鄂东南农户水稻生产技术效率空间格局及影响因素研究

Spatial Patterns and Influencing Factors of Rice Farmers’ Technical Efficiency in Southeast Hubei

摘要:

运用超越对数生产函数随机前沿模型对鄂东南地区775户农户水稻生产技术效率进行测度，并基于空间自相关模型分析其空间格局，进而运用空间滞后模型（SLM）和空间误差模型（SEM）对农户水稻生产技术效率的影响因素进行计量分析。研究发现：①岗地平原区的农户水稻生产技术效率普遍高于低山丘陵区，是农户水稻生产技术效率的高-高集聚区域。②农户水稻生产技术效率在乡镇层面上存在着显著的正向空间溢出效应。③家庭人均收入、耕地质量对水稻生产技术效率有显著的正向作用；而耕地细碎化程度与农户相关特征变量对农户水稻生产技术效率有显著的负向作用，耕地经营规模与农户水稻生产技术效率则呈“倒U”型关系。因此，应从加强耕地细碎化治理与耕地适度规模经营有机结合等方面提高农户水稻生产技术效率。

Abstract:

Using the stochastic frontier model of transcendental logarithmic production function to measure the efficiency of rice production technology of 775 households in southeastern Hubei, and analyze the spatial pattern based on township scale. At the same time, using the spatial lag model (SLM) and spatial error model (SEM) to quantitative analyze the related factors of farmers' rice production technology efficiency. The study found that: (1) The efficiency of rice production in rural plains is generally higher than that in low hilly areas, which is a high-high concentration area for farmers' rice production technology efficiency. (2) Farmers' rice production technology efficiency has a significant positive spatial spillover effect at the township level. (3) The per capita income and cultivated land quality of the family have a significant positive effect on the efficiency of rice production technology; while the degree of arable land fragmentation and the related characteristic variables of farmers have a significant negative effect on the efficiency of rice production technology of farmers, the scale of cultivated land management and rice production technology of farmers Efficiency is an "inverted U" relationship. Therefore, local governments should improve the technical efficiency of rice production by strengthening the management of cultivated land fragmentation, carrying out appropriate scale management of cultivated land, transforming rice cultivation mode, carrying out actions of saving fertilizer and medicine in agriculture, strengthening the construction of social service system of agricultural production and capital accumulation of agricultural labor force. Therefore, it is necessary to improve the efficiency of rice production technology for farmers from the aspects of strengthening the management of arable land and the organic scale of cultivated land.
