The amendment of the Legislation Law in 2015 expanded the scope of the subject of administrative legislative power in China, extending the local legislative power that was originally exclusive to Larger Cities to all Cities with Districts, which meets the actual needs of local development in China. At the same time, as empowering local governments, "limitation clauses" have been added to the exercise of local legislative power, limiting the legislative matters of local government regulations to the "three major matters". Empirical evidence shows that this "although relaxed, limited" system has led to many difficulties for local governments in exercising local legislative power, such as low legislative enthusiasm and the exercise of legislative power deviating from local legislative needs. To overcome this dilemma, it is necessary to return to the starting point and analyze the correlation between the initial "purpose of empowerment" and "means of limiting power". We should try to shift our perspective from legislative theory to legal interpretation theory, and clarify the administrative legislative authority of Cities with Districts by reasonably expanding the legal interpretation of the "three major issues" and "etc." listed. In response to the practical challenges of local governance and the legitimate rights and interests of the people, we aim to achieve a seamless connection between legislation and reform decisions, and promote the modernization of the national governance system and urban governance capabilities.
