摘要： The economic efficiency of small-scale tilapia farms in Guangxi, China were analyzed by using Data Envelopment Analysis (DEA). The mean technical (under CRS and VRS), allocative, and economic efficiencies of small-scale tilapia farms were 0.89, 0.97, 0.71 and 0.68, respectively. Efficiency analysis revealed that inefficient farms would have needed to increase production output levels by 32% to perform as well as the best practice farms. The decomposition of the economic efficiency showed that allocative inefficiency was the primary cause of economic inefficiency. There were positive relationships between economic efficiency and age, culture mode and period through Tobit regression, while experience, family members, and technology support had negative effects on economic efficiency. Lower input levels of feed quantity may help to increase the tilapia farming economic efficiency.
