“…Our results are mostly consistent with expectations. Over the decades, the Korean government have implemented various cost‐reduction policies to boost price competitiveness of Korean rice in the global rice market (Jeon & Kim, 2018; KREI, 2020). Such policies focus mainly on enhancing irrigation system, mechanization, consolidation of rice field, crop specialization, and farmer education.…”

Objectives of our study are to develop a procedure for intertemporal comparison of both technical and cost efficiency and estimate farm efficiency for the Korean rice industry from 2003 to 2017. The newly developed base‐year procedure excludes frontier shift and price effects from the standard procedure for intertemporal comparison. An adjusted central limit theorem for sample T‐tests is applied to avoid potential bias from efficiency scores by the Data Envelope Analysis. Our empirical results show that the two procedures yield different scores and trends. The standard approach indicates declining efficiency, while the base‐year method shows overall improvement in farm efficiency.
