Abstract:The competitiveness of the swine industry in Yunnan Province was analyzed based on the relevant data of the livestock industry in the provinces (municipalities and districts) of Southwest China from 2011 to 2020, using the efficiency advantage index (EAI), and scale advantage index (SAI) and Aggregated advantage index (AAI) methods. The results showed that the mean values of EAI, SAI and AAI in Yunnan Province from 2011 to 2020 were 1.21, 2.49 and 1.74, respectively. Compared with other livestock industries in Yunnan Province, the aggregated advantage of the swine industry is lower than that of the beef cattle industry, and higher than that of the mutton sheep industry and poultry industry. Among the swine industries in the five southwestern provinces (municipalities and districts), the scale advantage of Yunnan Province is the most obvious, the aggregated comparative advantage of Guizhou province is the most prominent, and the competitiveness of Tibet is the weakest. It is recommended that Yunnan Province continue to include the swine industry as a key development object, through expanding the scale of moderate breeding, increasing the cultivation of refined pork processing enterprises and products development, so as to realize the transformation from scale advantage to efficiency advantage.
