Regional Contributions to the Changes in Korea’s Rice Productivity

Abstract

The purpose of this paper is to analyze the regional contributions to the changes in Korea’s rice productivity for a sample of eight Korean provinces over the period 1994–2006. We calculate the national aggregate total factor productivity (TFP) level by using the share of each province’s rice output as a weight. Then, we decompose the change in the national aggregate TFP over the abovementioned period into provincial contributions. The result shows South Chungchong Province to be the largest contributor to the change in Korea’s rice productivity.
