本文通过构建两个地区之间的非合作博弈均衡模型,从理论上探讨同时提供和序贯提供两种地区间外溢性公共品的二阶段或三阶段动态博弈变化过程,并在此基础上分析直接供给承诺与以匹配率为主要方式的间接供给承诺的相互关系。研究表明,两个地区完全承诺直接供给和匹配率间接供给下的同时提供模型是帕累托最优的;只有一个地区进行匹配率间接承诺的模型结果具有不确定性,但是做出匹配率承诺的地区的福利对比没有承诺的地区来说有所增进;序贯提供两种外溢性公共品时,总供给量要低于同时提供模型的总供给量,两种外溢性公共品的供给量具有关联性,匹配率的作用不显著。最后,论文对模型结果进行了比较分析并提出相关政策建议。
In this paper, through the construction of a non-cooperative game equilibrium model between two regions, this paper theoretically explores the two-stage or three-stage dynamic game process of providing and sequentially providing two inter-regional public goods, and on this basis, The relationship between the direct supply commitment and the indirect supply commitment based on matching rate. The research shows that Pareto Optimality is the best Pareto model in which both regions commit their full commitment to the direct supply and the model of simultaneous supply under the indirect supply of matching rate. Only one region has an uncertainty about the result of the indirect commitment matching rate, but the match rate commitment Compared with the unprofitable areas of the region; the sequential supply of two kinds of spillover public goods is lower than the total supply of the model at the same time. The supply of two kinds of spilled public goods has The effect of matching and matching rate is not significant. Finally, the thesis makes a comparative analysis of the model results and puts forward some relevant policy suggestions.
