| Abstract: | Information technology has always played an important role in the services sector of the U.S. economy. In recent years, however, services industries have stepped up their acquisitions of computers, telecommunications equipment, and other such products dramatically. As a result, the broad segment of the economy that can be classified as services providers now owns about 84% of the total U.S. stock of information technology items. Moreover, relative to goods-producing industries, a much larger proportion of the services sector's capital budgets is spent on information technology, revealing a significantly greater dependence by services on such technology as a factor of production. This reliance underscores technology's strategic importance in the United States' competitive challenge. With services now the predominant mode of economic activity in the United States, a productivity payback from information technology is absolutely essential to keep the economy on a longer term path of sustainable growth.So far, the services sector has little to show for its spending binge on technology. Quite simply, massive investments in information technology have failed to boost national productivity growth in the present decade. Furthermore, with manufacturing productivity now on the rebound, problems in the services sector loom increasingly large in the United States' broader competitive struggle. It is certainly not too late. New and creative applications of information technology could still enhance the productivity performance of the services sector's predominantly white-collar work force. Until that payback begins to occur, however, the role of technology spending will be under growing suspicion 3, 8, 9].In what follows, an attempt is made to provide a detailed industry-by-industry assessment of services sector spending on information technology. By way of background, the broad contours of capital formation in services industries are first examined over the post-World War II era. |
