Since reform and opening-up，with ever deepening development in economic reform，reform of administrative system has pushed forward gradually. From 1982 to 2003，China experienced 5 major institutional restructuring，but the result was confined within the circle of “streamlining—swelling—re-streamlining”. Since the beginning of the 21st Century，China has accelerated its reform of administrative system and the goal and approach of the reform have evolved in the transformation from the relatively single purpose of “streamlining，unifying and efficiency” into “function-changing，relation-balancing，structure-optimizing and efficiency-enhancing”，which places more emphasis on the triple relations among “decision-making，implementation and oversight”. At the same time，the connotation of the reform has also extended from the one that focuses on the setup and restructuring of governmental organs to the one that covers the relevant areas of laws and regulations as well as institutional construction. Thus，reform of administrative system gradually becomes a comprehensive and systematic reform.
