Abstract—The purpose of this study was to determine trends and transformations in the electronic commerce (EC) research after dot com crash of 2000. This paper reviewed 779 articles published from the nine journals that are appropriate outlets for EC research  during calendar years 2000 to 2006 and comparatively analyzed with the previous research . The principal aspects of EC research are identified in four categories: application areas, technological issues, support and implementation, and others. Moreover, a unified model of electronic commerce was presented to explain the relations among the major three categories. We believe our findings to be valuable to the field of EC research with providing a source for anyone interested in EC research and helping simulate further interest. Keywords-electronic commerce; classification; comparative analysis; literature review I.INTRODUCTION
After a decade’s development, the researches of electronic commerce (EC) have achieved considerable accomplishments as shown in Fig. 1. EC related papers issued in nine international journals have realized 183% rise from the 275 articles between 1993 and 1999  to 779 ones between 2000 and 2006. Whereas EC seems to rise and fall with the dot com boom and crash around the turn of the millennium, academic research has been less cyclical. The steady growth in EC literature more accurately tracks the actual evolution of the electronic commerce . Figure 1. Distribution of articles by year.
Given the sheer volume of electronic commerce research publications, it seemed obvious that a surveying of the literature and an interpretation of this literature was in order. To this aim, we were especially interested in the evolution of the discourse for 7 years after the dot com market crash. Meanwhile, the selection of nine journals over a 7-year period is in keeping with previous scientometic study of Ngai & Wat . Moreover, it is our goal that this kind of study through comparing our survey result with Ngai & Wat  will enable us to identify research trends, transformations, gaps or weaknesses that will guide future investigation into this important area. II.RESEARCH METHODOLOGY
The journal basket as the publishing outlets for EC research in this study  chosen included: Communications of the ACM, Decision Support Systems, Computer (IEEE), IEEE Internet Computing, Information and Management, Information Management and Computer Security, International Journal of Electronic Commerce, Internet Research, and Journal of Organizational Computing and Electronic Commerce. The descriptors used in the literature search are same as Ngai & Wat , including “Electronic Data Interchange (EDI)”, “Electronic Commerce (E-Commerce)”, “Electronic Business (E-Business)” and “Internet Commerce”. More than 1050 articles were found in the initial search of the literature. The full text of each article was read to identify whether this article that was actually related to EC. 278 articles were excluded because they did not meet the selection criteria, described as follows: Conference proceeding papers, master’s theses, doctoral dissertation, textbooks, and unpublished working papers were excluded, as academics and practitioners alike most often use journals to obtain information and disseminate their research finding. Hence, journals represent the highest level of research, both in width and breadth. The criteria for exclusion further were applied to the articles in journals if they were editorials, news reports, and book reviews. Finally, we have picked 779 articles relevant to the subjects that the EC research for the term 2000-2006 from the nine journals. III.RESEARCH TAXONOMY
