摘要
本文利用中国1998—2011年30个省市面板数据,通过动态面板模型比较分析了不同执行部门和类型的R&D投入对全要素生产率的影响。研究结果表明,虽然我国R&D投入总体上会显著改善全要素生产率,但根据R&D执行部门和R&D类型的不同其效果存在显著差异:在执行部门R&D的效果比较中,工业企业最强,余下依次为科研机构和高等学校;在不同类型研发活动比较中,试验发展的效果最强,余下依次为基础研究和应用研究。因此,为了进一步提高研发效率,R&D投入结构调整和研发体制改革仍存在很大空间。
In this paper, we utilize dynamic panel model to perform comparative analysis of the effects of different sectors and types of R＆D on TFP with panel data of 30 provinces and cities in China from 1998 to 2011. The results show that, although our R＆D investment will significantly improve the overall TFP, but there are significant differences based on R＆D executive sectors and R＆D types： the effect is the executive arm of R＆D, the indus- trial enterprises of the strongest, and the remaining were R＆D institutions and colleges; In comparing different types of R＆D activities, the strongest effect is experience development, and then basic research and applied research. Therefore, in order to get fur- ther improvement on the efficiency of research and development, it is still a long way to go with R＆D investment in the restructuring and reform.
