预期违约与不安抗辩：融合抑或取代

Anticipatory Breach of Contract and Einrede der Vnsicherkeit -Combination or Replacement

对'期前违约'行为,英美法系通过预期违约制度,大陆法系通过不安抗辩权制度来救济,两制度的差异带来了两制度的融合.然而由于不安抗辩制度本身所存在的先天性的制度缺陷,融合或改造的本身--德国法上的司法补充或中国合同法的立法扩大,都不能使其全面而充分的保护债权人利益,因此,最终的也是最好的选择应为融合后的预期违约制度.

System of conation law remedies 'breach of contract before the period of performance' through the institution of anticipatory breach of contract, while system of civil law remedies it through institution of 'Einrede der Vnsicherkeit'. The difference between the two institutions leads to the combination. But because there are some originally institutional flaws in 'Einrede der Vnsicherkeit',the facts of combination and reform-the judicial supplement in German law or the legislative enlargement in Contract Law of China, can't protect interests of creditors fully and comprehensively. So the final and also the best choice should be the institution of anticipatory breach of contract.
