本文以西德制造业为样本，探讨了外部（合同）与内部（内部）研发投资的生产率效应。研究结果有力地证明了生产率与外部研发在总研发中所占份额之间存在正相关关系。这一结果是稳健的替代计量经济学规范。因此，研究结果表明，内部和外部R&D之间的决定并不重要。此外，结果表明，生产率和外部R&D的份额之间的非线性关系，为高技术产业，暗示在生产率的影响，外部R&D的份额增加总R&D。
The paper explores the productivity effects of investment in external (contract) vs. internal (in-house) R&D in a sample of West-German Manufacturing Industries. The results provide strong evidence of a positive relationship between productivity and the share of external R&D in total R&D. This result is robust to alternative econometric specifications. Thus, findings suggest that the decision between internal and external R&D does matter. Moreover, results imply a nonlinear relationship between productivity and the share of external R&D for higher-technology industries, hinting at decreasing productivity effects of an increasing share of external in total R&D.
