The invention discloses a screening and weight determination method and system for electricity selling market profit capacity evaluation indexes. At present, some methods for improving index correlation used for classifying and screening a plurality of evaluation indexes and adjusting the indexes through weights can only reduce the correlation between the indexes to a certain extent, and the correlation cannot be thoroughly eliminated. According to the method, the correlation between indexes is removed by adopting a Schmidt orthogonalization method, and then the index sample data is normalizedthrough an off-differential standardized method, and the relative importance degree comparison value matrix among all indexes is determined on the basis of the normalized index sample data, and finally, the weight of each index is solved by adopting a hierarchical analysis method. The influence degree of all indexes on the market profit level can be better reflected through the weight result, andan important profit index
