The Impact of the Integration of the Digital Economy and Real Economy on Carbon Emission Intensity:Theoretical Models and Empirical Evidence
The integration of the digital economy and the real economy drives technological innovation and Industrial structural upgrading,becoming a new driving force to support low-carbon development goals.By constructing a theoretical model,this research decomposes the effects of integrating the digital economy and the real economy on carbon emission intensity into technological effects and structural effects.Using panel data from 286 cities in China from 2011 to 2021,this research uses the entropy method to measure the comprehensive development of the digital economy and real economy,uses a coupling evalua-tion model to quantify the degree of digital-real economy integration,and then examines the impact of this integration on carbon emission intensity and its underlying mechanisms by employing a two-way fixed effects model.The results show that the integration of the digital economy and the real economy significant-ly reduces carbon emission intensity,and this conclusion still holds after a series of robustness checks.Mechanism analysis reveals that this integration stimulates technological innovation,including green tech-nologies,and improves the upgrading of industrial structure,thereby reducing carbon emission intensity.Additionally,cities with stronger environmental regulations and resource-based cities can obtain greater carbon emission reduction benefits from the integration.These findings provide empirical facts and policy guidance to promote digital-real economy integration and explore new paths for modern low-carbon trans-formation.
