Are the Complementary Relationships between Transportation and Communications for Industrial Uses Dominant? A Case Study for Asian Countries

Only a few studies have been conducted to identify the relationships between transportation and communications industries - mainly in developed countries, although intermediate uses consumed more than half of the products of those two industries in developing countries as well. Therefore, this study explores the relationships between transportation and communications from the industrial perspective, using multiple-year cross-sectional I-O data for Asian countries (China, India, Indonesia, Japan, Korea, and Taiwan) where the data are available. The authors conducted Spearman correlation analysis for the transportation and communications industries (each disaggregated into manufacturing and utilities sectors as well as overall), with respect to the direct input coefficients and the total coefficients calculated from the I-O data during the 1995-2005 timeframe. Then, the correlation results were interpreted and compared with those of the developed countries (France, Germany, Italy, Netherlands, the U.K., and the U.S.). The results show that for the direct inputs to other industries, the relationship between transportation and communications can be either complementarity or substitution. However, the complementarity relationship is more dominant in Asia than in Europe and the U.S. For the industry outputs required for the final demand, the complementarity relationship between the two industries appears to be very strong in most of the countries.
