Abstract Recently, The ¡uDigital Revolution¡vchanges the store of the knowledge. The traditional conveyance of knowledge, book, have been gradually replaced by store equipments that have immense storage. Then, the internet totally changes information of the exchange. For the reason, the new storage technology and the specialization of the internet make the application and management of information a new landmark. The provision and exchange of public information are the essential activities in a democratic regime. But local study mostly focus on the administration, little study on legislative Yuan. Hence, this paper is intended to investigate representative behavior of Taiwan¡¦s legislators. Legislators are the representative of constituency. They are not only responsible for constituency, but need to monitor administration, law-making. Exchange of information is of utmost significance. The appearance of internet has positive affect on representative behavior of legislators, this paper discuss all of topics. Finally, after the seventh phrase of constitutional reform, the number of seats that legislators have reduce to half in th legislature. In addition, the legislators suffer the pressure of a single-constituency, two ballot system. I believe that legislators¡¦ paying more attention to the access the internet helps improve the quality of the activating in constituencies. I expect that the results of this study may increase the legislature revolution.
