摘要
采用2003—2014年中国31个省(市)海外投资和国内并购的面板数据,利用贝叶斯随机前沿方法,分析了两种投资方式对地区创新效率的差异性影响。研究发现,海外投资和国内并购均对创新效率有正向影响,海外投资的作用更大;海外投资和国内并购都存在非线性的门槛效应,两者对数门槛值分别在7.61和5.76附近;OFDI和国内并购在促进创新效率方面不存在明显的替代或互补关系。
Using the panel data of 31 provinces (municipalities) during the period from 2003 to 2014, this paper investigates the variant effects of outward foreign direct investment (OFDI) and domestic M&A on regional innovation efficiency by utilizing Bayesian stochastic frontier function. The results show that : ( 1 ) Both the OFDI and domestic M&A have posi- tive effect on regional innovation efficiency, while the effect of OFDI is larger; (2) There are threshold effects for both OFDI and domestic M&A, and the logarithm threshold value for them is about 7. 61 and 5. 76 individually; (3) There is no substitutional or complementary relationship between OFDI and domestic M&A in promoting innovation efficiency.
