中文摘要：

利用2006—2012年中国省际面板数据,采用面板回归和分位数回归模型研究研发投入强度对出口影响特征。实证结果表明研发投入强度对我国出口有明显促进作用,且与出口贸易之间存在倒“U”型特征。分位数回归进一步验证研发投入强度对出口的促进作用,同时实证因地区处于不同出口水平,研发投入强度对其出口影响存在差异性,即出口水平低的地区促进作用大,出口水平高的地区促进作用小。

英文摘要：

The paper adopts panel regression and quantile regression model to research the impact of R＆D intensity on China,s ex-port by using the panel data from China,s provinces during 2006-2012. The empirical results show that R＆D intensity has an obvious role in promoting export trade, there is an inverted U-shaped relationship between R＆D intensity and exportation. The quantile regres-sion further confirms the contribution of R＆D intensity to the exportation; it also proves that the influence of R＆D intensity is different due to the region’s different export levels; namely at the low level of export area,the effort of promotion is large; and at the high level of export area, the effort is small.
