供应链视角下轨道交通产业低碳转型评价研究OA北大核心

The rail transit industry is an important industry for carbon emission reduction.Under the background of carbon peaking and carbon neutrality goal,its low-carbon transformation is of great significance to promote the high-quality development of China's economy.Approaching from the perspective of the cluster supply chain,this paper constructed an evaluation index system in terms of low-carbon production,low-carbon innovation,low-carbon management,low-carbon environment,and low-carbon operation.The combined weights of indexes were determined with the AHP method coupled with the improved CRITIC method.At the same time,the paper introduced the level measurement model based on the TOPSIS method,the coupling coordination degree model,and the obstacle degree model to evaluate the low-carbon transformation status of the rail transit industry.Finally,the paper conducted empirical research on Chengdu's rail transit industry from 2012 to 2021.The results show that the level of low-carbon transformation of the Chengdu rail transit industry has been generally on the rise with an average annual increase of 11.4%.The coupling coordination degree has increased significantly,and the coordination level has improved from reluctant imbalance to good coordination.Low-carbon production,low-carbon innovation,and low-carbon operation are the main obstacles in the process of low-carbon transformation.Specifically,the cost optimization of the supply chain of the rail transit industry is the focused enhancement direction in the future.
