采用基于松弛测度的数据包络分析方法测度中国高技术行业的技术效率,并运用系统广义矩估计考察本土技术转移、国外技术引进和FDI三种技术转移方式溢出效应的行业异质性。结果表明,本土技术转移显著促进了高技术行业效率提升,且对高效率行业的溢出效应远高于低效率行业;国外技术引进对高效率行业的溢出效应不显著,对低效率行业有显著负向溢出效应;而FDI对高效率行业有显著的正向溢出效应,对低效率行业的溢出效应不显著。
The technique of data envelope analysis based on relaxation measure was used to measure the technical efficiency of China’s high-tech industries. The system heterogeneity of spillover effect of the three technology transfer modes of domestic technology transfer, foreign technology introduction and FDI was investigated using the system GMM. The results show that the local technology transfer has significantly promoted the efficiency of high-tech industries, and the spillover effect on high-efficiency industries is much higher than that of low-efficiency industries. The spillover effect of foreign technology introduction on high-efficiency industries is not significant, To the spillover effect; while FDI has a significant positive spillover effect on the high-efficiency industry and no significant spillover effect on the low-efficiency industry.
