摘要：
The objective of this paper is to examine the contribution of IT investment to productivity growth in Japan. To this end, we first construct a panel data set of value added, labor inputs, IT investment, IT capital stock, and non-IT capital stock in 22 industries (including 13 manufacturing industries) from 1980-2000. We then decompose labor productivity into four terms and find that the recent slowdown in productivity is caused by the absence of a reallocation effect of labor. Further, we estimate TFP growth functions and labor productivity functions, examining network externalities of IT capital. We find that TFP growth in the 1990s is affected by positive inter-industry spillover effects from the supply side. (C) 2004 Elsevier Inc. All rights reserved.
