During the past few years, cyberspace and electronic commerce has been expanding throughout the world rapidly. The purpose of this paper is to find out policy leverages for boosting up cyberspace and electronic commerce using system dynamics simulation modeling approach. The system dynamics simulation model developed in this paper allows analysis of both the effect of factors on dynamic growth pattern of cyberspace as well as the effect of time delay in information processing, money transfer and delivery on model behavior. Finding of this study is that capacity of information infrastructure and size of cyberspace population are key factors of cyberspace growth. Also, reducing time delay in information flow, money flow, and delivery flow is an important policy leverages for growth of electronic commerce.

인터넷은 컴퓨터와 네트워크의 가상공간을 통하여 그 개방성과 뛰어난 확장성으로 전자상거래의 기본수단이 되고 있으며 경이로운 발전을 거듭하고 있다. 이에 따라 현재 전세계는 전자상거래가 폭발적으로 성장하는 시기를 맞이하고 있다. 일본에서도 최근 일본정부가 2005년까지 초고속인터넷을 3000만 가구에 보급할 계획을 세우고 있는 등 인터넷의 고속화가 빠르게 진전되고 있고, 이용자의 인터넷 접속요금도 저가격화로 변화함에 따라 전자상거래 이용지도 급속도로 증가할 것으로 예상된다. 그리고 TV를 이용한 게임기나 인터넷 전용머신이라는 컴퓨터 이외의 디지털기기로 인터넷을 이용하는 등 전자상거래 이용수단도 다양화될 것이며, 또한 디지털 텔레비전과의 제휴를 통하여 디지털데이터방송을 활용한 전자상거래도 활발히 이루어질 전망이다. 이에 따라 일본의 전자상거래시장의 급속한 성장과 함께 결제수단도 다양화되고 있다. 전자상거래의 결제수단으로서는 현금, 우편환, 은행입금, 수표 외 전자상거래의 특유의 결제수단이라고 할 수 있는 전자화폐, 인터넷뱅킹, E-Debit 등이 있다. 이 가운데 전자화폐는 일반적으로 유통성, 양도가능성, 범용성, 익명성 등 현금이 가지고 있는 기능을 갖추고 있을 뿐만 아니라 원격지송금성, 수송상의 비용절감, 금액의 분할 및 통합의 유연성, 전자성 등의 특징을 갖고 있으며 현금의 단점을 보완하는 기능도 있기 때문에, 앞으로 신용카드를 대체하는 차세대 전자결제수단으로 등장할 것이 확실시된다. 따라서 본고에서는 현재 일본 내의 다양한 주체들에 의하여 개발 실험되고 있는 전자화폐에 의한 결제시스템을 개관함으로써 우리나라에서도 일본과 같은 다양한 전자화폐에 의한 결제시스템의 개발 실험 도입이 절실함을 제안하였다.
