论效率、公平正义理念的目标均衡与价值选择——兼论法经济学的价值观

Objection Equilibrium and Value Choice of Efficiency and Social Justice Idea

效率、社会公平正义作为人类社会的基本理念和基本行为准则,是法经济学的核心价值追求,也是和谐社会的内在要求与本质内容。坚持效率观与伦理观相结合的价值判断与选择并在不同领域和特定环境下进行研究才能解决公平正义与效率的均衡问题。在社会经济资源约束条件下通过建立一个拓展的社会福利函数整合了法经济学的多元价值目标并构建一个效率与公平的均衡分析框架模型,对其均衡实现过程进行分析,结果表明:效率与公平作为社会经济发展追求的两大价值目标和基本尺度,二者之间关系是一种动态过程,其关系异化的根源在于市场扭曲与政府功能错位;效率与公平的目标均衡实现最终要靠市场与政府的功能准确定位与价值选择,通过权衡与协调二者的作用边界来实现。

As the basic idea and code of conduct in human society, efficiency and social justice is the core value pursuit of law and economics, also the inner requirement and essential content of harmonious society. Equilibrium problems with efficiency and social justice can be solved by adhering to value choice of the combination of efficiency view and ethics in different fields and specific environment. This paper constructs an equilibrium analysis model by an extended social welfare function to integrate the multi-value goals of law and economics under constraint of social economic resources, and analyzes its equilibri- um realization. The results show that efficiency and social justice, as the basic value goals and scale of society economy development, is a dynamic interaction process. The alienation origin of the two lies in market distortion and dislocation of government function, the objection equilibrium realization of efficiency and social justice depends on the function location and value choice of market and government, namely trade off and coordination of the function boundary between the two.
