講座題目：Information technology and firm performance: A longitudinal event study approach incorporating resource-based view with capability building and dynamic capabilities theories

講座梗概：

Information technology paradox (IT paradox) problem has been studied by IS scholars for decades, with their efforts to explore the economic value of information technology for firms. Although the literature in this line has broadened our knowledge, the results are inconclusive and some research gaps have been identified. First, due to the mixed findings of prior studies, whether IT investments lead to better firm performance is still a problem. Second, IT investments are often considered in general by prior studies, leaving the effects of specific IT unknown. Third, while some scholars discussed the importance of time lag effect, to our best knowledge, it has not been empirically addressed.

In this study, we will adopt a long-term event study methodology with firms secondary financial report data to investigate the relationship between IT (e-channel) investments and firm performance. Based on resource-based theory, complemented with capability building perspective and dynamic capability theory, we propose a complete conceptual model to explain the IT paradox problem by taking time lag issue into consideration and argue that IT investment will first help firms build their IT-enabled capabilities, and then lead to firm performance. Specifically, firms complementary resources play an important role in forming capabilities (capability building perspective); and only those firms fitting capabilities with external changing environment can finally lead to firm performance (dynamic capability theory).

To test the model, I used 136 firms e-channel investment events and their longitudinal financial data. The results showed that IT investment lead to firm performance, through IT-enabled capabilities. Time lag indeed exists, four quarters specifically for e-channel investment. The time lag can be divided into two periods: first period is used to do capability building learning, while second period is to accomplish strategic learning. The results also suggest that organizational complementary resources are crucial for transferring IT resources to capabilities, while dynamic capabilities are important for leading IT-enabled-capabilities to firm performance.
