项目摘要

The purpose of this research are to estimate the household's and business' demands for communication sevices in the 21st century, and to calculate the necessary investment cost of constructing new information infrastructures.1.Methods to estimate the potential demand for commnunication services : We categorize information into 4 levels. Level-0 (memo, short letter), leve-1 (speech), level-2 (TV,images, face-to-face communication), and level-3 (materials and books to store informations), and connect them to the household's expenditures. Our calculation shows that the household's demands for BISDN from Level-2 and -3 are lager than (]SY.left filled triangle.[)0,000 per household, if the prices of multi-media services decrease to the present price level of telephone services.2.Cost of BISDN construction : We pick up the household's demands for telephone and video watching, and business' demands for telephone, facsimile and conference, and analyzed relations between demands, price of sevices and investment cost of BISDN construction. Our calculation shows taht, if prices of BISDN are about 2 or 3 times of today's telephone charge rates, necessary investment costs are 100 trillion yens, and these costs are paied off in 10 years, and in 2025, we will have 50 trillion yens BISDN infrastructure and 100 trillion yens savings debenture.3.Cost reductions in health care services : We access the impact of telecommunications on Japanese health care. Our calculation shows that the new information technology may save 1.5 trillion yens of 20.6 trillion yens national health care costs in 1990.4.The questionnairing was conducted on 300 households to collect informations about parameters of BISDN Demand-Supply Model.

本研究的目的在于评估家庭与企业在21世纪世纪对通讯服务的需求，并计算出建设新资讯基础设施所需的投资成本。1.评估通讯服务潜在需求的方法：我们将资讯分为四个层次。0级（备忘录，短信），1级（演讲），2级（电视，图像，面对面交流），3级（储存信息的材料和书籍），并将它们与家庭支出联系起来。计算结果表明，2级和3级家庭对BISDN的需求大于（）SY。[)0 2. BISDN建设成本：选取了家庭对电话、视频观看的需求和企业对电话、传真、会议的需求，分析了需求、服务价格和BISDN建设投资成本之间的关系。我们的计算表明，如果BISDN的价格是今天电话费率的2 - 3倍，所需的投资费用为100万亿日元，这些费用在10年内还清，到2025年，我们将拥有50万亿日元的BISDN基础设施和100万亿日元的储蓄债券。3.医疗保健服务的成本降低：我们访问了电信对日本医疗保健的影响。计算结果表明，1990年新信息技术可节省20.6万亿日元的国家卫生保健费用中的1.5万亿日元。4.对300户家庭进行了调查，收集了BISDN需求-供给模型参数的信息。
