在考虑存在竞争产品、周期广告投入、产品使用寿命及兼顾市场价格对创新产品市场最大潜力的影响基础上,建立了一类新的技术创新扩散微分动力学速度模型.根据微分动力学系统稳定理论,对该微分动力学模型进行了稳定性分析.发现在满足一定的条件下,该技术创新市场扩散量会存在至少一个周期解,并在一定条件下是全局稳定的.
With a brief review of the developing process of the research on new product diffusion, a dynamical model is formulated, in which the competitor, periodical advertisements and the product life-span are taken into consideration. And in this model the market price will affect the market potential. If given a restrict condition, the model has at least a positive periodic solution with a stability analysis on it. And the solution is global stable with another restrict condition.
