Abstract

The Ha-da giant urban belt is the most important cities concentrated distribution area in the northeast of our country, so its healthy development determines the "revitalization of the northeast old industrial base" strategy in our country, and the explore to the factors of agglomeration and spatial polarization trend have important meaning to eveal the interaction between urban space and its formation mechanism in northeast China. Nowdays, most of the study explore the regional economic polarization and space differences by using single index, the study about spatial polarization under the action of the multi-factor comprehensive is less, the driver about polarization of multi-factor space also needs to step in to investigate.This paper study the big giant within internal elements of urban agglomeration, the degree of differentiation and spatial pattern of polarization, mainly from the perspectives of comprehensive factors of agglomeration, and to explore the influence factors of its space polarization analysis. On the basis of defining the concept of the space polarization, we apply the evenness index, the Gini coefficient, Cui Wang index to analysis the urban agglomeration degree of differentiation characteristics and spatial pattern of polarization, the conclusions are as follows: 1) From 1990 to 2014, time and space differentiation of the element agglomeration degree in the big giant urban belt is obvious, and the "Core-periphery" structure lead by the central city, like Harbin Changchun Shenyang Dalian, is gradually appearing; 2) There are significant spatial polarization for element agglomeration in the giant urban belt. The "four cities"dominated the space polarization of the city belt; 3) The internal force is the main factor for the space polarization of the city belt,while urban development investment intensity and the inner attractive of the city also have significant influence on the urban space polarization.
