中文摘要
本文测算企业内嵌生产率对跨国收入差异的贡献。所谓企业内嵌生产率,是指生产率中企业特有的组成部分,如技术蓝图、管理实践以及其他无形资本。利用跨国企业(MNE)的微观数据,我们比较同一跨国企业在不同国家的市场份额,并记录到其在欠发达国家的市场份额系统性地更大。这表明跨国企业在这些国家面临的竞争较少,且企业内嵌生产率在这些国家较为稀缺。基于这一观察,我们构建了企业内嵌生产率的度量指标。在我们的样本中,企业内嵌生产率的差异解释了劳均产出跨国方差的三分之一。
Abstract
We measure the contribution of firm-embedded productivity to cross-country income differences. By firm-embedded productivity we refer to firm-specific components of productivity, such as blueprints, management practices, and other intangible capital. Using micro-level data for multinational enterprises (MNEs), we compare market shares of the same MNE in different countries and document that they are systematically larger in less developed countries. This indicates that MNEs face less competition and that firm-embedded productivity is scarce in these countries. We implement a measure of firm-embedded productivity based on this observation. Differences in firm-embedded productivity account for one-third of the cross-country variance in output per worker in our sample.
