A system upgrade assessment method based on system parameter correlation coefficients is provided. The problem that the existing system upgrade assessment method cannot accurately assess an upgraded system is solved. For such a purpose, the system upgrade assessment method comprises the following steps: acquiring first data for a plurality of parameters before system upgrade (S); acquiring second data for the plurality of parameters after the system upgrade (S); calculating first correlation coefficients of the first data and second correlation coefficients of the second data (S); calculating third correlation coefficients between the first data and the corresponding second data (S); and determining, based on the magnitudes of the first correlation coefficients, the second correlation coefficients and the third correlation coefficients, whether the system upgrade succeeds (S). By comparing the correlation coefficients of the system parameters before and after the upgrade, the system upgrade assessment method can accurately determine whether the system upgrade succeeds.
