| This study investigates the relationship between information technology investment and corporate productivity. Data Envelopment Analysis (DEA) was employed to classify corporations with regard to productivity, followed by a Discriminant Analysis procedure to determine if a relationship existed between the productivity classification and the information technology investment variables. A standard least squares regression model was also constructed for comparison with the DEA-discriminant results. The findings were that there is an association between the year and industry and productivity (which was expected); however, the productivity paradox could not be disconfirmed, i.e. a significant relationship between productivity and IT items was not evident. |
