摘　　要：基于形态、结构和功能维度以及单位碳排放经济、社会福利产出视角,测算长三角41个城市紧凑度及碳绩效综合指数,并分析二者的空间自相关性。运用空间计量方法分析连接度、邻近度及功能混合度3个紧凑度分指标对碳绩效的影响效应。结果表明:(1)2012—2020年长三角城市紧凑化程度整体呈上升趋势,但分布差异明显;碳绩效总体呈现“中东部高、西北部低”的空间格局。(2)紧凑度和碳绩效均具有一定的空间关联特征,且二者局部高-高集聚及低-低集聚区中城市占比均高度吻合,高紧凑度城市的集聚会带来同区城高碳绩效城市的聚集。(3)连接度、邻近度及功能混合度均显著促进城市碳绩效的提高;对当地城市碳绩效影响效应中,连接度影响程度最大,邻近度影响程度最低;对周边城市碳绩效影响效应中,邻近度影响程度最大,连接度影响程度最小。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,proximity,and functional mix,on carbon performance.The results show that:(1)Regional urban compactness is increasing in the Yangtze River Delta from 2012 to 2020,but the distribution varies obviously,the overall spatial pattern 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 compact cities will bring about the aggregation of cities with high carbon performance in the same area.(3)Connectivity,proximity,and functional mix significantly promote the carbon performance of this city and its neighboring cities,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 lowest.
