法经济学分析范式的构建

On the Establishment of the Analysis Paradigm of Law and Economics

法经济学分析范式需要解决的首要问题,是运用边际分析法求解对诸如个人效用最大化、政府税收最大化等最优化问题。通过边际分析方法求得的具有相互联系的行为主体的最优化行为的集合便是均衡,这也正是法经济学分析范式的核心概念。法经济学分析范式的最终任务是对行为主体的最优化行为共同构成的均衡进行效率评估,也即考察某种均衡是否符合效率标准。由此可见,法经济学分析范式是以边际分析方法为基本工具、以均衡为核心概念、以效率为规范性目标的法学研究框架。

Concretely speaking, for the analysis paradigm of law and economics the first problem is to apply marginal analysis method to resolve the optimization problems such as personal effect optimization, enterprise profit maximization and government tax maximization. The obtained optimal act congregation of related actors by marginal analysis method is equilibrium that is the core concept of the analysis paradigm of law and economics. The ultimate task of the analysis paradigm of law and economics is to carry on efficiency evaluation on the equilibrium composed of optimal acts of actors, namely to review whether some equilibrium is fit for efficiency standard. From this, it can be seen that the analysis paradigm of law and economics is a law studying frame that takes marginal analysis as tool, takes equilibrium as the main except and takes efficiency as the role goal.
