| 摘 要： | 本文基于1998-2012年全国省级面板数据，运用动态面板系统广义矩估计法，从数量和质量两个维度，实证分析了信贷扩张与研发投入对中国经济增长的作用。结果表明：从全国的总体来看，信贷扩张和研发投入对经济总量增长均起到了促进作用，但研发投入的作用强于信贷扩张；研发投入对经济质量提升同样具有正向促进作用，而信贷扩张则相反。此外，二者对经济增长的作用存在区域差异，对东部推动作用最强，中西部的推动作用较弱。“新常态”下推动中国经济发展，既需要信贷扩张形成的资本要素，更需要研发投入形成的创新要素。

| Abstract: | This paper makes an empirical analysis how credit expansion and R&D investment contribute to China economic growth from quantity and quality dimensions by using GMM for dynamic panel data method based on the inter-provincial panel data from 1998 to 2012. The result shows that: nationwide, both of credit expansion and R&D investment contribute to economic aggregate growth positively, while the effect of R&D investment is stronger than that of credit expansion. R&D investment promotes the improvement of economic quality, but credit expansion is opposite. Besides, the effects of credit expansion and R&D investment have regional disparity; it is the strongest in the east while it is inferior in the central and western regions. Promote China economy development under “new normal” background, not only need the capital factor produced by credit expansion, even need the innovative inspiration created by R&D investment more. |
