就民族区域自治地方立法权行使的现状来看,自治区单行条例缺失的现象不容忽视。综合我国现有法律体系的相关内容,并结合单行条例自身的特点,其主要原因至少有以下几个方面:其一,上位法界分不明。其二,上级立法机关监督缺位。其三,立法主体的“理性规避”。其四,立法的直接法律依据缺失。 As for the status quo of exercising the legislative power in the ethnic autonomous areas, the phenomenon of the absence of a single bank in the autonomous region can not be ignored. Based on the relevant contents of the existing legal system in our country and the characteristics of the one-way ordinance, the main reasons are at least the following: First, the division of the upper-level law is not clear. Second, the absence of oversight by the higher legislature. Third, the legislative body “rational avoidance ”. Fourth, there is a lack of direct legal basis for legislation.
