A Three-Stage DEA-Based Efficiency Evaluation of Broiler Breeding in China

초록

Broiler chickens are one of the essential meats for residents in China. To analyze and improve the efficiency of broiler chicken breeding and to promote the industry's healthy and stable development is of great significance, improving international competitiveness in China. The three-stage data envelopment analysis (DEA) model estimated the production efficiency of broiler breeding in 13 provinces of China in 2020. The results showed that China's broiler production efficiency was generally at a low level, that the average value of technical efficiency for Stage 1 was 0.595, and that there are differences between efficiencies of the regions. After removing facts about the environment and random interference, the average value of technical efficiency for Stage 3 was 0.630, and the efficiency in most areas had increased. The impact of per capita GDP and market openness on broiler production efficiency was not noticeable, but agricultural support affected broiler production efficiency. Therefore, this study puts forward countermeasures, such as strengthening investment in science and technology and actively cultivating and introducing high-quality breeds, promoting the development of appropriate-scale broiler chicken breeding according to local conditions, and we suggest increasing government support to improve the scale of breeding.
