Abstract: From the differences of the development of transportation industry in China, the difference impact of transportation on the regional economy is analyzed using Theil index method to measure the difference between areas and regional internal, to calculate Theil index respectively select passenger volume, passenger turnover, freight volume, freight turnover for weighting, and to analyze the contribution of different regional differences to the overall difference. The results show that the transportation industry in China has significant influence on the regional economic development, especially that the regional internal differences, the eastern region of the difference have the largest contribution, but there is a downturn in the contribution of the difference and the difference between regional contribution is on the rise.

Key words: transportation, regional economy, Theil index

摘要： 本文从我国交通运输业发展的差异性入手，分析交通运输业对区域经济影响的差异性，运用泰尔指数方法测度我国区域之间以及区域内部的差异程度，分别选取客运量、旅客周转量、货运量、货物周转量为权重，计算相关泰尔指数，并分析不同区域差异性对总体差异情况的贡献度。结果表明，我国交通运输业对区域经济发展影响差异显著，尤其是区域内部差异较大，东部地区对这种差异贡献度最大，但是区域内部对这种差异的贡献度有下降趋势，而区域之间对差异的贡献度呈上升趋势。
