数字经济对制造业绿色转型的空间溢出效应
Spatial spillover effects of the digital economy on the green transformation of the manufacturing industry
摘要
Abstract
The green transformation of the manufacturing industry is an important segment in high-quality development,and the vigor-ous development of the digital economy has provided a new impetus.Taking the balanced panel data of 277 cities in China from 2011 to 2021 as the sample,this study used the super-efficient SBM model containing unexpected output to measure the effects of the green transformation of the manufacturing industry at the city level,measured the digital economy index at the city level based on the entropy weight method,and then used the general nesting spatial model to empirically analyze the impact of the digital economy on the green transformation of the manufacturing industry.After drawing the basic conclusions,this study further applied the mediation effect model and the two-zone spatial econometric model to analyze the mediation and moderation factors of the digital economy on the green transfor-mation of the manufacturing industry.The results indicated that:① The green transformation of manufacturing industry among Chinese cities presented a spatial clustering feature,specifically manifested as the siphon effect,which means that the green transformation of manufacturing industry in a city was not conducive to the green transformation of manufacturing industry in its surrounding cities.② The digital economy not only significantly promoted the green transformation of the manufacturing industry in this city,but also in the surrounding cities.This conclusion remained valid after a series of endogeneity and robustness tests.③ Mediation analysis found that the promotion of the digital economy in the green transformation of the manufacturing industry occurred through three channels:promoting green technology innovation,optimizing resource allocation efficiency,and improving green credit.④ Moderation analysis in-dicated that the relationship between the digital economy and the green transformation of the manufacturing industry was affected by en-ergy efficiency,and lower energy efficiency weakened the role of the digital economy.Compared to existing research,this study im-proves the theoretical mechanism of the digital economy-manufacturing green transformation relationship from the perspectives of re-sources and credit and explores the moderation factors in this relationship from the energy perspective.The spatial econometric model in this study also comprehensively considers the spatial correlation caused by geographical and economic factors,which is progress com-pared to previous studies that only considered geographical spatial correlation.Based on the research results,this study proposes rele-vant implications to accelerate the development of the digital economy,improve energy efficiency,accelerate green technology innova-tion,improve resource allocation efficiency,and optimize green credit.关键词
