摘要： 同时履行抗辩权，又称为给付拒绝权，其规范目的在于向对方施加压力、担保自己债权的实现。双务合同中，一方当事人负有固有的先给付义务的情况下，即没有同时履行抗辩权适用之余地。基于双务合同，存在相互关系的给付义务，若存续、到期并未被提出，债务人即可行使同时履行抗辩权，拒绝自己的给付。在实体法上，同时履行抗辩权的法律效果为拒绝给付权，同时履行抗辩权可以排除债务人迟延；在程序法上，同时履行抗辩权是须主张的抗辩，判决内容为同时履行判决，在债务人陷于受领迟延的情况下，债权人可以根据此限制判决，不履行(清偿)其所负担的给付，而通过强制执行方式实现其请求权。

Abstract: The right of concurrent performing counterplea,  in other words,  the right of defense to reject the demand,  aims to give pressure to the counterparty and make sure the realization of one's own obligations.  In a bilateral contract,  when a party has the obligations to fulfill his duties first,  there is no space for the application of the right of concurrent performing counterplea.  However,  when the following conditions are satisfied,  including two associated payment duties,  the claims being existing,  becoming due and not being submitted yet,  a right of concurrent performing counterplea has its role.  In the substantive law,  the legal effectiveness of the right of concurrent performing counterplea is the same as the right to reject the demand.  Besides,  the right of concurrent performing counterplea could exclude the delay of the debtor. In the procedural law,  it should be submitted before the judge,  otherwise the judge has no duties to review whether the right exists or not;  What is more,  the result of the judgement is to order both parties to fulfill their obligations simultaneouslyWhen the debtor falls in a delay of acceptance,  the creditor shall fulfil his obligations by compulsory execution according to the judgement.
