中文摘要：

在博弈论理论的基础上，通过承运人、托运入和政府三方博弈，从经济性、迅速性、服务性和社会性四个方面建立了高铁货运和航空货运的竞争性模型。通过高铁货运与航空货运的竞争性分析，得出当日达大幅度降低首重价会造成恶性竞争，次晨达首重价可略微上调；合理减少运输时间，使承运人利润增加；提高服务性，长期内可使一方承运人利润有所回升，且对另一方承运人影响较小。政府应根据排放量的减少增加补贴，激励承运人改进硬件设备和燃料技术。基于博弈论在竞争关系下分析不同策略对高铁货运与航空货运的影响，为避免承运人间恶性竞争和政府调控市场提供参考建议。

英文摘要：

Based on game theory, conisidering the game playing of the carrier, the shipper and the government and from four aspects of economy, speed, service and sociality, we established the competition model of the high- speed rail cargo and air cargo transportation. Combining with the competition analysis, it can be concluded that the greatly reduce of the same-day-arrival first heavy freight will cause the vicious competition; the slightly increase of the next-morning-arrival first heavy freight can increase the carder＇s profits; reasonable reduce of the transportation time can increase the carrier＇s profits; service＇s improvement can make one carrier＇s profits recover, and with little effect to the other carrier in the long period of time. Increasing subsidies should provide by the government based on the reduce of emission to encourage the carrier to improve hardware equipment and fuel technology. In this paper, it also be analyzed the influence of different strategies of high-speed rail cargo and air cargo transportation under the competition relationship based on game theory, and provide advice to avoid vicious competition of the carriers and for the government to regulate the market.
