The impact of ICT progress at the inter-industry structure

A comparative study of Japan, the U.S., and China using IO tables

Abstract

The purpose of this study is to conduct a comparative analysis of Japan, the U.S., and China about inter-industry structure between ICT-producing and ICT-using industries by observing data from Japanese and international input-output tables. In the 1990s, ICT-using industries and producing industries progressed, with each being inseparable from the other. Subsequently, as globalization progressed in the 2000s and beyond against a “leakage to import” background, the ripple effect of the “ICT-using industries” toward the promotion of the “ICT-producing industries” weakened. Furthermore, this is mainly due to increased inputs from China, South Korea, etc. This is a distinctly different trend from that in the U.S., which increased domestic input while utilizing global supply systems.
