Utshintsho lwexabiso lokungenisa elizweni laseTshayina ukusuka ku-2004-2021 lunokubonwa kwizigaba ezine zendlela yomthamo wokungenisa we-PE waseTshayina ukusukela ngo-2004, njengoko kuchaziwe ngezantsi.

Inqanaba lokuqala ngo-2004-2007, xa imfuno yaseChina yeeplastiki yayiphantsi kwaye umthamo wokungenisa i-PE wagcina umgangatho ophantsi wokusebenza, kunye nomthamo we-PE yokungenisa waseTshayina wawuphantsi ngo-2008 xa ufakelo olutsha lwasekhaya lwalugxininise kakhulu kwaye lufumana ubunzima obukhulu bezemali.

Inqanaba lesibini ngo-2009-2016, ukuthengwa kwe-PE yase-China kungene kwinqanaba lokukhula elizinzileyo emva kokunyuka okuphawulekayo.Ngo-2009, ngenxa yebheyile yemali yangaphakathi neyangaphandle, uqoqosho lwehlabathi, umthamo worhwebo wasekhaya ngokubanzi unyukile, imfuno eqikelelwayo yayishushu, ukuthengwa kwempahla kumazwe angaphandle kwanda kakhulu, ngesantya sokukhula sama-64.78%, kulandelwa yireform yotshintsho ngo-2010, utshintshiselwano lwe-RMB. izinga liqhubekile lixabisa, lidityaniswa ne-ASEAN Free Trade Area Isivumelwano sesakhelo saqala ukusebenza kwaye iindleko zokungenisa ziye zancitshiswa, ngoko ke umthamo wokungenisa elizweni ukusuka kwi-2010 ukuya kwi-2013 yahlala iphezulu kwaye izinga lokukhula ligcine umkhwa ophezulu.Ngo-2014, umthamo omtsha wemveliso ye-PE yasekhaya uye wanda kakhulu, kwaye imveliso yasekhaya yenjongo jikelele yanda ngokukhawuleza;in 2016, i-West ngokusesikweni waphakamisa izohlwayo Iran, kunye nemithombo Iranian babezimisele ngakumbi ukuthumela eYurophu kunye namaxabiso aphezulu, ngelo xesha ukukhula umthamo yokungenisa yasekhaya lehla umva.

Inqanaba lesithathu yi-2017-2020, umthamo wokungenisa we-PE waseTshayina wavuka ngokukhawuleza kwakhona ngo-2017, amandla okuvelisa i-PE yasekhaya nakwamanye amazwe ayakhula kwaye agxininise ngakumbi imveliso yaphesheya, iChina, njengelizwe elitya kakhulu i-PE, iseyimveliso ebalulekileyo yokuthumela ngaphandle kwimveliso yehlabathi. khulula.I-2017 ukususela kwi-slope ye-PE yokungenisa umthamo we-PE yokungenisa i-China yanda kakhulu, ukuya ku-2020, ukulungiswa kwe-hydrocarbon enkulu kunye nokukhanya kwezixhobo ezintsha ze-hydrocarbon ziye zasungulwa, zasekhaya Nangona kunjalo, ngokwembono yokusetyenziswa, imfuno yaphesheya ichaphazeleka kakhulu yi "ubhubhani wesithsaba esitsha", ngelixa. Imeko yothintelo kunye nolawulo lobhubhane lwaseTshayina luzinzile kwaye imfuno ikhokela ekubuyiseni, izixhobo zaphesheya zityekele ngakumbi ekuboneleleni kwimarike yaseTshayina ngamaxabiso aphantsi, ke ngoko umthamo wokungenisa we-PE waseTshayina ugcina ukukhula okuphakathi ukuya phezulu, kwaye ngo-2020 i-PE yaseTshayina. umthamo wokungenisa elizweni ufikelela kwi-18.53 yezigidi zeetoni.Nangona kunjalo, izinto eziqhuba ukunyusa umthamo we-PE wokungenisa kweli nqanaba ubukhulu becala zezokusetyenziswa kwempahla endaweni yokuqhutywa yimfuno ekhawulezileyo, kunye noxinzelelo lokukhuphisana oluvela kwiimarike zasekhaya kunye naphesheya kancinci kancinci.

Ngo-2021, i-PE yokungenisa yaseTshayina ingena kwisigaba esitsha, kwaye ngokweenkcukacha-manani zesiko, umthamo wokungenisa we-PE wase-China uya kuba malunga ne-14.59 yezigidi zeetoni ngo-2021, phantsi kwe-3.93 yezigidi zeetoni okanye i-21.29% ukususela ngo-2020. Ngenxa yempembelelo yobhubhane lwehlabathi, ngamazwe ngamazwe umthamo wokuthutha uqinile, izinga lokuthutha ulwandle liye landa kakhulu, lihamba kunye nefuthe lexabiso eliphambeneyo le-polyethylene ngaphakathi nangaphandle kwemarike, umthamo wasekhaya we-PE wokungenisa uya kuncitshiswa kakhulu ngo-2021. ngaphakathi nangaphandle kwimarike kusenzima ukuyivula, umthamo wamazwe ngamazwe we-PE wokungenisa elizweni uya kuhlala uphantsi, kwaye umthamo wokungenisa waseTshayina we-PE unokungena kumjelo wokuhla kwixesha elizayo.

Ukususela kwi-2004-2021 i-China PE umthamo wokuthumela ngaphandle kweentlobo nganye, umthamo wokungenisa jikelele we-China PE uphantsi kwaye i-amplitude inkulu.

Ukusukela ngo-2004 ukuya ku-2008, umthamo wokuthumela ngaphandle kwe-PE yaseTshayina wawuphakathi kweetoni ezili-100,000.Emva kweyeSilimela ka-2009, izinga lesaphulelo serhafu yelizwe kwezinye iiplastiki kunye neemveliso zazo, ezifana nezinye iipholima ze-ethylene ezimile okweprayimari, zanyuswa zaya kutsho kwi-13%, kwaye umdla wangaphakathi we-PE wokuthumela ngaphandle unyukile.

Ngo-2010-2011, ukonyuka kokuthunyelwa kwe-PE yasekhaya kwakucacile, kodwa emva koko, ukuthunyelwa ngaphandle kwe-PE yasekhaya kuphinde kwadibana ne-bottleneck, ngaphandle kokunyuka kwamandla emveliso ye-PE yasekhaya, kusekho umsantsa omkhulu kwi-PE yase-China, kwaye kunzima ukuba nayo. ukwanda okukhulu kokuthunyelwa kwempahla kumazwe angaphandle ngokusekelwe kwiindleko, imfuno yomgangatho kunye nemiqobo yemeko yothutho.

Ukusukela ngo-2011 ukuya kowama-2020, umthamo wokuthumela ngaphandle kwe-PE yaseTshayina uye wacutheka kancinci, kwaye umthamo wokuthumela ngaphandle wawuphakathi kwe-200,000-300,000 yeetoni.Ngo-2021, umthamo wokuthumela ngaphandle we-PE waseTshayina uye wanda, kwaye inani lokuthunyelwa kwempahla ngaphandle konyaka lilonke lafikelela kwiitoni ezingama-510,000, ukwanda kweetoni ezingama-260,000 xa kuthelekiswa no-2020, ukonyuka kwe-104% unyaka nonyaka.

Isizathu kukuba emva kwe-2020, izityalo ezinkulu zaseChina zokusulungekisa kunye nokukhanya kwe-hydrocarbon ziya kuqaliswa embindini, kwaye umthamo wemveliso uya kukhutshwa ngokufanelekileyo kwi-2021, kunye nemveliso ye-PE yaseChina iya kwanda, ngakumbi iintlobo ze-HDPE, kunye nezibonelelo ezininzi ezicwangciselwe izityalo ezintsha kunye nokwanda. uxinzelelo lokhuphiswano lwemarike.Unikezelo luqiniswa, kwaye ukuthengiswa kwezixhobo ze-PE zaseTshayina eMzantsi Melika nakwezinye iindawo kuyanda.

Ukukhula okuqhubekayo komthamo wemveliso yingxaki enzima ekufuneka ijongane nayo kwicala lokubonelela nge-PE yaseTshayina.Okwangoku, ngenxa yeengxaki zeendleko, imfuno yomgangatho kunye neemeko zokuhamba, kusenzima ukuthumela ngaphandle kwe-PE yasekhaya, kodwa ngokukhula okuqhubekayo komthamo wemveliso yasekhaya, kubalulekile ukuzama ukuthengisa phesheya.Uxinzelelo lokhuphiswano lwehlabathi lwe-PE kwixesha elizayo luya lusiba qatha ngakumbi, kwaye ipateni yobonelelo kunye nemfuno kwiimarike zasekhaya nezangaphandle isafuna ukuqwalaselwa ngakumbi.
