Abstract
Quality information sharing can promote close collaboration between all aspects of the supply chain and provide a strong guarantee for the sustainable development of the new energy vehicle (NEV) industry. However, quality information sharing in the NEV supply chain faces obstacles such as management challenges and lack of trust among supply chain members. In view of this, the objective of this study is to design an analytical framework to promote the sharing of related critical quality information in the NEV supply chain. This study aims to establish the framework by following a closed loop logic chain, including identification, economic analysis and performance evaluation. To improve the pertinence and practicability of this study, the NEV enterprise W was selected for case study.
