产业结构演进与城镇空间结构的对应关系和影响要素

对城镇密集区而言，经济发展方式的转变和产业结构升级必需要有合理和有序的城镇空间组织模式作为支撑。本文以长三角为研究地区，对产业结构演进与城镇空间结构的对应关系和影响要素进行了探讨。据此认为，基于城市功能定位和合理分工基础之上的高度现代化的两大网络（基础设施网络、市场体系和产业组织网络）是推进产业结构不断演进和升级的重要条件．也是推动城镇空间结构和组织模式持续优化的着力点和主要抓手：促进产业结构演进与城镇空间结构对应的影响要素主要包括：首位城市的发达程度、城市间合理和有序的层级关系、城市体系网络的现代化程度。相对而言，长三角第二和第三要素的矛盾都比较突出．是当前促进产业结构演进与城镇空间结构对应和加强产业结构升级与城镇组织模式协同的关键所在．

Relationship and Influence Factors between Change of the Industrial and Urban and Township Spatial Structures of the Yangtze Delta Area

To an area concentrated with cities and ic growth and upgrade of industrial structure need urban and township spatial structure as to back up towns, change of the mode of economa rational and orderly pattern of the Through detailed analysis of the concept and nature of the ＂megalopolis＂, this paper discusses the relationship and influence factors between change of the industrial and urban and township spatial structures of the Yangtze Delta Area and argues that： i） the two highly modernized networks （infrastructure networks and the market and industrial organization networks） based on functional division of labor between individual cities possess crucial importance in facilitating change and up- grade of the industrial structure on one side and sustained optimization of the organizational pattern of the urban and township spatial structure on the other; ii） in the light of the Yangtze Delta Area, influence factors in promoting positive corresponding states between change of the industrial structure and urban and township spatial structure are concerned with development level of the first place city, rational and orderly hierarchy of the urban and township system and, meanwhile, up-to-dateness of the city networks. Relatively, the second and third factors mentioned above are among the most important and the keys in strengthening interlocking between facilitating change and upgrade of the industrial structure and promoting optimization of the pattern of the urban and township spatial structure.
