农户生产无公害蔬菜的技术效率及其影响因素分析——基于山东寿光无公害黄瓜和西红柿生产的调查

摘要

According to the data from the survey for sample farms planting free-pollutant cucumber and tomato in Shouguang, Shandong, this paper calculates the technical efficiency of free-pollutant vegetable production by the methods of data envelopment analysis and stochastic frontier analysis,and analyzes the determinants of technical efficiency.Results shows as follows: the average technical efficiency of free-pollutant vegetable production is low,and the reason is the excess input and the diseconomy of scale;acquiring technological information and establishing stable sale channels have positive effects on enhancing the technical efficiency of free-pollutant vegetable production; the results obtained by these two methods are consistent.%根据2008年对山东寿光样本农户生产无公害黄瓜和西红柿的调研数据,运用数据包络分析法和随机前沿分析法测算了其生产的技术效率,分析了农户生产无公害蔬菜的技术效率的影响因素.结果表明:农户生产无公害蔬菜的平均技术效率低.主要原因是部分要素投入过剩和规模不经济;获取科技信息和建立稳定的销售渠道对提高农户生产无公害蔬菜的技术效率有显著的正效应;利用两种测算方法所得的结果具有一致性.
