摘要
在现有文献的基础上,借助CES生产函数,依据中国改革开放以来的具体数据,运用非线性最小二乘法进行实证分析,得出以下结论:技术引进和R&D投入虽然大大增加了我国技术知识存量,但并没有有效地转化为全要素生产率的提高。技术引进和R&D投入之间的比例不合理,表现出重引进,轻研发。我国急需要加大R&D投入,以增强经济发展的后劲。
Since 1978, technology importing aggregate and R＆D input of our country increase very fast. The increase of two inputs influences the TFP＇ s improving of our country. Based on current literatures, after assessing CES production function by NLS, some conclusions are drawn. Although technology importing and R＆D input add the technology and knowledge of our country, the TFP didn＇ t improve quickly. The proportion between technology importing and R＆D input isn＇ t rational. We should input more R＆D to strengthen economic ＇ s stamina.
