Using data from more than 300 firms in the United States, we find that at the mean value of IT investments, firms with a dual IT strategic emphasis have a higher market value as measured by Tobin’s Q than firms with a revenue or a cost emphasis, but they have similar levels of profitability. Of greater importance, IT strategic emphasis plays a significant role in moderating the relationship between IT investments and firm performance. Dual-emphasis firms have a stronger IT–Tobin’s Q relationship than revenue-emphasis firms. Dual-emphasis firms also have a stronger IT– profitability relationshi
