江西省县域城镇化水平测度及其分异研究

根据人口、经济、社会、土地等城镇化的四个主要方面,构建了城镇化水平测度的综合指标体系,采用熵权法对江西省2001年和2010年各县(市)城镇化水平进行了综合评价,并对其时空分异特征及成因进行了分析。研究发现:①江西各县(市)城镇化综合水平自2001年以来均获得了不同程度的提升,县域城镇化水平变异程度减小,但绝对差距和相对差距拉大,极化趋势显著;②江西省城镇化水平存在显著的区域差异,从北向南呈现由高向低的梯度变化规律;县域城镇化水平高和较高的县(市)主要分布在全省的西北、东北、中部和西南部地区;空间形态上形成以中心城市为核心,向外围梯度变化的圈层式结构;③江西省县域城镇化水平差异是自然条件和资源禀赋、中心城市辐射带动能力、地理区位和交通条件及区域发展战略和政策等方面的差异综合作用的结果。

A STUDY OF THE COUNTY -LEVEL URBANIZATION AND ITSDIFFERENTIATION IN JIANGXI PROVINCE

This paper constructs a comprehensive index system to measure the urbanization level of Jiangxi Province. The system covers four dimensions of urbanization including population, economy, sociality and land. Based on this measure system, it further uses entropy method to evaluate the urbanization levels of the counties in the province in 2001 and 2010, and analyzes its spatial-temporal characteristics and the reasons for them. The research findings are summarized as follow. Firstly, the urbanization levels of all counties in Jiangxi have risen in different speeds since 2001, but there has been an increasingly widening gap between them and emerged a trend of polarization. Secondly, there are significant regional differences in the levels of urbanization of Jiangxi Province. Thirdly, such differences result from multiple factors, including the natural condition and resource endowment, the leading ability of the central cities, geographical location and transportation condition and regional development policies and strategies. The urbanization speed of the former is slower than that of the latter. Compared with the adjacent provinces such as Henan and Anhui, in Jiangxi, theeffect of the polymerization of urbanization development is limited. And the spatial pattern of urbanization isnot rational enough, but fragmentized. In order to promote the development and improve the quality of urbanization, it is thus suggested that the policies should point to the enhancement of the radiating and driving ability of the central cities, full use of national development policies, and acceleration of economic development in the counties and improvement of the infrastructure system among them.
