| 摘 要： | 由于IT技术的易扩散性和强渗透性,IT产业的技术创新不仅会扩散到同类企业形成模仿,还会扩散到相关联的下游企业形成技术融合。鉴于此,本文从社会福利最大化角度出发,通过建立上、下游企业的环形城市模型,研究技术融合下IT产业的专利保护宽度的决定机制。本文认为技术创新产生的社会福利不仅包括上游企业创新和模仿产生的社会福利,还包括下游企业技术融合创造的社会福利。模型结果表明,技术融合下IT产业的最优宽度是创新程度、企业的吸收能力、消费者多样性偏好、环形城市总长度的减函数,是下游企业数、融合产品需求曲线斜率的增函数。

| Abstract: | Abstract In the IT industry, due to the easy proliferation and strong penetrability of IT technology, the innovation will not only spread to other upstream firms which produce imitation products, but also spread to the downstream firms. It results in the technological convergence. Therefore, from the point view of maximizing the net revenue of the whole society, the optimal patent breadth in a two ring city model consisting of upstream innovation firms and downstream convergence firms is discussed. The fact that the social welfare of technical innovation not only contains the revenue brought by upstream firms’ innovative and imitation products, but also contains the welfare brought by technological convergence of downstream firms is considered. It is shows that optimal patent breadth decreases with innovation degree, technique absorptive capacity of firms , the diversity of consumers’ preferences, and the total length of the circular city raising, but increases with the number of downstream firms and the slope of demand curve raising. |
