在這幾十年當中，電子商務（EC）已成為最夯的研究領域。為了釐清EC的知識藍圖，並指出EC的研究熱點和未來的發展趨勢，本文以Scopus學術資料庫針對1990年至2017年的EC研究進行全面的文獻回顧。根據選取的11669篇EC文章，我們發現這些文章分別分散在1717種不同期刊，而其最初的研究始於1992年，在1997年起才有顯著地增加，並在2000年達到出版的高峰。美國是EC出版與被引用最多的國家。此外，美國，英國和加拿大是EC學術合作聯盟中排名前三的國家。根據11669篇文章所獲得的18315個關鍵字，我們歸納7個EC不同研究主題。本研究的貢獻在提供一種方法能將EC的研究範圍予以概念化與操作化，並發展一個概念性架構來組織EC的大量研究。最後本研究有一些討論和結論。

During these decades, e-commerce (EC) becomes an exciting and hot research area. To figure out the knowledge mapping of EC and to indicate its research hot spots and trends for future research, this paper made a comprehensive literature review on EC from 1990 to 2017 based on Scopus academic database. Based on the scope of 11669 EC articles, we found that these articles scattered across 1717 different journals while the research output began in 1992, significantly increased since 1997 and was at the peak of publications in 2000. The United States is the country with the most publication and the most citations. Besides, United States, United Kingdom and Canada are the top 3 collaboration cores in EC alliance. According to 18315 keywords from 11669 articles, we explored 7 clusters which represented different research subjects in EC. The contribution of our study is to provide a means to conceptualize and operationalize the coverage of EC. It provides a conceptual framework to organize this vast body of research. This study ends with some discussions and conclusions.
