The moral system of artificial intelligence is dynamic and constantly updated. It is an important
research direction to build a moral model based on the common moral concerns of the society. This
paper aims to explore the public’s moral concern model for artificial intelligence. Using grounded theory
to analyze 17 interview data, 23 categories and 8 main categories were formed. From the structural
relationship of the main categories, it can be concluded that the public’s moral concern model for artificial
intelligence consists of two layers, namely the causal layer and the influence layer. The causal layer is
composed of moral cognition and controversial points, the controversial point is the root cause, and the
moral cognition is the direct cause; the influence layer is composed of moral norms and controversial
points, and affects moral concerns through mediation and adjustment. Research offers concrete paths to
reduce public concerns about the ethics of AI.
