This paper analyzes the effective Hamiltonian obtained by using a new first-principles calculation method that quantitatively describes the electronic state of copper oxide high-temperature superconductors proposed in arXiv: 1901.00763. The phase diagram of a copper oxide high-temperature superconductor of Hg system was quantitatively reproduced, and the mechanism of the high temperature superconductivity was analyzed.
