Construction　activities　have　a　significant　impact　on　the　environment,　green　cooperation　is　an　important　way　to　promote　the　green　performance　of　construction　projects.　Based　on　a　Stackelberg　model　between　the　leader　and　members,　green　effort　decision　is　analyzed　in　two　fairness　reference　situations,　one　is　the　absolute　fairness　situation,　taking　the　leader＇s　profit　as　reference　point,　the　other　is　the　relative　fairness　situation,　taking　the　Nash　bargaining　solution　as　reference　point.　Research　findings　are　as　follows:　fairness　preference　will　affect　green　effort　decisions　of　construction　project　participants,　but　the　effect　is　related　to　the　fairness　reference　point　and　profit　distribution.　Green　effort　decisions　in　different　fairness　reference　situations　are　related　with　the　critical　point　of　income　distribution,　therefore,　the　fairness　reference　point　and　critical　point　of　income　distribution　should　be　taken　into　account　when　designing　income　distribution　plan,　for　the　purpose　of　effective　induction　of　green　efforts.　©　2018,　Editorial　Office　of　Control　and　Decision.　All　right　reserved.
