中文摘要：	海铁联运具有运输量大、集疏运速度快、服务准时、能源消耗低、单位创造综合收益多等特性。中国和欧美发达国家均高度重视，并积极出台扶持政策促进发展。我国的海铁联运扶持政策与欧美国家相比，在系统性、长期性、执行力度和多样化等方面还有待进一步完善，导致各地方政府的海铁联运政策之间冲突，并未达到使公路运输向铁路运输转换的初始目标，仅是铁路运量在各海铁联运转运节点间转移，导致海铁联运市场的过渡竞争。 本文首先介绍了我国海铁联运发展和政策制定的背景，概括说明进行海铁联运补贴政策设计的充分性和必要性。然后，从交通领域常用补贴政策、海铁联运相关研究和网络模型优化相关研究等三个不同的角度梳理了国内外相关文献，在前人的研究基础上基于系统成本最小化的方法，制定了海铁联运网络流货运量配比的模型。再次，用该模型以天津海铁联运发展为基础求解了环渤海地区海铁联运的实际案例。最后给出了本文的结论和展望。经过模型和实例分析，本文认为，第一，在制定海铁联运补贴政策时，中央政府应该发挥主导作用，统筹协调各地方政府的补贴政策，才能达到社会福利总体的最大化；第二，在海铁联运中，港口城市作为海洋陆地的连接点，起龙头作用更有利于系统的发展与平衡。 文章的主要创新点在于，第一，在国内首次在海铁联运实际案例的成本计算中引入外部性成本，并考虑其对货物运输方式及转运点选择的影响；第二，本文基于环渤海区域的视角求解整个系统的福利最大化，跳出以往局限于某一城市的限制。
英文摘要：	Sea-rail transportation has many advantages than truck transportation, including a larger volume, a faster speed, a better punctuality, a lower energy consumption, and can creates more outcome per unit of input. Considering these benefits, many governments, like America, EU and China, have issued many productive policies to support the development of sea-rail transportation. However, comparing the sea-rail transportation support policies of China and developed countries, we have many things to do. For example our policies should be more systematic, comprehensive, and conducted for a longer time with enough power. In fact the current policies with many defaults have led to the benefit of different provinces conflict with each other, and the whole system can’t achieve the goal of transferring the goods conveyed by truck turn to the rail, just consulting the quantity of sea-rail transportation transfer between different cities and provinces with a lower increase speed. These all finally aggravate the contest of different provinces. Firstly, it is introduced the research background of the policy optimization design of Tianjin sea-rail transportation, and the sufficiency and necessity of the subsidy policy designed for Tianjin sea-rail transportation. Secondly, by reviewing the related literature about subsidy policies in transportation field, sea-rail transport, and network optimization, the medal is built which maximize the whole system cost to distribute the sea-rail transport network flow volume. Then, the case of Tianjin sea-rail transportation is discussed, and employed the model mentioned above to solve the problems. Finally, besides giving the research conclusion, the research deficiency and the future research prospects are proposed. The model analysis showing there are some conclusions about the best sea-rail subsidy: firstly, if the central government could coordinate the sea-rail transportation subsidy policies of different provinces, the sea-rail transport can get a better development while achieving the social welfare maximization; Secondly, it will result in a more developed and balanced sea-rail transport system with the port-city’s leadership. The article has two main innovations. The first one, it’s the first time to consider the external cost in calculating the cost of sea-rail transport in the real case and analyze its effect on the choice of the mode of transportation of goods and transshipment; The second one, this article seeks for the whole Bohai Economic Rim’s welfare maximization, not only a single city.
