This　paper　aims　to　explore　the　impact　of　donors’　trust　in　project-related　information　on　the　dynamic　process　of　charitable　crowdfunding　propagation　in　social　networks.　Firstly,　a　theoretical　model　employing　the　discrete　Markov　chain　and　mean　field　theory　is　proposed　to　describe　the　underlying　dynamics　of　the　crowdfunding　propagation　mechanism,　utilizing　trust　to　reveal　the　corresponding　donation　behaviors　of　crowdfunding　audiences.　Then,　a　leveraging　simulation　experiment　is　conducted　to　validate　the　accuracy　of　the　proposed　model.　The　numerical　experiments’　results　indicate　that　improving　the　donors’　trust　in　project-related　information　has　a　more　significant　impact　on　crowdfunding　propagation　than　the　choice　of　the　social　network　platform　for　fund　raising.　Moreover,　achieving　success　is　more　feasible　through　accumulating　a　substantial　amount　of　social　capital　than　by　lengthening　the　duration　of　the　campaign.　Finally,　the　validity　of　the　model　is　verified　using　actual　datasets　from　the　Qingsongchou　web　platform,　with　relative　errors　for　two　projects　being　only　3%　and　7%,　respectively.　This　paper　provided　novel　insights　into　the　internal　mechanisms　and　the　dynamic　process　of　crowdfunding,　providing　initial　evidence　for　what　appears　to　be　a　crucial　and　fruitful　phenomenon　in　crowdfunding　research.　©　The　Author(s),　under　exclusive　licence　to　Springer　Nature　Switzerland　AG　2024.
