Abstract: Abstract The integrated construction of a “digital China” and a “beautiful China” is a major task and a strategic initiative to open up new horizons of modernization. Based on panel data spanning from 2011 to 2021, encompassing 284 prefecture-level and above cities in China, this study employs multi-period Difference-in-Differences (DID) and spatial DID models. These models are constructed following theoretical analyses of the intrinsic mechanisms influencing the ecological efficiency of new infrastructures. Additionally, quasi-natural experiments are conducted based on the policy implementations in the demonstration city of “Broadband China”. The study systematically investigates the impact of new infrastructures on China’s eco-efficiency and elucidates their role within the mechanism. The study found that: new infrastructure construction has a significant effect on eco-efficiency, and this conclusion passed a sequence of robustness test; mechanism analysis shows that new infrastructure construction improves eco-efficiency through improving human capital level; heterogeneity analysis shows that new infrastructure has a more obvious effect on ecological efficiency improvement in eastern and resource cities; and the results of the analysis of the spatial effect show that new infrastructure not only improves eco-efficiency in the pilot cities, but also significantly improves ecological efficiency in the pilot neighboring cities.
