The invention discloses a method and a device for constructing a spectral quantitative analysis model. The method comprises the following steps: acquiring a chemical value and a spectral feature of a training sample; obtaining a regularization parameter initial value and an insensitive loss function parameter initial value through calculation according to the chemical values and the spectral characteristics; obtaining an optimal regularization parameter and an optimal insensitive loss function parameter through parameter optimization; and constructing a spectrum quantitative analysis model according to the optimal regularization parameter and the optimal insensitive loss function parameter. According to the embodiment of the invention, the regularization parameter initial value and the insensitive loss function parameter initial value are calculated through the chemical value and the spectral characteristic of the training sample, and the parameter optimization and the construction of the spectral quantitativ
