The advancement in internet and information technology has facilitated the evolution of the e-finance, which stands for the provision of financial services and markets using electronic communication. The Internet users in Greece have been multiplied in recent years. At the same time, the number of users who utilize the Internet banking, the Internet Stock Exchange Services and the e-insurance has been increased progressively. However, Greek people are not familiar with the knowledge of the technique and the possibilities of the internet auctions and the e-bond transactions.This was the reason we first tried in this thesis to locate the globally available e-bond networks and to examine their characteristics and the services they provide so that we can then draw conclusions on the domestic market. One of the points we make is that several existing e-bond networks provide bond transactions to institutional investors but others provide transactions to individual investors. Second, we investigated the two platforms which are available for bond transactions in Greece: the Electronic Secondary Securities Market and the Completed Automated Electronic Transaction System. We have to point out that the brokers act as agents to post investor orders and individual investors cannot participate immediately and without intermediates in these two platforms. All these findings forced us to examine how we could upgrade bond transactions in Greece. So, through this doctoral thesis, we decided to build a model platform that could be used for the handling of bond transactions in Greece. Both individual and institutional investors could contact transactions in this platform. The functioning and the characteristics of this platform were based on the comparison of characteristics and operations of several e-bond networks we examined globally.
