全要素生产率(TFP)分析方法未考虑资本投入中蕴含的技术进步,低估技术进步对中国经济增长的贡献。基于改进的Solow模型构建技术进步测度方程,对中国1953~2011年实证分析结果表明,1953~1978年,技术进步率-0.19%,对经济增长贡献8.61%;1979~2011年,技术进步率4.43%,对经济增长贡献44.35%,技术进步是改革开放后经济增长的主要推动力。
Total factor productivity (TFP) analysis methods do not take into account the technological advances in capital investment, underestimate the contribution of technological progress to China’s economic growth. Based on the improved Solow model, a measure of technological progress is established. The empirical analysis of China from 1953 to 2011 shows that from 1953 to 1978, the rate of technological progress was -0.19%, contributing 8.61% to the economic growth. From 1979 to 2011, the rate of technological progress was 4.43 %, Contributing 44.35% to economic growth. Technological progress is the main driving force of economic growth after the reform and opening up.
