低碳城市试点政策的产业碳减排效应再评估:来自38个二位数工业行业的新证据
Re-Evaluating the Industrial Carbon Emission Reduction Effects of Low-Carbon City Pilots:New Evidence from 38 Two-Digit Industrial Sectors
摘要
Abstract
Based on carbon emission data from 38 two-digit industrial sectors across 133 cities from 2009 to 2020,this study reappraises the carbon reduction effects of low-carbon city pilot policies using a difference-in-differences approach and explores potential mechanisms through resource allocation and technological innovation.The results indicate that low-carbon pilot policies significantly reduce carbon intensity at the city-sector level.Optimized land resource allocation serves as an important channel for the policy's impact,while the level of technological innovation also plays a critical role in the emission reduction process.The carbon reduction effect is more pronounced in cities with greater fiscal pressure or lower dependence on land finance,as well as in medium-low technology,labor-intensive,and capital-intensive sectors.The policy exhibits a stronger emission reduction effect in high-carbon industries.This study helps to unveil the implementation mechanism of low-carbon policies at the city-sector level and provides theoretical insights for exploring localized low-carbon development pathways.关键词
