重庆市人口与经济发展空间耦合分布研究

本文基于2001-2012 年重庆市各个区县的人口和经济数据,计算重庆市各区县的人口地理集中度和经济地理集中度并结合耦合指数,分析人口分布与经济分布耦合特征与人口与经济空间分布类型,并运用Geoda、ArcGIS 软件对重庆各个区县人口与经济的全局和局部空间自相关分析,建立人口与经济发展耦合度模型与耦合协调度模型,分析人口与经济的空间耦合度的特征。研究结果表明：①重庆市的人口与经济整体水平有较好的发展趋势,但区域发展差异明显。②人口集中度和经济集中度总体上呈现“一圈高,两翼低”的特点。③2001-2012 年间重庆市人口与经济耦合度总体呈上升趋势,且人口与经济间的耦合作用不断增强。

SPATIAL COUPLING DISTRIBUTION OF POPULATION AND ECONOMIC DEVELOPMENT IN CHONGQING

Based on the population and economic data from 2001 to 2012 in Chongqing, this paper computes the geographic concentrations of population and economy. The geographic concentration is regarded as an effective indicator to measure spatial distribution of population and economy by integrating the factors of regional population, economy, and area. Then, the coupling indicators are employed to monitor the mutual coupling characteristics and spatial distribution classification of population and economy. Both the overall and the local spatial autocorrelation analysis on the coupling indicators of population and economy are carried out by using Geoda and ArcGIS software. At last, this paper establishes the coupling degree model and the coupling coordination model of population and economy development. The results demonstrate that, 1） the overall level of population and economy in Chongqing has good developing tendency, but the differences in regional development are significant. 2） the geographic concentrations of population and economy with the distinctive spatial distributions show the general tendency featured by, "one circle is high and two wings are low".The counties of economic advanced type in Chongqing are increased; those of economic coordination type are partially transferred; those of economic development type are increased; those of economic backward type remain essentially unchanged. 3） The coordinated development level of population and economy in Chongqing is not balanced.
