装配式住宅和现浇住宅是开发商和客户选择的两种选择。政府作为政策制定者，制定激励政策，鼓励开发商和客户选择装配式住宅。本文旨在通过演化博弈模型和仿真，对补贴机制进行分析，从理论上确定补贴的范围、数量和终止时间。在博弈模型中，政府补贴影响了开发商和客户在决策过程中的互动。调查结果如下：1）开发商住房补贴可以降低房价，而客户住房补贴可以提高房价; 2）政府应在开发初期给予开发商较大的补贴金额，之后给予客户较小的补贴金额; 3）政府应根据开发商和客户选择装配式住房的比例确定结束时间; 4）较高的预制比例并不一定能促进预制房屋的发展，存在一个最佳的生产规模，创造最佳的发展局面。实证分析表明，该模型可以帮助政府在预算范围内制定合理、最优的补贴政策，以刺激开发商和消费者。
Prefabricated housing and cast-in-site housing are two alternatives for selection by developers and customers. The government, as the policy maker, creates incentive policies to encourage developers and customers to choose prefabricated housing. This paper aims to analyze the subsidy mechanism to theoretically confirm the subsidies’ scopes, amounts and end times through an evolutionary game model and simulation. In the game model, government subsidies affect the interactions between developers and customers in the decision-making process. The findings are as follows: 1) The developer housing subsidy can lower the housing price, while the customer housing subsidy can increase the price; 2) The government should first offer the developers a larger subsidy amount during the early development stage and then offer the customers a smaller subsidy amount later; 3) The government should determine the end time based on the proportion of developers and customers who choose prefabricated housing; 4) A higher prefabrication ratio may not always improve the development of prefabricated housing, and there is an optimal production scale that creates the best development situation. The empirical analysis shows that this model can help the government develop reasonable and optimal subsidy policies within the limit of budget to stimulate developers and customers.
