研发外包是否会抑制我国制造业自主创新能力?

Does R&D Outsourcing Inhibit Innovation Performance in Chinese Manufacturing?

本文利用2002年、2007年中国投入产出表和联合国贸发数据库中数据，测算历年我国制造业的研发外包率，随后利用2003~2011年制造业细分行业的面板数据，从创新能力和创新效率两个维度，考察了研发外包对我国自主创新能力的影响。实证结果显示：研发外包可以显著地促进我国制造业的创新能力和创新效率。研发外包每增加1％，将会促进制造业创新能力提高0．322％，创新效率改善0．0884％。从作用机制来看，研发外包对创新效率的正向作用主要体现在对纯技术进步率的提高上。本文进一步运用Hansen（1999）提出的门槛检验方法对研发外包创新提升效应的若干因素及其门槛特征进行检验，并从吸收能力和议价能力两个方面分析和筛选出适合开展研发外包的行业。本文的研究结论表明在后危机时代，研发外包是我国制造业提高创新能力，进而顺利完成转型升级任务的最佳选择。

In this paper, we not only utilize two input-output tables of 2002 and 2007, but also approach the data from UNCTAD database, then estimate the R＆D outsourcing rate of China＇s manufacturing industry. In addition, we analyze the effect of R＆D outsourcing on innovation capacity and innovation efficiency by manufacturing industry segments panel data from 2003 to 2011. The empirical results indicate that R＆D outsourcing can significantly promote innovation capacity and innovation effi- ciency in manufacturing industry. When R＆D outsourcing increase 1%, it will increase manufacturing innovation capacity by 0. 322% and improve innovation efficiency up enhance by 0. 0884%. From the mechanism of action, the positive effect of R＆D outsourcing on innovation efficiency is mainly reflected in the improving rate of pure technological progress This suggests that R＆D outsourcing is the best strategies for China＇s manufacturing industry in order to improve the innovation ability and successfully complete the transformation and upgrading in the post-crisis era.
