我国效率违约立法缺陷及完善

Flaws and improvement of the legislation of efficiency default

效率违约是经济分析法学派提出的一种新的违约理论,是指违约方从违约中获得的利益大于他向非违约方做出履行的期待利益;或者指当履行的成本超过各方所获得利益时,违约比履行更有效。在这一理论下,合同法已由原来的“单纯惩恶扬善的工具”变为一种“合理划分商业风险的法律手段”。

The efficiency default is a new default theory put forward by economic analysis school. It means the defaulter can get greater benefits from defaults than those he may get in fulfilling; or when the cost to fulfill is exceeding the benefits of all parties, default is mere effective than fulfilling. In this theory, Contract Law has been changed from the ＂pure tool of punishing evil and promoting good＂ into a ＂legal means to rationally divide the business risks.＂
