Background:　The　proportion　of　government　healthcare　expenditure　in　China　increases　due　to　rapid　economic　development　in　recent　years.　The　growth　of　government　healthcare　expenditure　can　promote　physical　health　improvement　of　human　capitals　and　thereby　facilitate　economic　growth.　Hence,　exploring　the　effects　of　government　healthcare　expenditure　on　economic　growth　is　important.　Methods:　Spatial　correlation　of　economic　growth　under　different　spatial　weights　was　tested,　and　the　effects　of　government　healthcare　expenditure　on　economic　growth　were　analyzed　by　constructing　a　spatial　Durbin　model　with　the　panel　data　of　31　provinces　in　China　gathered　from　2005　to　2017.　Results:　Government　healthcare　expenditure　in　China　significantly　and　positively　affects　economic　growth　under　three　spatial　weight　matrices.　The　spatial　weight　of　economic　distance　influences　economic　growth　more　significantly　compared　with　the　0-1　spatial　weight　and　the　spatial　weight　of　geographical　distance.　The　total　and　the　direct　effects　of　government　healthcare　expenditure　are　significantly　positive.　Furthermore,　the　direct　effects　are　significant,　whereas　the　indirect　effects　show　different　degrees　of　significance.　Conclusion:　The　total　effect　of　government　healthcare　expenditure　on　economic　growth　is　significant　and　positive,　with　direct　effects　exceeding　the　indirect　ones.　Hence,　the　China＇s　government　must　continue　to　increase　financial　investment　to　public　health　services　to　promote　high　-quality　economic　growth　in　the　country.
