长江中游城市群区域一体化的测度与比较

实现长江中游城市集群区域一体化,既能承接东部地区产业转移，也能够向西部传递发展势能,缩小西部与中东部的差距。参照了世界银行从密度、距离与分割3个维度对区域一体化的界定，构建了区域一体化评价体系；采用2000～2010年数据,并结合层次分析法对长江中游城市集群内部区域一体化进行测度与比较分析。研究显示：（1）长株潭城市圈区域一体化水平最高，武汉城市圈次之，环鄱阳湖生态经济区最低，但三大城市群一体化水平都呈现逐渐增长趋势；（2）三大城市群在市场一体化、行政一体化及社会一体化变化水平差异明显但总体差距逐渐缩小；（3）武汉城市圈在“两型”社会建设推动下一体化水平稳步提升，长株潭城市群一体化水平进程最快，环鄱阳湖生态经济区后发优势明显。在此基础上，提出了构建长江中游城市集群经济发展联动机制的政策建议

REGIONAL INTEGRATION OF THE YANGTZE RIVER MIDDLE REACHES URBAN AGGLOMERATIONS:MEASURING AND COMPARISON

Since the development strategy of central China was carried out，three urban agglomerations as Wuhan City Circle，Changsha Zhuzhou Xiangtan City Cluster and Poyang Lake Ecological Economic Zone have been formed along the middle reaches of the Yangtze River. It is the basic and strategic direction for the Yangtze River Middle Reaches Urban Agglomerations to carry forward the integration process，promote the regional updating of industrial structure and forge the fourth pole of Chinese economic development. Apparently，the accelerating of regional integration of the Yangtze River Middle Reaches Urban Agglomerations is not only beneficial to carry on the competitive industry transferring to promote locative industry development，but also is beneficial to promote the development of the Central Henan Urban Agglomeration and deliver the developing potential energy of eastern areas toward the western areas，thus narrowing the development gap between western areas and eastern ones，which are of great significance. In this paper，we adopted the threes dimensions of density，distance and segmentation to evaluate the regional integration level and built the evaluation systems in reference to the report of “World Development Report 2009: Reshaping Economic Geography” by the World Bank in 2010. In addition，we adopted certain data from 2000 to 2010 and made practical investigation in the respective city cluster areas. What is more，we made analysis of the date through taking advantage of the method of AHP and Standard Deviation to measure the specific integration level of Wuhan City Circle，Changsha Zhuzhou Xiangtan City Cluster and Poyang Lake Ecological Economic Zone，and finally made a comparison. The results were as follows: （1） The integration level of Changsha Zhuzhou Xiangtan City Cluster showed best，Wuhan City Circle followed and the Poyang Lake Ecological Economic Zone was the lowest，and the three urban agglomerations integration levels showed a growing trend. （2） The difference in market integration，administrative integration and social integration were obvious of the three urban agglomerations as Wuhan City Circle，Changsha Zhuzhou Xiangtan City Cluster and Poyang Lake Ecological Economic Zone，however，the difference were narrowing. （3） Wuhan City Circle integration level were improving steadily under the promotion of strategy of “energy saving，environment protective” construction；Changsha Zhuzhou Xiangtan City Cluster showed unique advantage as the earliest experiment site; Poyang Lake Ecological Economic Zone showed obvious later mover advantage. Finally，we tried to sweep away the obstacles of regional integration of the urban clusters，and put forwards certain suggestions to build the linkage mechanism of regional development
