【摘要】：采用1998-2013年中国30个地区的平衡面板数据,运用Cobb-Douglas形式的创新生产函数,将外商直接投资(FDI)规模及其进入速度和区域创新能力纳入到同一个研究框架中,分析了外商直接投资的规模及进入速度对区域创新能力的影响。研究结果显示,外商直接投资规模以及进入速度对区域创新能力产生了显著的促进作用,通过加入交互项,证实了外商直接投资存量负向调节外资进入速度对区域创新能力的影响。当地区的外商直接投资规模存量超过一定水平时,外资规模进入速度对区域创新能力的影响由正转负。为了检验回归结果的稳健性,对RD投入和FDI进行测算时选取了不同的折旧率,进而得到了不同的面板数据以进行回归估计,发现外商直接投资规模及进入速度变化对区域创新能力的影响是稳健的。
[Abstract]:Based on the balance panel data of 30 regions in China from 1998 to 2013 and the innovative production function in the form of Cobb-Douglas, the scale of foreign direct investment (FDI) and its entry speed and regional innovation ability are brought into the same research framework.The influence of FDI scale and entry speed on regional innovation ability is analyzed.The results show that the scale of foreign direct investment (FDI) and the speed of entry play a significant role in promoting regional innovation ability by adding interactive items.It is proved that the stock of FDI negatively regulates the influence of FDI entry speed on regional innovation ability.When the stock of foreign direct investment exceeds a certain level, the impact of the entry speed of foreign direct investment on the regional innovation ability changes from positive to negative.In order to test the robustness of regression results, different depreciation rates are selected when R D input and FDI are measured, and then different panel data are obtained for regression estimation.It is found that the impact of the change of FDI scale and entry speed on regional innovation ability is robust.
