从“科斯定理”到“波斯纳定理”:防御商标制度构建的法经济学解读

From"Coase Theorem"to"Posner Theorem":Legal and Economic Interpretation of the Construction of Defensive Trademark System

长期以来,学界对于防御商标制度构建的讨论始终停留在法教义学的理论研究,似乎忽视了对于防御商标制度引鉴的法经济学思考。现有商标立法对驰名商标的制度保护显露疲态,囿于立法缺失导致防御商标制度处于一种法律与现实模糊不清的存续状态。御商标制度的引入与否根本在于处理好防御商标制度的权利配置及其效益问题。从“科斯定理”到“波斯纳定理”的法经济学分析能够为理解防御商标制度的经济学价值提供新的视角。在制度实现路径上应当从模式观、体系观、权利观三个层面创建本土化的防御商标制度。

For a long time,the academic circles'discussion on the construction of the defensive trademark system has always remained at the theoretical study of legal doctrine,which seems to ignore the legal and economic thinking of the defensive trademark system.Existing trademark legislation has shown weakness in the protection of well-known trademarks,and the lack of legislation has led to the existence of a state of ambiguity between the law and the reality of the defense trademark system.Whether the imperial trademark system is introduced or not lies in dealing with the right allocation and benefits of the defensive trademark system.Law and economic analysis from"Coase Theorem"to"Posner Theorem"can provide a new perspective for understanding the economic value of the defensive trademark system.
