Coordinate Development among Population,Land and Economy Urbanization in Developed Area:The Case of Jiangsu Province

This paper aims to examine the coordinate development among Population urbanization,land urbanization and economy urbanization in Jiangsu province which is a typical delegate of developed area in the eastern coastal provinces.The authors point out that in the new period the urbanization is a complex system,it is a process of population to the town's concentration,transformation and differentiation and a regional advance process of urban landscape,also a process of economic transformation.After reviewing the definitions of the urbanization,the authors believe the levels of urbanization can't be only measured by population urbanization,but by Population urbanization land urbanization and economic urbanization.Recently,Jiang Su is in the accelerated development period of urbanization,Population keeps growing agglomeration,urban land scale expands unceasingly,urban economic developments quickly,Though time-series calculations,the author finds that the indexes of population urbanization level,land urbanization level and economy urbanization level from the 1998 to 2009 are in a trend of continuing upward,and during the period,the coordinate level of them is also gradual increasing.At the same time,in different stages the dominant driving forces of urbanization is different;the coordinate development is rising during the period,from the stage of recession development(1998-2003),gradually to a transitional phase(2004-2005),and finally to the stage of coordinate development(2006-2009).From the view of spatial pattern,through the comprehensive evaluation 2009,the urbanization level and the coordinate development of the overall level is high in Jiangsu province,but the overall development of urbanization level regional differentiation.
