兰渝铁路辐射带的经济差异及原因

以人均GDP为主要测度指标,采用GeoDA软件提供的空间分析方法,以兰渝铁路沿线120公里范围内的主要行政单元为研究对象,分析了兰渝铁路辐射带的经济空间分异状况。结果表明:辐射带经济发展水平差异显著,在地理上存在较强的空间依赖性;经济发展的热点区域位于重庆境内,是整个铁路辐射带内的唯一辐射中心,另一个端点城市兰州的辐射能力弱;区内无二级节点城市引导经济发展,因此随着距离的增加,重庆的经济辐射能力呈现出明显的衰减效应。在此基础上,从资源禀赋、政策体制、投资环境、区域软实力等角度分析了影响兰渝铁路辐射带经济差异的主要原因。

Economic disparities and reasons analysis to the Lanyu Railway Radiation Belt

Based on the index of per capita GDP,spatial-temporal patterns of economic disparities have been probed into by the method of spatial autocorrelation analysis.The main study areas are along the Lan-Yu railway within 120km.The analysis shows that there are great differences in the economic level;Chongqing is the only one economic hot pot in the belt,however,Lanzhou has a poor radiation ability;Because there is no other node-cities to guide the economic development,the radiating capacity of Chongqing become w...
