摘　　要：城市群结构优化的演变过程是推动城市群发育不断走向成熟与完善的过程。辽宁沿海城市带是我国城市群结构体系中的一个新兴城市群,在我国沿海开发与东北老工业基地振兴中起着战略支点作用。在辽宁沿海经济带开发上升为国家战略的背景下,深入分析该区域城市群的结构特征及优化途径对于整个区域功能提升与发展振兴具有重要意义。本文从人口规模结构、职能结构以及空间结构等方面深入分析辽宁沿海城市带的发展现状特征,并且揭示其中存在的一些问题和不足。在此基础上,从增强大中城市人口集聚规模、重塑都市圈功能关系以及强化轴线式空间拓展等方面提出辽宁沿海城市带的结构优化途径。The structural optimization of urban agglomeration is a process which can promote the development of urban agglomeration towards maturity. Liaoning coastal urban agglomeration which lies in the Bohai bay is the Northeast region＇s only access to the sea. In recent years it has been a highlight in the structure system of Chinese urban agglomeration. Owing to superior location and development foundation, Liaoning coastal urban agglomeration has become the core region to promote the coastal development and revitalize the traditional industrial base of Northeast China. So it is necessary to analyze what the regional structural characteristics are and how the structures get to optimization. This paper discusses the current characteristics of Liaoning coastal urban agglomeration from urban scale ranking, functional and spatial structure. The conclusions are as follows. Firstly, the urban system is characterized by high urban primacy ratio and the gap between different scales is evident. The number and scale of medium-sized cities are all lower than the small cities of which the number is great, but the spatial distributions are imbalanced. Secondly, the industry is in dominant position in the inter-regional labor division, but the productive services have limited influence on regional development. And the intra-regional industrial structure has great homogeneity while the service, transportation, commercial trade complement each other. Thirdly, the transportation network is maturing and its system is forming. The point-axle spatial structure has been formed and developed towards network structure. On the basis of analysis, the authors put forward some suggestions of structural optimization which are that （1） a rational urban system with the mega cities, big cities and the medium-sized cities should be established as the main of the scale structure; （2） based on the remodeling patterns of new regional labor division, the functions of urban zone should be optimized by coordinating spatial organizations, includin
