摘要
本文采用我国30个省份1998~2012年的数据,通过面板数据模型考察了我国R＆D投入强度和政府R＆D投入对经济增长的影响和传导机制。研究表明,R＆D强度对我国经济增长具有显著的正向促进作用;政府R＆D投入对我国经济增长具有负效应。在此基础上,本文通过面板数据模型考察了R＆D投入对经济增长的影响机制。研究表明,R＆D投入强度通过提高全要素生产率和投资率促进经济增长,政府R＆D投入对全要素生产率和投资率都有负向影响。根据上述结论,本文提出促进我国创新型国家建设的对策建议。
This paper explores the effect of R＆D intensity and government R＆D expenditure on economic growth and its transmission mechanism with the data of 1998--2012 of the 30 provinces through the panel data model. We find that R＆D intensity has positive effect on economic growth, whereas government R＆D expenditure decreases economic growth. In addition, we explore the transmission mechanism of R＆D investment on economic growth. We find that R＆D intensity can increase economic growth through the channel of its positive effect on total factor productivity and investment ratio, whereas government R＆D expenditure has negative effect on both total factor productivity and investment ratio. According to the empirical analysis results, we propose policy implications to enhance China＇s process to build the innovation-driven economy.
