain combinations in the context of green supplier integration.
