基于Translog生产函数的北京市西瓜最优种植规模研究

Studies on Optimal Watermelon Cultivation Scale in Beijing based on Translog Production Function

农业适度规模经营是未来农业的发展方向,本文以规模经济理论为基础,通过建立Translog生产函数模型和DEA包络分析法,最终得出以农户为经营主体的北京市西瓜最优种植规模为6670m2(10亩)。除此之外,研究还发现种植户年龄及文化程度对西瓜种植具有显著影响,但随着农村人口老龄化日趋严峻,培养新型职业农民可以衔接西瓜种植的"断层"。

Moderate agriculture scale management is the development direction for agriculture in future.This paper took scale economics theory as the basis,and found out the optimal watermelon planting scale in Beijing was6670m2by establishing Translog production function model and using DEA envelopment analysis method.Besides,this study also discovered that age of farmer household and education level had significant influence on watermelon planting.But along with the aging of rural population becoming worse day by day,train professional farmer of new type could help to link up the2generations engaged in watermelon planting.
