高技术产业创新活动驱动区域经济发展的作用机制

The Mechanism of High-Tech Industry Innovative Activities Driving Regional Economic Development

摘要:

基于中国2011-2021年的省级面板数据，构建两种空间权重矩阵，运用动态空间杜宾模型，探讨了在高技术产业科技密集度及技术市场化水平的作用下自主研发创新及跨国创新引入对经济发展的不同影响，并进一步分地区对比分析了高技术产业技术市场化水平、不同创新活动与区域经济发展的内在关系。实证结果表明：（1）自主研发创新对经济发展的积极作用在长期内效果更明显，跨国创新引入对经济发展的积极作用在短期内效果更明显。（2）高技术产业科技密集度对当地的自主研发创新/跨国创新引入与经济发展之间的关系具有显著的正向调节作用，且具有持久性。（3）随着高技术产业中技术市场化水平的提升，自主研发创新、跨国创新引入对区域经济发展的积极关系存在先下降后上升、先上升后下降的非线性变化，但这种正向作用整体力度呈现减弱趋势。（4）在科技密集区/欠密集区，随着高技术产业技术市场化水平的变化，不同创新活动对区域经济发展非线性影响的变化趋势虽然相同，但总体作用力度有所差异。

Abstract:

Based on the provincial panel data of China from 2011 to 2021, this paper constructs two kinds of spatial weight matrices and uses the dynamic spatial econometric analysis model to empirically discuss the different impacts of two innovation activities on economic development under the influence of high-tech industry the science and technology intensity and technology marketization level, and further comparatively analyzes the internal relationship among high-tech industry technology marketization level, different innovation activities and regional economic development in different regions. The empirical results show that: (1) The positive effect of independent R&D innovation on economic development is stronger in the long run, and the positive effect of the introduction of transnational innovation on economic development is stronger in the short run. (2) The science and technology intensity of high-tech industries has a significant positive moderating effect on the relationship between independent R&D innovation/transnational innovation introduction and economic development in that region, and it has a lasting effect. (3) With the improvement of the level of technology marketization in high-tech industries, the positive relationship between independent R&D innovation/ the introduction of transnational innovation on regional economic development has a nonlinear change of first decreasing and then increasing /first increasing and then decreasing, but the overall strength of this positive effect shows a weakening trend. (4) In sci-tech intensive/ less-intensive areas, with the change of technological marketization level of high-tech industry, the nonlinear influence of different innovation activities on regional economic development is the same, but the overall strength of effect is different.
