網 際網路成為資訊蒐集與傳遞的首要管道已無庸置疑,但由於目前之使用尚屬低費率,使得網際網路在使用上呈現正負雙重外部性的特性。一方面因網路規模之擴大提 高資訊容量,一方面卻也造成無用資訊過多與壅塞問題而使交易成本愈高,因此,使用者如何能既快又準的搜尋到所需之特定資訊,滿足自身對資訊時效性及完整性 之需求,便成為其對網路專業資訊服務有所需要的原因,亦形成此類服務之提供興起的主因。理論上,本研究設立一以網路使用者選擇經由專業資訊服務以取得一筆 特定資訊之願付價格,並證明,此願付價格可突破網路資訊之公共財特性而為一正數,表示當網際網路愈成為眾所依賴之資訊傳取管道時,專業資訊服務之興起與發 展即為必然的趨勢。其次,本研究進一步利用網際網路實施之問卷調查,結果顯示,目前個別使用者利用付費專業資訊服務以取得特定資訊的意願尚不高,但對於願 意付費以避免塞車與爭取時效者則有比例增加之趨勢。將問卷結果對應理論基礎,此使用者對費率的偏好傾向可引伸為其使用網路專業資訊服務之願付價格,並為未 來網路使用之效率價格機制設計的基礎。

The Internet becomes the most important media for people to receive and transmit information without any doubt. Currently, because of free charge or low usage fee, the Internet presents its nature of both positive and negative network externalities in consumption, which can be interpreted as the increasing capacity of information when the size of network is enlarged, and the larger network size induces the problems of junk mail and congestion incurring higher transaction cost at the same time. Therefore, the main reason for specialized information services sprouting and provided is that, the individual user has the desire to minimize the transaction cost of search and demand for the completeness and timing of a specific information through the Internet. Theoretically, this study set up an Internet user\'s willingness to pay for achieving a specific information provided by the specialized information service. This willingness to pay can be proved as a sufficiently positive value to break through the limitation of the nature of public goods of Internet information. This implies that when the Internet becomes more popular for information transmission and reception, the development of specialized information services will be the indispensable trend. In addition, this study employs a survey to the users through the Internet. The result of data analysis from the survey shows that the willingness to pay of the individual user to achieve a specific information through specialized information services is still low currently. But the willingness to pay is likely to increase for the individual user in order to avoid the congestion and to compete for the information timing. Thus, examining the theoretical inference with the empirical evidence, the user\'s preference to pay can be extended to the willingness to pay for using specialized information services, which also offers the designing consideration for an efficient pricing mechanism of the Internet usage in the future.
