摘要: 本文推导了资本回报率的计算公式,从资本深化和技术进步的视角对资本回报率的变动进行了分解,发现影响资本回报率变动的主要因素有:乘数大小、资本深化和技术进步。利用1980—2009年数据计算了中国的资本回报率,估算了资本的边际产出弹性,并对资本回报率的变动进行了分解。实证研究发现,中国的资本回报率并没有随投资的增长而降低,资本深化虽然导致了资本回报率的降低,且乘数放大了这种效应,但技术进步却提高了资本的边际产出,从而使得中国的资本回报率处于一个稳定水平。

关键词: 资本回报率, 资本深化, 技术进步

Abstract: This paper derived the formula for calculating the return on capital,analyzed the transition of capital return based on capital deepening and technical progress,and found that the size of the multiplier,capital deepening and technical progress were the main factors to affect the rate of return.Using data from 1980 to 2009 in China,this paper calculated China's capital return,estimated the elasticity of marginal product of capital,and decomposed changes in capital return.Empirical study showed that China's capital return did not decrease with the growth of investment.Although the return on capital was lowered by capital deepening,and multiplier amplified this effect,technical progress increased the marginal product of capital,which kept China's capital return on a stable level.

Key words: rate of return on capital, capital deepening, technical progress
