中国工业环境规制成本对科技创新的敏感性研究*

Sensitivity of China's Industrial Environmental Regulation Costs for Technological Innovation

摘要:

内容提要：本文基于方向性距离函数,测算了中国工业行业环境规制成本,发现其行业异质性显著,而不存在显著的污染偏好性。面板数据模型回归结果表明,工业环境规制成本对科技创新具有很强的敏感性,但是对不同科技创新指标的敏感程度存在差异。企业科技活动增加,科技从业人员比重提高,企业专利数量增加都对降低环境规制成本起到积极作用；而新产品收入比重和研发经费投入比重对降低环境规制成本的作用具有显著的门槛特征。

Abstract:

This paper applied the directional distance function estimate China’s industrial environmental regulation costs, found that environmental regulation cost exist significant heterogeneity among the industry, but showed no significant contamination preference. The panel data model regression results show that, industrial environment regulation costs is very sensitive to scientific and technological innovation, but there are differences in the sensitivity to different scientific and technological innovation indicators. Increasing scientific and technological activities, increasing the proportion of R D personnel, or increasing patents play a positive role to reduce environmental regulation costs. New revenue share and the proportion of R D funding have significant threshold characteristics to reduce environmental regulation costs.
