空白票据是随着经济发展和信用制度的发达而产生的,由于它与票据的文义性、要式性等基本法律特征相违背,因而各国立法起初并不承认空白票据的效力。但随着空白票据在日常经济交往中的大量存在,因而有必要对其进行立法上的规制。本文从空白票据的概念、构成要件、效力和失票救济制度四个方面对空白票据进行了粗浅的探讨。 Blank notes originated with the development of economy and the credit system. Due to its inconsistency with the basic legal features such as the textuality and the formality of the notes, national legislation did not initially recognize the validity of blank notes. However, with the large number of blank notes in daily economic exchanges, it is necessary to regulate them by legislation. In this paper, we discuss the blank paper from the following four aspects: the concept of the blank paper, the constitutional requirements, the effectiveness and the remedy of losing the money.
