摘　　要：企业的R＆D投资活动习惯上被分为需求创造型创新(DCI)和成本节约型创新(CRI),一方面在现实中DCI广泛存在,而另一方面学术研究仅在CRI上取得丰硕成果,如果能够证实两种创新的模型存在一致性,则对CPI的研究成果的推广具有重要现实意义。本文从Levin和Reiss的DCI模型出发,进行变换推理,得到包含外溢性的CRI模型,从而证明两者在产业组织经济分析的本质上是一致的。R&D is generally classified as demandcreating and costreducing innovations. The former group is generally exists in reality, yet most researches is limited within the latter group and exciting findings appeared one after another. If the models that studying different group of R&D can be verified to be consistent with each other, its helpful to extend the important findings to demandcreating innovations. This paper start with Levin and Reisiss demandcreating model considering spillovers. After some transformation, we get a model of cost reducing innovation.Therefore, we conclude that these two groups of innovations are the same in their essence.
