摘要
建设农业强国,首要任务就是要确保国家粮食安全,农户生产效率事关国家粮食产量稳定和粮食战略安全。利用江苏水稻种植户调查数据,基于超越对数随机前沿生产函数模型测度农户生产效率,在此基础上从农业生产性服务供给视角考察农业产业链发展对农户生产效率的影响,并关注农户生产投资规模、生产投资结构和正规信贷获得在其中的影响机制。研究表明:样本农户平均生产效率为0.87,总体较高,但仍存在13%的生产效率损失;农业产业链服务对农户生产效率具有显著促进作用,且对小规模农户的促进作用更明显;农业产业链服务通过激励农户增加土地经营规模和单位土地农机投入,促进农户以机械投入替代劳动投入、以扩大土地经营规模替代购置农机,以及提高农户正规信贷获得促进农户生产效率提升。提出强化农业产业链服务水平、因人制宜供给农业产业链服务、创新农村金融产品供给等政策建议。
For the strong agricultural country building,the primary task is to ensure national food security.The production efficiency of peasant households is highly related to the stability of national grain output and grain strategic security.Based on the survey data of rice farmers in Jiangsu province,the production efficiency of farmerswas measuredbased on the translogarithmic stochastic frontier production function modelin this paper.Furthermore,the influence of the development of agricultural industry chain on the production efficiency of farmers was investigated from the perspective of agricultural productive service supply.The influencing mechanism of the scale of production investment,production investment structure and formal credit access of farmers on production efficiency of farmerswere also explored.It was found that the average productivity of the sample farmerswasas highas 0.87,although there was still a productivity loss of 13%.The service of agricultural industry chain had significant promoting effects on the production efficiency,especiallyfor small-scale farmers.By encouraging farmers to increase the scale of land operation and agricultural machinery input per unit of land,agricultural industry chain services promoted farmers to replace labor with machinery input,expanded the scale of land operation instead of purchasing agricultural machinery,and improved farmers'access to formal credit to promote their production efficiency.Policy suggestions were put forward to strengthen the service level of the agricultural industry chain,to adjust the supply of agricultural industry chain services to different conditions,and to innovate the supply of rural financial products.
