IT投资与公司绩效研究

Information technology investments have been the central issues of IS research for over a decade. Despite large significant work has been done in IT payoff literature, a large number of research results of the IT-firm performance is mixed and complex. This study examines the influence of IT investments on firm performance by using listed firms in China from 2006 to 2008. The empirical results show a significant negative relationship between IT investments and current period ROA. This study also reveals that IT investments have a significant negative influence on current period ROS. However, current period Tobin Q doesn't have any significant relationship with IT investments. What's more, we don't find any significant relationship between Information technology investments and the next year Tobin Q, ROA, ROS after current period , either. This study reveals IT investments tend not to impact on recent corporate performance actively. This suggests that Information technology investments don't contribute to recent firm performance in China, and 'productivity paradox of Information technology' does exist in China. The findings enrich and develop IT performance literature in China.
