Abstract: In the background of accelerating the construction of the New Development Pattern, the import of high-quality products is of great significance to promoting the smooth domestic and international circulation. In addition to affecting the productivity of importers, the technical attributes of suppliers contained in imports can also produce secondary spillovers to relevant departments through innovation incentives and transversal technology inspiration effect. This paper matches China?s industrial industry data with the country-specific import data under the three-digit code of the Standard International Trade Classification (SITC), and empirically tests the secondary spillover of the technical attributes of imports to the horizontal and technology-adjacent industries. The results show that, Firstly, the technical attributes of imports have a significant innovation incentive effect on horizontal industries, but no transversal technology inspiration effect. Secondly, Technology-adjacent industries can obtain innovation incentive and transversal technology inspiration effect at the same time, but the latter is the main aspect, that is, inspiration trigger or knowledge transfer with the help of imports with similar technical principles. Thirdly, The innovation incentive of the technical attributes of imports to horizontal and technology-adjacent industries increases with the increase of the proportion of national capital, while the transversal technology inspiration effect of technology-adjacent industries is not regulated by the proportion of national capital. Facing the realistic pressure of increasing uncertainty in the external environment, China should pay more attention to using the competitive pressure, innovation incentive and learning window provided by high-quality imports, promote sufficient spillover of high-quality innovation factors contained in imports through the domestic circulation, advance the docking of standards, personnel flow, supervision and certification in a wider range, deeper level and internal-external integration, and give full play to the leading role of state-owned capital in open innovation.
