摘　　要：城市空间绩效评价能够揭示城市空间发展的效率和均衡性问题,为城市空间发展预警,提高政府制定城市发展战略的能力。在阐释城市空间绩效内涵的基础上,从“经济—社会—环境”视角构建空间绩效评价体系,运用熵值法—层次分析复合模型、耦合协调度模型等,对长三角地区26个中心城市的空间绩效与系统协调性演变特征进行系统研究。结果表明:(1)城市空间综合绩效处于加速提升阶段,3大子系统内部结构存在明显演变,综合绩效正从效率优先向社会服务均衡优先转变。(2)城市空间“经济—社会—环境”系统协调度总体程度仍然较低,但两两耦合协调水平发现3大系统均处于正向协调优化阶段,且“经济—社会”协调度演进速度较高。(3)城市空间绩效系统协调性基本遵循从低度协调到中度协调的演化路径,各类问题城市存在空间集聚的态势。Urban spatial performance evaluation can reveal the efficiency and balance of urban development,provide early warning for urban spatial development,and improve the government's ability to formulate urban development strategies.On the basis of elucidating the connotation of urban spatial performance,the paper constructs a spatial performance evaluation system from the perspective of"economy-society-environment",and uses the entropy method-analytic hierarchy process composite model and coupling coordination degree model to systematically study the spatial performance and system coordination evolution characteristics of 26 central cities in the Yangtze River Delta region.The results show that:(1)The comprehensive performance of urban space is in the stage of accelerating improvement.The internal structure of the three subsystems has obviously evolved,and the comprehensive performance is changing from efficiency priority to social service balance priority.(2)The overall degree of coordination of the economic performance,social performance and environmental performance of urban space is still low,but the level of coupling and coordination of the two shows that the three subsystems are in the positive coordination and optimization stage,and the evolution speed of the coordination of economic performance and social performance is high.(3)The coordination of urban spatial performance system basically follows the evolutionary path from low coordination to medium coordination,and all kinds of problem cities have the trend of spatial agglomeration.
