This study aimed to examine the incentive effects of government subsidy policies to promote the development of green buildings. In particular, four different designs of subsidy policy were investigated: a) subsidies paid to developers alone, b) subsidies paid to consumers alone, c) subsidies paid to both, and d) no subsidy. Two-stage models involving developers, consumers, and the government were constructed to examine the effects of the different subsidy policies. In the models, developers supply and sell buildings with different green effort levels; consumers purchase the buildings according to their green preferences. The results of the numerical analysis indicated that the subsidies were a positive incentive for the development of green buildings. Simultaneously subsidizing both developers and consumers resulted in the greatest profits for developers and the highest social welfare. The incentive effect of subsidies on consumers was superior to that of subsidies on developers, revealing the increasingly important role of consumer behavior in the green building market. Furthermore, the incentive effects of the four subsidy policies were significantly enhanced with the improvement of consumers' green preferences and the unit potential benefit for developers.

本研究旨在考察政府补贴政策对绿色建筑发展的激励作用。特别是，研究了四种不同设计的补贴政策：a）仅向开发商支付的补贴，b）仅向消费者支付的补贴，c）对双方支付的补贴，以及d）无补贴。构建了包括开发商，消费者和政府在内的两阶段模型，以检验不同补贴政策的效果。在模型中，开发商提供和出售具有不同绿色努力水平的建筑物。消费者根据自己的绿色喜好购买建筑物。数值分析结果表明，补贴是绿色建筑发展的积极动力。同时补贴开发商和消费者，为开发商带来了最大的利益，并带来了最高的社会福利。补贴对消费者的激励效果优于补贴对开发商的激励效果，这表明消费者行为在绿色建筑市场中的作用日益重要。此外，随着消费者的绿色偏好和开发商潜在的单位收益的改善，四项补贴政策的激励效果得到了显着增强。
