摘　　要：法经济学分析范式在法经济学理论体系中处于基础性地位。从某种意义上而言,法经济学的发展实际上就是其自身分析范式的持续性革命。科斯以交易成本为最基本的分析工具,架起了新古典经济学与法律之间联系的桥梁,在大大增强了新古典经济学对现实问题解释力的同时,也为法经济学的研究提供了可能。而波斯纳则在继承科斯法经济学分析范式的同时,另辟蹊径,运用科斯提出的交易成本理论及其衍生的效率工具来分析法律规则背后的经济逻辑,为法经济学的进一步发展拓宽了理论的空间,由此形成了法经济学下的经济的法律分析和法律的经济分析的不同研究路径,从而最终导致法经济学分析范式的分野。It is the analyzing paradigm of law and economics that exists in the basic place,which the development of law and economics,in the sense,is the revolution of its analyzing paradigm.Coase links Neo-economics and law with the transaction cost,which it reinforces the explanation power of Neo-economics upon the reality,meanwhile provides the possibility for the study of law and economics.However,Posner develops a new style that uses the transaction cost tool advanced by Coase and efficiency deduced from the former to analyze the economic logic included in the rules of law in the accordance with Coase＇s analyzing paradigm of law and economics,which widens the theoretical space for the development of law and economics.So it forms two different study ways that are the law analysis of economics and the economic analysis of law finally and causes the division of analyzing paradigm of law and economics.
