Using resource-based view(RBV) of the firm as a theoretical foundation, we aim at finding out the impact of the complementarities between business skills and technical skills of IT staff on the firm's competitive advantage. Based on literature review, a concept model mapping the linkage of the capabilities and its complementarities of IT staff to the enterprise performance is set up. Through the survey of 300 Chinese companies, the statistics implies that the IT staff's technical skills and business skills both have significant positive correlation with the enterprise performance and the two capabilities are significantly complementary to each other. The technical skills distinguish IT staff from other business counterparts, and the business skills help IT staff understand how to utilize the strategic potential of IT to support and shape businesses. The research results indicate that the synergy between the two kinds of skills would further improve enterprise performance.%以资源基础观为理论指导,研究IT人员的技术能力与业务能力以及二者的协同效应对企业竞争优势的影响.在已有研究成果的基础上,构建了企业IT人员能力及其互补性与企业经营绩效关联的概念模型,通过对国内300家大中型企业的问卷调查和统计检验,验证企业IT人员的技术能力和业务能力与企业绩效都有着显著的正相关关系,而且这2种能力之间也存在较强的互补性.研究结论显示,技术能力是IT部门人员区别于其他部门的根本,业务能力使IT人员能够更好地理解企业业务,进而充分发挥IT系统的战略作用,产生的协同效应能够进一步提升企业的经营绩效.
