Japanese and American scholars, working as a team, compared the semiconductor industries of the two countries as to technology, finance, forms of business organization, industrial policy and relations with government. Although not everything is crystal clear-even to the researchers-there is a remarkable amount of information in this book, and Professor Okimoto makes a yeoman effort to determine where each industry is stronger. There is no way for this kind of study to be completely up to date, but there is enough here to help one appraise changes as they occur.
