环境规制与行业异质性对制造业企业技术创新的影响——基于我国沿海与内陆地区的比较

Influence of Environmental Regulation and Industry Heterogeneity on Technological Innovation of Manufacturing Enterprises: Based on the Comparison Between Coastal and Inland Areas of China

摘要:

基于行业异质性视角,以2010年—2015年我国省级制造业规模以上企业为样本,将环境规制划分为正式型与非正式型两类,对比分析了沿海与内陆地区环境规制、行业异质性对企业技术创新影响的差异。研究发现：(1)从制造业全行业来看,正式型环境规制对技术创新的影响作用在沿海与内陆地区均显著为正；非正式型环境规制对技术创新的影响作用在沿海地区显著为正,在内陆地区作用不显著；环境规制强度对技术创新的影响作用在沿海地区显著为负,在内陆地区显著为正。(2)环境规制对高污染行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。(3)环境规制对高搬迁成本行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。

Abstract:

Based on the industrial heterogeneity, dividing environmental regulation into formal and informal environment regulation, it makes a comparative analysis of the impact of environmental regulation and industrial heterogeneity on manufacturing enterprises between coastal and inland regions through the provincial data in China from 2010 to 2015. The results show that:(1)From the perspective of whole industry, the impact of formal environmental regulation on technological innovation is significantly positive in both coastal and inland regions; informal environmental regulation has positive effect in coastal regions and is not significant in inland regions; environmental regulation intensity plays a significantly negative role in coastal regions but plays a significantly positive role in inland regions.(2)The effect of environmental regulation on technological innovation of high pollution industry is significantly positive in coastal regions but is significantly negative in inland regions. (3)The influence of environmental regulation on technological innovation of high relocation cost industry is significantly positive in coastal regions but is significantly negative in inland regions.
