Assessing　the　promotion　of　economic　growth　between　China　and　the　world　is　challenging　given　data　limitations　and　the　lack　of　consideration　of　time　delay.　Based　on　the　time-series　nighttime　light　(NTL)　data　from　satellites　covering　more　than　100　months,　we　found　that　the　world　is　lighting　in　most　countries,　even　after　a　sudden　jump　due　to　the　outbreak　of　COVID-19.　Then,　we　conducted　the　convergent　cross-mapping　before　COVID-19　(2014.1-2019.12)　and　during/after　COVID-19　(2020.1-2022.11),　we　found　that　the　influences　from　China　to　the　world　economic　growth　in　these　two　phases　are　widely　expanded　to　more　and　more　economies,　the　number　of　which　increases　from　65　to　73,　with　a　longer　time　lag,　which　averagely　increased　from　4.6　to　6.6　months.　On　the　contrary,　the　number　of　economies,　which　can　influence　China’s　economy,　is　increasing　from　48　to　55　but　the　average　lag　time　is　stable　at　around　4.5　months.　Meanwhile,　a　regional　multilateral　economic　network　related　to　China’s　economy　was　found.　The　economies　with　mutual　causalities　with　China　were　mostly　concentrated　in　Asia,　Africa,　and　Europe.　China　indeed　can　warm　the　world　economy　partially,　especially　in　developing　countries　and　has　also　benefited　from　the　multilateral　economy.　©　2024　The　Author(s).　Published　by　Informa　UK　Limited,　trading　as　Taylor　&　Francis　Group.
