Three, the contribution rate of scientific and technological progress to economic growth

　　In recent years, the National Bureau of statistics with the relevant departments to carry out the research work of science and technology progress in quantitative measurement, introduced a set of calculation methods, namely the growth rate equation and Cobb Douglas production function combination method, the specific formula is: EA=Y- alpha K- beta LY * 100%% in EA for scientific and technological progress on economic contribution to the growth of Y is K the average growth rate of output is the average growth rate of the capital, the average growth rate for L alpha labor for the output elasticity of capital and other conditions remain unchanged, the capital increase of 1%, alpha beta for increased output% of the output elasticity of labor, that other conditions remain unchanged, labor an increase of 1%, increase in output, K beta%Y and L can be calculated by the National Bureau of statistics data and search (this press a year a year of data reduction and data, in addition to the data fo
