政策性金融与商业性金融相关性的博弈论分析

A Gaming Analysis on the Relevance of Policy Finance and Commercial Finance

博弈分为非合作博弈和合作博弈。非合作博弈下,政策性金融与商业性金融表现为负向互动的不公平纳什均衡;合作博弈下,二者则表现为正向互动的合作均衡。应该通过专门立法的形式,制定一个促进双方共同遵守的具有强制约束力的“承诺”,即制度规则,从而使政策性金融与商业性金融之间达到合作均衡。此外,为推进我国政策性银行的可持续发展,其改革方向应该是政策性业务与非主动竞争性盈利的有机统一,即政策性、盈利性和非竞争性的“三位一体”。

There are two kinds of gaming： non -cooperative gaming and cooperative gaming. Under non -cooperative gaming, policy finance and commercial finance take on a negative interactive unfair Nash equilibrium; under cooperative gaming, they take on a positive interactive cooperative equilibrium. Specialized legislation should be followed to formulate an ＂undertaking＂ with obligatory binding power, which can promote mutually abiding, that is, institution rule, hence making a cooperative equilibrium between the policy finance and commercial finance. Besides, for promotion of sustainable development of China＇ s policy banks, the reform direction should be a unity of policy banking transaction and non - active competitive earnings, i.e. a ＂trinity＂ of policy, profitability and non - competitiveness.
