【摘要】 随着经济全球化过程的开始,特别是20世纪90年代以来东北地区城市化速度加快,东北地区城镇系统的整体格局发生了巨大变化。对区域空间极化问题的研究也悄然兴起。但是在以往的研究中对以人均GDP为代表的经济增长的空间极化关注较多,而对社会指标的空间极化关注较少。本文从理论与实践的角度分析了东北地区34个中心城市社会指标的空间极化情况。认为20世纪90年代以来东北地区城市与区域发生了剧烈的变化。如大城市化明显,城市体系中,哈、长、沈、大四城市的主导地位大大加强。此外,近年来的变化还表现为核心区进一步强化、地方城市边缘化、小城镇衰落、城乡融合程度发生空间分化等。伴随着经济极化,社会指标的极化也在发生着,表现出与经济极化水平相近的变化趋势,又不完全一致。本文以基尼系数、集中度、增长率为测度,对东北地区中心城市的社会指标极化情况、极化过程以及极化方向进行了考察。论文主体分为四个部分:第一部分首先阐述了研究区域、数据采集和研究方法。第二部介绍了国内外相关研究,进行了评述。并且对相关理论进行介绍和总结。第三部在分析了东北地区中心城市90年代以来的发展背景以及中心城市之间的发展差异(包括人均GDP的差异、人均收入差异和人口变动差异)的基础上,对东北地区中心城市的空间极化情况进行初步分析。第四部分首先对东北地区中心城市、四城市以及吉林省的社会指标空间极化情况进行分析,然后对具体极化的方向做进一步的分析,最后探讨极化的动力机制。结语部分概括了本文的主要结论。更多还原

【Abstract】 Along with the beginning of economic globalization,especially the speed of urbanization in northeast China has quickened since 1990s,the structure of urban system in northeast has changed a lot, the study on the regional spatial polarization has emerged silently. But in former research, it paid more attention to the economic increased spatial polarization which took GDP per person as representative, but not the spatial polarization of social index.From the theory and practice aspects, this thesis mainly analyzes the situation of urban spatial polarization based on the social index of 34 key cities in Northeast China. The writer concludes that there have been radical changes in the urban and region of the Northeast China since 1990s. For example, the phenomenon of mega polis is obvious. The four capitals ( Haerbin, Changchun, Shenyang and Dalian) have been more and more important in the dominant part of the city system. Besides, there are still other changes in recent years, for example, the central region aggrandizement, the city brinkation, the small town declination and the spatial division of the mixing degree of urban and rural. The social index has been changed with the economy polarization, putting up that polarization of social index has the similar changing trend with economic polarization, but not the same situation.This thesis consists of four parts:Firstly, it states the research scope, the data collection and the methodology.Secondly, it introduces the related theories and researches both in and abroad scholars with the comments.Thirdly, it analyzes the urban spatial polarization of key cities in Northeast China based on their development background after 1990s and the difference between them including mean GDP, income and population changes.Fourthly, it analyzes the social spatial polarization of the central cities, the four capitals and other typical cities, and then the specific polarization direction and its causing. Finally discusses the mechanism of polarization.The epilogue part gathers up main conclusion of the paper.更多还原
