联盟组合为焦点企业及合作伙伴的发展创造了丰富的成长路径,提高了企业的竞争优势。现有研究对联盟构型网络的结构、资源冗余性、路径联系与"网络效应"之间的关系,缺乏系统性、动态性的分析。本文围绕焦点企业,结合社会网络及纵向案例研究方法以大唐移动TD-LTE联盟组合为研究对象;探讨了联盟组合构型网络形成的动因、演化特征和路径;提炼了联盟组合构型网络动态演化框架。研究表明:联盟组合内的资源异质性与构型网络多样化密切相关。随着构型网络的规模扩大、路径依赖的增加,会导致整体网络效率的下降,收益递减。而不同阶段焦点企业的控制治理策略选择、网络的拓展与重构能有效提高联盟组合"网络效应"。  相似文献   

An empirical investigation of information sharing behavior on social commerce sites     

《International Journal of Information Management》2016,36(5):686-699

Social commerce sites (SCSs), a new model of social media, provide fertile ground for customers to communicate their opinions and exchange product- or service- related information. Given the significant opportunities related to the use of social media data for customers’ insight, we explore the factors driving information sharing behavior on SCSs. In this paper, we propose and empirically test a comprehensive theoretical model for customer information sharing behavior through analysis of online survey data as well as network and behavioral usage data of over four months from 1177 customers in a SCS. The research model was empirically validated with the use of both subjective and objective data in a longitudinal setting. Our results show that customer information sharing is influenced by both individual (i.e., reputation and the enjoyment of helping others) and social capital (i.e., out-degrees’ post, in-degrees’ feedback, customer expertise and reciprocity) factors. This study contributes to the existing literature by highlighting the role of directed social network in customer information sharing behavior on SCSs. We believe that the results of our study offer important insights to the IS research and practice.  相似文献

E-Commerce to Protect the Network Relationships: The Case of Taiwan's PC Industry     

Tain-Jy Chen 《The Information Society》2003,19(1):59-67

Although Taiwan is one of the world's leading producers of information products, it lags behind advanced countries in the application of information technologies. The strength of Taiwan's industry lies in its low-cost manufacturing capabilities, which in recent years have been undermined by rising wages. Faced with a massive relocation of production activities to China, the Taiwanese government is trying to prevent the hollowing out of domestic industry by encouraging local firms to embrace new information technologies to strengthen their ties to multinational firms. The initiative aims at enhancing the flexibility of production and speeding up responses to the market through concerted actions by brand marketers, parts suppliers, and assemblers. New technologies underscore new working methods that erect entry barriers to protect existing network relationships.  相似文献

Researching Internet Communities: Proposed Ethical Guidelines for the Reporting of Results   总被引：4，自引：0，他引：4  

Storm A. King 《The Information Society》1996,12(2):119-128

Communication researchers and social scientists are quickly discovering the value of data that exists in the postings of members of Internet e-mail, Usenet, and real-time groups. The ability to communicate with one's peers, no matter how esoteric the interests, is causing an explosion in the number of new virtual communities. The interpersonal dynamics of these groups are increasingly coming under the scrutiny of academic research. The publicly available archived records of Internet virtual communities are being analyzed for a wide variety of research interests. The ability to do naturalistic observations of group dynamics, as they are exhibited in these exchanges of text, has captured the attention of many researchers. The institutional review boards of major universities are granting researchers exempt or expedited (exempt from full review) status for this work, due to the public nature of the notes being analyzed. These studies often involve the lack of informed consent, where the group members under study are unaware they are being monitored. There is a potential for psychological harm to the members of these groups, depending on the way results are reported. This article explores the ethical considerations that must be taken into account to protect cyberspace participants. The guidelines proposed are based on the American Psychological Association ethical guidelines for use of human subjects in research. An explanation is offered as to how such guidelines can best be applied to the study of Internet communities. The constructs of Group Accessibility (the public/private nature of the actual cyberspace occupied by a group) and Perceived Privacy (the level of privacy that group members assume they have) are defined and proposed as two dimensions by which individual Internet communities may be evaluated in order to assure the ethical reporting of research findings.  相似文献
