项目摘要

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.

在美国，自1980年代后期以来，已经讨论了所谓的“生产力悖论”。但是，自1990年代初以来，美国的经济表现经历了9年的经济繁荣，这些日子似乎结束了。但是，在日本，主要是由于经济低迷，即使是私营公司的高管现在也面临着一个非常困难的决策问题，无论他们是否应该投资于IT（信息技术）。我们首先分析了日本行业信息化信息的当前情况，然后分析了IT对行业生产力行业的有效性。在分析中，我们定义了“知识投资”，“信息股票”及其“ Slack”的概念，并通过利用MITI正式发布的数据来估算它们。而且，将增长会计和EDA（信封数据分析）应用于新定义的数据，我们已经得出了暂定的结论，如下所示：（1）在包括纺织品，纸浆和纸张，机器r y的7个行业中，在1990 - 94年期间，（2）在同一时期内，在同一时期内，在实现了几个行业时，在同一时期内，既定的几个行业都没有促进生产力，以至于在同一时期内，这是在实现的。从这些暂定的结论中，我们可以说，在日本，至少在1994年之前，许多行业都普遍存在“生产力悖论”。由于行业至少在1988 - 89年期间，由于行业享有信息的提高，因此金融和保险行业的例外是这种例外。
