摘　　要：主流宏观经济学中,政府被视为一个仁慈的"社会计划者"或者直接退化为一组政策规则方程。这种简化忽视了政府作为经济决策主体的行为特征,以及政府策略性互动对于宏观经济均衡结果的影响。本文提出了一个嵌套动态一般均衡模型的多政府决策行为理论框架,归纳了四类政府间关系结构,讨论了四类结构下政府决策行为机制与策略互动行为的可能性,分析了一般均衡结果的基本特征,从而为在宏观经济模型中多政府决策行为的内生化提供了一个统一的研究框架。In the mainstream macroeconomic research,government is either treated as a benevolent social planner or replaced by reduced-form policy rules.This simplified approach ignores the fact that the government has its preference and constraints,and policy coordination among governments could have a significant impact on the equilibrium outcome.In this study,we aim to incorporate the behavior of government,at either national or local level,into a standard dynamic stochastic general equilibrium(DSGE)framework.We categorize the structure of governments into four different types,discuss the decision-making process and strategic behavior of governments,analyze the characteristics of equilibrium outcome,and propose a unified approach to endogenize the government behaviors in a standard macroeconomic model.
