摘要近几年，银行和信托公司的合作越来频繁和深入，国内商业银行经过几十年的发展在传统业务上愈发成熟，与信托的合作是成为了重要的金融创新手段。而繁荣的信托业也成为了第二大金融产业，仅次于银行。但是，现在银行和信托的合作模式已经越来越不符合发展趋势，形成了“银强信弱”的场面，需要创新改革。论文尝试从合作博弈的角度研究银行和信托的合作过程，推导出利益分配方面合理公正的比例。论文依据合作博弈理论，通过建立信托和银行的收益模型，研究银行和信托的合作博弈，利用纳什讨价还价解和shapley值这两种方法给出博弈结果的均衡解，即利益分配的合理比例，然后再加入风险因素对利益分配解的修正，求出符合实际的利益分配比例，给出关于利益最大化的策略。19564
论文的主要结论为：
（1） 在银信合作中，银行的资金规模和信托的努力程度是相互依赖的，即为了保证利益的最大化，S和A的增加必须是具有正向的线性关系。
（2） 从合作博弈角度建立的银信合作模型中，局中人为了获得联盟整体利益的最大化，努力程度或者资金规模要高于非合作状态，这样才能有效避免合作中的投机行为，因此， 必须要满足 。
（3） 在利益分配机制中，根据shapley值的方法，信托需要提高合作后的总利润和合作时的“底线”，而银行需要提高自己跟信托合作后带来的边际盈利。在风险方面，双方都应采取一个适中值。

Title study on cooperation between banks and trust based on the cooperative game theory
Abstract
For the past few years, cooperation between the bank and the trust has been deeper and more and more frequent. Traditional business of domestic commercial banks has been more and more mature, so, for banks, choosing to cooperate with the trust is an important approach for financial innovation. Benefiting from cooperation with banks and economic development, the trust has been the second financial industry, second only to the banks. However, nowadays banks and the trust’s cooperation pattern has become unsuitable for development trend, and the cooperation pattern has preferred for the banks. It’s urgent to innovate and reform. The article intends to discuss the cooperation between banks and the trust from the perspective of cooperative game theory, in order to induce an appropriate ratio of profit distribution. The article first establishes utility function to study the cooperation, then uses Nash axiom and shapley method to get the equilibrium solution, namely an appropriate ratio of profit distribution, then introduces risk factor to correct above model for a more practical solution, at the last, gives some advice to maximize distributed profit of banks and the trust.
The thesis gets conclusion that:
1, during the cooperation, fund scale of banks and level of effort of the trust depend on each other, that’s to say, in order to maximize profit, increases of S and A must have linear positive relationship;
2, in the cooperation mechanism based on the cooperative game theory, each member’s fund scale or level of effort needs to be higher than those under non-cooperative state for the maximum of overall profit. in this way, it’s highly possible to avoid opportunistic practice. Thus, must to satisfy the inequality ;
3, in the profit distribution mechanism, according to the way of shapley, the trust should increase the overall profit and “bottom line” after the cooperation; banks should increase its marginal profit. as for the risk, both should determine an appropriate ratio based on its practical situation. 银行和信托的合作博弈研究+文献综述:http://www.751com.cn/jingji/lunwen_10976.html
