基于专利文献信息的农业专利质量影响因素分析——以新疆生产建设兵团为例

Research on Influencing Factors of Agricultural Patent Quality Based on Patent Document Information——Taking Xinjiang Production and Construction Corps as an Example

专利质量是衡量一个国家或地区科技创新水平的重要标尺。本文以中国专利局1985~2016年间授权的新疆兵团农业专利为样本,基于专利文献信息的角度,构建COX比例风险(CPH)模型,从引证类指标、技术类指标、经济类指标等维度,对农业专利质量影响因素进行实证分析。研究表明:兵团农业专利数量逐年增加,但专利质量处于不稳定波动状态;权利要求数、发明人数量和说明书及附图页数能够不同程度地表征农业专利质量,且对专利维持时间都有正向的影响;专利申请人类型对专利生存风险率有显著的影响,企业的专利生存风险率明显低于大学,通过鼓励原创、完善专利管理办法、加强专利成果转化平台建设、加大企业科技创新优惠政策支持力度等措施,有助于提升兵团农业专利质量。

Patent quality is an important yardstick for measuring the level of scientific and technological innovation in a country or region.Taking the agricultural patent of Xinjiang Corps issued by State Intellectual Property Office (SIPO) during the period of 1985-2016 as a sample, the Cox Proportional Hazards Model was constructed based on the perspective of patent document information.From the four dimensions of citation category, technical index, economic index and other indicators, the empirical analysis was conducted to analysis the factors affecting the quality of agricultural patent.The research showed that the number of agricultural patents in corps increases year by year, but the quality of patent was in an unstable state.The number of claims, the number of inventors and the number of drawings and pages could represent the quality of agricultural patents to varying degrees, and had a positive impact on the duration of patent maintenance.The human type of patent application had a significant impact on the survival risk of patents, and the patent survival risk rate of enterprises was significantly lower than that of universities.By encouraging the original, improving the patent management measures, strengthening the original, improving the patent management measures, strengthening the platform for the transformation of patent achievements, and increasing the support of enterprises'preferential policies for scientific and technological innovation, the quality of agricultural patents of the Corps will be improved.
