对外商直接投资是否以及如何影响了内资企业的生产率,现有的研究尚无统一定论。本文运用中国高技术产业行业层面数据检验了外商直接投资对内资企业生产率的影响,结果显示:外资促进了内资企业的生产率增长。进一步研究发现,外商直接投资较少的行业,内资企业研发资本投入的增加导致生产率的增长越快;外商直接投资较多的行业,内资企业增加研发人力投入会加快生产率的增长越快。
However, there is no unanimous conclusion about whether and how FDI affects the productivity of domestic-funded enterprises. This paper uses the data of China’s high-tech industry to test the impact of FDI on the productivity of domestic-funded enterprises. The results show that foreign capital promotes the growth of domestic-funded enterprises’ productivity. Further research shows that in industries with less direct foreign investment, the increase of R & D capital investment by domestic-funded enterprises leads to the faster growth of productivity; the industries with more foreign direct investment and the increased investment in R & D by domestic-funded enterprises will speed up the growth of productivity.
