By theoretically analyzing the core-level spectra, such as X-ray photo-emission (XPS) and X-ray absorption (XAS), with the use of the impurity Anderson model, we discuss the electronic structure of high Tc superconductors and some related materials. From Cu 2p-XPS we obtain the information on the charge transfer energy from 0 2p to Cu 3d states and on the hybridization strength between these states. The polarization dependence of Cu 2p-XAS and 0 1s-XAS provides us with the most direct information on the site and the symmetry of doped holes. An analysis of X-ray emission spectra is also made using the same model system.
