【Abstract】 In this paper,we study the impact and lag effect of IT investments on firm profitability,from two determining dimensions,i.e.,revenue and expenses.By examining data of Chinese public companies,we find that IT investments have significant and sustaining effect on firm revenue growth.However,IT investments also lead to an increase in operating expenses.With regard to firm profitability,the contribution of IT is increasing over years,and becomes significant from the third year after investment.Furthermore,we find that IT investments have much stronger effects on firm performance than non-IT investments.Compared with manufacturing sectors,firms in non-manufacturing sectors have much better IT performance in terms of the sustaining significant growth in both sales revenue and profits.更多还原
