Purpose: The purpose of this paper is to propose and validate a public value-based framework for evaluating the performance of electronic government (e-government), leading to the identification of the critical factors in creating public value through e-government in developing countries. Design/methodology/approach: A comprehensive review of the related literatures is conducted for developing a public value-based framework. A survey of e-government users is conducted, and the survey data are analysed using structural equation modelling. Findings: This study shows that information quality, e-services functionalities, user orientation, efficiency and openness of public organisations, equity, citizens' self-development, trust, and environmental sustainability are the critical public values of e-government in developing countries. It reveals that the use of the public value concept is effective in evaluating the performance of e-government in developing countries. Practical implications: This study provides a comprehensive investigation of the e-government performance for better understanding the value of e-government in developing countries. The findings can guide the development of e-government in developing countries. Originality/value: This is the first study in testing and validating a public value-based framework for evaluating the performance of e-government in developing countries. It demonstrates how the concept of public value can be adopted for evaluating the performance of e-government.
