Abstract: Beef cattle industry is an important part of livestock industry in China, and it has made great contribution for increasing farmers and herdsmens economic income and improving urban and rural residents’ dietary structure. But the beef cattle industry and beef market are facing huge pressure under many factors influence. It is of significant reference for the government to regulate and control beef cattle industry to improve the technical efficiency of beef cattle breeding technology, and grasp the key influencing factors. Taking the unbalance panel data from 1998-2014 as material, this paper calculated and analyzed beef cattle breeding technical efficiency of Henan, Heilongjiang, Ningxia, Shaanxi  and Xinjiang, and its space-time distribution by stochastic frontier method, then explored those key influencing factors. The results showed that ① the technical efficiency of beef cattle breeding  was rising, the average technical efficiency was 0.813 7 from 1999-2014. There were remarkable diferences between technical efficiency of different regions. Xinjiang Autonomous Region had the highest efficiency, followed by Henan, Heilongjiang, Ningxia and Shaanxi. ② stocking density, industry strength, capital equipment, and agricultural mechanization had remarkable positive influence on technical efficiency of beef cattle breeding, while the effect of epidemic disease and feed structure had significant negative influence.

Key words: beef cattle breeding, technical efficiency, influence factor, stochastic frontier function
