Dynamic job-housing balance state evaluation method and system under planning scene

The invention discloses a dynamic job-housing balance state evaluation method and system under a planning scene, and relates to the technical field of urban planning. A'bridge 'of planning land and commuting amount is established to carry out dynamic job-housing balance evaluation in a planning scene, the relation between planning scene variables and dynamic job-housing balance key variables is broken through, dynamic job-housing balance evaluation in a planning state becomes possible, and quantitative support and evaluation means are provided for planning measures of job-housing balance; meanwhile, according to the scheme, a graph neural network algorithm based on a spatial domain is also constructed to carry out commuting flow distribution, the topological proximity effect between the land parcels is taken into consideration, the influence of local structures and neighbor attributes on the commuting flow between the land parcels is depicted, and the prediction accuracy, operability, algorithm efficiency and
