隨著網際網路的傳輸技術進步，以「數位出版」的模式提供服務成為圖書館發展的趨勢，進而帶動了數位閱讀的型態。本研究以台灣雲端書庫為重點，聚焦於「計次借閱」的服務型態，探討合作圖書館與台灣雲端書庫使用者對於新型態的電子書借閱機制，並針對遠流出版社以及高雄市立圖書館提供之原始數據，分析使用者借閱情況，觀察借閱現況上出現之問題並提出建議。 歸納本研究之結果發現： （1）經由網站的觀察及原始數據的分析中發現，各站台內容不同，高雄市立圖書館辦證情況之基本資料內容與本身資料庫數量有落差。借閱機制上並未達到完善的處理。 （2）藉由問卷瞭解數位閱讀主要潛在族群之範圍與閱讀行為，以及電子書服務滿意度。以年齡作為主要的區分條件，取得數位閱讀使用者概括性的行為模式，並發現使用者對於台灣雲端書庫網站實際操作效益都有正向的影響。 （3）根據訪談者表示：除了推廣活動的宣傳以外，各館經費來源不一，也是影響使用率的因素之一；另外購置台灣雲端書庫之圖書館在採購電子書時，主要考量因素為格式、連線速度、穩定性等，並考量廠商信譽與其提供之書種與本身買斷書種重複率；並提出熱門及暢銷書為電子書種類中最大需求的類型。因此受訪者大多認為「按次計價」的借閱模式能有效提供讀者適當的服務，並藉由公共出借權的意念促使作者釋放電子書版權。 最後，本研究提出提升電子書借閱服務持續使用意願的具體建議，以供圖書館加強電子書借閱服務使用意願之參考。 / The advance of the transmission technology of the Internet has the service pattern of “digital publishing” become the development trend of libraries and further drive the type of digital reading.
