  This study was conducted to analyzethe determinants ofdairyfarmers’ technical efficiency in Duy Tien town, Ha Nam province by using Stochastic Frontier Analysis (SFA). Research results show that the technical efficiency of localdairy farmers reached 77.8%, ranging from 13.8% to 96.9%. To improve thetechnical efficiency, dairy farmers need to change in the input usage, such as: (i) reducing synthetic feedsand increasing green ones; (ii) paying more attention to disease prevention and treatment (i.e., veterinary cost); (iii) increasing breeding areas; (iv) moving dairy farming from residential areas to concentrated livestock areas; and, (v) scaling up the herd size to achieve the economies of scale. In addition, receiving technical support from purchasing enterprises (internal finance) and accessing banking credit (external finance) play important roles in improving technical efficiency and income of households. These are the two core activities in the agricultural value chain financing approach, howeverthis approach is still not popular in Vietnam.

  The paper introduced a methodology to estimate environmental efficiency for agricultural production by applying stochastic frontier analysis. The results estimated from this method are reliable and applicaple in reality because the method can separate noise effects from deterministic frontier and ensures the independent distribution of technical and environmental efficiency scores. The so-called environmental efficiency was defined as the ability to reduce environmentally detrimental inputs while keeping other observed inputs and output level constant. The environmental efficiency is a promising and empirical indicator for producers, consumers and decision makers to arrive atproper solutions or interventions that promote the harmonious development respecting the environment. The paper also provided an example of 199 rice farmers in An Giang province in 2014 to demonstrate the detailed steps of the measurement. The results showed that the average technical efficiency and environmental efficiency were 93.16% and 77.70%, respectively. In all cases, the environmental efficiency scores were smaller than those of the technical efficiency.
