基于2013—2018年全国15省区肉牛养殖成本收益非平衡面板数据，运用非参数共同前沿分析方法中的Metafrontier-Malmquist指数对东、中、西部肉牛全要素生产率及其分解的时空分异特征进行实证研究。结果表明：东部技术效率水平最高，达到0.845 3，其次为中部的0.770 9，西部最低，仅为0.727 1；中部对东部技术效率表现出追赶趋势且两者差距逐渐减小，西部与东部、中部的技术效率差距逐渐扩大，西部技术效率水平持续下滑。东部肉牛生产共同前沿全要素生产率增长速度低于西部地区但高于中部地区，技术效率降低对全要素生产率增长表现出消极效应；西部肉牛生产共同前沿全要素生产率年均增长率是唯一增长的区域，主要源于技术进步；中部年均增长率处于最低水平，原因是技术效率的降低直接导致全要素生产率降低。应加大肉牛产业科技投入与推广力度，重点扶持西部地区肉牛产业，深入挖掘和激发西部地区肉牛养殖潜力，充分发挥东部和中部地区的产业优势，展现优势区域的示范带头作用，推动全国肉牛产业快速发展。
Based on an unbalanced panel data of beef cattle breeding costs and benefits in 15 provinces from 2013 to 2018, and applying the Metafrontier-Malmquist index in the non-parametric Metafrontier analysis method, this paper empirically studied the spatio-temporal differentiation characteristics of the total factor productivity (TFP) and its decomposition of beef cattle in eastern, central and western China. Results show that the technical efficiency level in the east is the highest, reaching 0.8453, followed by the middle with the value of 0.7709, and the lowest in the west with the value of 0.7271. The technical efficiency in the central region is catching up with that in the eastern region, and the gap between the two is decreasing gradually. The gap between the technical efficiencies in the western region and the eastern and central regions is gradually expanding, and the technical efficiency level in the western region continues to decline. The growth rate of the TFP in the Metafrontier of beef cattle production in the east is lower than that in the west but higher than that in the central region. The average annual growth rate of the TFP in the Metafrontier of beef cattle production in western China is the only region that grows, mainly due to the technological progress. The annual growth rate of central China is at the lowest level, because the decrease of the technical efficiency leads to the decrease of the TFP directly. In the summary, this paper provides the following suggestions to promote the rapid development of the national beef industry: increasing the investment and promotion of beef cattle industry technology, focusing on supporting the beef cattle industry in the western region, deeply exploring and stimulating the potential of beef cattle breeding in the western region, giving a full play to the industrial advantages of the eastern and central regions, and showing the exemplary leadership role of the advantageous regions.
