宏观经济学是了解经济学的基本维度之一，通过学习宏观经济学模型可以了解国民收入决定理论、消费函数理论、投资理论、货币理论等理论，从而学习经济政策的目标、工具以及经济政策机制，对政策效应进行检验。货币政策是中央银行为实现特定的经济目标而采用的各种控制和调节货币供应量和信用量的方针，本课题将通过宏观经济学模型来评估这一政策手段。
财政政策一般是指政府通过改变财政收入和支出来影响社会总需求，以便影响就业和国民收入的政策。财政政策的目标是要实现充分就业、经济稳定增长、物价稳定，同样也是社会和经济发展的综合目标。现代宏观经济学研究的主要目标就是尽可能全面地理解经济的运行方式，在特定的政策和可能引起动荡的各种需求、供给的冲击下，它是如何作出反应的。宏观经济理论包括：国民收入决定理论、消费函数理论、投资理论、货币理论、失业与通货膨胀理论、经济周期理论、经济增长理论、开发经济理论宏观经济政策包括经济政策目标、经济政策工具、经济政策机制即经济政策工具如何达到既定的目标、经济政策效应与运用。
Macroeconomics is one of the basic dimensions to understand economics. By learning macroeconomics models, we can understand national income determination theory, consumption function theory, investment theory, monetary theory and other theories, so as to learn the objectives, tools and mechanisms of economic policies, and test the effects of policies. Monetary policy is a kind of policy adopted by the central bank to control and regulate money supply and credit quantity in order to achieve specific economic goals. This topic will evaluate this policy means by macro-economic model.
Fiscal policy generally refers to the policy that the government affects the aggregate social demand by changing fiscal revenue and expenditure, so as to eventually affect employment and national income. The goal of fiscal policy is to achieve full employment, steady economic growth and price stability, which is also the comprehensive goal of social and economic development. The main goal of modern macroeconomic research is to understand as fully as possible how the economy works, how it responds to particular policies and to the kinds of demand and supply shocks that can cause turbulence. Macroeconomic theories include: national income decision theory, consumption function theory, investment theory, monetary theory, theory of unemployment and inflation, economic cycle theory, the theory of economic growth and development of economic theory of macroeconomic policy including economic policy goals, economic policy, economic policy mechanism, namely economic policy tools how to achieve the established target, economic policy effect and application.
