To　explore　the　innovation　strategy　choices　of　supply　chain　companies　when　lead　users　participate　in　research　and　development,　a　supply　chain　System　consisting　of　a　manufacturer　and　a　retailer　was　constructed,　which　simultaneously　produced　and　sold　both　conventional　products　and　innovative　products　that　were　interchangeable.　The　closed　innovation　strategy,　lead　user　innovation　strategy　and　a　supply　chain　coordination　strategy　based　on　＇cost　sharing　and　benefit　sharing＇　were　proposed.　The　three　strategies　were　compared　and　analyzed　using　Stackeiberg　game　method.　Additionally,　the　impact　of　consumer　heterogeneity　on　supply　chain　innovation　decisions　was　taken　into　consideration,　and　numerical　analysis　was　conducted　on　the　decision　results　with　varying　costs　of　independent　innovation　for　manufacture.　The　results　indicated　that　the　lead　user　innovation　strategy　could　compensate　for　the　short-comings　of　closed　innovation;　the　execution　effectiveness　of　the　innovation　strategy　could　be　improved　by　selecting　lead　users;　changes　in　the　market　and　innovation　strategy　might　impact　supply　chain　decisions　and　conventional　product　pricing;　the　adoption　of　the　＇cost　sharing　and　benefit　sharing＇　model　could　improve　the　profitability　of　the　manufacturer　to　some　extent.　©　2025　CIMS.　All　rights　reserved.
