ABSTRACT
The study aims to efficiency production of longan in Li district, Lamphun Province and to analyze factor to effecting to technical inefficiency of longan production in Li district, Lamphun Province. The analysis used a Cobb-Douglas production equation with stochastic frontier estimation for calculate values indicating the efficiency of production. The data used in this study was taken from Office of Agricultural Economics and used questionnaires for data collection form 100 longan farmers in Li district, Lamphun Province. The study of factor which effecting on technical efficiency longan production show that area, labor, chemical fertilizer and rain water was significant to output production.As for potassium chlorate, ground water and river were not statically significant to output production.Estimation of efficiency level shows that high efficiency level.The study of factors effecting on the inefficiency show that an increase in inefficiency caused by growing longan age because this group farmer was older and who have old trust of production, accept low technology and slow to learning. As for farmer have younger so who to be learning and accept technology cause by have knowledge and understand on longan production for highest efficiency of production.
