Based on an intent mapping mechanism, the matching degree between behavior and space is determined. Combined with counterfactual simulation and causal analysis, spatial mismatch and its causes are located. This invention can automatically identify service blind spots and output space optimization suggestions for different groups, improving the refinement and fairness of community public space governance.
