| 摘 要： | 创新产品的供求具有明显的时效性，着眼于某一时点上的价格均衡是没有意义的；同样，创新产品的市场结构在垄断和竞争中相交替，在既定市场结构前提条件下分析价格问题也是不科学的．通过分析技术进步引起的创新产品需求变化，以及技术扩散中大小企业创新产品的市场供给特点，把时间变量引入均衡价格模型，可从时序上考察创新产品价格的演变规律，并据此可对创新产品的产品生命周期等问题加以探讨。

| Abstract: | The supply and demand period of time, and thus studying of the innovated products has the noticeable feature of effectiveness for a given equilibrium price at a certain time is meaningless. Besides, the market structure of innovated products changes from monopoly to competition, and analyzing the price problem on the given premise of market structure is not scientific The article studies the change of the demand of the innovated products caused by the technology advances and the features of market supply of innovated products of small and big enterprises in technology diffusion. By introducing time variable into the equilibrium price model, it studies the evolution law of innovated product price from the time order. The article, based on these, probes further into the life cycle of innovated products. |
