中文摘要：

通过构建CES生产函数和C—D道格拉斯生产函数的组合模型，分析了1979--2007年劳动和资本的密集程度及资本投入、劳动投入、科技进步对经济增长的贡献。研究结果表明：科技进步年均增长率较低，劳动密集程度大于资本密集程度，科技进步对经济增长的贡献率平均值为35．5％，我国经济主要依靠资本和劳动等生产要素投入，属于传统的粗放型经济增长模式。

英文摘要：

By establishing a combined model which consists of a CES production function and a Cobb-Douglas production function, this paper aims at investigating the effects of the labor scales, capital scales, capital inputs, labor inputs and scientific and technological progress on the economic growth from 1979 to 2006. The result indicates that the annual growth rate of scientific and technological progress is lower than others, and the contribution rate of scientific and technological progress is 35.5%. It is also shown that the labor scales are larger than capital scales. Finally it is shown that China＇s economic growth mainly depends on capital and labor inputs and other factors of production, which belong to the traditional extensive economic growth mode.
