Abstract:

With the rapid increase of application for authorization of new plant variety right, the problem of "rich quantity and poor quality" has attracted wide attention. How to evaluate the quality of variety right has become an important theoretical and practical issue. In order to get scientific and rational judgment on the comprehensive quality level of plant new variety right in China, this paper firstly defined the definition of the quality of plant new variety right from the competitiveness angle; then set up the quality evaluation index system of new plant variety right from 3 attributes-legality, technicality and economy; and used the mean difference method to verify the effectiveness  of variety right quality index; finally constructed a comprehensive quality index of the plant new variety right to evaluation variety right quality by logic regression model so as to evaluate the quality of plant new variety right comprehensively and rapidly. Studies on quality evaluation of plant new variety right was not only beneficial for solving the problem in quality judgment standards for plant new variety right, providing a theoretical basis to improve the quality of plant new variety right, but also provided important references for value evaluation, transfer permission, financing, mortgage, and so on in China.

摘要：

随着植物新品种权的申请授权量急剧增长，品种权的“数量多、质量差”的问题引起了全社会的普遍关注。如何评价品种权质量成为重要的理论和现实问题。为了科学合理地判断我国品种权的综合质量水平，首先从竞争力的角度界定植物新品种权质量的定义，然后从品种权的法律、技术和经济三大属性建立品种权质量评价指标体系，并利用均值差异法验证品种权质量指标的有效性，最后采用逻辑回归模型构建品种权质量综合指数，以便全面、快捷地综合评价品种权质量。植物新品种权质量评估研究不仅有利于解决品种权质量判断标准问题，对提高品种权质量水平提供了理论依据，而且为我国品种权的价值评估、许可转让、融资、抵押等交易活动提供重要参考。
