In　this　paper,　we　explore　how　a　monopoly　manufacturer　chooses　the　market　strategies　and　decides　the　optimal　price　to　obtain　maximum　profit.　We　divide　the　market　into　the　C-type　market　and　the　N-type　market,　and　analyze　the　profitability　of　the　monopoly　manufacturer　who　takes　the　pure-selling,　pure-leasing　and　hybrid　strategy　respectively,　considering　consumers＇　capital　constraint　and　the　life　span　of　the　durable　goods　in　an　indefinite　time　horizon　model.　(1)　We　find　that　a　larger　proportion　of　the　consumers　with　capital　constraint　has　a　more　significant　impact　on　the　prices　and　it　could　slow　down　the　development　of　the　rental　market.　When　the　scale　of　the　group　attains　up　to　a　threshold　level,　it　would　greatly　influence　the　customers＇　demand　and　their　marketing　strategy,　and　encourages　more　manufacturers　to　take　the　leasing　strategy.　(2)　In　the　Hybrid　Strategy,　we　see　explicit　growth　in　the　overall　profit　with　both　the　leasing　channel　and　the　selling　channel　working　together,　although　the　former　outperforms　the　latter.　The　suppressed　selling　channel,　in　fact,　has　to　lower　the　price　to　keep　the　market　coverage,　with　an　independent　market　structure.　(3)　Finally,　we　find　that　a　leasing　agent　may　help　the　manufacturer　at　first　and　then　become　a　tough　competitor.　These　findings　provide　new　insights　for　the　operation　of　large　construction　machinery　manufacturing　companies.　subject　classification　numbers　as　needed.
