Abstract: For the sake of promoting the optimization of hierarchy to be adaptable to the social economy development，according to the data from 1986 to 2008，the adaptability between hierarchy and economic development is quantitatively analyzed from two aspects based on the weighted elasticity of employment，co-integration model and error correction model. Then it comes to the conclusion that hierarchy basically adapts to the demands of economic development. However there are also some imperfections in the hierarchy which include industry coordination，long-term equilibrium and short-term adjustment aspects. Finally some corresponding proposals of optimization are pointed out in the light of the conclusions.
