Abstract: With the diffusion of platform technology, platform government is becoming a new government pattern and surpasses traditional bureaucratic system. Platform government is a structured and compound organizational form that integrates technical elements, governance functions and bureaucratic organization. It takes “overlapping-layer nesting” as organizational structure and “bureaucracy-oriented subject and platform-guided instrument” as organizational form, achieving response to personalized, diversified and complex social appeals through “three-in-one” operation mechanism of “service-based governance network fore-end” “technology-based resource sharing middle-end” and “institution-based power flow back-end”. The emergence and operation of platform government is one kind of strategic organizational innovation which embodies loose coupling of “subject” and “instrument”. In essence, this strategic organizational structure presents the pursuit of allocative efficiency of institutional nesting periodically. Therefore, in order to realize in-depth integration of platform technology and bureaucratic organization, prolong operational efficiency from the time dimension and realize adaptive efficiency of combining “temporary need” and “long-term method”, seeking solutions from tangled institutional system construction is necessary.
