摘　　要：在投入产出模型里引入凯恩斯乘数理论,建立能够计算结构化乘数的投入产出乘数模型,是近年来投入产出领域探讨较多的一个问题。从前提假设、乘数效应的传导机制和最终推导结果等方面对凯恩斯乘数模型和投入产出乘数模型进行比较,指出建立投入产出乘数模型将凯恩斯乘数进行结构化处理,应该从放宽前提假设条件入手,并以引入列向旁侧效应为例对原模型进行了扩展。How to construct I - O multiplier model so as to compute structural multiplier is a hot topic recently which many experts ＂analyze with various methods. Through examining the hypothesis of Keynesian multiplier theory , the transfer mechanism of multiplier effect and the outcome of mathematical models, the author compares I - O multiplier model with Keynesian multiplier model. In conclusion, the author points out the right way to deduce structural multiplier is to loosen the strict hypothesis, which is exemplified by extending the prior models with taking army effect into account.
