R&D, Human Capital and International Technology Spillovers: A Cross‐country Analysis
基于创新驱动增长理论，利用1960年代初至1990年代初OECD国家数据，发现国内外研发和人力资本均显著影响生产率增长，且人力资本与追赶过程存在交互作用。
This paper is based on recent developments in the theory of innovation‐driven growth that emphasize both the importance of R&D efforts — domestic as well as foreign — for explaining national productivity, and the complementarity between R&D and human capital investments. Estimates of specifications, in growth terms and in level terms, on a cross‐section of OECD countries from the early 1960s to the early 1990s lend strong support to this thesis. The data show a significant influence of both domestic and foreign R&D. Moreover, there is clearly a net positive impact of human capital. The level and growth rate of human capital are shown to affect productivity growth and there is evidence of interaction with the catch‐up process.
