从空间视角研究煤炭与经济的关系,可为国家的产业空间布局决策提供重要依据。本文运用重心法,测算了2000-2010年度我国煤炭储、产、消以及经济的重心位置、重心移动距离和方向,分析了各重心的演变路径,对煤炭供需与经济重心的演变路径进行了比较分析。研究结果表明:煤炭储、产、消和经济的重心空间布局呈现从西北到东南分布的特点;生产重心演变轨迹最大,经济重心演变轨迹最小;产消的重心距离逐渐拉大,由2000年的230公里演变到2010年的333公里;煤炭供需与经济重心存在显著的相关关系。依据研究结论,提出了产业空间布局的相关政策建议。
Studying the relationship between coal and economy from a spatial perspective can provide an important basis for the country\'s industrial spatial layout decision-making. In this paper, the center of gravity, the center of gravity, the distance and direction of center of gravity of coal storage, production, consumption and economy in China from 2000 to 2010 are calculated and the evolution paths of each center of gravity are analyzed. The evolution of coal supply and demand and economic center of gravity are compared analysis. The results show that the spatial distribution of gravity center of coal storage, production, consumption and economy presents the distribution from northwest to southeast. The evolution trajectory of production center of gravity is the largest and the trajectory of economic center of gravity is the smallest. 230 km to 333 km in 2010; there is a significant correlation between coal supply and demand and economic focus. According to the conclusion of the research, the paper puts forward the relevant policy suggestions on the industrial spatial layout.
