城市全域数字化转型对绿色全要素生产率的影响效应
The Impact of City-Wide Digital Transformation on Green Total Factor Productivity
摘要
Abstract
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.关键词
