预期违约制度虽属英美法系的一项制度,但在我国《合同法》中也引进了该项规定,但是我们的引进仍存在着一定的问题。由于篇幅的限制,本文仅在对英美法系明示预期违约的一般规则研究的基础上,对预期违约制度与我国相关制度加以比较,特别是明示预期违约与拒绝履行的对比,同时对明示预期违约行为的法律后果进行了阐述。 Although the expected system of breach of contract is a system of Anglo-American legal system, it has also been introduced in China’s “Contract Law”, but there are still some problems in our introduction. Due to space limitations, this article only compares the expected system of breach of contract with the relevant systems in our country based on the study of the general rule of anticipatory breach of contract in Anglo-American law system. In particular, it contrasts explicitly with expected default and refusal to perform, meanwhile, The legal consequences of conduct are described.
