THE DEVELOPMENT OF REGIONAL INTEGRATION IN EAST ASIA: FROM THE VIEWPOINT OF SPATIAL ECONOMICS

摘要

This paper examines the recent evolution of regional integration in East Asia, and discusses the prospects and tasks of further integration. After an overview of the globalization and regional integration trend in EU, NAFTA and East Asia during the past half-century, we introduce the basic framework of spatial economics, often called the new economic geography. In terms of globalization and regional integration, it is important to examine the general effects of decreasing transport costs (broadly defined) on spatial distribution of economic activities. Given this theoretical framework, we examine the changing economic interdependency within East Asia, as well as that between East Asia and the rest of the world over the last three decades. Next, we focus on regional diversity and disparity in East Asia. Finally, we compare the regional integration in EU with that of East Asia, and examine the tasks and prospects of further promotion of East Asian integration.
