本文引入希克斯要素偏向型技术进步的思想推导了劳动收入比重变化率的分解公式，发现劳动收入比重的变化率取决于三个因素：乘数效应大小、资本深化的速度及劳动（或资本）节约型技术进步的大小。在此基础上，利用动态最小二乘法估算了我国劳动密集型和资本密集型部门的劳动边际产出弹性，并对这两类部门1990-2006年劳动收入比重变化进行分解。研究发现：资本深化能提高劳动收入比重，但大于0小于1的乘数效应缩小了其对劳动收入比重的正向拉动作用，而劳动节约型技术进步则是两类部门劳动收入比重下降的最主要原因。为了稳定劳动收入比重，应该在看到资本深化长期效果有限的同时，关注资本节约型技术进步的作用，重视发展劳动密集型产业。

Based on the theory of Hicks factor-biased technical progress, this paper deduces a formula to decompose labor share＇s change. It is found that the change depends mainly on three factors ： multiplier effect, capital deepening and the progress of labor（or capital-） saving technology. With these findings, we use dynamic least squares （DLS） to estimate the elasticity of labor marginal output in China＇ s labor-intensive and capital-intensive sectors, and then decompose their labor share＇ s change during 1990-2006. The result shows that capital deepening will increase labor share, while multiplier effect whose value is between zero and one will contract this positive drive. And the key cause of a declining labor share in both sectors is labor-saving technical progress. In order to stabilize the labor share, we should understand that there is a limit to the long-term influence of capital deepening and pay more attention to the capital-saving technical progress and the development of labor-intensive industries.
