本文根据日本企业的数据，在将企业异质性模型扩展为同时考虑内部和外部（外包或技术购买）R & D战略的简单理论框架的基础上，对企业的生产率与R& D战略和出口的联合决策之间的关系进行了实证分析。非参数和半参数方法的实证结果表明，无论采用内部R&D策略还是外部R&D策略，从事R&D活动的出口企业的生产率均高于非出口企业和不从事R&D活动的出口企业，并且采用两种R&D策略的出口企业的生产率最高。结果表明，开放式创新战略是对内部研发战略的补充，对于进一步促进国际化企业的创新至关重要。
This paper empirically examines the relation between a firm's productivity and its joint decision of research and development (R&D) strategy and exporting, based on Japanese firm-level data and the simple theoretical framework that extends the firm heterogeneity model so that both internal and external (outsourcing or technology purchase) R&D strategies are taken into account. The empirical results from nonparametric and semiparametric methods show that exporting firms engaged in R&D activities are more productive than non-exporters and exporters with no R&D, regardless of whether internal or external R&D strategy is adopted, and that exporters which employ both R&D strategies are the most productive. The results suggest that an open innovation strategy is complementary to an in-house R&D strategy and is crucial for further promoting innovation for internationalized firms.
