本文探讨现代社会科学的统一分析框架对法学理论的建设性推进。我们展示了个体理性决策与博弈论,社会选择与机制设计理论的主要思想,并初步讨论了它们在法律问题中的运用。其核心观念为:法律与其它社会规范一起为组成社会的所有行为主体提供了制度激励,立法者任何合乎社会正义理念的目标,只有作为他们在社会博弈中的均衡行为的结果,才能得到合理实施。 This article explores the constructive promotion of jurisprudence theory by the unified analytical framework of modern social science. We show the main ideas of individual rational decision making and game theory, social choice and mechanism design theory, and discuss their application in legal issues. The core idea is that law and other social norms provide institutional incentives for all the actors that make up the society. Any legislator’s goal of social justice can only be reasonably implemented as a result of their balanced behavior in the social game .
