Abstract: The orderly development of labor force-energy-economy is the key to realize the sustainable development of economy. Economic system is basically in line with the characteristics of dissipative structure, entropy value can be used to measure the dynamic change of the system order degree. This paper constructs three comprehensive labor input, energy consumption and economic development indexes set from multiple dimensions, and utilize gray relational entropy model to analyze the order degree of labor force-energy-economy and between each two of them from 1990-2010 in China. The results show that: in the sample period, from the aspects of the overall, the entropy value of labor force-energy-economy system wanders up and down at zero, in other words, the development trend of the system is not clear. From the aspects of different periods, the four curves of Labor input and economic development, energy consumption and economic development, labor input and energy consumption and labor input, energy consumption and economic development before 1999 fluctuate comparatively large, and fluctuation levels off after that. From the aspects of different curve, the entropy value one between the labor input and the economic development fluctuates largest, and the curve of energy consumption and labor input fluctuates relatively stable, whose order degree is relatively better.
