标准导向型技术的合作与独立研发

Cooperative R&D or non-cooperative R&D on standard-oriented technology

围绕信息技术产业中的标准导向型技术,分析和比较了合作研发与独立研发的绩效.依据企业是否协调信息分享和研发投资两个纬度,将标准导向型技术的创新模式细分为完全的研发竞争、专利联盟、纯粹的合作研发和带专利池的合作研发,在AJ和KMZ两个经典模型的基础上发展了双寡头模型来研究4种创新模式的绩效.博弈模型得出了一些新结论:第1,克服信息分享的外部性带来研发投资的增长,与克服研发投资外部性带来的投资增长,他们的作用机制不完全相同.第2,标准导向型技术的4种创新模式,没有哪一种模式绝对优于另3种模式.技术溢出水平是决定最优研发模式的中间变量,而它又取决于行业的其他特征.

Our paper has analyzed and compared cooperative R＆D and non-cooperative R＆D on standard-oriented technology. According to whether a firm coordinates R＆D investment and information sharing, we have classified modes of innovation on standard-oriented technology into four types, which are complete R＆D competition, patent pool, pure R＆D cooperation and R＆D cooperation with patent pool. Based on the two classical models, we have developed a new model to discuss the performace of the above four modes. Some new findings are： On the one hand, the mechanism of overcoming the externality of information sharing on the R＆D investment is partly different from that of the externality of R＆D investment;On the other hand, none of the four modes is superior to the other three, echnology spillover is only one of the key middle factors that determinate which mode is the best and it is dependent on the character of the industry .
