摘要
利用2016—2020年京津冀上市公司面板数据,基于DEA-Malmquist指数分解模型,测量技术创新效率,检验2018年以来实施的环境保护税政策对京津冀地区企业创新的影响。实证结果表明:2018年环境保护税法的实施对京津冀上市公司的技术创新效率具有显著正向影响;对规模效率和全要素生产率的影响并不显著。基于制造业和非制造业的辅证检验也证明了以上假设。基于此,提出提高环境保护税的征收力度、促进企业加快升级转型、在环境保护税的基础上建立创新激励机制、减小因环境技术创新而加大的成本压力以配合"双碳"目标等政策建议。
This paper,based on the DEA Malmquist index decomposition model,uses the panel data of the listed companies in Beijing-Tianjin-Hebei from 2016 to 2020 to measurethe efficiency of technological innovation and test the impact of the environmental protection tax policy implemented since 2018 on enterprise innovation in Beijing-Tianjin-Hebei.The empirical results indicate that the implementation of the environmental protection tax law in 2018 has a significant positive impact on the technological innovation efficiency of the listed companies in Beijing-Tianjin-Hebei while the impact on scale efficiency and total factor productivity is the other way around.The supplementary evidence test based on manufacturing and non manufacturing also proves the above hypothesis.Based on this,this paper puts forward some policy suggestions,such as improving the collection of environmental protection tax,promoting enterprises to accelerate upgrading and transformation,establishing the innovation incentive mechanism based on environmental protection tax,reducing the increased cost pressure generated from environmental technology innovation,so as to cooperate with the"double carbon"goal.
