省域研发投入溢出效应的实证分析

An Empircial Analysis on Spillover Effects of Provicial R&D Input

基于我国2005—2014年的31个省际面板数据,将研发投入作为变量引入到区域经济增长的回归模型中,并结合空间计量的方法研究分析了本省的研发投入对经济的增长和邻近省份的研发投入的溢出效应。全样本和分区域结果都表明自主研发投入对经济的增长均有明显的促进作用;自主研发投入的经济增长效应存在差异,东部最强,中部次之,西部最弱,邻近省份的研发投入溢出效应显著,东中西部呈梯度下降趋势。

Based on. the 31 provincial panel data from 2005 to 2014, the R＆D input is introduced as a variable into the regression, model of regional economic growth. Combined with the spatial measurement method, this paper analyzes the relationship between. R＆D input and economic growth in. neighboring province. The results of the sample and the surb-region. show that the independent R＆-D input has obvious effect on. economic growth. The effect of the independent R＆D input on. economic growth exist difference which is strongest in. the east, the middle second and the weakest in. west. Moreover, the effect of R＆-D input is obvious in. neighboring province, which shows a gradient descent in. east, middle and west.
