摘要： 均衡性原则在适用时存在主观裁量滥用、客观利益衡量不足和“结果导向性”分析等弊端，有必要推进均衡性原则的具体化。目前具体化均衡性原则的尝试主要可分为两种模式：一种是从权衡者角度出发的数学计算模式；另一种是从当事人角度出发的事实问题商谈模式。均衡性原则的本质为目的必要性分析，其功能在于保障权利不被过度侵害和促进社会整体福利。为了尽可能地消除均衡性判断的非理性，应当以权衡者和当事人为共同视角，构建出均衡性原则具体化的新模式：通过吸收成本收益分析方法，并借助于均衡性判断公式，计算出某个最小损害性手段所促进的公益与所造成的损害的比例值，然后再根据均衡性判断法则，具体权衡该最小损害性手段是否具有均衡性。

Abstract: Proportionality in the Narrower Sense can cause the abuse of discretion, inadequate measure of benefits and results-oriented analysis, so we should make proportionality in the narrower sense more specific to limit balancing.  The concretization of proportionality in the narrower sense can be mainly divided into two modes. One is the mathematical model from the perspective of the balancers, the other one is the discourse mode from the perspective of the parties. The essence of the principle of proportionality in the narrow sense is the judgment of the necessity of purpose. Its functions are to protect the human rights and to make sure that the whole social welfare is promoted. In order to eliminate the irrationality of proportionality in the narrower sense as much as possible, we should construct a new concretization mode from the common perspective of the balancers and the parties. We should use cost benefit analysis and the formula of the equilibrium to calculate the proportional value of the less restrictive mean which can cause damage and promote interest, and then balance whether the less restrictive mean is comply with proportionality in the narrow sense according to the formula of the equilibrium.
