| 摘 要： | 建立了R＆D投入与自主创新能力关系的模型，并以1991-2003年的我国大中型工业企业统计数据为基础，运用计量经济学中的协整分析方法，对R＆D投入强度与自主创新能力间的关系进行了实证研究，发现“二者存在长期稳定的均衡关系，不同时期分别出现不很明显、明显、双向明显的因果关系”，并针对提高自主创新能力提出一些前瞻性的对策。

| Abstract: | The Paper establishes the model about R&D input intensity and the independent innovation ability. Based on the statistical data between 1991 and 2003 of the big and medium-sized industry business enterprise of our country, this paper analyzes the relationship between R&D and the independent innovation ability by using cointegration analysis in the econometrics, and then discovers that there is the long-term's stable equilibrium relation between them. In different periods, there is unobvious and obvious and obvious double-directions causality. At last, the paper brings up some forward-looking suggestion according to improving the independent innovation ability. |
