coefficient of cubical elasticity
3.In order to accurately understand &realize the electrical elasticity coefficient and its variety rule ，this paper calculate annual electrical elasticity coefficient of YunNan province and China since 1950 especially nearly 30 years， analysis the undulatory property、limitation of time and the factors which affect the electrical elasticity coefficient， synthetically evaluate the load forecast method based on electrical elasticity coefficient ，and propose the value of electrical elasticity coefficient.
4.This paper reviews the international experiences of the transformation of economy growth pattern and makes the model with general equilibrium on the basis of OLG model. In conclusion,when the economy achieve equilibrium,the intensified degree of economy growth is equal to output elasticity coefficient of labor,also is the proportion of labor reward in total output.
