在各国电子政务信息化系统建设中，高效的电子政务信息资源共享往往成为整个信息化建设的重点和难点；另一方面随着我国建立以市场经济体制为目标的改革的不断深入，日臻完善的博弈论理论在我国经济建设中的适用性越来越强，运用博弈论研究电子政务信息资源共享具有较强的理论价值和现实意义。

The principle of maximal profit is the main factor as to whether to obey credit or not. The analysis of using a game theory model once and using it repeatedly arid the analysis of a game theory model with outside intervene and evolutionary game theory analysis lead to a conclusion that strengthening cooperation and the government's power of supervision and punishment, the truthfulness of information , and a sound credit mechanism are the basic solution to the credit problem in electronic commerce.

本文运用博弈的方法，对电子商务中失信产生的原因进行了分析，认为收益的最大化原则是决定是否守信的主要因素，并通过对一次博弈、重复博弈和有外部干预情况下以及进化论博弈模型的分析，得出进一步加强交易合作的持久性、政府监管和惩罚的力度、信息的真实性以及完善的信用制度，是解决电子商务信用问题的根本方法。

There is mutual contradiction between direction estimation of user's signal and power allocation among all users in the beamforming algorithm. A twice game beamforming algorithm based on game theory is proposed to deal with it. Beamforming game algorithm mathematics model is constructed. During the first game, direction of signal and power allocation are mapped the game theory as "player", which are modeled as the problem of maximin function and obtain direction estimation first. Then during the second game, power allocations of different users are described as a multi-user game. Power updated algorithm is designed. The existence and uniqueness of the Nash equilibrium in the twice game beamforming algorithm based on game theory are proved by mathematics derivation.

摘要针对波束成形算法中，用户的信号方向估计值和用户之间的功率分配存在着相互矛盾，本文提出了一种基于博弈论的二次博弈波束成形算法，构建了波束成形博弈算法数学模型，首先在第一次博弈的时候，将波束成形算法中的信号方向和功率分配映射为博弈论数学模型中的"局中人"，将其建模为函数的极大极小值求解问题，先求解出信号方向；然后在第二次博弈的时候，将不同用户的功率分配过程描述为一个多用户的博弈过程，设计了功率分配更新算法，通过数学推导论证了纳什平衡点的存在性和唯一性。

This paper also applies game theory to set up game models for ante-accommodation and post-accommodation. In the information model for ante-accommodation, commercial banks expect the occurrence of separate game equivalence not the pooled game equivalence, for in pooled game equivalence, commercial banks may easily choose adverse selection to provide loans because of asymmetric information, while in the supervision model for post-accommodation, banks and enterprises hardly make pure strategic equivalence, that is, they can not achieve Pareto optimum in the same time, meanwhile, when the supervision model for post-accommodation achieve pooled strategic equivalence, we will make use of probabilities of enterprises not keeping their promises and probabilities of bank supervision as indexes for describing qualitatively the credit risk for enterprises and the credit risk for bank supervision.

首先，论文对信贷活动中信息不对称所产生的逆向选择与道德风险及由此产生的信贷风险进行了一般理论分析，并提出了防范逆向选择和道德风险的一般模型；其次，论文结合我国信贷市场预算约束软化这一根本特征，研究了我国信贷活动中由信息不对称而产生的信贷风险形成机理的特殊性进行了分析；接着，运用博弈论方法对我国信贷市场中商业银行与企业在申请贷款、偿还贷款时的博弈行为进行了深入分析；最后，文章提出了消除信贷市场信息不对称的对策和建议。

Besides many papers specially on studying game theory and its application, game theory is also becoming a common tool in economics field and subject of both theory and application.
