【摘要】：基于城市职能的专业化部门、职能规模和职能强度三要素,利用全国第五次和第六次人口普查数据,分析了2000-2010年长江经济带城市职能结构与演变特征。结果显示:1工业、建筑业、商业、房地产、科研和其他服务业部门是长江经济带的基本职能部门;2长三角地区是长江经济带的工业重心,城市群和大城市的工业化进程显著,产业梯度转移已经取得显著效果,但尚缺少国家层面分区分级的调控引导机制,生态环境安全面临巨大压力;3建筑和房地产业职能正在由下游向上中游转移,并拉动包括商业、科研、金融、社会服务、其他服务业等生产性和生活性服务业的迅猛发展,但城市产业同构现象严重,中心城市集聚能力不足;4交通通信业职能下降,难以支撑长江经济带国家战略的顺利实施。针对以上特征与问题,建议以管理机制创新培育流域一体化城市(群)职能分工体系,以流域产业准入标准保障协同发展的绿色城市职能体系,以城市群战略和国家级新区链接城市职能互协互补网络体系,以长江经济带综合立体交通走廊优化沿江城市资源配置格局。
[Abstract]:Based on the three elements of specialized department, function scale and function intensity of urban functions, and using the data of the fifth and sixth national population censuses, this paper analyzes the functional structure and evolution characteristics of cities in the Yangtze Economic Belt from 2000 to 2010. The results show that the industrial, construction, commercial, real estate, scientific research and other service sectors of the Yangtze River Economic Belt are the basic functional departments of the Yangtze River Economic Belt. The Yangtze River Delta region is the industrial center of the Yangtze River Economic Belt, and the industrialization process of the urban agglomerations and big cities is remarkable. Although the industrial gradient transfer has achieved remarkable results, there is still a lack of regulation and guidance mechanism at the national level, and the ecological environment security is under great pressure. The functions of building and real estate are shifting from downstream to upper-middle reaches, and the functions of construction and real estate industry are moving from downstream to mid-stream, which includes commerce. Scientific research, finance, social services, other services and other producer and living services have developed rapidly, but the phenomenon of urban industry isomorphism is serious, and the central cities have insufficient agglomeration capacity. It is difficult to support the smooth implementation of the national strategy of the Yangtze economic belt. In view of the above characteristics and problems, it is suggested that the function division system of integrated watershed cities (groups) should be cultivated through management mechanism innovation, and the green city function system of coordinated development should be guaranteed by watershed industry admission standards. Based on the strategy of urban agglomeration and the network system of linking the functions of cities to each other, the urban resources allocation pattern along the Yangtze River is optimized by the integrated three-dimensional traffic corridor of the Yangtze River economic belt.
