Population-Economy-Space Urbanization of Northeast China

Urbanization is apopulation-economy-spacetrine progress,and the coordination among them is the key to the sustainable development of city.In order to evaluate the coordination of the population-economy-space urbanization in Northeast China.In the article,firstly,the indexes of population urbanization,economy urbanization and space urbanization were constructed,and the standard variance method was used to make sure the weighs of eacry index,and then the 34 prefecture-level cities(mainly referring to the three in Northeastern provinces) were took as the research object,to measure the urbanization level of population,economy and space comprehensively.Secondly,the coordination estimate model was used to assess the coordination among of them,and then the coupling degrees was used to divide the 34 prefecture-level cities into several groups.The result shows that: ① The economy urbanization of Northeast China was leading the population urbanization and space urbanization and the whole level wasn’t high,basically at the average level from 0.25 to 0.35,which means it stated in the accelerating development stages.② the spatial differentiation characters of population urbanization,economy urbanization and space urbanization were very significant,in which the population urbanization showed a decreasing trend from north to south,while the economy urbanization showed a decreasing trend from south to north,between theminner-complementary(internal difference)character appeared very clear.③ The coordination degree among population urbanization,economy urbanization and space urbanization was very small,and the regional differences were so significant that the degree showed decreasing trend from south to north.④ According to the dominant coordination degrees among population-economy urbanization coordination degree,population-space urbanization coordination degree,economy-space urbanization coordination degree,the 34 prefecture-level cities were divided into 4 types.
