城市全域数字化转型对绿色全要素生产率的影响效应OACHSSCD
The Impact of City-Wide Digital Transformation on Green Total Factor Productivity
以中国284个城市为研究对象,实证检验城市全域数字化转型对绿色全要素生产率的直接影响、传导机制与空间溢出效应.结果表明:城市全域数字化转型能够显著提升绿色全要素生产率,且其影响具有区域异质性.东部、中部与西部地区的城市全域数字化转型显著提升了绿色全要素生产率,但对东北地区的绿色全要素生产率无显著影响.机制分析表明,城市全域数字化转型通过提高城市创新水平,间接提升了绿色全要素生产率.空间计量分析发现,城市全域数字化转型不仅能够提升本地的绿色全要素生产率,而且对邻近城市的绿色全要素生产率产生正向空间溢出效应.由此,政府应持续推进城市全域数字化转型,因地制宜实施差异化政策,加强创新驱动,增进城市间合作与交流,提升区域整体绿色生产力.
This study empirically examines the direct effect,transmission mechanism,and spatial spillo-ver effect of city-wide digital transformation on green total factor productivity(GTFP)using data from 284 Chinese cities.The results indicate that city-wide digital transformation can significantly en-hance GTFP,with this impact exhibiting regional heterogeneity.Specifically,city-wide digital transfor-mation significantly improves GTFP in eastern,central,and western regions of China,but shows no significant effect in the northeastern region.Mechanism analysis reveals that city-wide digital transfor-mation indirectly boosts GTFP by stimulating urban innovation levels.Spatial econometric analysis further demonstrates that city-wide digital transformation not only enhances local GTFP but also gen-erates positive spatial spillover effects onGTFP in neighboring cities.Accordingly,governments should persistently advance city-wide digital transformation,implement differentiated policies tailored to local conditions,strengthen innovation-driven development,promote inter-city cooperation and exchange,and ultimately enhance regional green productivity as a whole.
