贸易自由化、中间品进口与中国技术创新——1998-2012年省级面板数据的实证研究

Trade Liberalization, Intermediate Product Imports and Technical Innovation in China: An Empirical Study Based on Provincial Panel Data from 1998-2012

进口中间品的贸易自由化对中国技术创新产生什么影响?本文将中间品进口对我国技术创新的影响归结为贸易自由化激励效应、研发资本效应和人力资本激励效应,并借助国际R&D溢出模型,将贸易自由化纳入模型中,运用我国1998-2012年的省际面板数据进行相关实证检验。结果显示:进口中间投入品对我国技术创新有明显的促进作用,中间品进口每增加10%,中国技术创新提高1.6%;进口中间品的贸易自由化每增加10%,中国技术创新将提高0.3%等。

From the perspective of trade liberalization, this paper ascribes the impact of intermediate product imports on China＇s technical innovation to the in- centive effects of trade liberalization, R＆D capital effects and human capital in- centive effects. Drawing on the Model of international R＆D spillovers which in- corporates trade liberalization, this paper conducts an empirical test by using Chi- na＇ s provincial panel data during 1998- 2012. The results show that the import of intermediate products has a promoting effect on technology innovation in Chi- na, with every 10 percent increase in the import of intermediate products corre- sponded to a 1.6 percent rise in China＇ s technical innovation, and every 10 per- cent increase in the trade liberalization of intermediate products import corresponded to a 0.3 percent rise in China＇ s technical innovation.
