服务贸易结构对我国专利数量的影响研究——基于技术溢出效应的角度

The Influence Analysis of Service Trade Structure on Patent Quantity Based on Technological Spillover Effect

实证分析了服务贸易结构对我国专利数量的影响。研究表明,劳动密集型服务贸易对专利数量有负面影响,其弹性系数为-0.026;资本密集型服务贸易和技术知识密集型服务贸易对专利数量有正面影响,其弹性系数分别为0.029和0.058。将专利细分为发明专利、实用新型和外观设计后,从横向上比较,我们发现在对技术含量最高的发明专利的溢出效应中,技术知识密集型服务贸易所占的比重最大;而从纵向上看,在对技术含量最低的外观设计的溢出效应中,这3种服务贸易的溢出效应都要显著大于其对于其它两种专利的溢出效应。

This paper empirically analyzes the influence of service trade on the patent quantity in our country. Our analysis shows that labor intensive service trade has negative influence on patent quantity, the elastic efficient is -0.026.While the capital intensive service trade and technology and knowledge intensive service trade have positive influence on the patent quantity, with elastic efficient as 0.029-0.058 respectively. The patents are further specified into inventions, utility and design patent, we find seen from the horizontal level, technology and knowledge service trade has the biggest influence on the invention; and seen from the vertical level, the three kinds of service trade has bigger technological effect on the design patents than on the other patens.
