Increasing　information　can　make　actions　more　effective,　thereby　improving　cooperation　levels.　However,　this　assumption　lacks　experimental　support　in　the　case　of　long-range　migration,　and　the　potential　mechanism　for　higher　cooperation　rates　resulting　from　inter-group　migration　is　not　yet　clear.　Therefore,　we　mainly　studied　the　impact　of　four　different　information　levels　on　group　cooperation　behavior　from　an　experimental　perspective　through　public　goods　game　experiments　in　the　context　of　long-range　migration.　The　results　indicate　that　the　amount　of　information　can　significantly　affect　individual　mobility　and　cooperation　evolution.　Defection　prevails　among　players　in　the　absence　of　information,　leading　to　the　formation　of　a　stable　cluster　of　defectors.　However,　with　increased　information　about　profit　calculation　rules,　players　tend　to　settle　in　favorable　cooperative　groups.　Increased　information　about　the　decisions　of　other　players　speeds　up　the　formation　of　stable　cooperative　groups.　Excessive　information　disclosure　about　payoffs　leads　to　increased　mobility　and　reduced　cooperation　among　group　members.　These　findings　provide　insights　into　our　understanding　of　the　evolution　history　of　human　cooperation　and　the　formation　of　groups.　©　2023
