【摘要】：土地细碎化和耕地地力是影响农业生产及其效率的两个重要因素。本文以江汉平原354个水稻种植户为研究对象,利用效率损失随机前沿生产函数构造了4个不同的模型,探讨了土地细碎化、耕地地力不同组合对粮食生产及其效率的影响。研究发现:土地细碎化对粮食生产存在负面影响,对技术非效率存在正向影响,土地细碎化程度高和农业劳动力投入降低,使资产配置不合理,粮食生产受到严重影响。耕地地力对粮食生产效率具有显著的正向影响,有助于提高粮食生产效率,过剩的农资投入,未对粮食生产产生正向影响且不利于耕地可持续发展。因此政府应鼓励小规模农户释放土地,提高大规模农户经营管理能力,确保生产条件;鼓励和推广新型栽培技术,引导农户合理投入农资,提高生产效率;增强高质量农田和农业基础设施建设,保障生产环境。
[Abstract]:In this paper, 354 rice growers in Jianghan Plain were studied, and four different models were constructed by using the stochastic frontier production function of efficiency loss. This paper discusses the effects of land fragmentation and different combinations of cultivated land fertility on grain production and its efficiency. It is found that there is a negative impact on grain production and a positive impact on technical inefficiency. The higher degree of land fragmentation and the lower input of agricultural labor force make the allocation of assets unreasonable and the grain production seriously affected. The cultivated land fertility has a significant positive impact on the grain production efficiency, which is helpful to improve the grain production efficiency. The surplus input of agricultural resources has no positive impact on grain production and is not conducive to the sustainable development of cultivated land. Therefore, the government should encourage small-scale farmers to release land, improve the management ability of large-scale farmers, and ensure production conditions; We should encourage and popularize new cultivation techniques, guide farmers to invest agricultural resources reasonably, improve production efficiency, strengthen the construction of high quality farmland and agricultural infrastructure, and ensure the production environment.
