摘要
利用 1 996年世界 1 1 6个国家的截面数据 ,分析了铁路网密度与人口密度、人均GDP的关系 ,建立了一个统计模型来反应国家铁路网建设的宏观需求 ;提出了依赖 偏好指数的概念 ,分析了地理环境、资源产业结构、建设历史及政策偏好等因素对国家铁路网建设的影响 ,解释了模型值与统计值之间的偏差 .
This paper analyses the relationship between railway density with population density and per capita GDP in international, on the basis of the section data of 116 countries in the world at 1996, and setup a statistic model showing macro demand of a country′s railway net.
