Pilot policies for low-carbon cities in China: a study of the impact on green finance development and energy carbon efficiency

Abstract

ABSTRACT Improving the efficiency of energy carbon emissions (ECEE) is crucial for China's pursuit of high-quality development. This paper assesses the low-carbon city pilot policy (LCCPP) as a strategic measure to enhance ECEE and its alignment with global efforts to mitigate climate change. By analyzing panel data from 205 Chinese cities from 2003 to 2016, this study evaluates the LCCPP's effectiveness and its spatial spillover effects on ECEE. Results indicate a 6.5% increase in ECEE in pilot cities compared to non-pilot counterparts, with these findings substantiated through extensive robustness checks. The analysis of underlying mechanisms reveals that the LCCPP boosts ECEE by promoting green finance and the co-agglomeration of producer services and manufacturing. Furthermore, the policy's impact varies: it is more substantial in non-resource-based cities and in those with advanced green finance and synergistic industry agglomerations. Employing a spatial difference-in-differences approach, the study uncovers an inverted U-shaped pattern in the spillover effects of the LCCPP on ECEE, suggesting a nuanced regional influence of the policy. This research contributes to the understanding of policy-driven environmental improvements and their economic co-benefits within urban settings.
