| 中文摘要: |
| 本文基于CES生产函数，从技术进步偏向的定义出发，概念上厘清增强型、偏向型、节约型技术进步的区别和联系，比较希克斯偏向型技术进步和哈罗德技术进步的异同点，并利用中国1978-2008年的时间序列数据估算要素替代弹性、要素增强型技术进步和偏向型技术进步。结果表明：资本与劳动的替代弹性小于1，技术进步方向总体上是资本偏向型的。研究说明选择怎样的技术进步偏向和速度对于中国至关重要，它是增长与分配的平衡器。 |
| 英文摘要: |
| This paper clarifies the concepts of factor-augmenting, factor-biased and factor-saving technical change by tracing back to the original definitions and using CES production function. Make a comparison between Hicks’ factor-biased technical change and Harrod’s factor-biased technical change. Use time-series data of China from 1978 to 2008 to estimate elasticity of substitution between capital and labor, then compute the value of factor-augmenting and factor-biased technical change. The results show that in the sample period elasticity of substitution between capital and labor is less than 1, and in most years the direction of technical change is factor-biased. |
