數位落差在現今社會中已是非常普遍的一項名詞，它意謂著不同群體間取得資訊設備的差距，因而造成資訊來源取得能力的落差，而其中資訊設備從早期的電話、電腦，到現今的網路、寬頻，以致到未來更高階的數位通信技術皆可包括在內。
本文的目的在研究台灣家用網路及高速網路方面的數位落差，並根據實證分析探討其形成原因，進而思索相關對策，以期能縮短這方面的數位落差。

Digital Divide in the nowadays society already are an extremely universal noun. It signified the disparity between the different communities to obtain the information equipment, thus created the variance of the ability to obtain information origin. From early telephone, computer, nowadays network and broadband to the future higher order Digital Communication Technology all might include among the information equipment.

This article is studying the Digital Divide of Residential Internet Access and of the High-Speed Internet Access in Taiwan, and discusses its causing reason according to empirical analysis. Then think the correlation countermeasure to reduce the Digital Divide.
