Abstract: The development and utilization of "urban minerals" is a complex process with multiple agents and multiple stages. This paper starts from five main agents and extracts thirty-five behavioral influence factors to construct a multi-agent collaborative evaluation index system for the development and utilization of urban minerals. To reflect the indicators' relevance, based on the multi-agent collaborative questionnaire, the ANP is used to calculate the indicator weights, which are then used as the input of the BPNN model. The collaborative evaluation model is constructed by analyzing the BPNN model's principle, and the training, testing, and verification of the BPNN are carried out with multiple sets of samples as the prior samples. It is found that social environment, environmental responsibility, transportation cost, recovery cost, and market environment are the key indicators that affect the multi-agent coordination of urban minerals, and there is heterogeneity in index weights of enterprises of different nature and sizes, which provides a certain decision-making reference for the development and utilization of urban minerals.
