Abstract: In a spectroscopic analysis system and a spectroscopic analysis method of the present invention, in determining a content percentage of a component contained in a measurement object based on a measurement object spectrum, one or more calibration curves for obtaining the content percentage of the component contained in the measurement object are selected out of a plurality of calibration curves generated based on reference spectra corresponding to a plurality of sections, into which a content percentage of each of a plurality of components is divided, and classified according to the sections using the measurement object spectrum and the reference spectra.
