Information Technology and Sustained Competitive Advantage: A Resource-Based Analysis
作者用资源基础理论分析信息技术能否带来持续竞争优势。传统文献强调IT是竞争利器，但很少解释这种优势能否持久。作者基于资源基础观构建模型，考察IT的四类属性，资本需求、专有技术、技术性IT技能和管理性IT技能，是否可能成为持续竞争优势的来源。分析结论是，只有管理性IT技能能够提供持续性，其他三类因易被模仿或替代而难以持久。研究为理解IT战略价值提供了理论框架，强调组织能力而非技术本身才是长期优势的关键。
The concept of IT as a powerful competitive weapon has been strongly emphasized in the literature, yet the sustainability of the competitive advantage provided by IT applications is not well-explained. This work discusses the resource-based theory as a means of analyzing sustainability and develops a model founded on this resource-based view of the firm. This model is then applied to four attributes of IT-capital requirements, proprietary technology, technical IT skills, and managerial IT skills— which might be sources of sustained competitive advantage. From this resource-based analysis, we conclude that managerial IT skills is the only one of these attributes that can provide sustainability.
