Study on game among government and construction units about green engineering

Green engineering is certain require of building resource conserving and environment friendly society, it is also the guarantee for sustainable development of construction industry. However, for saving investment and reducing project cost, construction units, as investors, are usually reluctant to implement green engineering. So it is necessary for government to take administrative means to supervise construction units. In this paper, three static game models for green engineering between the government and construction units are established based on hypotheses, and equilibrium strategies are deduced respectively. According to the equilibrium strategies, the government couldn´t promote construction units to take green engineering only with direct rewards. But if the government gives the public an incentive to supervise construction units, and strengthen the punishment dynamics, the green engineering can be promoted effectively.
