Study on Effects of Compact Urban Spatial Development on Carbon Performance:A Case Study of 41 Cities in the Yangtze River Delta
Based on the morphological,structural,and functional dimensions,as well as the economic and social welfare output per unit of carbon emission,the paper measured the compactness and carbon performance of 41 cities in the Yangtze River Delta,and studied the spatial and temporal correlation between the two respectively,as well as used spatial econometric methods to analyze the three sub-indicators of compactness,connectivity,prox-imity,and functional mix,on carbon performance.The results show that:(1)Regional urban compactness is in-creasing in the Yangtze River Delta from 2012 to 2020,but the distribution varies obviously,the overall spatial pat-tern of carbon performance is"high in the central-east and low in the north-west".(2)Compactness and carbon performance both have certain spatial correlation characteristics,and the proportion of cities in the localized high-high agglomeration and low-low agglomeration areas of the two are highly coincident.The aggregation of highly com-pact cities will bring about the aggregation of cities with high carbon performance in the same area.(3)Connectivi-ty,proximity,and functional mix significantly promote the carbon performance of this city and its neighboring cit-ies,with connectivity having the greatest impact on the carbon performance of this city and proximity the lowest;and proximity having the greatest impact on carbon performance of its neighboring cities,and connectivity the low-est.
