Structural Analysis of Global Supply Chains

The recent fury of the new coronavirus was brought about by the rapid expansion of the movement of people and the distribution of goods around the world due to economic globalization. As a result, there was no choice but to reduce or suspend production around the world, exposing the shortage of raw materials represented by semiconductors. Furthermore, with the Russian invasion of Ukraine that began in late February 2022, Western countries imposed economic sanctions on Russia, and the impact has brought about serious instability in the production and distribution of energy and grains. It became clear that Russia had a certain presence in the international division of labor. In this way, it has become an important issue to grasp the reality that economic ties between nations have expanded and supply chains have become globalized, and to strengthen economic security. International input-output analysis is the economic method to clarify the basic structure. In this paper, based on the research results that I have been working on, I would like to clarify the development of the international division of labor structure and analyze the relationship between the economy and the environmental load (carbon dioxide emissions). Due to data limitations, the analysis will mainly focus on the period from 1985 to 2012, but by looking at the global economic structure before the emergence of the new coronavirus, we will explore the policy implications of Japan's external economy in the post- corona era.
