In　this　paper,　we　analyze　the　profitability　of　a　monopoly　manufacturer　that　takes　pure-selling,　pure-leasing　and　hybrid　strategy　by　considering　the　capital　constraint　of　the　consumers　and　the　life　span　of　the　product　in　an　indefinite　time　horizon　model.　We　find　that　the　increase　of　the　consumers　with　capital　constraint　has　a　more　significant　impact　on　the　prices　when　the　proportion　of　that　group　is　small.　It　will　curb　the　development　of　the　rental　market;　when　the　group　reaches　a　certain　scale,　then　it　plays　a　leading　role　in　the　demand,　which　encourages　more　manufacturers　to　take　leasing　strategy.　In　the　hybrid　strategy,　we　see　an　explicit　increase　in　the　overall　profit.　We　find　the　leasing　channel　dominates　the　markets　with　the　help　of　C-type　market.　The　suppressed　selling　channel　has　to　lower　the　price　to　keep　the　market　coverage,　which　is　independent　with　the　market　structure.　These　findings　provide　new　insights　for　the　operation　of　large　construction　machinery　manufacturing　companies.　(C)　2019,　IFAC　(International　Federation　of　Automatic　Control)　Hosting　by　Elsevier　Ltd.　All　rights　reserved.
