PROBLEM TO BE SOLVED: To accurately evaluate a radio interference amount for a ground-satellite frequency sharing communication system, and to determine the maximum number of communication lines in the system. SOLUTION: The ground-satellite frequency sharing communication system 100 shares the same frequency between a ground line for performing radio communications, between: a ground terminal 51 and a base station 52; and a satellite line for performing radio communications between a satellite terminal 61 and a satellite 62. For the ground-satellite frequency sharing communication system 100, an interference evaluation method has: a radio interference computation step for computing radio interference in one radio communication on the ground line or on the satellite line, based on at least one or more other radio communications on the ground line and/or on the satellite line; and a number-of-communication-lines calculation step for calculating the maximum number of communication lines that can be accommodated in the ground-satellite frequency sharing communication system 100, based on a computation result of the radio interference computed in the computation step.
