Impact of digital infrastructure on urban green eco-efficiency: an empirical analysis in China

Abstract

Purpose

This paper takes 267 prefecture-level cities that have implemented the “Broadband China” strategy as empirical research objects, aiming to study the impact of digital infrastructure on the green eco-efficiency of Chinese cities and put forward corresponding policy recommendations based on the empirical results.

Design/methodology/approach

By integrating the super-efficiency Undesirable-SBM model with the asymptotic difference-in-differences approach, the research delves into the policy impacts and the mechanisms by which digital infrastructure affects urban green eco-efficiency.

Findings

The results reveal a notable influence of advancements in digital infrastructure on the eco-efficiency of urban areas, and these advancements have the capacity to bolster eco-efficiency through the influence of green technological innovation, the upgrading of industrial structure, and its rationalization. Notably, significant variations are found in the effectiveness of digital infrastructure in boosting eco-efficiency, with the effect being relatively stronger for large-scale cities and eastern regions.

Originality/value

From a research standpoint, this paper seeks breakthroughs in harmonizing ecological environments with economic quality in the digital era’s new paradigms. Methodologically, it avoids the incomparability of traditional measurements, ensuring accurate urban ecological efficiency assessments. Content-wise, it elucidates how the digital economy enhances eco-efficiency through green technological innovation, industrial structure advancement and rationalization. This comprehensive analysis provides valuable insights for China and similar developing nations on balancing green ecological efficiency with urban digitization, offering practical guidance for sustainable development.
