自愿参与型环境规制、创新能力与绿色技术创新 ——来自中国涉农微观企业的数据分析

Voluntary Participatory Environmental Regulation, Innovation Capability and Green Technology Innovation:A Study Based on Micro-data of Chinese Agriculture-related Enterprises

摘要:

自愿参与型环境规制能否有助于推动涉农企业的绿色技术创新水平，是极具研究价值的现实问题之一，而学术界对农企绿色创新以及自愿型制度构建讨论较少。本文基于2010—2019年273家沪深A股上市企业微观数据，采用负二项回归模型分析了我国涉农上市企业在自愿参与型环境规制下绿色技术创新行为特征。结果发现，一是，在自愿参与型环境规制下企业绿色创新活动具有“重实用轻发明”的异质性特征，对绿色发明专利的抑制作用和对实用外观专利的提升作用显著，这一结论是在经过内生性处理和稳健性检验后仍然成立；二是，环境管理和创新能力的交互项结果表明，涉农企业的环境管理意识和创新能力有机结合后，自愿参与型环境规制对企业绿色技术创新的影响由负转正，而且积极作用显著。三是，为我国农企提高环境管理意识以及政府优化农业环境治理路径提供了微观证据。

Abstract:

Based on data of 273 A-share listed companies from 2010 to 2019, this paper uses a negative binomial regression model to analyze the characteristics of green technology innovation behavior of my country's agricultural listed companies under voluntary environmental regulations. The results found that, first, under the voluntary environmental regulation, the green innovation activities of enterprises have the heterogeneous characteristics of “emphasizing utility over invention”. Environmental regulation has a significant effect on increasing the number of utility appearance patents and reducing the number of invention patents. This conclusion is still established after endogenous treatment and robustness test; second, the interactive item results of environmental management and innovation capabilities show that after the environmental management awareness and innovation foundation of agricultural enterprises are organically combined, voluntary environmental regulations have an impact on the company’s green technology That impact has changed from negative to significantly positive. The conclusion provide micro-evidence for my country's agricultural enterprises to improve their environmental management awareness and the government to optimize the path of agricultural environmental governance.
