摘要
绿色发展是当今时代科技革命和产业变革的方向,绿色经济也已成为全球产业竞争重点。基于三阶段DEA模型,测算了2022年中国绿色供应链上市企业的创新效率。研究发现,企业的成立年限、企业规模、股权性质、股权集中度、政府补贴和对外开放水平这些环境变量均会在不同程度上造成投入冗余,降低企业的创新效率。清除环境因素和随机误差的影响之后,60%以上的企业的创新效率呈现了上升趋势,但整体水平并不高。实证结果有助于进一步提升绿色供应链企业的创新效率,也为绿色供应链企业后续的研究提供新的视角。
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.
