不同规模农户冬油菜生产技术效率及影响因素分析——基于随机前沿函数与1707个农户微观数据
Winter rapeseed's technical efficiency and its influence factors:Based on the model of stochastic frontier production function and 1 707 micro-datas of farmers
摘要
Abstract
Based on the model of stochastic frontier production function, this paper made an empirical analysis on winter rapeseed's technology efficiency and its influence factors with a sample of 1707 farmers in different production scales in China. The study showed that the labor output elasticity of rapeseed production was 0.153 5, which meant it was still in the labor-intensive phase,and presented a "U" trend between rapeseed-cultivation scale and technical efficiency. If the technical inefficiency was eliminated, the average output of rapeseed would increase by 24. 1%. The efficiency loss function showed that,for the small-scale producers, householders' age( - 3. 225, the estimated coefficients, the same below) .labor force of engaged in rapeseed( - 0. 501), the times of technology training ( - 3. 448), income levels ( - 0. 567) and subcontract of farmland (- 0. 366)had positive impact on technical efficiency, meanwhile the scale of rural households(0.476),level of educations.143) had negative effects. Whereas for the ultra-large-scale producers, the level of education(-0.251),the size of rapeseed cultivation(-0.171)and subcontract of farmland(-0.540) had positive impacts on technical efficiency, but householders' age(0. 028), the times of technology training (0. 240), outward employment or not (0.370)had negative effects.关键词
