An automotive body joining position optimization analysis method according to the present invention includes: setting all or a part of an automotive body model as an analysis object model (S1); generating an optimization analysis model 151 by setting a candidate for weld line to the analysis object model (S3); setting a variable amplitude load condition (S5); setting the reciprocal of a predetermined target fatigue life as a target liner cumulative damage (S7); setting improvement of the stiffness of the optimization analysis model 151, a reduction in the liner cumulative damage, which is the reciprocal of a fatigue life of the candidate 155 for weld line, and minimization of the length of the candidate 155 for weld line as optimization analysis conditions (S9); performing optimization analysis by giving the variable amplitude load condition to the optimization analysis model 151, and determining the optimal arrangement of the weld line 157, which achieves the optimization analysis condition (S11).
