Abstract: By employing survival analysis method on a large sample of invention patents from 211 project universities, this study constructs likelihood curve of patent assignment based on patent life cycle. The result shows that assignment likelihood of university patents first increases and reaches the peak five years after the patent application date, then decreasing over time. The study delves into the role of the university technology transfer office in university patent assignment process and the differential effects it might exert. Results of accelerated time models suggest that in general, the establishment of university technology transfer office does not have a significant effect on patent assignment speed. However, the existence of technology transfer office amplifies the negative relationship between the patent geographic protection scope, the number of inventors and the time needed for patent assignment, while it weakens the negative effect of inventors’ prior experience on assignment time. The study extends the understanding of university patent assignment process from a micro perspective and provides theoretical implications for improving the efficiency of university technology transfer offices.

摘要： 该研究构建了基于专利生命周期的技术转让生存分析模型，利用116所211高校的专利转让微观数据拟合了技术转让可能性曲线。专利转让的可能性呈先增后减的趋势，在申请后第五年左右达到峰值。文章进一步探究了技术转移办公室在高校技术转让过程中的微观作用机制及其在不同情境中的异质作用效果。研究结果表明，技术转移办公室对高校的专利转让速度没有直接的促进作用，但技术转移办公室的存在强化了专利地域保护范围、发明人数量对于专利转让时间的负向影响，同时削弱了发明人团队以往专利转让经验对后续专利转让时间的影响。文章在微观层面上对高校技术转让行为模式研究进行了拓展，对进一步提升技术转移办公室的作用效果具有重要的理论参考价值。
