自一九八Ｏ年代起，現代資訊與通訊科技(Information and Communication Technology or ICT)、電腦中介傳播(Computer-Mediated Communication or CMC)、網際網路(Internet)及全球資訊網(World Wide Web or WWW)的發展和普及化，已被學者、政治人物、以及論者們認為是可用以加強實踐公民參與及民主政治之有效工具。本研究即探討政府如何透過網際網路來提供公民參與機制。 本研究以網際網路之公民參與機制的理論為基礎，建構一個完整的網際網路之公民參與機制，亦即建構一個理想的網路公共論壇版面。並檢視台北市政府於全球資訊網網站上之公共論壇版面的運作現況及其成效，檢驗其中公民參與公共事務價值的實踐程度。最後，將探討網際網路之公民參與機制的實踐會有哪些侷限，應如何加以突破，藉此提供學術界及實務界研究貢獻。 / Since the 1980's, many scholars, statesmen, and researchers have come to realize that the development and popularity of modern Information and Communication Technology (ICT), Computer-mediated Communication (CMC), Internet, and the World Wide Web (WWW) will become the effective mechanism for citizen participation. The main purpose of this research paper is to study how government provides citizen participation through Internet. First, the paper will take the theory of Internet citizen participation to construct an ideal mechanism of Internet citizen participation, i.e., to build an ideal operational procedural of Internet Public Forum. Second, the paper will use Taipei City Government's "Citizen Forum" in the World Wide Web as a case study to compare and analyze this case with the ideal operational procedural of Internet Public Forum. Last, the paper will discuss the constraints of Internet citizen participation, and search for solutions to these constraints.
