尽管研发支出被认为是生产力增长和发展的关键，但问题仍然在于其贡献是否取决于特定国家和行业的实际发展水平以及在全球价值链中的地位。在本文中，我们使用行业层面面板数据和随机前沿生产函数方法分析了 OECD 国家研发对行业和部门层面效率（生产率）的相对贡献。研究结果表明，R&D资本生产率提升效应随着技术水平的提高而增大；实物资本则表现出相反的效果。不同行业的效率分布呈现出明显不同的差异，反映出不同的竞争程度和价值链结构。在不同的外部因素中，全国范围内受过高等教育的劳动力比例与效率呈现很强的正相关性，而对于其他外部因素，不同行业的影响存在差异。研究结果表明，在设计研发政策措施时需要考虑产业结构。
While research and development expenditures are considered a key to productivity growth and development, the question remains whether their contribution could depend on the particular countries’ and industries’ actual development levels and positions in global value chains. In this paper we analyse the relative contribution of R&D to the efficiency (productivity) on the industry and sector level in OECD countries using industry-level panel data and the stochastic frontier production function approach. The results indicate that R&D capital productivity enhancing effect increases with the level of technology; physical capital shows the opposite effect. The distribution of efficiency across industries shows remarkably different variances, reflecting different degrees of competition and the structure of value chains. Among different external factors, the share of labour with tertiary education at the national level showed a strong positive correlation with efficiency, while for other external factors the effect varied across the industries. The findings imply that in the design of R&D policy measures the structure of the industries needs to be considered.
