The invention discloses a correlated color temperature and color rendering index analysis method of a light source. Different types of light sources in which correlated color temperature and color rendering index are known and the range covers the types, correlated color temperatures and color rendering indexes of a light source to be measured serve as reference light sources; irradiance spectra of the reference light sources are measured, standard format processing is carried out on spectral data, and a spectral matrix of the reference light sources is obtained; a gradual multivariate linear regression analysis model is established between the spectral matrix of the reference light sources and corresponding correlated color temperatures and color rendering indexes; an irradiance spectrum of the light source to be measured is measured, standard format processing is carried out on spectral data, and a spectral matrix of the light source to be measured is obtained; and an analysis-model dependent variable corre
