| Research Abstract |
In the United States, the so-called "Productivity Paradox" has been discussed since the late 1980's. U.S. economic performance, however, has experienced a 9-year long economic boom since early 1990's, and the discussions seem to end these days. But, in Japan, mainly due to a prolonged economic slump, even top executives of private companies are now facing a very difficult decision problem whether they should invest in IT (Information Technology) or not.
In this research; we first analyzed present situations of informatization of industries in Japan, and then effectiveness of IT on productivity industry by industry. In the analysis, we defined concepts of "Informatized Investment," "Informatized Stock," and its "Slack", and estimated them by making use of MITI's officially published data. And, applying methods of growth accounting and EDA (Envelope Data Analysis) to the newly defined data, we have reached tentative conclusions as follows : (1) in 7 industries including Textile, Pulp and Paper, machine r y, Informatized investment did not contribute increase in productivity during 1990-94, (2) during the same period, Slacks on Inforrnatized capital were observed in several industries, which means that inefficiencies existed in these industries.
From these tentative conclusions, we can say that, in Japan, "Productivity Paradox" prevailed in many industries at least until 1994. The exception is the case of Finance and Insurance industry in the sense that industry enjoyed the increase in productivity due to Informatized Investment at least during 1988-89.
