Abstract: Focused on the "Streamline Administration, Delegate Powers, Improve Regulation and Services" (DPIROS) reform, this paper examines the fundamentals and implications of the DPIROS reform which includes streamlining administration, delegating powers, and optimizing services. The current state and issues associated with the type approval system for measuring instruments in China are systematically reviewed. By analyzing the program management models for type evaluations in the European Union and the United States, an initial type approval reform advancement scheme for China's measuring instruments is proposed. This takes into account DPIROS measures, the reform entities involved, and the specific issues addressed. Concrete recommendations for improvement are also offered. The suggested reforms emphasize the need for legal and standard operations in the type approval system. This includes further clarifying the scope of the catalog of compulsorily managed measuring instruments, enhancing the scientific rationality of type evaluation guidelines, and coordinating unified technical requirements for type evaluation. In the manufacturing sector, efforts should be made to assist manufacturers of measuring instruments in improving their quality assurance systems, while clarifying their responsibilities and obligations. In the regulatory realm, it's recommended to strengthen follow-up regulatory measures, explore diversified supervisory methods such as targeted inspections based on risk grading, and establish a credit rating system for manufacturers of measuring instruments. The paper also advocates the development of a unified national information service platform to enhance online government services, increase information transparency, facilitate enterprise reporting, querying, and social supervision.
