To make an international policies comparison of algorithmic ethical governance among representative regions, this paper constructs a symbiotic system model of algorithmic ethical governance, systematically comparing the differences in governance policies of the United States, the European Union, and China. The findings reveal that the EU emphasizes multi-stakeholder collaborative governance, the U.S. favors market-oriented self-regulation, while China adopts a government-led regulatory governance. Moreover, none of the three has yet achieved an integrated symbiotic governance model. Based on the comparative results, the study further identifies three key roles and responsibilities of the information resources management discipline in algorithmic ethical governance, providing a policy foundation for future governance design and academic engagement.
