Technical efifciency and its determinants in China’s hog production

摘要

China’s hog production is undergoing a great transformation due to the soaring demand and changing raising system. Re-garding the essential role of pork in Chinese diet, a systematic analysis on the productivity and efifciency of hog production can provide signiifcant implications for policy makers. This paper investigates the productivity and efifciency of hog pro-duction and the determinants of technical efifciency in China using a household level panel data (2004–2010). A stochastic frontier translog production function with scaling property in inefifciency term is adopted for hog production analysis, and the determinants of technical efifciency are incorporated in a one-step estimation using maximum likelihood estimation. Our results show that the average technical efifciency of hog production in China is 0.5914. More importantly, we ifnd that specialized farmers have higher technical efifciency than others, and technical efifciency in the eastern region is higher than that in Central and West China.
