Abstract: The source of effectiveness of intra-Party regulations is a fundamental theoretical issue in the study of intra-Party regulations.Clarifying the source of their effectiveness is of great significance for improving the quality of intra-Party regulatory texts and promoting their comprehensive implementation.As components of the socialist rule-of-law system with Chinese characteristics,intra-Party regulations and national laws share certain common elements in terms of the sources of their effectiveness,but they also have distinct differences.On the one hand,the exploration of the sources of legal effectiveness by different schools of jurisprudence throughout history provides valuable theoretical resources for understanding the sources of effectiveness of intra-Party regulations;on the other hand,Chinese scholars have developed a certain theoretical foundation regarding the sources of effectiveness of intra-party regulations,offering useful perspectives.However,shortcomings remain,such as over-reliance on theories of national law that fail to fully reflect the unique characteristics of intra-Party regulations,an inability to comprehensively reveal the sources of effectiveness across different historical stages,and simplistic transplantation of foreign theories.To strengthen the theoretical foundation of the sources of effectiveness of intra-Party regulations,it is necessary to draw upon the historical experience of governing the Party through regulations,the justice-oriented nature of intra-Party regulations,Party members' voluntary recognition of these regulations,and the enforcement guarantees backed by Party discipline.These efforts should be guided by the texts of intra-Party regulations,the practice of governing the Party according to rules,the fine traditions of the Communist Party of China,and the requirements of China's rule-of-law construction.
