科斯与波斯纳均为法律经济学说史上的标志性人物。无论从历史的还是逻辑的角度考察,法律经济学均是沿着从科斯到波斯纳的轨迹展开的。但因后者将前者含有“局限条件下合约选择”的科斯定理本源思想,简化为价高者得、赢者通吃的权利优化配置进路,并对我国法律人产生广泛而深刻的影响,其正当性和解释力也备受诟病,故很有必要提倡从波斯纳到科斯的回归,以澄清法律经济学理论的本来面目,进而更好地发挥其在解释中国法律问题上的积极作用。 Both Kos and Posner are iconic figures in the history of law and economics. Whether viewed historically or logically, legal economics follows the path from Kos to Posner. However, the latter simplifies the fundamental principle of Coase Theorem containing “the contract choice under limited conditions” to the optimal allocation of rights for the highest bidder and the winner, and has extensive and profound legal rights for our legal persons Influence, its legitimacy and explanatory power has also been much criticized, it is necessary to promote the return from Posner to Kos to clarify the true nature of legal economics theory, and thus better play its positive role in the interpretation of Chinese law .
