根据城市化的内涵,从人口城市化、经济城市化、生活方式城市化和地域景观城市化等4个方面,构建区域城市化水平的综合评价指标体系,并运用熵值法,对1991~2005年江苏省城市化水平进行综合分析;结果发现江苏省城市化水平在不断提高的同时,主要表现为经济城市化和地域景观城市化的快速发展,而人口城市化对区域城市化的总体贡献不断减弱;在此基础上,结合多元线型回归模型对城市化的主要动力进行比较分析,认为市场力、内源力、外向力和行政力依次是江苏省城市化发展的主要动力,其中,市场力和行政力是促进江苏省城市化和经济发展的理想动力。

Through the analysis of related literatures at home and abroad about the measurement of urbanization level and its dynamic changes, we found that China's urbanization has entered a rapid development stage and the motive forces for the development of urbanization have changed enormously. Therefore, the scientific measurement of urbanization development level and quantitative comparative analysis of its ideal powers will be particularly important to promote the level and quantity of regional urbanization. Based on the urbanized connotation, the paper constructs the appraisal index system of the synthesis level of the regional urbanization embarking population urbanization, economic urbanization, life-style urbanization and regional landscape urbanization. With the method of entropy, the generalized analyses to the evolution of the urbanization level of Jiangsu Province from 1991 to 2005 are carried out. The result shows that the urbanization of Jiangsu Province has been enhanced continuously. At the same time, the urbanization mainly represents the fast development of the economic urbanization and the regional landscape urbanization. But the population urbanization is becoming weak to the overall contribution of the regional urbanization and lagging behind other urbanizations. Economic urbanization, life-style urbanization and regional landscape urbanization have improved constantly. Meanwhile, they are turning harmonious gradually. On this basis, the multiple linear regression models are linked to the comparative analysis of the main urbanized impetus of Jiangsu Province from 1991 to 2005. Then the result is that the market forces, the intrinsic forces, the exterior forces and the administrative forces are the main powers of the urbanization development of Jiangsu Province. And the market forces and administrative forces are the ideal powers that promote the urbanization and the economic development of Jiangsu Province.
