Competitive Behavior of Developers' Development Scale in the Assembled Construction Market: An Analysis Based on Game Theory

摘要

The paper constructs the oligopoly models of assembled building developers based on Cournot model and Stackelberg model of development scale competition. Based on the comparison of the profit of the regional assembled building market, which is obvious in product homogeneity and multi oligopoly, a game analysis is carried out for the development pattern of assembled building developers. On the basis of the above models, we get the equilibrium solution of developers' Cournot competition and the sub game refining Nash equilibrium solution of the developers' Stackelberg competition respectively. Based on the different N values, we compare the development scale, the development income and the market price of the two competitive modes. Combining with the above game equilibrium, this paper makes a concrete analysis of the actual situation of the competition of assembled building developers in China.
