Research On Performance Evaluation Of Green Supply Chain Enterprises From The Perspective Of Total Factor

With the growing economic base of our country,enterprises and society pay more attention to environmental protection and sustainable development.Greening has become a new requirement for enterprise development.Comprehensive implementation of green manufacturing has become an important choice for China to participate in international competition and improve competitiveness.The supply chain has gradually transformed into a green supply chain in the context of international environmental change,national policy guidance,and its own green environmental awareness.The green supply chain is the product of the combination of green manufacturing theory and supply chain management technology.Scientific and effective evaluation and management of green supply chain enterprises is conducive to supply chain information feedback and adjustment of various links to form a closed-loop green supply chain system,and to minimize the negative effect on the environment and society,thereby to improve the efficiency of green supply chain enterprises and achieve green and sustainable development of enterprises and society.Under the guidance of the theoretical basis of total factor and sustainable development,this study starts from the perspective of total factors,selects the green supply chain management demonstration enterprise publicized by the Ministry of Industry and Information Technology as the research object.Firstly,using the four-stage DEA method and Malmquist index to measure and analyze the total factor efficiency of 10 green supply chain management demonstration enterprises listed in A-shares in 2014-2018.Secondly,deconstructing the total factor efficiency of green supply chain enterprises into the total factor management efficiency and the total factor environmental efficiency of green supply chain enterprises to identify improvement strategies and mechanisms of exogenous environmental variables.And the roots of inefficiency of green supply chain enterprises are explored from the dual perspectives of management and environment.Then the Malmquist index is used to investigate the dynamic changes and decomposition of the total factor efficiency of green supply chain enterprises,and to explore the factors affecting the efficiency of total factor efficiency.Finally,it proposes reasonable and effective suggestions for strengthening green supply chain management,improving the development environment of enterprises,and improving the total factor efficiency of green supply chain enterprises.Then to lead the green transformation of relevant industries,promote the construction of green manufacturing systems,and accelerate the construction of ecological civilization.The study found that: First,the total factor efficiency value of green supply chain enterprises is between 0.73-0.85,showing a trend of first decline and then rising during 2014-2018.There is room for improvement of 15%-27%,and the development potential is huge.Second,Jiuyang and Nuoli shares have the highest average total factor efficiency of 1,while Zhenhua Heavy Industry has the lowest average total factor efficiency of 0.490.The highest and the lowest efficiency value are twice as large,which reflects the imbalance in the development of green supply chain enterprises.Third,the total factor management efficiency is significantly higher than total factor efficiency of green supply chain enterprises.The exogenous environment has a negative impact on the total factor efficiency of green supply chain enterprises.There is a bias in the evaluation results of ignoring the external environment.Fourth,Jiuyang and Nuoli are at the forefront of the total factor efficiency and total factor management efficiency of green supply chain enterprises;the inefficiency of Goldwind's supply chain is affected by the external environment;Haier Zhijia has inefficiencies in green supply chain management;Weichai Power,Snowman,Sany Heavy Industry,TBEA,Zhenhua Heavy Industry and Sichuan Changhong all have different levels of management inefficiency and environmental inefficiency.Fifth,the GDP,the population at the end of the year,and the proportion of authorized patent applications of the region where the enterprise is located are negatively correlated with the slack of input variables.The higher the external environment level is,the lower the redundancy of enterprise investment will be.The higher the level of external environment,the lower the enterprise's input redundancy.Sixth,the change of the average total factor efficiency of green supply chain enterprises has decreased by 1.8%,and technological progress is the main influencing factor.
