Abstract: Estimating labor income share accurately is an essential prerequisite to reveal the distribution pattern of China's national income. Based on the widespread NOE perspective, this article proposes a new method, parallel calculation in two systems, to estimate China’s labor income share. The re-calculation based on the national and regional dimensions indicates that China's labor income share has been essentially maintaining above 50% level, not being significantly lower than the average level of the majority of developing countries. The variation is not just to decline but shows a typical ‘inverted U-shaped’ trend. System decomposition results further show that the rise in the share of labor income is the consequence of the joint action taken by positive GDP systemic effect and positive NOE intersystemic effect, while the decline in the share of labor income is the consequence of the interaction that relatively weak positive NOE intersystemic effect cannot suppress the relatively strong negative GDP systemic effect.
