“双碳”目标下政府不同补贴策略对绿色建筑市场的影响研究

Research on the Impact of Different Government Subsidy Strategies on the Green Building Market under the Dual Carbon Goals

通过构建消费者效用和开发商利润函数,分析了无补贴、开发商成本补贴与消费者价格补贴3种策略下的消费者绿色偏好等因素对绿色建筑市场的影响,并结合数值仿真,对消费者和开发商决策行为进行了分析。结果表明:消费者绿色偏好程度的提高对于促进建筑绿色发展具有正向激励作用;当补贴力度较低时,3种补贴策略对绿色建筑市场的影响不大,但随着补贴力度的增强,消费者价格补贴策略可以更大程度地提高对于绿色建筑的需求和绿色建筑开发商的收益。

By constructing consumer utility and developer profit functions,the impact of consumer green preferences and other factors on the green building market under the three strategies of no subsidy,developer cost subsidy and consumers′price subsidy is analyzed,and the decision-making behavior of consumers and developers is analyzed in combination with numerical simulation.The results show that the improvement of consumers′green preferences has a positive incentive effect on promoting the green development of buildings.When subsidies are low,the three subsidy strategies have little impact on the green building market,But,with the increase of subsidies,the consumers′price subsidy strategy can improve the demand for green buildings and the benefits of green building developers to a greater extent.
