【Abstract】 According to the decisive patterns of the private supply, public goods can be divided into three kinds: the replaceable, the complementary and the containable. In this paper, we develop a model to analyze the strategic behavior of the participators by means of game theory. Then we draw the reaction curve and find the solution of Nash equilibrium. At last, we analyze the rationalization of the result and propose some advice for improvement.更多还原
