摘　　要：从泛长三角省域、市域和市区三个层面,通过构建加权空间平衡点模型、中心度指数模型以及运用绝对集中度、分散度指数和城市场理论分析其空间格局演变过程。研究发现,泛长三角省域空间平衡点有趋近地理重心的态势;泛长三角地级市经济空间上主要呈现以沪宁线为核心的中心—边缘结构特征,市域经济出现空间极化和离散现象,空间上基本表现为GDP前十位城市和后十位城市,并找出了各个城市在不同时期其经济发展对整个区域空间格局的影响作用;泛长三角经济呈现由较均衡到趋不平衡再到趋均衡的发展态势。The generalization of the Pan Yangtze River Delta has become inevitable because of economy development and its facing problems in the Yangtze River Delta. Researching evolution of economy space structure the Pan Yangtze River Delta can help us appreciate and grasp its trends of space evolution, and to provide the basic data for regional integration of the Pan Yangtze River Delta. The author analyzes evolution process of the Pan Yangtze River Delta Depending on constructing the models of Weight Space Equilibrium Points and Centre Indexes, Absolute Concentration,Absolute Dispersion and Diffusion Theory. The research shows that space equilibrium points of province region in the Pan Yangtze River Delta are approaching toward geography weight; Economy Space of the Pan Yangtze River Delta forms Core-edge structure for Hu-Ning Railway-centred; economy structure of level city region forms space polarization and separation and they are credited with first ten cities and last ten cities, and further research finds out that economy development of every cities effect on space structure in every period; economy development of it evolved from relative balance to unbalance, relative balance using diffusion method of the town economy.
