Does Urban Renewal Improve Urban Metabolic Efficiency?Evidence from DID and Spatial Durbin Model
Based on the panel data of 280 prefectural-level cities in China from 2004 to 2020,the impact of urban renewal(UR)on urban metabolic efficiency(UME)is examined using the difference in difference(DID)method and spatial Durbin model,using the old neighborhood pilot as a quasi-natural experiment of UR.This study reveals that UR significant-ly and robustly enhances UME.Mechanism analysis shows that UR enhances UME mainly through four paths:catalyzing in-dustrial structure upgrading,promoting green investment,driving consumption upgrading,and improving infrastructure con-struction.The spatial correlation test result indicates that UME has a significant positive spatial correlation.The results of spatial spillover effects demonstrate that UR significantly drives UME enhancement in local and neighboring regions.
