摘要:同时履行抗辩权是双务合同中履行抗辩权体系的重要组成部分之一，同时也是一项重要的合同法制度，在现代经济社会中，该制度能够更好地解决司法实践问题，化解社会经济矛盾纠纷，促进社会和谐局面。因此，同时履行抗辩权对保障债权、鼓励交易、防范风险、促进市场经济稳定发展具有重要意义。

　　　但是，在司法实践当中该制度却不能与实践相结合地更好的解决司法实务问题，出现了理论与实践相脱节的尴尬局面。不仅不能解决纠纷矛盾，而且更是挑战了法律的尊严性和权威性。为了解决我国同时履行抗辩权制度在司法实践中的问题，我们应该建立统一的同时履行抗辩权制度并赋予其新的内涵，为其灌入新的血液，并同时完善同时履行抗辩权制度的司法救济途径。
