　　信息技术投资能否对企业绩效产生影响一直是信息系统研究者和实践者关心的一个热点问题。选取2009年中国上市企业500强作为样本，研究了制度、社会网络对信息技术投资与企业绩效之间关系的影响。研究发现，信息技术软件投资能够提高企业绩效；制度能够正向调节信息技术硬件投资和信息技术总投资与企业绩效之间的关系；对于沿海地区的企业，社会网络能够进一步调节制度对信息技术硬件投资和信息技术总投资与企业绩效之间关系的影响。扩展了信息技术投资与企业绩效之间关系的研究框架。

Whether investments in information technology (IT) have an impact on firm performance has been and continues to be a major problem for information systems researchers and practitioners. This study discusses and empirically tests the effects of institutions and social networks on the impact of IT investment on firm perfor-mance with the sample consisting of top 500 listed China corporations in 2009. Results indicate that IT software investment could improve firm performance, and the development of institutions positively moderates the relation-ship between IT hardware investment or IT total investment and firm performance, and inter-organizational net-work further positively moderates the effect of institutions on the relationship between IT hardware investment or IT total investment and firm performance for firms located in coastal area. The study extends the framework that shows the relationship between IT investment and firm performance.
