摘　　要：集聚与分化是经济地理学研究的基本过程和核心问题。利用区域条件指数、城市指数、变异系数对辽宁城市核心要素的集聚与分化进行动态分析与比较。结果表明:辽宁城市人口、经济、社会与交通要素呈现出由沈阳经济区向沿海经济带集聚的态势,仅通讯要素呈现出反向发展特征;综合型城市人口、经济、社会要素集聚趋势显著,重工业型城市出现整体分化,轻工业型城市交通、资源型城市通讯要素出现明显集聚;辽宁城市人口、经济、文化层面处于低首位分布状态,沈阳中心性不够明显,但在教育从业、医疗、客货运及邮电等方面垄断能力趋于增强;辽宁省绝对差异呈扩大趋势,经济扩大趋势明显,人口扩大趋势较弱,各城市发展速度差距悬殊,相对差距较大。Agglomeration and differentiation were the basic process and essential question in economic geogra-phy. Regional condition index, city index and the coefficient of variation were used to analyze and compare the ag-glomeration and differentiation of urban core elements in Liaoning Province. Indicators such as population, economy, society and transportation present the agglomeration tendency from Shenyang Economic Zone to Coastal Economic Belt. Telecommunication elements show the characteristics of reverse development. The agglomeration trends are sig-nificant in population, economy and society factors in comprehensive cities. The heavy industry cities present overall differentiation trends. Light industry cities and resources-based cities appear obvious agglomeration in transportation and telecommunication. Population, economy and culture belong to typical distribution of low priority in Liaoning Province.The centrality of Shenyang is not obvious. But in education employment, medical treatment, passenger and goods transport, posts and telecommunications, its monopoly power tends to strengthen. The absolute difference of Li-aoning Province presents the expanding trend. The expanding trend of economy is obvious, but the expanding trend of population is weaker. The urban development speed is wide disparity, and its relative difference is larger.
