Abstract
The objective of this study is to analyze the technical efficiency of in-season paddy production by farmers in Chiang Rai Province, focusing on factors affecting both efficiency and inefficiency. A survey was conducted, and data were collected using questionnaires from representatives of 300 rice farmer households in three districts: 1) Phan district, 2) Mueang Chiang Rai district, and 3) Theing district. Efficiency was analyzed using the Stochastic Frontier Approach model (SFA). The study found that factors significantly affecting the technical efficiency of rice production include the cost of rice seeds, maintenance costs, production factors, and expenses for preparing the soil. Regarding the estimation of farmers' technical efficiency (TE), it was found that rice farmers exhibited production efficiency ranging from moderate to high levels, with an average technical production efficiency value of 0.9169. This indicates a rice yield lower than the maximum efficiency level by approximately 8.31 percent. Factors such as rice field size, debt, level of education, experience in growing rice, and membership in a farmer group were found to affect technical inefficiency of rice production negatively and significantly. Increasing these factors could lead to a reduction in technical inefficiency in in-season paddy production.
