内容提要:本文对改革开放以来的劳动收入份额变动按就业、报酬和产出进行了分解,发现劳动收入份额的变动主要由报酬和产值效应相向变动所得的净效应决定,而就业变动效应的影响相对较小。同时,区分名义和实际劳动收入份额的分解情况后,发现剔除价格因素的实际劳动收入份额变动及其分解更能反映中国国民收入分配格局变动的真实情况。利用水平和差分方程,本文不仅考察了劳动收入份额的决定因素,而且分析了劳动收入份额变动的影响机理,发现各变量通过三大渠道对劳动收入份额变动的影响机理尽管各不相同,但均比较符合理论假说和现实预期。其中,产业结构变量的影响最大,其产出负效应超过其他两种效应,对劳动收入份额产生了向下的冲击作用,从而支持劳动收入份额的“库兹涅茨事实”。
关键词:劳动收入份额、就业变动效应、报酬变动效应、产出变动效应
Decomposition and Mechanism of Movement of China's Labor Income Share Zhou Minghai (University of Nottingham Ningbo China) Abstract: This paper decomposes the movement of labor income share since China's reform and opening up into employment, compensation and output effects.We find that the movement of labor income share is mainly determined by the net effects of the opposite movement of compensation and output effects, and the employment effect is relatively small Meanwhile, this paper distinguishes the decomposition of nominal and real labor income share, and finds that the real labor income share reflects the current situation of national income distribution of China.By using level and difference equations, the paper not only discusses the determinants of labor income share, but also analyzes the mechanism of movement of labor income share.We find that the affecting mechanisms of each variable on labor income share through three channels are different, but are consistent with the theoretical hypothesis and practical prediction.The output effect of industrial structure variable exceeds the other two effects, and the overall effect of industrial structure has the largest impact on the decrease of labor income share, which supports the “Kuznets fact” of movement of factor income share.
