摘要
本文基于胡麻主产区150个县的农户微观调查数据,运用EBM与GML模型对胡麻生产的技术效率与全要素生产率进行了测算,并比较了其在不同地区与主体之间的差异。结果显示:(1)胡麻的全要素生产率短期内呈现出下降趋势,效率变化起到了明显的负面作用,而较高的劳动力投入冗余是造成技术效率降低的主要原因。(2)胡麻的生产效率整体上呈现出西高东低的地区差异,新疆胡麻的生产效率相对较高。(3)胡麻的生产效率随着生产者年龄的增加而降低,青年生产者的效率水平最高,中年次之,老年最低。为实现胡麻生产的效率变革,应当坚持好适度规模的生产经营理念,重点强化对胡麻生产者的技术培训,优化胡麻生产的空间区域布局,并有效借助土地托管等社会化服务的方式。
Based on the micro-survey data of farmers in 150 counties of main production areas of flax,this paper used EBM and GML models to measure the technical efficiency and total factor productivity of flax production,and compared the differences between different regions and subjects.The results showed that:(1)The total factor productivity of Flax showed a downward trend in the short term,and the change of efficiency played a significant negative role,and the high labor input redundancy was the main reason for the decrease of technical efficiency.(2)The production efficiency of flax was higher in the west and lower in the east,and the production efficiency of flax in Xinjiang was relatively higher.(3)The production efficiency of flax decreased with the increase of producer age,and the efficiency level of young producers was the highest,followed by middle-aged producers,and the lowest in the old.In order to realize the efficiency reform of flax production,we should adhere to the production and management concept of appropriate scale,focus on strengthening the technical training of flax producers,optimize the spatial and regional layout of flax production,and effectively make use of social services such as land trusteeship.
