数字经济赋能长三角制造业高质量发展——空间溢出与机制识别

Digital Economy Enables High-qualityDevelopment of Manufacturing Industry in the YangtzeRiver Delta: Spatial Spillover and Mechanism Identification

基于2011—2021年长三角地区41个城市的面板数据,采用主成分分析法和空间杜宾模型等方法实证检验数字经济对长三角制造业高质量发展的赋能效应及多重路径的综合作用效果。结果表明:长三角地区数字经济不仅能显著赋能本地制造业高质量发展,还对邻近地区制造业高质量发展有显著的促进作用,空间溢出效应占比为79.4%;数字经济赋能制造业高质量发展主要依赖于人力资本和物质资本积累,且人力资本与物质资本呈协同效应,消费能力路径与人力资本、物质资本均呈背离效应。

Based on the panel data of 41 cities in the Yangtze River Delta region from 2011 to 2021,this paper adopted principal component analysis and SDM to empiric-test the empowering effect of digital economy on the high-quality development of the manufacturing industry in the Yangtze River Delta and the comprehensive effect of multiple paths.The results show that:The digital economy in the Yangtze River Delta region can not only significantly enable the high-quality development of local manufacturing industry,but also significantly promote the high-quality development of manufacturing industry in neighboring regions,with the spatial spillover effect accounting for 79.4%;The digital economy enables the high-quality development of manufacturing industry mainly depends on the accumulation of human capital and physical capital,and human capital and physical capital have a synergistic effect,and the path of consumption power has a deviation effect from both human capital and physical capital.
