摘　　要：公路规模与经济产出在理论上服从异速生长定律,本文利用2004年~2015年全国各行政区公路里程、GDP数据分别建立了时间维度和空间维度的公路规模-经济产出的异速生长模型。模型表明:各行政区在时间维度的公路规模-经济产出之间符合异速生长规律,分形特征明显;从空间维度上看,公路规模-经济产出之间的异速标度指数呈下降趋势,随着近10年公路建设的加速,公路交通运输对区域经济发展的制约得到明显缓解,公路运输对区域经济发展引领态势加强。The relationship between scale of highway and economic outputs is supposed to follow the law of allometric growth.In this paper,the allometric growth models of highway sizes-economic outputs are established by using the road mileage and GDP data of the 2004-2015year national administrative regions.The model shows that the highway sizes and economic outputs of the administrative region follow the law of allometric growth in time dimension,the fractal characteristics of time dimension is obvious;from spatial dimensions,allometric scale index of highway sizes-economic outputs is declining in recent ten years.With the acceleration of highway construction in recent 10years,the restriction of road traffic on social economy has been alleviated.The restriction of highway transportation to the development of regional economy has been alleviated obviously,and the road transportation has strengthened the leading trend of regional economic development.
