摘要： 确认之诉成为基本的诉讼类型之一，其根基在于确认利益。按照确认利益的要求，确认之诉相对于给付之诉具有辅助性，而给付之诉则处于优先地位。由此引发了确认之诉与给付之诉之间的紧张关系。借助诉讼标的理论只能在有限的范围内解决这种紧张关系，要使这个问题获得全面的解决，更需要精细的程序制度设计。对此，理论界和实务界给出了多种解决方案，从中止诉讼、合并审理到终止确认之诉等。这些解决方案之间的综合协调，需要审慎对待，因为无论选取何种方案，反过来又要以此为起点重新审视既有的诉讼标的理论和合并审理等制度。

Abstract: Declaratory action becomes completely a fundamental type of litigations because of the interest in declaratory relief, in other words, the necessity of the declaratory relief.In return, however, interest in declaratory relief becomes to be the weakness of the declaratory action, and makes it subsidiary to the action for performance.The latter is superior to the former.All of this results in the tension between the both types of action and therefore the independency of the declaratory action is undermined by the action for performance.This problem can only partially be resolved through the res judicata.There are several resolution plans, such as suspension of the secondly filed suit, joint trial of both actions, termination of the first action etc.

Key words: Declaratory Action, Parallel Litigation, Interest in Declaratory Relief
