商业秘密侵权实际损失厘定的经济分析

Economic Analysis on Determining Actual Loss of Trade Secret Infringement

有关商业秘密侵权损害赔偿数额的认定一直以来都是理论界和实务界的一大难题。通过构建双寡头竞争古诺模型,分析古诺均衡下的市场价格与产量,借助数理经济分析,将其与反事实状态下的垄断情形进行对比,构建同质化情景下商业秘密侵权实际损失模型,进而将其扩展到多名竞争者情况下,并分三种情形展开讨论。在产品同质化情景下,双寡头条件的商业秘密权利人实际损失模型涉及商业秘密产品的保留价格、边际成本、需求弹性三个参数;多名竞争者条件的实际损失模型中增加了竞争者数量参数。产品同质化情境的双寡头条件下,商业秘密权利人的实际损失大于侵权企业的侵权获利;当存在多名竞争者时,结论具有多样性。

The determination of the amount of damages for the infringement of trade secrets has always been a big problem in the theoretical and practical circles.By constructing the Cournot model of duopoly competition,this paper analyzes the market price and output under the Cournot equilibrium,compares them with the monopoly situ⁃ation under the counterfactual state with the help of mathematical economic analysis,and builds the actual loss model of trade secret infringement under the homogenous scenario,and then extends it to the case of multiple com⁃petitors,and discusses it in three cases.In the case of product homogeneity,the actual loss model of trade secret right holder under duopoly condition involves three parameters:reserve price,marginal cost and demand elastici⁃ty;The number of competitors parameter is added to the actual loss model of multiple competitors condition.Under the duopoly condition of product homogeneity,the actual loss of the trade secret right holder is greater than the in⁃fringement profit of the infringing enterprise.When there are multiple competitors,the conclusions are diverse.
