   Local government regulations refer to the general term for normative documents such as provisions, measures, detailed rules, and regulations that are universally applicable within the administrative region. These are formulated by the people's governments of provinces, autonomous regions, municipalities directly under the central government, and larger cities in accordance with laws and regulations through prescribed procedures. In China's administrative activities, regulations serve as an important supplementary form to laws and regulations.

   There are fundamental differences between local government regulations and local legislation:

    1. Different promulgating authorities;
    1. Different levels of authority and social effectiveness. Local government regulations have lower legal effect than local legislation, with local legislation being valid within the respective province (city) jurisdiction and subordinate to the Constitution, national laws, administrative regulations, and local legislation of the province/autonomous region.

   The China Local Government Regulations Database developed by CnOpenData originates from official websites and government gazettes of people's governments at provincial, autonomous regional, municipal, districted city, and autonomous prefecture levels, containing fields such as main title (主标题), regulation type (规章类型), enacting authority (制定机关), and full text content (正文内容).
