Ukushintshwa kwevolumu yokungenisa kweChina kusuka ngo-2004-2021 kungabonakala ezigabeni ezine ze-China zokungenisa ivolumu yevolumu kusukela ngo-2004, njengoba kuchaziwe ngezansi.

Isigaba sokuqala ngu-2004-2007, lapho isidingo saseChina samapulasitiki sasisezingeni eliphansi futhi ivolumu yokungenisa i-PEE yagcina izinga eliphansi lokusebenza, kanti ivolumu yokungenisa eChina laliphansi ngo-2008 lapho ukufakwa okusha kwasekhaya kwakugxilwe kakhulu futhi kwahlushwa inhlekelele enkulu yezimali.

Isigaba sesibili ngu-2009-2016, ukungeniswa kwe-China's PE kwangena esigabeni esizinzile sokukhula ngemuva kokwanda okukhulu. Ngo-2009, ngenxa ye-bailout efuywayo yasekhaya neyamanye amazwe, ivolumu yezohwebo elijwayelekile lasekhaya landa, ukungenisa okuthe xaxa kwenziwa, ngakho-ke inani lokungenisa liyancipha, ngakho-ke inani lokungenisa liyancipha, ngakho-ke inani lokungenisa liyancipha, ngakho-ke inani lokungenisa liyancishiswa, ngakho-ke inani lokungenisa liyancishiswa, ngakho-ke ivolumu yokungenisa liyancishiswa, ngakho-ke inani lokungenisa liye laqhubeka liphezulu futhi izinga lokukhula laligcina liphezulu futhi izinga lokukhula ligcina Umkhuba ophakeme. Ngo-2014, umthamo omusha wokukhiqiza wasekhaya ukhula kakhulu, futhi ukukhiqizwa kwezinto ezibonakalayo ezibonakalayo ezifuywayo kwanda ngokushesha; Ngo-2016, iNtshonalanga yaphakamisa ngokusemthethweni unswinyo emithonjeni yase-Iran, nasemithonjeni yase-Irani yayizimisele ngokwengeziwe ukuthumela eYurophu ngamanani aphezulu, lapho ukukhula kwevolumu yokungenisa kwasekhaya kwehle.

Isigaba sesithathu ngu-2017-2020, ivolumu ye-China's PE ikhule futhi ngonyaka we-2017, amandla okukhiqiza asekhaya nawokwamanye amazwe ayanda futhi agxile kakhulu ukukhiqizwa kwamandla aphesheya kwezilwandle, kusesekuthekelisa okubalulekile kokukhishwa kwamandla okukhiqiza emhlabeni. 2017 Selokhu kungeniswa i-China Ukukhula kwevolumu ukuthi kukhuphuke kakhulu, kuya ku-2020, kuvulwe amadivaysi amasha aseChina, ngenkathi isimo sokuthola amandla okugcina, lapho kunesimo sokuthola usizo, izinsizakusebenza ze-Overseas zithambekele ekuthengeni emakethe yaseChina ngamanani aphansi, ngakho-ke Ivolumu yokungenisa eChina China ligcina eliphakathi nendawo liye ekukhuleni okuphezulu, kwathi ngevolumu yokungenisa eChina laseChina lifinyelela amathani ayizigidi ezingama-18,53. Kodwa-ke, izici zokushayela zokwanda kwevolumu yokungenisa i-PE kulesi sigaba ikakhulukazi ngokusetshenziswa kwezimpahla kunokuba kuqhutshwe yisidingo esisheshayo, kanye nokucindezela okuncintisanayo okuvela kancane kancane.

Ngo-2021, inkampani yokungenisa impahla yaseChina ingena esigabeni esisha, futhi ngokuya ngezibalo zamabhizinisi, ivolumu yokungenisa ye-China izokuba ngamathani angama-20,59 aphezulu, ivolumu yezigidi ezingama-3,93 lisuka ku-2020. Kuncishiswe kakhulu ngo-2021. Amandla okukhiqiza ama-2022 azoqhubeka nokwandisa, iwindi le-arbitrage ngaphakathi nangaphandle kwemakethe kusenzima ukuvula, ivolumu yokungenisa kwezwe laseChina lizohlala liphansi, futhi ivolumu yokungenisa eChina lizongena esiteshini esingezansi.

Kusukela ngo-2004-2021 China PE athunyelwa ngevolumu yezinhlobo ngalunye, ivolumu yokungenisa ephelele yeChina PE iphansi kanti ama-amplitude makhulu.

Kusukela ngo-2004 kuya ku-2008, ivolumu yokuthumela ngaphandle ye-China yayingaphakathi kwamathani ayi-100,000. Ngemuva kukaJuni 2009, isilinganiso sentela yentela yentela kazwelonke yamapulasitiki athile nemikhiqizo yawo, njengenye i-ethylene armene, yakhulela ku-13%, futhi intshiseko yasekhaya ye-PE ethunyelwa ngentshiseko yanda.

Ngo-2010-2011, ukukhuphuka kokuthekelisa kwasekhaya kusobala, kepha ngemuva kwalokho, ukuthekelisa kwasekhaya kuhlangane negebe lokukhiqiza lase-China, futhi kunzima ukuba nokwanda okukhulu kokuthekelisa ngokususelwa kwizindleko, izidingo zekhwalithi kanye nezingqinamba zezinto zokuhamba.

Kusukela ngo-2011 kuya ku-2020, ivolumu yokuthumela ngaphandle ye-China, iVolumu yayo yokuthumela ngokuyisisekelo yayiphakathi kwamathani angama-200,000 kuya kwangama-300,000. 2021, ivolumu yokuthumela kwelinye izwe laseChina ligxilisiwe, futhi okuthengiswayo okuphelele kwafinyelela amathani angama-510,000, ukukhuphuka kwamathani angama-260,000 ngokuqhathaniswa no-2020, ukukhuphuka ngo-104% unyaka nonyaka.

Isizathu ukuthi ngemuva kuka-2020, izitshalo ezinkulu ze-hydrocarbon zizokwethulwa maphakathi nendawo, futhi amandla okukhiqiza azokhishwa ngempumelelo ngo-2021, futhi ukukhiqizwa kwe-PE yaseChina kuzokwanda, ikakhulukazi izinsizakusebenza ze-HDPE ezihlelelwe ingcindezi yokuncintisana kwemakethe. Ukuhlinzekwa kuyaqina, kanye nokuthengiswa kwezinsizakusebenza zaseChinese PE eSouth America nezinye izindawo ziyanda.

Ukukhula okuqhubekayo kwekhono lokukhiqiza kuyinkinga enkulu okufanele ibhekane nohlangothi oluhlinzekwayo lweShayina Pe. Okwamanje, ngenxa yezingqinamba zezindleko, izimfuno zekhwalithi kanye nezimo zokuhamba, kusenzima ukuthumela amakhaya PE, kodwa ngokukhula okuqhubekayo kwamandla okukhiqiza asekhaya, kubalulekile ukulwela ukuthengiswa kwaphesheya. Ingcindezi yomncintiswano we-Global PE ngokuzayo iya ngokuya iba nzima ngokwengeziwe, futhi iphethini yokuhlinzekwa kanye nokufunwa ezimakethe ezifuywayo nezangaphandle isadinga ukunakwa okwengeziwe.
