Abstract
This article constructs the entropy method to construct a more comprehensive digital economy indicator system, combines the two-way panel threshold model, intermediary effect model, and threshold effect model to explore the mechanism of digital economy enabling manufacturing industry carbon reduction in 192 prefecture-level cities in China. First, digital economy has effectively enabled manufacturing industry’ carbon emission reduction by enhancing energy efficiency and promoting industrial structure upgrading. Second, the enabling effect will vary according to regional heterogeneity and different industrial development scales. Third, there is a single threshold of institutional environment and industrial scale for digital economy to promote carbon emission reduction.
期刊介绍：
The Bulletin of Economic Research is an international journal publishing articles across the entire field of economics, econometrics and economic history. The Bulletin contains original theoretical, applied and empirical work which makes a substantial contribution to the subject and is of broad interest to economists. We welcome submissions in all fields and, with the Bulletin expanding in new areas, we particularly encourage submissions in the fields of experimental economics, financial econometrics and health economics. In addition to full-length articles the Bulletin publishes refereed shorter articles, notes and comments; authoritative survey articles in all areas of economics and special themed issues.
