结构式乘数及其对凯恩斯主义宏观经济理论的发展

Structural Multiplier and Its Development to Keynesian Macroeconomics

本文通过放松凯恩斯总量乘数模型关于"各部门边际消费倾向c和消费结构ω相同"的隐含假定,建立了结构式凯恩斯乘数模型,并指出结构乘数思想的实质是收入非均衡问题,它可以看作结构主义观点的组成部分,是对新古典传统和凯恩斯思想的重要发展,对发展中国家具有更为重要的政策意义。在扩张性政策的实施中,收入政策和税收政策应向国民收入的短板部门倾斜;财政投资应向乘数效应大、产业链条长、挤出效应小的部门倾斜。

The paper constructed Keynes structural multiplier model through loosing the strict and implicit hypothesis about ＂various departments have the same consumption marginal and structure＂, and pointed out that the essence thought of structural multiplier is the income distribution of non-equilibrium which can be seen as a eomonent of structuralism. Structural multiplier is the important development to Keynesian macroeconomies and neo-classicism, and has important policy implications to developing countries. Structural multiplier has an important practical significance for expansionary fiscal policy implementation to cope with the global economic crisis.
