It is our pleasure to present the special issue of Journal of Electronic Commerce in Organizations. In this issue (Volume 11, Issue 2), we selected six papers which have gone through several rounds of review and revision, and represent a cross-section of research in the e-Commerce area that touches upon technical and managerial issues. In the first paper titled " A New User Segmentation Model for E-government " , the authors introduce CRM and customer segmenta-tion concept into e-government areas, construct e-government user segmentation model and empirically test the user segmentation results. The second paper examines the structure and evolution mechanism of B2B e-commerce network. The authors modified a Barabasi-Albert model by incorporating more layers and parameters and revealed that the emergence of scale-free nature depends on the growth mechanism. The third paper presents a framework for security mechanism of Internet of Things (IoT) based on RFID, which includes authentication and access control, data encryption and legislative protection. In this fourth paper, the authors specifically examined how e-Business application affects business performance in a Chinese context by using VAR model. Results show that e-Business is most critical to business success especially for small companies in China.

The last paper examines e-Commerce issues from
