To form an effective framework of the non-profit organization，it is necessary for us to reconstruct the cognition of the connotation and function within the non-profit organization，namely solving the problems of which “why it might to be possible” and “how it can be done” for the nonprofit organization. Peter Frumkin divided such function into four parts by constructing a two-dimensional matrix analysis model，including demand guide-instrumental（social service supply）、supply guide-instrumental（social business）、demand guide-expressive（citizen and political participation）and supply guide-expressive（value and mission）. However，in practice，it is extremely possible that the predicament of non-profit organizations is able to be triggered by the excessive enhancement of any function. The solution Peter Frumkin proposed is the strategy of “the way of balance”，which improved and supplemented the functions of four types of non-profit organizations. Starting from the perspective of Peter Frumkin，we can get the following inspirations：Social organizations need different development models；it not only focuses on the subject-oriented dimension and the rational dimension，but also pays attention on other dimensions of the development of non-profit organizations；Put great emphasis on the institutional environment in which non-profit organizations operate；Constantly strengthen the function of expression of non-profit organizations.
