The entropy method was used to calculate the level of digital infrastructure construction, and a time autoregressive model was used. An empirical analysis was used to test the direct impact of digital infrastructure construction on carbon emission intensity, and to further explore whether there is a spatial spillover effect of digital infrastructure construction on carbon emission intensity. The research results show that: ① There is a high degree of spatial correlation in carbon emission intensity in China. ② The construction of digital infrastructure has a significant negative inhibitory effect on carbon emission intensity, and this conclusion remains valid after a series of robustness tests. ③ The construction of digital infrastructure has a significant spatial spillover effect on carbon emission intensity.展开更多

This paper analyzes the current situation of China’s digital infrastructure construction from two aspects: digital infrastructure construction and digital infrastructure application, and finds that China’s digital infrastructure construction and application are in the stage of improvement. On this basis, this paper puts forward the practical challenges that China’s digital infrastructure construction may face. Finally, in order to accelerate the digitalization process in China, the following useful suggestions are provided for the construction of digital infrastructure in China: 1) Increasing supply to ensure sufficient capital investment;2) Formulating investment priorities according to time and place, and bridging the regional “gap”;3) Accelerating the implementation and application of digital infrastructure construction;4) Improving the data guarantee system.展开更多
