建设数字中国与美丽中国都是新时代实现经济高质量发展的重要途径.基于 2011-2019 年我国 286个地级以上城市的面板数据,利用ArcGIS软件可视化分析方法探讨我国数字经济发展的时空演变特征,并采用空间杜宾模型实证检验数字经济发展对我国雾霾污染的影响.研究发现:我国数字经济发展水平逐渐提升,数字经济发展水平较高的地区主要分布在沿海地带,并且我国数字经济发展水平和雾霾污染均呈现明显的"高—高"集聚和"低—低"集聚的空间关联特征;数字经济发展不仅可以减少本地区的雾霾污染,同时还能改善邻近地区的环境质量,这一结论经过引入工具变量、替换被解释变量、替换空间权重等稳健性检验后依旧成立;异质性分析发现,数字经济发展减少雾霾污染的作用在中部地区和西部地区更明显,而数字经济发展对雾霾污染的外溢作用在东部地区更大,此外,雾霾污染较轻地区数字经济发展对雾霾污染的降低作用和外溢作用较大.因此,加大数字化基础设施建设,强化数字赋能减霾效应,加强高污染、高排放等传统产业的数字化转型,促进区域间技术合作与信息交流,充分发挥数字经济发展对雾霾污染的负向空间溢出效应,对实现经济高质量发展具有现实意义.
Will Digital Economy Reduce Smog Pollution in China?—An Empirical Analysis Based on Spatial Durbin Model
Building a digital China and a beautiful China are both important ways to achieve high-quality economic development in the new era.Based on the panel data of 286 cities above prefecture level in China from 2011 to 2019,and using the the ArcGIS Software visualization analysis method,this paper explores the spatio-temporal evolution characteristics of the development of digital economy,at the same time the paper examines the impact of the digital economy development on smog pollution based on spatial Durbin model.The main findings are as follows:First,digital economy in China is de-veloping to a higher level,and the areas with higher level of development of digital economy are mainly located in the coastal zones,moreover,the de-velopment level of digital economy and smog pollution in our country have obvious spatial correlation characteristics of"high-high"agglomeration and"low-low"agglomeration.Second,the development of the digital economy can not only restrain the smog pollution in the region,but also improve the environmental quality of neighboring regions,this conclusion is still valid after introducing instrumental variables,substituting interpreted variables and substituting spatial weights.Third,the heterogeneity analysis shows that the digital economy development has a more significant inhibitory effect on smog pollution in the central and western regions,however,it has a greater spillover effect on smog pollution in the eastern regions.In addition,in the areas with less smog pollution,the digital economy development has a great effect on the suppression and spillover of smog pollution.Therefore,we need to step up the development of digital infrastructure,strengthen the effectiveness of digital empowerment in reducing smog,strengthen the digital transformation of traditional industries such as high-pollution and high-emission industries,promote interregional technical cooperation and information exchange,and make full use of the negative spatial spillover effect of the digital economy development on smog pollution.All these practices are of practical significance to the realization of high-quality economic development.
