A study of industrial structure, government attention, and coupling coordination of digital-green economy in China

The goal of this paper is to investigate the coupling coordination relationship between the digital economy and the green economy, as well as to analyze possible ways to improve the coupling coordination degree. By using panel data for 280 cities from 2011 to 2018, this study has made outstanding contributions in the following areas: (1) reintegrating and constructing the evaluation index system of the digital economy and green economy; (2) utilizing the modified coupled coordination degree model to analyze it; (3) adopting the fixed effect model to test the influencing factors. The findings revealed that the current level of coupling coordination between the digital economy and the green economy in China is generally low, with significant regional differences. In terms of influencing factors, industrial structure upgrading has a U-shaped influence on coupling coordination, and government attention has an inverted U-shaped influence on coupling coordination.
