【摘要】：运用熵值法测度了泛长三角地区城市的经济、社会及环境效益,并通过变异系数、探索性空间数据分析法(ESDA)分析了三大效益的差异变动及空间格局演化特征。结果显示:经济效益在整体上不断提升,且城市间发展逐渐均衡;环境效益在整体上不断降低,且城市间的差距逐渐拉大;社会效益在整体上先降后升,且区域之间的差距逐渐缩小;经济效益、社会效益呈显著的空间相似性集聚特征,而环境效益自2006年起逐渐呈现出显著的空间分散分布特征;经济效益高值区的空间分布格局呈"箭头"形、小"Z"形、大"Z"形,且逐渐由单中心极化发展向多中心均衡化发展的格局转变;社会效益的集聚格局大致与经济效益相似,而环境效益的"破碎化"分布格局逐渐显现。
[Abstract]:The economic, social and environmental benefits of cities in the pan-Yangtze River Delta region are measured by the entropy method, and the coefficient of variation is adopted. The exploratory spatial data analysis (ESDAA) analyzes the variation of the three benefits and the evolution characteristics of spatial pattern. The results show that the economic benefits are improving continuously and the development of cities is gradually balanced; As a whole, the environmental benefit is decreasing, and the gap between cities is widening gradually. As a whole, the social benefits first decreased and then increased, and the gap between regions gradually narrowed; The economic benefits and social benefits showed significant spatial similarity agglomeration characteristics, while the environmental benefits gradually showed significant spatial dispersion since 2006. The spatial distribution pattern of the high value area of economic benefit is arrowhead, small Z and big Z, and the pattern of development from single center polarization to multi center equalization is gradually changed. The agglomeration pattern of social benefit is similar to that of economic benefit, while the "fragmentation" distribution pattern of environmental benefit appears gradually.
