1. Info-Communications Infrastructure Growing in Sophistication and DiversityThe info-communications infrastructure in Japan is growing in sophistication and diversity in recent years. In the arena of wired networks, digitalization of NTTs exchange systems was completed in 1997, and subscriber network circuits are being replaced by fiber-optic lines in expanding scale. ISDN service subscription is also increasing with the rising popularity of the Internet. In mobile communication networks, cellular telephone use is growing rapidly, and plans are under way toward increasing data transmission capacity. Broadcast networks have also seen the introduction of digital broadcasting via satellite and CATV. Preparations are also under way to pave the way to digitalization of ground wave broadcasting.2. Government Action on Development of Info-Communications InfrastructureThe driving force in development of info-communications infrastructure is the private business sector. The principal role of the government in development is to secure a competitive environment. For this reason, it has taken such measures as NTTs restructuring, establishing rules on interconnectivity, and deregulation. At the same time, low-interest loans are being made available for fiber-optic network development, and support given for development of info-communications infrastructure in areas where operation is unprofitable. Furthermore, the concept of universal service in telecommunications that had earlier focused only on the telephone will also be reviewed regarding its ideal state in the future.3. Info-Communications and the EconomyThe steady growth every year in capital investment by the info-communications industry is keeping the Japanese economy afloat. In terms of contribution to GDP, info-communications investment compares viably with that in the United States. In addition, the multiplier effect it produces is estimated to be larger in impact than conventional public investment. Both on the demand side and supply side, info-communications is believed to contribute immensely to greater productivity. With the ongoing changes in the employment structure, etc. in Japan, the effect of this productivity increase is expected to be felt in the future.Furthermore, the Internet and other info-communications media are expected to play a major role in expanding business opportunities for small businesses in regional economies. To realize such opportunities, it may, for example, become necessary to set up a suitable advisory system offering counseling on use of such media.
