| 摘要: |
| 在引入R＆D强度的扩展柯布道格拉斯函数的基础上,构建多元线性回归模型,研究中国东北、东部、中部和西部四区域31个省市自治区的R＆D强度对经济增长的动态影响及区域差异。研究表明,四区域R＆D强度与经济增长之间均呈正相关,但区域差异明显。东部地区R＆D对经济增长的影响最为显著;东北地区与中部地区各要素产出弹性相差不大,R＆D产出弹性均低于东部地区;西部地区R＆D产出弹性最低,但物质资本产出弹性相对较高。今后应继续贯彻实施国家区域发展战略,加大R＆D投入并配套相应的物质资本投入,完善区域发展带动机制,促进区域经济均衡发展。 |

| Abstract: |
| Based on the Cobb Douglas function introduced to the intensity of R&D, the multiple linear regression model is constructed to research the dynamic impact of R&D intensity on economic growth and regional differences of 31 provinces and areas in the northeast, eastern, central and western regions in China. The conclusions are: in the four regions, there is a positive correlation between R&D intensity and economic growth, but the regional differences are significant and R&D impact on economic growth in the eastern region is the most significant; the output elasticity of factors of the northeast region and the central region shows little difference, and is lower than that of the eastern region; the R&D output elasticity of the western region is the lowest, but material capital output elasticity is relatively high. Finally, we put forward the countermeasures to promote the regional economic equilibrium growth. |
