【摘要】：区域经济空间分异的研究一直是众多学者讨论的热点话题,而流域作为一种特殊的区域,对其经济的空间分异研究更具有特殊的重要意义。本文以淮河流域为研究对象,以县域为研究单元,从淮河流域经济格局时间演变、空间演变和分异机制三个方面出发,选取1990年到2010年的相关数据,采用多种方法对淮河流域经济空间分异进行分析。首先采用标准差、空间基尼系数、空间分异指数、泰尔指数,对淮河流域经济格局的时间演变进行分析,得出其1990-2010年间经济空间分异的总体趋势,并对流域内部四个省份的泰尔指数进行分解,结果表明淮河流域从1990年以来县域经济差异呈波动扩大趋势,区域经济发展的发散程度不断加大。其次通过全局空间自相关指数、局域空间自相关指数、Getis-Ord Gi*、相对发展率(NICH指数)、趋势面分析等相关度量指标和方法的运用,将淮河流域分为高位集聚区、低位集聚区、低位扩散区和高位扩散区四种类型区域。发现淮河流域经济空间全局分布呈现出集聚的趋势,且集聚态势逐渐显著；同时经济空间格局呈现出相对稳定的态势,逐渐形成以西北部和东南部为主要极化区的空间格局态势；近年来淮河流域经济重心一直分布于流域西北部与东南部,经济发展水平较低的区域一直位于流域中部。最后选取劳动力、资本、工业化、财政支出、人口密度、城镇化率、交通通达度因子和区域政策优先度是影响因子,利用拟合度较好的空间误差模型(SEM)和地理加权回归模型(GWR)对淮河流域经济空间分异的机制进行分析,发现不同因子的贡献率不同、同一因子的不同地区影响程度不同、不同时期影响因子的空间分布不同等相关结论,研究结果将为淮河流域各级政府制定政策提供相应依据。
[Abstract]:Research on regional economic spatial differentiation has been a hot topic discussed by many scholars, and the river basin as a special region, the economic spatial differentiation of it has a special significance. This paper takes Huaihe basin as the research object, takes the county as the research unit, from the time evolution of economic structure of Huaihe Basin, spatial evolution and the differentiation mechanism of the three aspects, from 1990 to 2010 data, using a variety of methods of economic spatial differentiation in Huaihe basin were analyzed.
First, using standard deviation and spatial Gini coefficient, spatial difference index, Theil index, on the economic situation of Huaihe basin evolution analysis, the overall trend of the economic spatial difference between 1990-2010, and the four provinces in the Theil index, the results show that the Huaihe basin since 1990 the county economy difference is the fluctuation trend of expansion, the level of divergence of regional economic development is increasing.
Secondly, through the global spatial autocorrelation index, local spatial autocorrelation index, Getis-Ord Gi*, relative development rate (NICH index), trend analysis and other related measures and methods, Huaihe river basin can be divided into high concentration area, low concentration area, low diffusion zone and high diffusion region four types found in Huaihe area. In the economic space of global distribution shows a gathering trend, and the trend of convergence and gradually significant; the economic spatial pattern showing a relatively stable trend, gradually formed the spatial pattern of situation to the northwest and southeast as the main polarization region; in recent years, the economic center of Huaihe basin has been distributed in the Northwest and southeast of the basin, the level of economic development the lower region has been located in the middle part of the basin.
The final selection of labor, capital, industrialization, fiscal expenditure, population density, urbanization rate, traffic accessibility factor and regional policy priority is the impact factor, using the fitting degree of spatial error model (SEM) and geographically weighted regression (GWR) analysis on the mechanism of the economic spatial dissimilarity in Huaihe Valley, found that different the contribution rate of different factors, different regions with different factors, different factors affecting the spatial distribution of different periods and other relevant conclusions, the research results will provide for the Huaihe basin at all levels of government policy should be based on phase.
