城市群在区域经济社会发展中的作用越来越重要。阐述了产业簇群理论、层域理论、空间相互作用理论和生态学理论等城市群空间结构优化依据。深入分析了特色产业簇群视角的城市群空间结构演变过程。构建了全球、国家和区域等不同尺度的廊道组团网络化城市群空间结构优化模式。最后,作者提出了思想观念创新、市场一体化建设、城乡统筹协调发展、特色产业簇群培育等城市群空间结构优化路径等。

The role of urban agglomeration is becoming increasingly vital in the process of regional economic and social development. Firstly, this paper expounds the basis of spatial structure optimization, like industry cluster theory, layer domain theory, spatial interaction theory and ecological theory; and analyses intensively the evolution of spatial structure from the aspect of characteristic industrial cluster, involving the phase of development of a single company from the corporation level, the phase of characteristic industrial cluster from the small towns level, the phase of characteristic industrial cluster in urban areas from the urban level and the phase of characteristic industrial cluster in urban agglomerations from the urban agglomerations level, evolving from splattering spatial pattern to the mode of corridor group network which has fully utilized comparative advantages of urban areas and has the principal part of characteristic industrial cluster in urban agglomerations. Secondly, the authors construct optimized patterns of spatial structure in urban agglomerations which have the corridor group network mode on a regional, a national and a global scale. Due to distinctions of time and space as well as the development of the characteristic industrial cluster in urban agglomerations, patterns of the optimization of spatial structure in urban agglomerations on regional scale can be divided into the zonal, radial and concentric corridor group network modes. Finally, the paths of spatial structure optimization is put forward in urban agglomerations region, including innovative ideas and concepts, market integration, urban and rural coordination development, characteristic industry cluster nurture. Therefore, the timely linkage collaboration of urban agglomerations region need to be built up to eliminate administrative economic constraint, speed lane construction between different cities in urban agglomeration region, and accelerate free flow of production factors like human resource, material, financial,energy and ecological flow.
