运用非合作博弈方法,建立带参数的替代型公共品提供博弈,分析公共品自愿提供过程中,政府策略选择对促进个体行为的影响,以及贡献者的策略选择问题,并进一步讨论公共品自愿提供的激励机制。通过构造公共品提供的合作博弈,得到其核心与公共品提供的林达尔配置统一,因此是满足个体理性和集体理性的配置方式。 This paper uses the non-cooperative game method to establish the game of alternative public goods with parameters, analyzes the influence of government strategy selection on promoting individual behavior and the strategy selection of contributors in the voluntary supply of public goods, and further discusses the voluntary supply of public goods Incentive mechanism. By constructing a cooperative game provided by public goods, we can get the unified configuration of Lindal provided by its core and public goods, and therefore it is a way to meet the individual rationality and collective rationality.
