Research Note—Information Technology, Customer Satisfaction, and Profit: Theory and Evidence
研究了109家美国公司在1994-1996和1999-2006两个时期的数据，发现信息技术投资对客户满意度有正向影响，但对利润的影响在不同时期有正有负。
This paper studies the effect of aggregate information technology (IT) investments on customer satisfaction and profits at the firm level. Using data on 109 U.S. firms for the 1994–1996 and 1999–2006 periods, we find that aggregate IT investments have a positive association with customer satisfaction. However, the strength of the relationship varied across the 1994–1996 and 1999–2006 periods. Specifically, IT investments had a more positive influence on customer satisfaction for the 1994–1996 period than for the 1999–2006 period. Conversely, IT investments had a positive effect on profits in the 1999–2006 period, but a negative effect in the 1994–1996 period. These findings extend prior discourse in the information systems literature on the role of customer satisfaction as a mechanism that explains how IT-enabled benefits are “passed on to consumers” [Rai A, Patnayakuni R, Patnayakuni N (1997) Technology investment and business performance. Comm. ACM 40(7):90]. Our additional exploratory analyses showing that IT investments had a stronger effect on perceived quality than on perceived value provide an explanation for some of the observed effects of IT on customer satisfaction and profits. Together, these contributions and implications provide new insights to assess returns on IT investments by focusing on customer satisfaction, an important intangible and leading measure of firm performance, stock returns, and stock risk.
