Abstract
Attempting to discuss the transactional interdependence of the ASEAN region consisting of Indonesia, Malaysia, the Philippines, Singapore and Thailand in comparison with that between the region and its adjacent countries, this paper analyzes trade flows in Southeast Asia in 1950, 1960 and 1970. The level of interdependence is measured herein by the percentage of exports and the Relative Acceptance index which is applied to international relations in Southeast Asia for the first time. Major findings are that the ASEAN countries have been relatively interdependent with one another, and that the ASEAN region has been relatively distinct from its adjacent region. The interdependence of the ASEAN region may be characterized by the heterogeneity of the level of interdependence among the member countries, rather than the lack of interdependence which has been believed.
