 note = {日本の移動体通信市場は、ここ数年急激な変化を見せている。携帯電話市場の競争は、料金競争からデータ通信や音声品質の差別化を含むサービス競争に移行しつつある。また携帯電話料金の低廉化はポケベルの成長の余地を奪い、同市場の縮小を招いている。PHSも携帯電話市場にシェアを奪われたが、都市部でのデータ通信サービスで生き残りを図っている。これらのサービスも数年後にはIMT2000のサービス開始によって大きな影響を受けるものと予想されている。このような携帯電話の普及は、既存の加入電話との代替による要素が極めて大きいと考えられる。しかし、上記のような携帯電話と加入電話との代替が普遍的なものであるかどうかは疑わしい。例えば、米国の場合には、日本よりも低廉な加入電話料金が携帯電話の普及を抑えている可能性がある。本研究では、日本と米国の携帯電話市場の比較によって、携帯電話と加入電話の代替性の有無を定量的に分析することを目的とする。特に、料金水準と料金制度の相違が両国の市場にどのような違いをもたらしたのかを検証する。, The mobile communication market in Japan has seen a rapid change for these several years. The cellular telephone market kept growing up rapidly since sales of the handsets and pricing were deregulated. The number of cellular telephone subscribers has reached 56 million at the end of March 2000. The competition in the cellular telephone market is shifting from the stage of price competition to that of service competition, which includes the differentiation on the data transmission and the voice quality. Moreover, the price reduction of the cellular telephone service has deprived of the paging service the room for growth. Also the PHS (Personal Handy Phone System) was deprived of its share by the cellular telephone, but still survives as the data transmission service in the metropolitan area. It can be expected that these services will be greatly influenced by the IMT2000, which started in 2001. In Japan, it is said that one of the main causes, which brought the explosive diffusion of the cellular telephone, is substitution effect over POTS (plain old telephone service). However, it is doubtful whether the substitution between the cellular telephone and POTS can be seen universally in every country. In the United States, for instance, there is a suspicion that the price of POTS,which is cheaper than in Japan, suppresses the diffusion of the cellular telephone. That is, POTS is relatively expensive in Japan, because of the initial installation charge. On the other hand, cellular telephone users do not welcome incoming calls in the united States, because of the existence of the charge to incoming calls. Such a situation also influences the growth of paging service market. In Japan, even students tend to use the cellular telephone instead of the pager, and therefore the number of paging service subscribers keeps decreasing as mentioned above. 0n the other hand, the share of the paging service is still large in the United States. In this paper, we aim to analyze substitution effect between the cellular telephone, ISDN and POTS in Japan empirically. Especially, we investigate the characteristics of the substitution from the fixed access to the wireless, in order to foresee the future of the local competition in Japan., 4, KJ00000697071, 論文, Article},
