企业研发活动投入资源多、面临风险大,研发的成果又有公共品属性。这些都阻碍了企业进行大规模的研发活动。专利制度在保护知识产权的同时,也影响了技术溢出及知识扩展。如何解决专利悖论带来的困惑,尽可能地提高研发收益,降低研发成本,是促进企业研发活动深入的关键。本文从企业合作研发可以缩短研发时间、可以提高企业利润以及合理地划分企业研发竞争与合作的边界这三个角度对这一问题进行了研究,分析了企业研发合作的效率贡献,并根据竞争与合作的数理模型,从四个区域探讨了企业合作研发的福利边界。
R & D activities invested more resources, facing the risk of R & D results have public goods attributes. These are hindering enterprises from carrying out large-scale R & D activities. The patent system, while protecting intellectual property rights, has also affected technology spillovers and knowledge expansion. How to solve the puzzles brought about by the patent paradox and how to raise the R & D income and reduce the R & D cost as much as possible is the key to promote the R & D activities of enterprises. This paper studies the issue from the perspectives of enterprise R & D cooperation, which can shorten the R & D time, improve corporate profits and divide the R & D competition and cooperation rationally, and analyze the efficiency contribution of R & D cooperation. According to the competition and Cooperation mathematical model, from four regions to explore the business cooperation in research and development of welfare boundaries.
