公路基础设施对东北地区城镇化贡献的空间计量分析

The Spatial Measurement Analysis of the Contribution of Highway Infrastructure to Urbanization in Northeast China

公路基础设施对城镇化发展有着越来越重要的作用,主要通过用空间计量方法,实证分析公路基础设施对东北地区的城镇化影响.从而得出:(1)在东北地区内,公路对东北地区城镇化的发展产生的贡献是正向的,并且因此产生了一种"局部趋同、总体分异"的空间格局.(2)在公路设施里,高速公路对东北地区城镇化发展贡献最高,其次是一级公路与二级公路,最低的是三四级公路,对城镇化贡献影响不明显.因此从这种趋势可以总结出公路设施对东北地区城镇化贡献产生了一种"高等级公路偏好"的效应.

Road infrastructure to urbanization development is playing an increasingly important role,the highway infrastructure contribution to urbanization in northeast China are analyzed by using spatial econometric method. The results show（ 1） In the northeast region, Highway ’ s contribution to the development of urbanization in northeast China is positive,and therefore produced a ＂ local convergence,overall differentiation＂ spatial pattern.（ 2） In highway facilities,Highway contribute to the development of urbanization in northeast China is highest,the second is the primary roads and secondary roads,three fourth class roads,are the lowest contribution to urbanization effect is not obvious. Therefore,this trend can be summarized as the effect of highway facilities on urbanization in northeast China.
