Based　on　the　panel　data　of　carbon　emissions　in　30　regions　of　China　from　2007　to　2018,spatial　Dubin　econometric　models　are　used　to　empirically　analyze　the　key　factors　affecting　China　＇s　carbon　emissions　and　impact　mechanism,　focusing　on　government　environmental　regulations　and　service　industries　agglomeration　including　hidden　economy.　The　results　show　that　there　is　a　significant　space　spillover　effect　of　carbon　emissions,　which　is　manifested　as　the　mutual　influence　of　the　local　and　surrounding　areas.　Environmental　regulation　reduces　the　level　of　carbon　emissions　through　administrative　measures,　but　due　to　the　existence　of　hidden　economic　negative　effects,　the　interaction　has　a　promoting　effect　on　carbon　emissions;　service　industry　agglomeration　has　certain　carbon　emission　reduction　effect,　but　only　the　agglomeration　of　producer　services　can　significantly　suppress　carbon　emissions,　consumer　services　and　public　services　increase　carbon　emissions.　©　2020　ACM.
