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 lorenametaute.com 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 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 on industrial eco-efficiency are significantly heterogeneous on a regional scale.For voyage et cie discount code 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.
