以三种专利授权量代理不同层次的技术创新能力,以进出口贸易中资本品或高技术品所占的比例衡量贸易结构。研究发现:贸易结构的变化显著影响我国的技术创新能力,但主要体现为实用新型和外观设计专利的增加,对发明专利的影响则不显著,并且这种贸易溢出的技术创新效应必须以国内技术吸收能力的同步提升为条件。因此,贸易溢出可以促进技术创新,但最根本的技术创新——技术发明还必须依靠自主研发。
Acting at three levels of patent authorization amount of different levels of technological innovation, import and export trade in the proportion of capital goods or high-tech products to measure the proportion of trade. The findings are as follows: The change of trade structure significantly affects our country’s technological innovation capability, but mainly reflects the increase of utility model and design patent, but has no significant effect on the invention patent. And the technological innovation effect of this trade spill must be based on domestic technology Absorption ability to enhance the synchronization of conditions. Therefore, trade spillover can promote technological innovation, but the most fundamental technological innovation - technological invention must also rely on independent research and development.
