How does the digital economy affect industrial eco-efficiency? Empirical evidence from China

Blog Article

Industry is a sector with large energy consumption and pollutant emissions.Improving industrial eco-efficiency is crucial to energy conservation and pollution reduction.The digital economy has developed rapidly in recent years.

However, there is a lack of research on the specific relationship between the digital economy and industrial eco-efficiency.This study measured the industrial eco-efficiency of 30 provinces in China from 2010 to 2020, through a super-efficiency slack-based measure (SBM) considering desirable outputs.By constructing a two-way fixed effect model and a panel quantile model, this study explored the effects of the digital economy on industrial eco-efficiency on a national scale.

Furthermore, this study conducted grouping regression click here and investigated the heterogeneous impacts of the digital economy on industrial eco-efficiency.Finally, this study built a spatial Durbin model to explore the spatial effects of digital economy on industrial eco-efficiency.According to the empirical results, this study yielded the following conclusions.

First, the digital economy has a significantly positive effect on industrial eco-efficiency at the national scale, with diminishing marginal returns.Second, the effects of the digital economy rumchata proof on industrial eco-efficiency are significantly heterogeneous on a regional scale.For eastern regions, the effects of the digital economy on industrial eco-efficiency are significantly positive, while they are negative for western regions.

Third, the spillover effect of the digital economy on industrial eco-efficiency is not significant in China, indicating that there is digital isolation.
