ABSTRACT

Technology-based firms use intellectual property protection mechanisms (IPPMs) to appropriate the returns to their research investments. The empirical literature has generally focused on the use of IPPMs by private sector firms to appropriate the returns to their privately financed R&D-based technologies. To date, studies have not considered the use of IPPMs by private sector firms whose research is publicly financed. We identify empirically a number of significant covariates with the use of a portfolio of formal IPPMs consisting of patents, copyrights, and trademarks. However, our multivariate empirical analyses show that caution is needed in generalizing about such covariates when discussing any one particular formal IPPM.

摘要

以技术为基础的公司使用知识产权保护机制 (IPPM) 将回报用于他们的研究投资。实证文献通常集中在私营部门公司使用 IPPM 以将回报分配给他们私人资助的基于研发的技术。迄今为止，研究尚未考虑公共资助的私营部门公司对 IPPM 的使用。我们通过使用由专利、版权和商标组成的正式 IPPM 组合，凭经验确定了许多重要的协变量。然而，我们的多元实证分析表明，在讨论任何一种特定的正式 IPPM 时，在概括此类协变量时需要谨慎。
