茶农生产性投资的技术效率及其影响因素实证分析——以福建安溪为例

An Empirical Analysis of Productive Investment Technical Efficiency and Influencing Factors of Tea Farmers in Anxi County,Fujian Province

以福建省安溪县茶农问卷调查数据为基础,利用随机前沿生产函数模型估计样本茶农投资的技术效率,并分析技术效率的变化规律及其影响因素。研究表明,茶农从事茶叶生产加工的时间、茶农从事茶叶生产加工的时间的平方项、茶农户主的受教育年限这3个解释变量对于技术效率的影响不显著;而茶农户主年龄、茶农主栽品种、是否接受过培训、茶农茶叶收入占家庭总收入的比例、茶农家庭拥有的茶园面积、村庄所在地类型虚变量与技术效率呈现正相关的关系;茶农家庭拥有的茶园面积的平方项、地区差异则对技术效率产生负向影响。

Based on Anxi County,Fujian Province farmers survey data,this article take it as an example,establishes Stochastic frontier production function to estimate the economic efficiency for tea production and procession,it analyzes technical efficiency change and its Influencing factors.It showed that farmers engaged in tea production and processing time,farmers engaged in tea production and processing time of the square,the tea farmers head of the household number of years of education of three explanatory variables for the impact of technical efficiency was not significant;The household head＇s age of tea farmers,tea Varieties,whether trained,tea earning percent in household income,tea plantations area,virtual variables of villages location type had positive relationship with the technical efficiency.The square of the tea area owned by farmers and the regional differences have negative effects on technical efficiency.
