摘　　要：本文在凯恩斯投资乘数理论的基础上,将投资乘数的影响因素由边际消费倾向、边际税率和边际进口倾向三个因素扩展到包含企业边际投资倾向和边际货币需求率在内的五个因素。首先推导了边际消费倾向、边际税率、边际进口倾向对投资乘数的影响大小及方向;然后从理论上分析了企业边际投资倾向和边际货币需求率对投资乘数产生影响的原因及传导机理;最后推导了包含五个影响因素的投资乘数公式,进而得出企业边际投资倾向和边际货币需求率影响投资乘数的大小及影响方向。On the basis of the Investment Multiplier Theory, this paper will expand the factors affecting the investment multiplier from the original three （the marginal propensity to consume, the marginal tax rate, the marginal propensity to import） to five including the marginal propensity to invest and the marginal rate of monetary demand. First, this paper will deduce the magnitude and the direction of influences on the investment multiplier by the marginal propensity to consume, the marginal tax rate, the marginal propensity to import. Then, the paper will theoretically analyze the causes and conduction mechanism of influences on the investment multiplier by the marginal propensity to invest and the marginal rate of monetary demand. At last, this paper will deduce the investment multiplier formula contains these five factors, thus finding out the magnitude and the direction of influences on the investment multiplier by the marginal propensity to invest and the marginal rate of monetary demand.
