A plasma processing apparatus, plasma processing method, and plasma processing analysis method in which a suitable combination of wavelength, time interval, and etching condition parameter for control to change etching conditions is determined among wavelengths, time intervals, and changeable parameters for spectroscopic measurement data in order to ensure stable etching conditions. Specifically, a regression equation which represents the correlation between emission intensity and etching result at a wavelength and a time interval is obtained for each of two or more combinations of wavelength, time interval, and etching condition parameter. Furthermore, for each of the combinations, the amount of change is calculated from the regression equation when the value set for the etching condition parameter is changed. Among the combinations, the combination for which the amount of change is the smallest is determined as the combination of wavelength, time interval, and changed etching condition parameter to be used for control.
