The Effects of Investment in Education and Training on Productivity Growth in the European Union
利用2010-2021年28国17行业数据，研究在职培训如何直接及通过与其他无形资产（如研发、组织资本）的互补效应促进劳动生产率增长，发现培训投资显著提升生产率，尤其在商业服务业中与组织资本的互补性最强。
ABSTRACT This paper examines how on‐the‐job training affects labor productivity growth, both directly and through its interaction with other intangible assets such as knowledge codified in software and databases, research and development (R&D) and intellectual property assets, organizational know‐how and branding. Using EUKLEMS & INTANProd data over 2010–2021 for 17 industries in 28 countries, we apply a difference‐in‐differences approach within an augmented production function. Results show that business investment in training significantly enhances labor productivity growth, especially in industries with higher training investment intensity, with the strongest complementarities—particularly with organizational capital—observed in business services.
