Based on the input and output panel data of 25 dairy producing areas from 2004 to 2012 and using stochastic frontier analysis method, Chinese dairy industry technical efficiency was analyzed and the contribution rate of science and technology was calculated in the paper. The results showed that the technical efficiency increased year by year, the average annual growth rate was 1.23% and the technical efficiency was obvious different among different areas. The value of science and technology progress contribution rate was 50.53%, and the increase of output value in the dairy industry relied heavily on the scientific and technological progress and the feed input.
