Abstract: This paper constructs a normalized energy CES production function with factor-augmenting technical progress and a normalized supply-side system to measure the elasticity of substitution and the rate of technical progress of China from 1980-2011 using DE non-linear optimization method by converting the four equation of supply system to one equation. We find two important results. First, the energy CES function with (KE)L form is more suitable for China. Second, the elasticity of substitution between capital and energy is 0.345, and the rate of energy-augmenting technical progress is 2.6%.
