摘　　要：为了实证研究运输对区域经济增长的影响,构建包含交通因素的柯布道格拉斯模型,以2009年底全国各省份第二产业劳动力、资本以及各省交通运输要素作为投入,以2009底年各省份的第二产业GDP作为产出,对拓展的柯布-道格拉斯模型进行回归分析,验证该模型的合理性,进而利用该模型定量地分析交通运输对区域经济增长的贡献,结果显示资本是经济增长最重要的影响因素,交通运输和劳动力要素亦显著影响区域经济的增长.In order to analyze transportation^s impact on regional economy development, the extended Cobb-Douglas Function is established which includes transportation factor. The labor, capital and transportation factor of each province in 2008 are regarded as input while the GDP of secondary indus- try of each province is regarded as output, then analyzes the rationality of the extended model, and calculate transportationrs contribution to economy development by the established model, and the re- sult indicates that capital is the most important factor contributing to economy growth, transportation and labor factor also impact economy growth significantly.
