Mechanism and Spatial Spillover Effect of New-Type Urbanization on Urban CO2 Emissions: Evidence from 250 Cities in China

Exploring the effect of new-type urbanization (NTU) on urban carbon abatement is great practical significance for promoting green construction and coping with challenge global climate change. This study used data from 250 cities in China 2008 to 2020 constructed NTU evaluation indicator system five dimensions. We classical panel regression models examine effects CO2 emissions, further spatial econometric SEM, SAR, SDM identify spillover emissions. The main results are that China’s emissions generally rising, has a significantly negative an impact coefficient −0.9339; conclusions still hold after subsequent robustness tests. Heterogeneity analysis reveals NTU’s more pronounced resource-based cities, old industrial areas, lower levels higher innovation levels. Mechanism shows improving technological optimizing resource allocation important paths realizing emission reduction. noticeable spillover. Our findings provide policy makers solid support driving high-quality development dual-carbon targets.
