摘　　要：为比较公路、普通铁路、高速铁路三种交通方式对京津冀空间相互作用强度贡献率的大小,文章基于是否考虑货币成本两种情况下构建三种不同的路网系统,利用重构的引力模型和潜力模型进行定量分析。结果表明:公路对京津冀空间相互作用的贡献率最大,基于最小综合成本和最小时间成本的贡献率分别达到83.5%和73%,表明京津冀各城市间的经济文化交流对公路的依赖程度很高;高速铁路可以极大缩短城市间出行时间,但票价的增加大体中和时间成本的节省,基于最小时间成本的贡献率为22.2%,大大高于普通铁路的4.8%,且其带来的空间相互作用强度的增加沿着北京、天津、石家庄、邯郸等站点城市显现出明显的廊道效应。To compare the contribution rate of three transportation styles(highway,normal-speed rail and high-speed rail)to the spatial interaction strength of Beijing-Tianjin-Hebei,this paper,based on two situations considering monetary cost or not,constructs three different road network systems,and applies the modified gravity model and the potential model to do quantitatively analysis.The results show that the highway has the largest contribution rate to the spatial interaction of Beijing-Tianjin-Hebei,and the contribution rates based on the minimum comprehensive cost and the minimum time cost respectively reach 83.5%and 73%,indicating that the economic and cultural exchanges between the cities of BeijingTianjin-Hebei are highly dependent on the highway.Besides,high-speed rail can greatly shorten the travel time between cities,but the increase in fare generally counteracts time cost savings.The contribution rate based on minimum time cost is 22.2%,which is much higher than the 4.8%of normal-speed rail.And the increase of the spatial interaction strength brought by high-speed rail has obvious corridor effects along the site cities such as Beijing,Tianjin,Shijiazhuang and Handan.
