摘要
生猪是我国畜牧业第一大产业,也是我国肉类食品的主要来源,在我国农民收入中占有较高的比重。提高我国生猪的生产能力,对于稳定物价、保障肉类消费具有重要的现实意义。本文利用DEA技术和Malmquist指数的方法,对我国1991-2005年,不同地区生猪散户养殖的生产率(TFP)增长、技术变动和技术效率,2001-2005年这一时间段内,我国生猪规模生产的生产率增长、技术变动和技术效率变动进行了分析研究。研究结果表明:技术水平是制约散户养殖生产率增长的关键因素;而生猪规模生产的效率下降主要受技术效率衰退和技术水平下降的共同影响,但技术效率衰退影响更大;我国中、西部地区在生猪散户养殖方面拥有一定的比较优势,而我国东部地区则在生猪规模生产方面占有较强的比较优势。
As the main source in the meat foodstuff, live pig is one of the biggest industries in stock raising of China, and possesses upper proportion in farmer income. Therefore, improving the throughput of live pig has important practical meaning for stabilizing price and ensuring meat consumption. By using DEA technology and Malmquist Index, this paper analyzed the TFP increase, technology change and technology efficiency of live pig breeding individual in different region of China from 1991 to 2005. At the same time, the paper also analyzed those of live pig breeding on a large scale from 2001 to 2005. The research indicated：the technology level of live pig breeding individual was the key factor which restricts the increasing of live pig productivity of China; the efficiency depression of live pig＇ s scale production was influenced by the technology efficiency and technology level depression at the same time, while the latter was more effective; there were some comparative superiorities of live pig breeding individual in central and west China; there were more comparative superiorities of live pig breeding on a large scale in east China,
