兰渝铁路辐射带的经济差异及原因

Economic disparities and reasons analysis to the Lanyu Railway Radiation Belt

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。

Based on the index of per capita GDP, spa- tial - temporal patterns of economic disparities have been probed into by the method of spatial autocorre｜ation analysis. The main study areas are along the Lan - Yu railway within 120kin. The a- nalysis 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 weaker with the distance enlarges. Based on the status of the spatial differentiation of thebelt, the main influence factors of the economic disparities are discussed, such as the resources endowments, policy regimes, investment environment and regional soft power and so on.
