环境规制、创新数量和创新质量——基于空间杜宾模型的实证研究

Environmental Regulation,Innovation Quantity and Innovation Quality:Empirical Research Based on Spatial Durbin Model

采用2009—2019年高技术产业数据,结合莫兰指数,并构建空间杜宾模型实证检验了环境规制对创新数量和创新质量的本地效应和空间外溢效应.结果表明:创新数量存在明显的空间自相关性,且相关性在逐年上升,但创新质量不存在空间相关性;创新数量的集聚区域集中在东部沿海地区,创新质量不存在集聚特征;本地效应显示,环境规制对创新数量和创新质量均呈现促进作用;空间外溢效应显示,环境规制对邻近省份的创新数量具有促进作用,但对邻近省份创新质量的影响微弱.研究结论对于政府制定环境政策,提高我国的创新水平具有重要的意义.

Based on the data of high-tech industry from 2009 to 2019 and Moran index,this paper constructs a spatial Durbin model to test the local and spatial spillover effects of environmental regulation on innovation quantity and quality.The results show that the quantity of innovation has obvious spatial autocorrelation,and the correlation is increasing year by year,while the quality of innovation has no spatial correlation.The quantity of innovation concentrates in the eastern coastal areas,and the quality of innovation does not have the characteristics of agglomeration.The local effect shows that environmental regulation promotes both the quantity and quality of innovation.The spatial spillover effect shows that environmental regulation promotes the quantity of innovation in neighboring provinces,but has a weak impact on the quality of innovation in neighboring provinces.The conclusion is of great significance for the government to formulate environmental policies and improve the innovation level of our country.
