| 摘 要： | 研发投入对企业绩效的影响虽然广为研究,但一直缺乏微观层面的数据支持。运用2005—2007年86.6万家企业数据进行分年度和面板数据回归,实证结果表明①研发投入能够显著提高企业生产效率和盈利能力;②企业研发投入较长时间的滞后效应;③将企业规模作为调节变量引入估计模型,可以发现规模较大的企业,研发投入对企业绩效的提高反而较小。因而中国企业绩效的提升,有赖于研发投入的强度和持久度。

| Abstract: | The effect of R&D on firm performance is still concerned by scholars home and abroad.The literatures which research on the correlation between R&D and firm performance from micro-level are not adequate.The paper empirically analyzes the effect of R&D on firm performance by using manufacturing enterprises micro-panel data from 1999 to 2007.The results show that R&D has a positive and hysteretic effect on firm performance.Firm scale has negative effect on R&D and performance when introduced as regulated variable.Hence,the improvement of Chinese firm performance relies on firm scale and independent innovation. |
