This article uses firm-level data for the Czech Republic to show that during 1992–96 foreign investment had the predicted positive impact on total factor productivity growth of recipient firms. This result is robust to corrections for the sample bias that arises because foreign companies tend to invest in firms whose initial productivity is above average. Together, joint ventures and foreign direct investment appear to have a negative spillover effect on firms that do not have foreign partnerships. However, with foreign direct investment alone, the magnitude of the spillover becomes much smaller and loses significance. This result, in conjunction with the fact that joint ventures and foreign direct investment account for a significant share of total output in many industries, suggests that further research is required to determine the extent of knowledge diffusion from firms that have foreign links to those that do not.
这篇文章使用捷克共和国的公司层级数据表明,在1992年至1996年期间,外国投资对接受企业的全要素生产率增长产生了预期的正面影响。这个结果在修正因外国公司倾向于投资于初始生产率高于平均
水平的企业所造成的样本偏差后仍然具有稳健性。总体来看,合资企业和外商直接投资对没有外国合作伙伴的企业似乎有负溢出效应。然而,仅考虑外商直接投资时,溢出的幅度变得很小并失去了显著性。这个结果,加上合资企业和外商直接投资在许多行业占据了总产出的相当大份额,表明需要进一步的研究来确定拥有外国联系的企业与没有外国联系的企业之间的知识扩散程度。
