【摘要】：在界定空間極化概念的基礎(chǔ)上,應(yīng)用均勻度指數(shù)、基尼系數(shù)、崔王指數(shù)分析城市帶內(nèi)部要素集聚程度分異及空間極化格局,結(jié)論如下:(1)1990—2014年哈大巨型城市帶要素集聚程度時(shí)空分異明顯,"核心—邊緣"結(jié)構(gòu)逐步顯現(xiàn),城市帶內(nèi)部基于要素集聚程度的哈長(zhǎng)與遼中南次區(qū)域逐漸發(fā)育;(2)城市帶內(nèi)部要素集聚存在顯著的空間極化,空間極化的"四城市"格局已經(jīng)形成;(3)城市發(fā)展內(nèi)源力是哈大巨型城市帶整體空間極化的主要影響因素,城市投資強(qiáng)度和經(jīng)濟(jì)發(fā)展水平對(duì)城市帶空間極化格局演變的影響也較顯著。城市投資強(qiáng)度與吸引力差異是哈長(zhǎng)次區(qū)域空間極化分異的重要影響因素,而城市發(fā)展內(nèi)源力是影響遼中南次區(qū)域空間極化的主要因素。
[Abstract]:On the basis of defining the concept of spatial polarization, this paper applies the evenness index, Gini coefficient and Cui Wang index to analyze the degree of concentration differentiation and spatial polarization pattern of urban inner elements. The conclusions are as follows: (1) from 1990 to 2014, the spatial and temporal differentiation of the concentration degree of elements in the mega-urban zone of Harbin is obvious, and the "core-edge" structure gradually appears. In the urban belt, based on the degree of factor agglomeration, Ha-Chang and the sub-region of central and southern Liaoning gradually develop. (2) there is a significant spatial polarization in the internal factor agglomeration of the urban belt. The "four cities" pattern of spatial polarization has been formed. (3) the endogenous forces of urban development are the main influencing factors of the overall spatial polarization of Harbin megacities. The influence of the intensity of urban investment and the level of economic development on the evolution of spatial polarization pattern of urban zone is also significant. The difference of urban investment intensity and attraction is an important factor in spatial polarization differentiation of Harbin and Changzhou sub-region, and the endogenous force of urban development is the main factor that affects spatial polarization in central and southern Liaoning sub-region.
