项目摘要

This study statistically analyzes the IT investment in Japan based on the firm-level database that combines the questionnaire results with financial figures in order to derive theoretical implications in designing optimal governmental intervention for the IT-based society.Our focuses are a)finding out the determining factors of such investment, b)describing its impact on the current macro-economy, and c)estimating its effect on the economic activities in the future.In the course of our study, we conducted several questionnaire surveys and executed econometric analysis. Consistency with theoretical frameworks of previous empirical studies and macroeconomic analysis is also considered. The interim findings were presented before several academic meetings held in Japan as well as in foreign countries to receive comments and feedbacks form related researchers and policy makers.Major findings of this study include :1.IT investment of Japanese firms has failed to realize its full potential due to insufficient development of complementary management factors ;2.IT penetration reduces the perceived cost of information search and then motivates people to reduce the possibility of using the physical transportation mode over some telecommunication methods when involved in purchasing activities ; and3.IT investment in the broadcasting industry impairs the economies of scale of current business models and makes it efficient to divide it into the program production section and the program distribution section.

本研究将问卷调查结果与财务数据相结合，以企业层面的数据库为基础，对日本的IT投资进行统计分析，以期为IT社会的最佳政府干预设计提供理论指导。本研究的重点是：（1）找出IT投资的决定因素;（B）描述IT投资对当前宏观经济的影响;在研究过程中，我们进行了多次问卷调查和计量经济分析。与以往的实证研究和宏观经济分析的理论框架的一致性也被认为是。本研究的主要结论包括：1.日本企业的IT投资由于管理要素的互补性开发不足，未能充分发挥其潜力; 2. IT渗透降低了信息搜索的感知成本，从而激励人们减少使用物理交通方式的可能性，3.广播行业的IT投资削弱了当前商业模式的规模经济，并使其有效地分为节目制作部门和节目发行部门。
