摘要: 基于2002—2021年农业时间序列数据,构建超越对数生产函数模型并利用岭回归估计方法对农业生产各要素的产出弹性、替代弹性和相对技术变化进行实证分析。结果表明,中国农业生产要素中土地的产出弹性相对较高;要素之间的替代弹性大部分在1以上;农业技术偏向于劳动节约型变化。因此,农业生产必须因地制宜,提升农业要素空间配置,加强农业生产中技术与要素之间的匹配度,提高农业生产率,实现可持续的农业生产新模式。

Abstract: Based on the agricultural time series data from 2002 to 2021, the transcendental logarithmic production function model was constructed and the ridge regression estimation method was used to effectively analyze the output elasticity, substitution elasticity and relative technological changes of various factors of agricultural production. The results showed that the output elasticity of land in China’s agricultural production factors was relatively high. The substitution elasticity between elements was above 1. Agricultural technology was inclined to labor-saving change. Therefore, agricultural production must adapt to local conditions, improve the spatial allocation of agricultural elements, strengthen the matching degree between technology and elements in agricultural production, improve agricultural productivity and realize a new model of sustainable agricultural production.

Key words: factor endowment, output elasticity, substitution elasticity, transcendental logarithmic production function
