The Crude Palm Oil (CPO) industry is one of the plantation commodities that has a strategic role in Indonesia's economic development. The number of companies and CPO production is always increasing, but the concentration of the industry that always decreases every year makes it important to analyze the factors that affect the concentration of the CPO industry in Indonesia. The data period used in this study was from 2001 to 2020. In this study, data sources were obtained from the Central Bureau of Statistics (BPS) Indonesia, Word Bank, and UN Comtrade. The data analysis method used is regression analysis of the Error Correction Model (ECM). The results showed that technical efficiency has a negative and significant relationship both in the long and short term to the concentration of the CPO industry. Competitiveness in the long term has a positive and significant relationship, while in the short term it is negative but not significant to the concentration of the Indonesian CPO industry. In the long run, the relationship between RSPO and Indonesia's CPO industry concentration tends to be negative but not significant, while in the short term it shows a significant influence. World CPO prices, both long-term and short-term, provide a positive and significant correlation to the concentration of the Indonesian CPO Industry. Indonesia's CPO exports in the long and short term have a negative and significant effect on the concentration of the Indonesian CPO industry.
