Abstract:

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.

Key words: ransportation economy, spatial difference； correlation analysis, highway infrastructure, Theil coefficient, Gini coefficient
