国内外技术获取与高技术产业创新绩效差异——基于时滞视角的比较分析

开放式创新背景下，外部技术获取方式中的国内技术购买和国外技术引进对创新绩效的影响并不相同。运用2012-2018年高技术产业省际面板数据进行实证分析，检验在不同滞后期，技术购买、技术引进对新产品销售收入和专利的差异化影响。实证结果表明：技术购买、技术引进对高技术产业创新绩效影响的显著差异在于影响时滞不同；技术购买能在短期提升新产品销售收入和发明专利申请量；技术引进在短期只能提升新产品销售收入，对发明专利申请量的提升及对新产品销售收入的增加需要更长的时滞。内部研发支出在技术购买、技术引进与高技术产业创新绩效间发挥的调节作用不尽相同。因此，高技术产业企业应充分考虑技术购买、技术引进对创新绩效影响的时滞差异，根据不同的创新发展目标选择不同来源的外部技术，保证必要的内部研发支出并提高国外技术吸收能力。

Different Effects of Acquisition of Foreign or Domestic Technology on Innovation Performance of High-Tech Industry —— A Comparative Analysis from the Perspective of Time Lag

In the context of open innovation, the two approaches of external technology acquisition, domestic technology purchase and technology import, have different effects on innovation performance. Based on China high-tech industry provincial panel data during 2012-2018, this paper investigates the difference in the effects of domestic technology purchase and technology import on innovation performance in different lag phases. It is found that the significant difference between domestic technology purchase and technology import on innovation performance of high-tech industry is shown as effects of different time lags. Domestic technology purchase can promote the new products sales and applications of invention patents in a relatively shorter time. Technology import can only promote new products sales in the short term, but it can further promote new products sales simultaneously promote applications of invention patents in a later lag. Internal R&D investment moderates the relationship of the two different sources of external technology and innovation performance in high-tech industry differently. Therefore, high-tech industrial enterprises should take time-lag into account and purchase external technology from different sources according to different innovation development goals. Necessary internal R&D investment in high-tech industry should also be maintained to improve the ability to absorb foreign technology.
