摘要
本文分别利用数据包络分析(DEA)方法和格兰杰(Granger)因果检验法对我国1991—2004年科技投入的效率、效果进行测度。科技投入效率的实证结果表明,如果用技术进步为社会经济发展带来的效应作为衡量科技投入产出的指标,我国科技投入总体上是相对有效的,只是在投入规模上还需进行调整,以提高规模效率,进而提高科技投入的总效率;科技投入效果的实证结果表明,我国科技投入是有效的,对经济增长的贡献明显(包括经济增长数量和质量);科技投入是我国经济增长的格兰杰原因,即我国科技投入对经济增长的影响效果明显,这说明我国科技投入已经成为促进经济增长的重要手段。
The efficiency and effects of China' s Science & Technology (S&T) Investment from 1991 to 2004 is tested by the methods of Data Envelopment Analysis and Granger test of causality respectively. The results of efficiency test show that China's S&T investment is effective on the whole, if using the impacts of technological advance on the economic development as the indicator of the efficiency; but the scale of S&T investment should be adjusted to improve the efficiency. The results of S&T effect test indicate that China' s S&T investment has contributed a lot to economic growth, in terms of both economic quantity and quality; and China' s S&T investment does Granger-cause of China' s economic growth. This is a evidence which indicate that China's S&T investment has played a important role in promoting China's economic development.
