环境分权下科技创新与地区生态福利绩效

Technology Innovation and Regional Ecological Welfare Performance Under Environmental Decentralization

文章基于中国29个省份2005—2018年省级面板数据,采用均方差权值法和比值法对地区科技创新能力和生态福利绩效进行测算,利用空间杜宾模型对环境分权下科技创新与地区生态福利绩效的关系进行实证检验。研究发现:东部大部分地区科技创新能力和生态福利绩效高于中西部地区;科技创新能显著提升地区生态福利绩效,环境分权负向调节科技创新对地区生态福利绩效的正向推动作用;环境分权对科技创新推动地区生态福利绩效的调节作用存在空间异质性和门槛效应。据此,应合理引导地方政府偏好,把握适度的环境分权水平,优化环境支出和科技支出结构,完善地区科技创新体系,进而提升地区生态福利绩效。

Based on the provincial panel data of 29 provinces in China from 2005 to 2018,this paper uses the mean square deviation weight method and ratio method to measure the regional scientific and technological innovation capacity and ecological welfare performance,and uses the spatial Durbin model to empirically test the relationship between scientific and technological innovation and regional ecological welfare performance under environmental decentralization.It is found that the scientific and technological innovation ability and ecological welfare performance of most eastern regions are higher than those of central and western regions;scientific and technological innovation can significantly improve regional ecological welfare performance,environmental decentralization negatively regulates the positive role of scientific and technological innovation on regional ecological welfare performance;the regulatory effect of environmental decentralization on the performance of regional ecological welfare promoted by scientific and technological innovation has spatial heterogeneity and threshold effect.Therefore,we should reasonably guide the preference of local governments,grasp the appropriate level of environmental decentralization,optimize the structure of environmental expenditure and science and technology expenditure,improve the regional science and technology innovation system,and then improve the performance of regional ecological welfare.
