高技术渗透是推动产业高技术化的有效方式，是实现我国产业结构调整、经济成功转型的优化选择。本文运用随机分析中的生灭过程理论，细致地描述了高技术渗透的微观机理，探讨了高技术渗透的三种演进模式；并且结合数理方法，给出了报酬递增机制是主导技术选择的决定因素的论断的一个证明 High-tech infiltration is an effective way to promote high-tech industries and the optimal choice to realize the industrial restructuring in our country and the successful transformation of economy. In this paper, we use the theory of birth-death process in stochastic analysis to describe the micro-mechanism of high-tech infiltration in detail and discuss the three evolution modes of high-tech infiltration. Combining with the mathematical method, we also give the decision that reward increasing mechanism is the dominant technology choice A proof of the argument
