Measurement of Efficiency and Productivity Change of Durian in Thailand

Thailand is the number one country in crop production and durian exports, with the highest recorded export value of nearly 2,816.9 million USD in 2020. Based on a literature review, this study used the Data Envelopment Analysis (DEA) method to measure the production and scale efficiency in Thailand's durian orchards. The Malmquist index was used to analyze durian productivity in different regions of Thailand. The analysis was based on secondary data on essential factors used in durian production in Thailand collected between 2011 and 2020. The findings indicate that the average index of production efficiency changes, in terms of technology change, real technical performance changes, efficiency changes per size, and productivity changes in durian production, were found to be 1.113, 1.040, 0.988, 1.128, and 1.158, respectively. The technology change index and the change in productivity of the central region scored higher than other areas, corresponding to farmland, yield area, and durian yield.
