中国小麦主产区农机服务效率及影响因素研究OA
Supply Efficiency and Influencing Factors of Agricultural Machinery Services in Main Wheat Producing Areas of China
"大国小农"在较长时期内仍为中国基本国情,农机服务是将现代生产要素有效导入小农户生产的重要途径,农机服务效率的提升对于小麦产业发展至关重要.本研究分别利用BBC模型和DEA-Malmquist指数分析了小麦主产区农机服务的静态效率和动态全要素生产率,在此基础上采用Tobit模型,从人力资本、研发投入和服务组织化等方面,分析了小麦农机服务效率的影响因素.研究表明,近年来中国小麦主产区农机服务综合技术效率水平中等偏上,未达到效率前沿面;农机服务全要素生产率平均整体呈现震荡提升趋势,仅有少量省份的累计全要素生产率达到了效率前沿面;人力资本和农机研发投入对农机服务技术效率的提升有正向影响,但农机合作社数量占农机服务组织数量的比例与农机服务效率呈现出反向的关系.因此,政策需要从强化提升农业机械从业人员素质、因地制宜加大农机研发投入、鼓励农机合作社高质量发展等方面促进农业机械化服务效率的提升.
"Large country and small farmers"are still the basic national conditions of China for a long period of time,and agricultural machinery services will effectively introduce modem production factors into the production of small farmers,and the improvement of agricultural machinery service efficiency is very important for the development of wheat industry.In this paper,the static efficiency and dynamic total factor productivity of agricultural machinery services in the main wheat producing areas were analyzed by using the BBC model and DEA-Malmquist index,and the influencing factors of wheat agricultural machinery service efficiency were analyzed from the aspects of human capital,R&D investment and service organization.The results show that in recent years,the comprehensive technical efficiency level of the main wheat producing areas served by agricultural machinery is medium to high,and has not reached the forefront of efficiency;the total factor production efficiency of agricultural machinery services shows an overall trend of shock and increase,and only a small number of provinces has reached the forefront of efficiency;human capital and agricultural machinery R&D investment funds have a positive impact on the improvement of agricultural machinery service technology efficiency,but the proportion of the number of agricultural machinery cooperatives in the number of agricultural machinery service organizations shows an inverse relationship with service efficiency.Therefore,the policy needs to promote the improvement of agricultural mechanization service efficiency in terms of strengthening the quality improvement of agricultural machinery practitioners,increasing investment in agricultural machinery research and development according to local conditions,and encouraging the high-quality development of agricultural machinery cooperatives.
