Abstract: This paper examines factors influencing agricultural land-use efficiency among 35 ethnic minority groups in Vietnam during the 2010–2018 period. A hybrid approach comprising the Difference-in-Difference model with Propensity Score Matching (DID_PSM) is adopted to examine the effect of different land sizes, land elevations, and land tenure on land-use efficiency. The results show that: (1) land size and agricultural production form an ‘U-shaped’ relationship; (2) farming on high land decreases efficiency by around 7.7%–8.0%; (3) farmers purchasing or hiring land in long-term are 7.3%–8.2% more efficient. The paper also discusses typical land characteristics of mountainous areas including steep and fragmentation related to the three comparing factors. From these results, implications are made for Vietnamese authorities about ‘land accumulation’ policies and other ‘farming on elevation’ techniques.
