Firms that are traditionally not in the scope of IT increasingly develop IT services as new business lines to create better customer offering portfolios. The current research takes the first step to theoretically explore and empirically examine how these firms’ diversification to IT services may affect their performance as reflected in firm value. Furthermore, these relationships are modeled into three key interactions with firm size, firm age, and firm service intensity, to decode the differential roles of this diversification strategy on firm shareholder welfare in the varying scenarios along with the moderators. This research generates implications for theories such as IT and knowledge management, resource-based theories, and it provides practical implications for business managers.

传统上不属于IT范围的公司越来越多地将IT服务开发为新的业务线，以创建更好的客户服务组合。当前的研究迈出了第一步，从理论上探索和经验检验了这些公司向IT服务的多元化如何影响其在公司价值中所体现的绩效。此外，将这些关系建模为与公司规模，公司年龄和公司服务强度有关的三个主要交互关系，以在不同的情况下与主持人一起解读这种多元化策略对公司股东福利的不同作用。这项研究对诸如IT和知识管理，基于资源的理论等理论产生了启示，并为业务经理提供了实际的启示。
