    摘要:

    基于江苏省552户种植业家庭农场的微观调查数据,利用超越对数随机前沿生产函数和技术效率损失函数,在测度家庭农场粮食生产技术效率的基础上,实证分析农业补贴对粮食生产技术效率的影响。研究结果表明:江苏省家庭农场粮食生产平均技术效率为0.814,家庭农场粮食生产存在18.6%的技术效率损失;与机械、自有劳动力相比,农资这一投入要素的产出弹性最大;补贴对家庭农场粮食生产技术效率存在显著负向影响。分组回归结果显示技术效率随经营规模增加而递增,补贴对粮食生产技术效率的影响存在显著规模差异。为促进家庭农场健康发展,应推动粮食生产技术转型升级;改进补贴发放方式和标准;采取多元灵活的补贴方式,提高补贴的指向性、精准性和实效性,发挥补贴对粮食生产技术效率的促进作用。

    Abstract:

    Based on the micro-survey data of 552 family farms in Jiangsu Province,the effects of agricultural subsidies on grain production technical efficiency were empirically analyzed by using the trans-logarithmic stochastic frontier production function and technical efficiency loss function based on measuring grain production technical efficiency of family farms.The results show that the average technical efficiency of grain production on family farms in Jiangsu province is 0.809,and there is a loss of technical efficiency of 19.1% in the actual production process of family farms. Compared with machinery and self-owned labor,the output elasticity of the input factor of agricultural capital is the largest.Subsidies have a significant negative impact on the technical efficiency of food production on family farms.The results of grouping regression shows that the technical efficiency increases with growing scale of operation,and there is a significant scale difference in the impact of subsidies on the technical efficiency of grain production.In order to promote the healthy development of family farms,we should pay attention to promoting the transformation and upgrading of grain production technology,prioritize subsidy payment,adopt diversified and flexible subsidy methods,improve the orientation,precision and effectiveness of subsidies,and give full play to the role of subsidies in promoting the technical efficiency of grain production.
