Vegetable Production Efficiency and Influencing Factors in Fujian Province
-
摘要: 福建省作为我国蔬菜生产大省,具有良好的区位优势和气候优势,但福建省蔬菜产业发展层次和水平并未与资源、产量相匹配。通过对福建省5个地市的蔬菜种植户进行300份问卷的调查和调研,采用DEA-BCC法对蔬菜生产的资本和劳动投入及产出进行实证分析,引入农户及家庭特征、蔬菜生产条件、制度及政策三方面进行影响因素分析。结论认为,蔬菜种植农户的资源配置能力和资源使用效率整体水平不高,蔬菜生产效率与户主受教育年限、种植技术、物流水平及是否购买农业保险等因素有关。Abstract: Fujian, a province with large vegetable production, possesses good location and climate advantages, with which the development of vegetable industry in Fujian was not yet consistent. Empirical analysis on vegetable production capital and input-output was conducted with DEA-BCC based on 300 questionnaires from vegetable growers in 5 cities of Fujian, and three factors were considered, including characteristics of farmers and their family, vegetable production conditions and restriction, and the corresponding policy. The results showed that the resources allocation ability and resources utilization efficiency of vegetable growers were generally not high. The vegetable production efficiency was affected by the grower's education level, growing technology, logistic system, agricultural insurance, and so on.
