The invention discloses a dynamic financial strategy generation method based on cost behavior clustering, and particularly relates to the field of tax strategy management, and the method comprises the steps: obtaining a historical cost
record and a regional tax rule text, the historical cost
record comprising a cost type, an expenditure amount,
occurrence time, an affiliation subject and an affiliation region; and performing
field analysis operation on the region tax rule text according to the affiliated region in the historical cost
record, extracting the deduction application condition, the deduction calculation proportion, the
declaration voucher requirement and the accounting
processing program of each fee type in the corresponding region, and constructing a region tax rule set. A regional tax
processing model is introduced, a cost behavior clustering result is matched and mapped with tax rules of each region one by one, and a tax strategy generation mechanism with regional difference adaptability is constructed, so that the problem of strategy mismatching caused by the fact that the heterogeneity of the tax rules is not modeled in the prior art is solved.
