Researches on the comprehensive benefit of power-communication shared towers can effectively promote their rapid development and construction.Based on the actual data of typical projects of shared towers in a province from 2020 to 2022,the indicators of evaluation are objectively screened,the TOPSIS method is chosen for the com-prehensive benefit evaluation of shared towers,and the TOPSIS evaluation model suitable for the comprehensive benefit evaluation of construction projects of shared towers is established,which can evaluate different schemes of construction as well as providing decision-making reference for the development and construction of power-communi-cation shared towers.
