Exploring the impact of infringement products on authentic products in the dual situation based on economic methods
基于经济学方法的二元情况下的侵权产品对正品的影响探究

摘要

在处理侵权案件的赔偿数额时，权利人的实际损失通常被优先考虑作为计算基础。然而，在我国的司法实践中，以权利人实际损失作为赔偿基准的案例比例较低。一是权利人提供证据的困难或消极性，部分权利人可能无法或不愿意提供这些证据，导致实际损失难以作为赔偿基准。二是司法界普遍认为实际损失难以精确评估。因此，法律从业者更倾向于使用法定赔偿方式，而没有一套较为定量、客观的赔偿确定体系。本文聚焦替代品侵权案件中权利人的实际损失问题，采用交叉价格弹性、供需分析和双重差分方法进行尝试性评估，并从经济与法律两方面分析类似案例，进而提出优化建议。

Abstract

When dealing with compensation amounts in infringement cases, the actual losses of the rights holder are usually given priority consideration as the basis for calculation. However, in China's judicial practice, the proportion of cases where the actual loss of the rights holder is used as the compensation benchmark is relatively low. One is the difficulty or negativity of the rights holders in providing evidence, and some rights holders may be unable or unwilling to provide such evidence, resulting in actual losses that are difficult to use as compensation criteria. Secondly, the judicial community generally believes that actual losses are difficult to accurately evaluate. Therefore, legal practitioners tend to use statutory compensation methods rather than a more quantitative and objective compensation determination system. This article focuses on the actual losses of rights holders in substitute infringement cases, using cross price elasticity, supply and demand analysis, and double difference methods for exploratory evaluation. Similar cases are analyzed from both economic and legal perspectives, and optimization suggestions are proposed.
