Abstract: De-administration reform is the key to institutional reforms， which involves not only separating the functions of the government from those of institutional organizations， but also breaking administrative conventions and constraints， uplifting institutional confidence and reshaping organizational spirits. De-administration reform is to a larger degree hindered by such barriers as conventional administrative hierarchy， authority submission， humble tool and vulgar mammonism. It is suggested that a cultural analysis and diagnosis of what lies at the core of institutional reforms， in combination with subtle cultural promotion and rigid administrative system reform， should exert great impact on the institutional de-administration reform.

Key words: public institution, de-administration, cultural analysis, cultural synergy
