摘　　要：基于协整理论,对我国1987-2006年的R&D投入和经济增长之间的关系进行了实证研究。首先对时间序列R&D投入和GDP进行了平稳性检验,结果表明两者的对数序列均为一阶单整并且存在着协整关系;构建了二者的长期均衡方程和误差修正模型,用来描述二者之间的长期和短期动态均衡;最后,根据研究结论对于我国如何加大技术创新投入推动经济发展提出了几点建议。Based on co-integration theory, this paper analyses empirically the relationship between China＇s R＆D input and economic growth in the period of 1987--2007. Firstly it verifies the stationary test, Granger Causality test and co-integrating test between the logarithms of time serial variables of R＆D input and GDP. The results show that the variables are all integration I （1）, and there exists the stationary linear co-integrating relationships; and then the long-and short-run relationships are described by the long-run equilibrium equation and the ECM respectively. On the bases of research results at last, some suggestions are put forward for China how to increase R＆D input for driving its economy development.
