专利价值分析可以更好地测度创新活动产出和认识创新活动规律。该文构建包含USPTO授权基因工程发明专利特征和专利维持状况的专门数据库，经SAS9．1．3软件运行logistic回归模型，考察基因工程专利维持的影响因素，揭示生物技术创新活动特点。对1991—1996年间授权的1063项基因工程发明专利的实证研究发现：基因工程专利呈现高维持率特征，61％的专利维持到法定年限，平均维持时间长度为13．65年；logistic模型分析结果表明，基因工程专利维持受到专利所有权人数量（组织间合作）、所有权人规模、被引用情况和内部连续创新活动的显著影响。这些研究认识对技术政策制定和创新战略管理有丰富的借鉴意义。
專利價值分析可以更好地測度創新活動產齣和認識創新活動規律。該文構建包含USPTO授權基因工程髮明專利特徵和專利維持狀況的專門數據庫，經SAS9．1．3軟件運行logistic迴歸模型，攷察基因工程專利維持的影響因素，揭示生物技術創新活動特點。對1991—1996年間授權的1063項基因工程髮明專利的實證研究髮現：基因工程專利呈現高維持率特徵，61％的專利維持到法定年限，平均維持時間長度為13．65年；logistic模型分析結果錶明，基因工程專利維持受到專利所有權人數量（組織間閤作）、所有權人規模、被引用情況和內部連續創新活動的顯著影響。這些研究認識對技術政策製定和創新戰略管理有豐富的藉鑒意義。

The assessment of patent value plays an important role in measuring innovation outputs and understanding innovative activities. With an aim of the relationship exploration among bio - tech patent renewal, patent value, and influencing factors, a database of genetic engineering patents, which includes characteristics of patent and the owner（s） , and the patent renewal data collected from USPTO are retrieved. Based on a logistic regression model and SAS 9.1.3 calculation, the factors which affect the renewal of genetic engineering patent are found and then used to discuss the specific phenomena of bio - teeh innovative activi- ties. Through analyzing 1,063 US genetic engineering patents granted during the period of 1991 - 1996, it is found that genetic engineering patents have high renewal rate, and 61% patents which are mosdy owned by large entities are renewed to full time and the average age is 13.65 years. The result of logistic regression shows that the renewal of genetic engineering patents is effectively influenced by the assignee number, the scale of entity, forward citation, and internal sequential innovation. This fact has insightful implication for technology policy - making and innovation strategy management.
