武汉城市圈产业发展的空间优化

武汉城市圈是指以武汉市为中心，包括黄石、鄂州、黄冈、孝感、咸宁、仙桃、潜江和天门等周边8市共同组成的城市密集区。该区域具有悠久的产业发展传统，其历史轨迹可分为3个阶段：第一阶段（1840~1949）为产业发展起步时期，第二阶段（1949~1994）为产业结构强化时期，第三阶段（1994~）为产业体系调整时期；与此相适应，区域产业的部门结构和空间结构均呈现典型的集中特征，以2003年区域制造业的增加值为指标，武汉市的空间集中度为50.5％,前10类制造业的产业集中度为60.6％。据此，目前的武汉城市圈是一个松散的“经济联邦”，但存在区域整合的产业、空间和创新基础。以2001~2004年武汉城市圈9城市的统计资料为基础，以制造业分行业的年均增加值和增长率为指标，计算和分析其区域产业发展潜力，结果表明：以钢铁、汽车和电子及通讯设备制造业等为依托，构建区域集群网络，能够充分发挥武汉市的产业组织和创新扩散功能。武汉城市圈应进一步调整产业发展思路，坚持创新驱动路径，通过完善集群网络规划、强化区域空间关联和引导产业集聚发展等政策措施，有效推动具有区域竞争优势的特色产业发展。

ON SPATIAL OPTIMIZATION OF INDUSTRIAL DEVELOPMENT IN WUHAN URBAN CLUSTER

Wuhan urban cluster is a city compact region with Wuhan as the center.The long history of industrial development of Wuhan can be divided into three periods：the first period (1840~1949) is the beginning stage，the second one (1949~1994) refers to that of industrial structure strengthening，and the last one (1994~) is that of the industry system adjustment.Correspondingly，the sectional structure and the spatial structure of the regional industry appear to be typically centralized.Taking the added value of the regional manufacture in 2003 as the target，the degree of the spatial configuration of Wuhan City is 50.5％，and the degree of industrial configuration of the top ten manufacturing is 60.6％.According to this，though an incompact economic federation nowadays，it has some foundations to integrate the industries，space and innovation.Based on the statistical data from 2001~2004 of the 9 cities in Wuhan cluster，with indicators of annual average value added and increment rate of manufacturing by industrial sector，and by means of calculating and analyzing its region industrial potential ability to develop，it is concluded that we can promote the development of special sectors with regional competitiveness through constructing industrial cluster networks based on iron and steel industry，automobile industry，and electric & communication equipment manufacturing，which can make full use of industrial organization and expand function of innovation in Wuhan City.It is necessary to promote effectively the development of special sectors with regional competitiveness by taking relative policies and measures such as consummating the cluster networks programming，strengthening the region space connection and leading the development of industrial convergenceetc.
