省域设施蔬菜生产技术效率及其作用因素研究——以番茄和黄瓜为例

Technical Efficiency and Influencing Factors of Facility Vegetable Production in China:A Case Study of Tomato and Cucumber

设施农业对于提高土地利用率、扩大农业生产、满足居民消费需求具有重要作用。利用2011-2016年全国21个省份设施蔬菜生产数据,采用数据包络分析方法和面板Tobit模型,对省域设施蔬菜生产技术效率及其影响因素进行分析。研究发现,全国各省份设施蔬菜生产技术效率差距较大,存在波动;蔬菜生产的经济效益和当地的城镇化水平对设施蔬菜生产技术效率有正向影响;各个省份蔬菜生产规模对蔬菜生产技术效率有负向影响。

Facility agriculture plays a huge role in improving land use efficiency,expanding vegetable production and meeting the consumer demand.Based on the production data of protected vegetables of 21 provinces in China from 2011 to 2015,this paper analyzes the production technology efficiency and its influencing factors,using DEA-Tobit model.The results are as follows:First,the production technology efficiency of facility vegetable in China is quite different and fluctuating.Second,the economic benefits of vegetable production and urbanization level of vegetable production have a positive effect on the production technology efficiency of vegetable.Third,the vegetable production scale has a negative impact on the production technology efficiency of vegetable.
