摘要
利用我国7个肉羊主产省2008—2016年肉羊投入产出的面板数据,对其成本收益信息进行分析,在此基础上采用DEA-Malmquist分别从静态和动态视角对我国肉羊产业的生产效率和全要素生产率在空间分布和时序变动趋势特征进行评价。结果表明:我国各主产省的成本和收益水平有一定的差异,肉羊的收益和成本总体上均呈波动上升的趋势,成本上升的幅度大于收益增长幅度。从静态角度看,我国肉羊产业的综合技术效率较高,各主产省的纯技术效率均高于规模效率,且接近最优状态。从动态角度看,不论是我国肉羊产业在2008—2016年时序变动还是各主产省份的空间分布方面,造成全要素生产率变动的主要原因均为技术进步。可以通过提高技术进步水平、改良肉羊品种、发展适度规模养殖等方式来推动我国肉羊产业高质量发展。
By using the panel data of the 2008-2016 meat sheep and goat’s input and output from 7 main producing provinces of China,this study analyzes the cost-benefit information of meat sheep and goat,and then adopts the DEA-Malmquist Index to analyze the spatial distribution and temporal variation of production efficiency and total factor productivity of meat sheep and goat industry from the static and dynamic perspectives.The results show that there are certain differences in the cost and income levels in these main producing provinces in China.The income and cost of the meat sheep and goat are in the trend of fluctuation,and the increase of cost is larger than that of income.From the static point of view,the comprehensive technical efficiency of meat sheep and goat industry in China is relatively high,and the pure technical efficiency of each main producing province is higher than the scale efficiency and even close to the optimal state.From the dynamic point of view,whether it is the temporal fluctuation of China’s meat sheep and goat industry in 2008-2016 or the spatial distribution of the main producing provinces,the main reason for the change in total factor productivity is technological progress.The high quality development of China’s meat sheep and goat industry can be promoted by improving the level of technological progress,improving the varieties of meat sheep and goat and developing moderate-scale breeding.
