- 摘要:
- 基于陕西、山东两省的农户调研数据,运用超越对数随机前沿生产函数分析矮化栽培模式下苹果生产要素的产出弹性,替代弹性及影响因素。结果表明:农户健康状况和果树种植时间对机械-劳动力替代弹性具有正向影响,土地类型对机械-劳动力替代弹性具有负向影响;果园面积对机械-肥料替代弹性具有正向影响,土地类型和土地质量对机械-肥料替代弹性具有负向影响;劳动力年龄、有无一技之长、每年投入时间对劳动力-肥料替代弹性具有正向影响,土地质量对劳动力-肥料替代弹性具有负向影响。
- Abstract:
- Based on survey data of farmers in Shaanxi and Shandong Provinces,this study used beyond-log stochastic frontier production function to analyze the output elasticity,substitution elasticity and influencing factors of apple production factors under dwarf cultivation mode.The results showed that the health status of farmers and the time of planting fruit trees had a positive effect on the elasticity of mechanical-labor substitution,and the land type had a negative effect on the elasticity of mechanical-labor substitution;the orchard area had a positive effect on the elasticity of mechanical-fertilizer substitution.Land quality had a negative effect on the elasticity of mechanical-fertilizer substitution;the age of the labor force,the length of a skill,and the annual investment time had a positive effect on the elasticity of labor-fertilizer substitution,and land quality had a negative effect on the elasticity of labor-fertilizer substitution.
