分析1996–2011年中国整体和四大经济地带的公路交通发展，以及区域经济发展空间差异及其相关关系。得出基本结论，公路交通发展的空间布局差异显著，呈现出与经济发展类似的地带性空间分布特征；公路交通发展空间差异长期范围内呈增长趋势，各区域内差异是导致整体空间差异过大的主要原因；区域经济发展的空间差异低于交通建设发展的空间差异，由于政策的引导，近年呈现降低趋势，经济发展的空间差异主要来自于区域间的差异，影响程度将近70%；公路交通空间差异及区域经济空间差异间具有显著的正相关关系。加强公路交通发展区域均衡性能够降低经济发展的空间差异，促进区域均衡发展。

The Spatial Difference and Correlation Analysis of Highway Development and Economic Development in China

This paper calculates the Theil coefficient and Gini coefficient of the highway development and economic development, studies the spatial difference and correlation of highway and economic development. The calculations are that: The spatial difference of highway traffic infrastructural construction is significant. The difference of the spatial and temporal variation of highway construction has a tendency to increase in the long run. And the difference mostly comes from the regional differences of four economic regions； The difference of the spatial and temporal variation of economic development is little than the one’ s of highway. The difference main comes from the difference between four economic regions, and the influence degree is up to 70% . There are significant correlation between the difference of spatial and temporal variation of highway and the ones of economic development.
