摘要
从空间维度厘清了数字经济驱动制造业绿色发展的空间溢出机理,并基于2011—2019年中国地级及以上城市(市域)层面数据,利用空间杜宾模型检验了数字经济驱动制造业绿色发展的空间溢出效应。结果表明:(1)数字经济不仅驱动本地区制造业绿色发展,也通过空间溢出效应促进了周边地区制造业绿色发展。(2)数字经济空间溢出效应与地理区位、人口规模、市场一体化水平等城市特征相关,东南沿海地区城市、人口规模更大城市、市场一体化水平更高城市具有更强的数字经济空间溢出效应。(3)知识产权保护作为促进数字经济发展的重要制度保障,增强了数字经济驱动制造业绿色发展的空间溢出效应。(4)随着地理距离增加,数字经济空间溢出效应存在一定程度衰减的规律。
From the spatial dimension,it clarified the spatial spillover mechanism of the digital economy driving the green development of manufacturing industry,and used the spatial Durbin model to test its spatial spillover effect based on the data of Chinese prefecture-level cities from 2011 to 2019.The results show that:1)Digital economy not only drives the green development of manufacturing industry in this region,but also promotes the green development of manufacturing industry in surrounding areas through the spatial spillover effect.2)The spatial spillover effect of the digital economy is related to urban characteristics such as geographical location,population size and market integration level.Cities which are in the southeast coastal area,with larger population size or with higher market integration level have stronger spatial spillover effect of digital economy.3)As an important institutional guarantee to promote the development of digital economy,intellectual property protection enhances the spatial spillover effect of digital economy driving the green development of manufacturing industry.4)With the increase of geographical distance,the spatial spillover effect of digital economy has a certain attenuation.
