Measuring Electronic Government Procurement Success and Testing for the Moderating Effect of Computer Self-efficacy

Based on a survey data from 361 public employees and suppliers in Taiwan, this study employed the updated DeLone and McLean Information Systems (IS) Success Model to measure e-government procurement (e-GP) system success and assess the moderating effect of computer self-efficacy on users’ judgment of IS success. Results showed that information quality, system quality, and service quality had a significant effect on individual performance through the usage and user satisfaction with an e-GP system. In addition, the key antecedents to user satisfaction and system usage did differ between high and low computer self-efficacy users. By measuring the success of an e-GP system from the end-user’s perspective, the findings of this research provide insight into the design and improvement in electronic government procurement.
