Description:
<jats:p>To establish economic and monetary union (EMU) in East Asia, deepening regional integration through international trade is important. The economic interdependence (one of the important criteria for regional integration) study, using macro data does not reflect the indirect effects generated by interactions between different production sectors and different countries. We use the international input‐output (IIO) framework to study the economic interdependence at both macro and production sector levels. We refine the existing methods to reflect exogenous country effect and size effect of the economy. Our study suggests that establishing EMU in East Asia appears to be somewhat premature. However, we can be more optimistic for regional integration at the production sector level in East Asia when including Japan, which will create a basis for EMU in the region.</jats:p>
