Radiation effect or siphon effect? Coupled coordination and spatial effects of digital economy and green manufacturing efficiency-Evidence from spatial Durbin modelling.

Abstract

This study uses the non-expected SBM-DEM model of factor input-output to measure the green manufacturing efficiency of 274 cities at prefecture level and above in China. The relationship between digital economy and green manufacturing efficiency is analysed on this basis. It is found that the current coupling coordination between digital economy and green manufacturing efficiency is low overall, and there are obvious regional differences. And the digital economy has a significant positive impact on the green manufacturing efficiency of the region and the neighbouring regions, so the digital economy has a radiation effect on the green manufacturing efficiency. Among them, industrial agglomeration plays part of the mediating effect. Based on this conclusion, the following policy recommendations are proposed: first, accelerate the development of the digital economy to stimulate the new kinetic energy of urban green development. Second, implement differentiated development strategies, focusing on the leading role of green advanced cities. Third, deepen the convergence of industries and smooth the channels for green urban development.
