An Analysis of Pig Production Efficiency and Regional Differences in China Based on Malmquist-DEA Model and Inter-provincial Panel Data

Pig production efficiency and its regional differences in China have strategic importance to the transformation of pig production mode and optimization of pig production layout in China. In this paper, Malmquist-DEA model is adopted to analyze the statistical data; TFP and its decomposition indicators of different pig breeding scale among the top ten pig producing provinces are calculated; both horizontal and longitudinal comparisons are made. Results show that among different pig breeding scales, free-range breeding scale is dominant in Hunan, small breeding scale is dominant in Sichuan, medium breeding scale is dominant in Sichuan and Hunan, and large breeding scale is dominant in Sichuan, Shandong and Jiangsu; among the provinces, pig production efficiency varies with breeding scale, and small-scale pig breeding in Sichuan, Guangdong and Hebei, free-range and medium-scale pig breeding in Hunan, medium-scale pig breeding in Henan and Yunnan, large-scale pig breeding in the rest of the provinces, have significant efficiency advantage.
