Research on Innovation Efficiency Evaluation of Green Supply Chain Enterprises:An Empirical Analysis Based on Three-stage DEA
Green development is the direction of scientific and technological revolution and industrial transformation in today's era,and green economy has also become the focus of global industrial competition.Based on a three-stage DEA model,this study measures the innovation efficiency of listed companies in China's green supply chain in 2022.The results show that the environmental variables such as the establishment period,the size of the enterprise,the nature of equity,the concentration of equity,the level of government subsidies and the level of opening up to the outside world will cause investment redundancy to varying degrees and reduce the innovation efficiency of enterprises.After removing the influence of environmental factors and random errors,more than 60%of enterprises showed an upward trend in innovation efficiency,but the overall level was not high.The empirical results of this paper are helpful to further improve the innovation efficiency of green supply chain enterprises,and also provide a new perspective for the follow-up research of green supply chain enterprises.
