通过对各个法律效率评价标准进行评述,提出法律成本收益分析法是测算法律效率的可操作的有效标准。在理论上将法律成本进一步分解为法律制定成本与法律实施成本,其中,法律制定成本属于沉没成本,不应纳入法律效率的评价模型之中;法律实施成本包括脱序成本、第二类摩擦成本及失益成本。对于法律收益,提出以法律目标为指引的确定方法。本文同时给出每一类法律成本及收益的具体测度方案,并构建出法律效率量化的理论框架,最终通过森林采伐限额管理制度验证了该理论框架的可操作性,从而使得法律效率评价成为可能。
The paper suggests that the legal cost-benefit analysis is an operable and effective way for calculating the efficiency of law through a review of evaluation criteria of legal efficiency. Legal cost is divided into law making cost and law enforcement cost by theoretical analysis in the paper,among which law making cost should not be included in the law evaluation model,as the cost belongs to sunk cost,and the law enforcement cost includes de-order cost,friction cost and loses. The range of legal benefit should be defined by the object of the law. The paper also proposes the methods for quantifying the costs and benefits,meanwhile,theoretical framework of evaluation criteria of legal efficiency has been presented. Finally,we apply the theoretical framework to the analysis of the efficiency of forest logging quota management system.
