For the desire of Chinese computable general equilibrium model, we estimate the output elasticity of labor by using the econometric method and the method that the output elasticity of labor equal to the share of labor income in value added by the sector, and compare our results with the output elasticity of labor of other developing countries. The conclusion is that the output elasticity of labor is between the upper limit and the lower limit of the output elasticity of labor of other developing countries. So ,our results have higher reliability.
