政府研发资助是否促进了技术进步——来自66个国家和地区的证据

Whether the government R&D fundings promote technological progress: Evidence from 66 countries and regions

本文利用66个代表性国家1996-2013年的跨国面板数据考察政府研发资助对技术进步的影响,研究结果表明,政府研发资助的技术进步效应具有国别差异。分区域的估计结果表明,政府研发资助的技术进步效应受到多种因素的影响。其中,高收入水平国家政府研发资助的技术进步效应显著为正,中低收入水平国家政府研发资助的技术进步效应显著为负;高城市化水平国家政府研发资助显著促进技术进步,但低城市化水平国家政府研发资助没有对技术进步起到促进作用;人口密集区政府研发资助的系数显著为正,而人口中等区和人口稀少区政府研发资助的系数均显著为负,且人口稀少区的系数高于人口中等区。

Using panel data of 66 typical countries in 1996 -2013, this paper empirically studies the effect of government R＆D fund- ings to technological progress. The results show that the effect of government R＆D fundings to technology progress is different among countries. The regional estimation results show that the technology progress effect of government R＆D fundings is affected by many fac- tors. Among them, The effect is significantly positive in high income countries, significantly negative in nations of low income; Same- ly, The effect is positive in nations of high urbanization level, but government R＆D fundings can not promote technological progress in the low level of urbanization countries; the coefficient of government R＆D fundings in densely populated areas is significantly positive, while the coefficients are all significantly negative in the middle population area and sparsely populated district , and the coefficient of sparsely populated areas is higher than middle population area.
