Izici ezingathandeki nezithandekayo zokuthuthukiswa kwemboni ye-valve kagesi

I-valve kagesi iyisisetshenziswa esibalulekile semishini empilweni yokukhiqiza, esetshenziswa kabanzi kuzo zonke izigaba zokuphila. Kodwa-ke, okwamanje, ukuthuthukiswa kwemboni ye-valve kagesi ezweni lethu akulingani, ngaphansi kwendawo enhle yasekhaya kanye nethemba lokuthuthukiswa, kunezici eziningi ezimbi. 1, izici ezinhle (1) Ithemba "lokuhlaziywa kwe-investimenti ye-valve yase-China ka-2016-2020 kanye nenkulumo yokuqagela okulindelwe" ekhishwe ngabasebenzi be-CIC yathi ngokuphelela kobuchwepheshe be-valve kagesi, ukusetshenziswa kwenkundla yama-valve kagesi kuyaqhubeka nokukhula, futhi usayizi we-valve ohambisanayo uya ngokuya udingeka kakhulu. Imikhiqizo yezimboni zama-valve ingene enkathini yokuqamba izinto ezintsha, akuzona kuphela izinhlobo zemikhiqizo ezidinga ukubuyekezwa futhi zishintshwe, abaphathi bangaphakathi bebhizinisi nabo kudingeka bajule ngokwezinga lemboni. Njengoba ijubane lokuhlelwa kabusha kwemboni ye-valve kagesi liqhubeka nokusheshisa, ukuncintisana phakathi kwemboni ye-valve esikhathini esizayo kuyoba ukuncintisana phakathi kwekhwalithi nomkhiqizo womkhiqizo wemikhiqizo ye-valve kagesi, imikhiqizo izothuthukiswa ekuqondisweni kobuchwepheshe obuphezulu, imingcele ephezulu, ukumelana nokuguguleka okuqinile, ukuphila isikhathi eside. Imboni yokukhiqiza ama-valve yasekhaya endaweni efunwa kakhulu, izophinde ilethe ithemba lentuthuko elihle kakhulu. Ngakho-ke, sidinga ukusebenzisa ngokugcwele isikali esikhona ngesikhathi esifanayo, sibheke esikhathini esizayo, ucwaningo lungasetshenziswa esikhathini esizayo sesilinganiso esisha nohlelo olusha, ukuze kuthuthukiswe ukuthuthukiswa kobuchwepheshe be-valve endaweni ephakeme. izinga. (2) Izimboni zamakhemikhali nezamandla seziphenduke izindawo ezintsha zokukhula kwemakethe yamavalvu. Isikhathi eside, isidingo samavalvu kagesi embonini yamandla siye sagcina izinga lokukhula eliqinile nelizinzile. Kunezi-2,679,030 MW zezikhungo zamandla ashisayo nawenuzi ezisakhiwa emhlabeni wonke, 743,391 MW e-United States, kanye nama-780,000 MW wamaphrojekthi wesikhungo sokuphehla amandla amasha emhlabeni wonke, azokhula ngama-40% eminyakeni embalwa ezayo. I-Europe, iNingizimu Melika, i-Asia, ikakhulukazi imakethe yamandla yaseChina izoba yindawo entsha yokukhula yemakethe yama-valve. Imboni yamakhemikhali isezingeni embonini ngenani eliphumayo elingaphezu kwamadola ayizigidi eziyizinkulungwane eziyi-1.5 futhi ingenye yezimakethe ezinkulu zokufunwa kwamavalvu. Imboni yamakhemikhali idinga ukuklama okuvuthiwe, izinga eliphezulu lokucubungula, izinto ezingavamile ze-valve yemboni. Eminyakeni yamuva nje, ukuncintisana kwemakethe yamakhemikhali kuye kwashuba kakhulu, abakhiqizi bamakhemikhali abaningi ababhekene nokuncintisana kufanele banciphise ukusetshenziswa kwezimali. 2, izici ezingezinhle (1) Ukuntuleka kwamakhono ochwepheshe sekuphenduke umgoqo ovimbela ukuqhubeka kwemboni yamavalvu kagesi ezweni lakithi. Ukuthuthukiswa nokukhula kwemboni yama-valve akuhlukaniseki nokutshalwa kwezimali kwamathalente asezingeni eliphezulu. Kufanele sifunde ukwaba nokuwasebenzisa ngokwesayensi amakhono, sisebenzise izinto ngendlela engcono kakhulu, abantu bawasebenzise kahle kakhulu amakhono, futhi sinake ukukhuliswa kwamathalenta. Ukuthuthukiswa kwemboni akuhlukaniseki nethalente, ukuthi ungaqinisekisa kanjani ukuthi ithimba lonke labasebenzi alinasiphithiphithi yiwo wonke ama-opharetha okukhiqiza kufanele acabangele isihloko. Ukuthuthukiswa kweThe Times, ukuthuthukiswa kwesayensi nobuchwepheshe kuqokonyiswa njengokuthi "okusha", ukuqamba okusha okuqhubekayo kungagcina ukuncintisana kokuthuthukiswa kwezimboni, kungaba yonke indawo, kungaba nendlela engcono yokuphuma. (2) Ukuncintisana kwemakethe okuqinile i-valve kagesi ingumkhiqizo wemali ephansi yenzuzo, ukuncintisana kwemakethe kunamandla kakhulu. Njengamanje, imboni yama-valve kagesi yaseShayina iyimboni edinga abasebenzi abaningi, futhi imboni yamavalvu kagesi isasekelwe ikakhulukazi ekwandeni kobuningi. Imakethe yangaphandle isebenza kakhulu eminyakeni yamuva futhi ukuncintisana kushubile. I-East Asia kanye ne-Southeast Asia's electric valve import and export growth is ngokushesha, North America's European Community kanye namanye amazwe athuthukile phakathi kwebhizinisi lemakethe laqhubeka nentuthuko, iJalimane, i-Italy, iJapane, i-China namanye amazwe kanye nezifunda ukuze kwandiswe ukuthunyelwa kwamanye amazwe, i-United States, iBrithani. , France kanye namanye amazwe ukungena ekukhuleni okusheshayo, kwakheka ukuchuma kwemakethe ye-valve yamazwe omhlaba iphuzu lokusekela, ngaphezu kwalokho, ngenxa yokuthi umnotho wezwe uqhubeka nokuhwebelana kwamanye amazwe, izinkampani zamazwe ngamazwe zizoqhubeka nokukhuthaza ukuthuthukiswa kwemakethe ye-valve yamazwe ngamazwe, ukuhlukaniswa kwebhizinisi kwamanye amazwe kubophezelekile ube esinye isici esikhulu. Nakuba imisebenzi yemakethe ye-valve yamazwe ngamazwe ekhiqizwa eChina imikhiqizo eminingi ye-valve, kodwa amandla enkulumo emakethe ye-valve yamazwe ngamazwe awekho ezandleni zamabhizinisi aseShayina. (3) Umkhiqizo uhlehle emuva futhi ukuthuthukiswa akulingani. I-"2016-2020 China Electric Valve Industry Analysis and Speculation Speech" ekhishwe Abasebenzi be-CIC ithe ukuthuthukiswa kwezinga kanye nebanga lomkhiqizo wamavalvu kagesi kuyinkinga eyinhloko ekuthuthukisweni kwesikhathi esizayo kwemboni yamavalvu kagesi. ezweni lakithi. Ukudangala kwayo yonke imboni yamavalvu kagesi, kuholela ekuhlehleni kwemikhiqizo yamavalvu ezweni lakithi, okuyisici esibalulekile esivimbela ukuthuthukiswa kwemikhiqizo yethu yamavalvu. Phambilini ibibanjwe iphrojekthi "yokudluliswa kwegesi eNtshonalanga iye eMpumalanga", amabhizinisi amaningi endawo ayigeje. Ngaphezu kwezinto ezithinta imvelo, ezinye izinto, njengemishini ebuyela emuva kanye nobuchwepheshe, izinga eliphansi lokukhethekile, usayizi wemakethe encane nezinye izici nazo zikhawulela ukuthuthukiswa kwebhodlela lemboni yama-valve. Embonini yasekhaya yamavalvu kagesi, kukhona negebe elikhulu phakathi kwezwekazi kanye nogu. Indawo yokuqala yomkhakha wama-valve ezwenikazi iphansi, isikali sincane, izinga lokukhethekile liphansi, futhi izinga lokumaketha aliphezulu, okukhulise igebe ngendawo yasogwini, kodwa futhi kwaholela ekuthuthukisweni okungalingani. wemboni ye-valve olwandle. (4) Ukuncintisana okubi Kunokuncintisana okubi embonini. Isibonelo, abaphathi bomnyango bavuselela futhi balungise ama-valve asetshenzisiwe futhi bawadayise okwesibili ngemva kokulungiswa kabusha, okuletha ubungozi obukhulu kakhulu bokuphepha kukhwalithi yephrojekthi futhi kuphazamisa kakhulu ukuhleleka nokuqina kwemakethe yama-valve.
