【摘要】 伴随着经济的日益全球化,我国铁路货物运输代理业务正在受到来自国内外的前所未有的挑战。在这样的环境下,我国的铁路货运代理业务将何去何从。正是在这样的背景下,本文对铁路货运代理业务第三方物流的问题作了详细的探讨。在我国现有的条件下,实施铁路货运代理的第三方物流无疑是最佳的选择。本文分析了铁路货运代理业务向第三方物流转化的条件,面临的机遇和挑战,以及第三方物流的组建,并且着重分析了代理企业和货运企业最关心的问题——利益分配问题。货运企业努力和代理企业努力的生产函数的之间的常替代弹性,所以本文分为分享产出模式和固定产出模式两种情况进行讨论。在产出分享模式下,本文基于张维迎(1995)的模型,由于我国铁路货物运输的垄断性并考虑到我国的实际情况引入了勒纳指数,分别对存在外部人和不存在外部人的情况进行了分析。在不存在外部人的情况下,代理企业的相对重要性较弱时,其剩余份额随勒纳指数(Lerner Index)的增加而增加,即侵占了货运企业的剩余分额,其原因在于二者的合作存在着外部性。在存在外部人的情况下,代理企业的相对重要性较弱时,剩余份额随勒纳指数的增加而减少,也就是说随着货运企业的垄断力的上升,代理企业得到了更少的份额;而当代理企业的相对重要性较强时,剩余份额随勒纳指数的增加而增加。对存在外部人和不存在外部人的情况进行比较,证明了外部人存在的必要性,并且在分配系数变化之中,相对重要性起了决定性的作用,从而得出代理企业要加强自己的核心竞争力的结论。本文还通过数据模拟得出我国现实中代理企业的剩余份额太小,这也可能是代理企业发展缓慢的一个原因。并且得出由于垄断力量的存在,弱化了外部性的存在,从而达到了一种接近帕累托最优的状态的结论。而在固定模式下,基于霍姆斯特姆(Holmstrom,1982)的模型,弥补了以上模型设定的问题。即使在一方在剩余份额为零的情况下,由于考虑到多期的利润企业最大化也不得不提供努力。

【Abstract】 Accompanying with economy increasingly a globalization, the railroad goods conveyance agency business is subjected to unprecedented challenge from the domestic and international. Under such conditions, where will our country railroad freight transportation agency business go? This article has made the detailed discussion to the railroad freight transportation agency business existing problem. It is the best option to carrying out the stratagem of the TPL under the existing conditions. This article analyzed the condition、opportunity and challenge of the conversion, the foundation of the TPL, and attached the importance to analyzing the profit allocation problem which both the business enterprise and the freight transportation business enterprise concerned .Under the model of the output-share, this article introduced the Lerner index considering the rendered social settings in china and analyzed the conditions existing exterior person and not exterior person according to the Weiying Zhang’s model(1995).The agent enterprise’s surplus share go hand in hand with the Lerner index in case the proxy enterprise’s relative importance is weaker when not existing exterior person. The agent enterprise’s surplus share increases with the decrease of Lerner index in case the proxy enterprise’s relative importance is weaker when existing exterior person. In other words the proxy enterprise requestes more shares with the freight transportation enterprise’s monopoly influence dropping which is consistent with our intuition. This article also concluded the proxy enterprise’s surplus share is too small through the data simulation, which might be the cause of the slow development of the proxy enterprise. But under fixed pattern,the article based on Holmstrom’s model(1982), made up the model hypothesis question. The side has to work hard even if a side’s surplus share is zero considering the life-long profit maximization.
