兰渝铁路辐射带经济空间差异及其对策研究

以兰渝铁路沿线120 km范围内的主要行政单元为研究对象,选取衡量经济发展的9个指标,运用主成分分析法揭示辐射带经济差异,同时运用Geoda软件提供的空间分析方法揭示辐射带经济差异的空间分异特征。分析结果表明,辐射带经济发展水平差异显著,在地理空间上存在集聚性；铁路的重庆段为铁路经济发展的热点区,辐射带内除重庆外无二级节点城市引导经济发展,重庆的经济辐射能力随距离的增加呈现出明显的衰减效应。在此基础上分析了影响兰渝铁路辐射带经济发展的主要因素,并提出相应的发展对策。

Spatial Difference of Economic Development in Lanzhou-Chongqing Railway Economic Radiation Belt

Understanding spatial pattern of economic development is important to make the developing plans and to guide the industrial distribution in railway economic radiation belt.Selecting 9 economic indices and using the SPSS software and the spatial analysis method provided by the Geoda software,we analyze the spatial difference among the main administrative regions within area to 120 km away from the railway route.Results show that there are great spatial differences in economic developmental level,demonstrating geographical concentration phenomenon in the railway economic radiation belt.Chongqing city is an important economic hot spot,and except for Chongqing there is no other node-city that drives the economic development.So with the increasing of distance from Chongqing,the radiation capacity of Chongqing becomes weaker and weaker.In this paper,we also put forward some countermeasures and suggestions after analyzing the main influencing factors of the economic development.
