Abstract: The recycling and remanufacturing of waste products can not only reduce environmental pollution and save resources, but also bring additional economic benefits to enterprises. Therefore, the closed-loop supply chain (CLSC) management has become an important development strategy for many large enterprises. At the same time, in addition to pursuing profits, more and more enterprises begin to pay attention to corporate social responsibility (CSR). However, the existing researches to analyze the impact of CSR on supply chain operation either separately from the macro-strategic level or from the micro-investment perspective, and few studies consider the two different forms of CSR behaviors at the same time. Secondly, the existing studies generally ignore the fact that the motivation of members to fulfill CSR may vary due to their different position in the CLSC. Therefore, it has great theoretical and practical significance to study the operation and coordination problem of CLSC considering CSR behaviors.
