国家区域公路网密度与人口密度、人均GNP关系的统计分析

利用３个时段截面数据，分析职国家区域公路网密度与人口密度、人均ＧＮＰ的关系，发现他们具有稳定数学关系式和统计规律；考虑到公路网建设受资源产业结构、公路网建设政策，其它运输方式的影响，提出了公路网依赖－偏好指数的概念，解释了公路网密度实际值与模型计算值的偏差。此研究可为国家区域公路网与人口、经济协调发展提供基础理论。

Statistics Analysis on the Relationship of Highway Net Density with Population Density and Per Capita GNP in National Region

The relationship of the highway net density with the population density and per capita GNP in a national region is analyzed by use of the section data of three different times, and it is found that among them there exists a stable mathematical relation and a statistics law. Considering that the highway net building is influenced by the industrial structure of resources, the highway net construction policies and the other transport patterns, a concept of highway dependence favoritism index is put forward, which is used to explain the variation between the actually obtained highway net densities and the values obtained by model calculation. This study can afford a fundamental theory for the harmony development of national highway network, population and economy.
