随着科技的发展和国际间贸易的增加,知识产权资产交易日益频繁,技术许可贸易也愈加广泛。在技术许可贸易中,最重要的是确定许可费的支付方式和金额,尤其以提成式支付许可费方式,许可费率的计算就显得更加重要。本文运用统计学中的综合评价法,分析影响许可费率的主要因素,构造综合评价体系,并与传统许可费率确定方法相结合,最终合理确定许可费率。 With the development of science and technology and the increase of international trade, the trade of intellectual property assets has become increasingly frequent, and the trade in technology licensing has become more and more widespread. In the technology licensing trade, the most important thing is to determine the payment method and amount of license fee, especially the royalties payment method, the calculation of the license fee becomes even more important. In this paper, we use the comprehensive evaluation method in statistics to analyze the main factors affecting the royalty rate, construct the comprehensive evaluation system, combine it with the traditional method to determine the royalty rate, and finally determine the license rate reasonably.
