The focus of this research is on how the position of competitiveness of Indonesian rubber exports among ASEAN countries and the dominant factors causing the competitiveness of Indonesian rubber exports experienced a downward. Approach to measuring rubber export competitiveness uses the Lafay Index, and factors that affect the competitiveness using the Diamond model by using panel data analysis method. The results show that there has been a decline in the competitiveness of Indonesia's rubber exports to ASEAN countries, the greatest decline in competitiveness that occurred in Singapore, Malaysia, and Thailand. Factors that affect Indonesia's export competitiveness that is more dominant are a foreign direct investment, price levels, and interest rates. FDI should be directed at improving the quality of export products following the quality of ISNR and upgrading the quality of rubber export products from SIT 20, and directly more beneficial for the manufacture of goods for final consumers.


Export competitiveness, the Lafay index, diamond model.
