多渠道国际技术溢出效应的区域差异性研究

The research on the regional difference of multi-channel international technology spillover effects

文章采用2004年-2015年全国30个省市、自治区的数据,结合空间计量的方法研究了国际R&D溢出对中国经济增长及全要素生产率的影响。从全国整体看,自主创新、对外投资以及出口贸易均能显著促进地区经济增长,但仅有进口贸易能显著提高全要素生产率;东部地区自主创新、对外投资、进出口贸易均能显著促进地区经济增长,而进出口贸易则对东部地区全要素生产率具有积极影响;中部地区自主创新和对外投资会促进该地区经济增长,而外商投资、对外投资以及进口贸易则能提升中部地区全要素生产率;对于西部地区,自主创新和进口贸易能显著促进地区经济增长,同时进口贸易还能显著提高西部地区全要素生产率。基于上述研究结论,提出我国各区域应采取不同的对外经济策略。
