As the digital economy becomes new engine of economic growth, China has introduced a series smart city policies aimed at promoting high-quality and sustainable urban development. This paper aims to evaluate green development effects China’s “Smart City Pilot” policy explore heterogeneity across different types cities. Using panel data from 283 prefecture-level cities in 2006 2020, this study examines relationship between construction efficiency using total factor productivity (GTFP). We employ Causal Forest mediation effect models estimate impact pilot on GTFP underlying mechanisms. The main results are: (1) significantly enhances GTFP, finding consistent diverse evaluation approaches. (2) influence varies among cities, such is effectively captured by Forest. (3) varied primarily stems location factors inherent characteristics. Notably, Eastern outpaces that other regions. yields greater benefits with financial medical capital rises, but excessive government public expenditure curtails its positive influence. (4) mechanisms through which promotes exhibit certain differences “high-effect group” “low-effect group”. former predominantly leverages innovation-driven agglomeration effects, while latter chiefly relies industrial structural advancement rationalization.

Impact of digitization on carbon productivity: an empirical analysis of 136 countries

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: March 1, 2024

Abstract Enhancing carbon productivity (CP) is key to achieving reduction goals while maintaining economic growth. Digital technology plays a significant role in improving CP. Based on panel data from 136 countries worldwide 2000 2020, this study empirically examines the impact of digitalization CP and its mechanisms using fixed-effects mediation models. The conclusions are as follows: (1) Overall, significantly enhances (2) In terms mechanism, primarily improves through technological innovation mitigating income inequality. (3) quantile regression results, level increases, promoting effect gradually strengthens. (4) From perspective heterogeneity among regions, levels human capital levels, has greatest promotion European countries, high-income high countries. This provides reference for policymakers use digital emission targets.
