Shanduko yevhoriyamu yekupinda kunze kweChina kubva muna 2004-2021 inogona kuoneka muzvikamu zvina zveChinese PE yekupinda vhoriyamu maitiro kubvira 2004, sekutsanangurwa pazasi.

Nhanho yekutanga ndeye 2004-2007, apo kudiwa kweChina kwemapurasitiki kwaive kwakadzikira uye PE yekupinza vhoriyamu yakaramba yakadzikira, uye huwandu hweChina hwekupinza PE hwakanga hwakaderera muna 2008 apo kuisirwa kutsva kwemba kwakawedzera uye kutambura nedambudziko remari.

Chikamu chechipiri ndeche 2009-2016, PE yeChina yekunze yakapinda muchikamu chekukura chakagadzikana mushure mekuwedzera kukuru. 2009, nekuda kweiyo yepamba uye yekunze mari jekiseni jekiseni, hupfumi hwepasi rose, kutengeserana kwepasi rose kwakawedzera, kudiwa kwekufungidzira kwaipisa, kutengwa kunze kwenyika kwakawedzera zvakanyanya, nekukura kwe64.78%, kuchiteverwa nekuchinja kwekuchinja muna 2010, iyo RMB exchange. chiyero chakaramba chichikoshesa, pamwe chete neASEAN Free Trade Area Chibvumirano chehurongwa chakatanga kushanda uye mutengo wekutumira wakaderedzwa, saka huwandu hwekutumira kubva ku2010 kusvika 2013 yakaramba yakakwira uye chiyero chekukura chakaramba chiri chepamusoro. Pakazosvika 2014, hutsva hutsva hwekugadzira PE hwakawedzera zvakanyanya, uye kugadzirwa kwezvinhu zvemukati-chinangwa kwakawedzera nekukurumidza; mu 2016, West pamutemo akasimudza zvirango pamusoro Iran, uye Iranian manyuko vakanga zvikuru kuda ekisipoti kuEurope pamwe yakakwirira mitengo, panguva iyo kukura mudzimba import vhoriyamu akadonha shure.

Nhanho yechitatu ndeye 2017-2020, China PE yekupinda vhoriyamu yakawedzera zvakanyanya muna 2017, yemukati neyekunze PE yekugadzira kugadzirwa kuri kuwedzera uye yakanyanyisa kugadzirwa mhiri kwemakungwa, China, senyika huru inodya PE, ichiri yakakosha kunze kwenyika kugadzirwa kwepasirese. release. 2017 kubva kuChina PE yekupinda vhoriyamu yekukura kutsetseka kwakawedzera zvakanyanya, kusvika 2020, China yakakura yekunatsa uye yakareruka hydrocarbon michina mitsva yakatangwa, yepamba Zvisinei, kubva pamaonero ekushandiswa, kudiwa kwemhiri kwemakungwa kunonyanya kukanganiswa ne "denda idzva rekorona", nepo. mamiriro ekudzivirira uye kutonga kwechirwere cheChina akadzikama uye kudiwa kunotungamira mukupora, zviwanikwa zvemhiri kwemakungwa zvinonyanya kuda. kuendesa kumusika weChinese nemitengo yakaderera, saka China yePE yekupinza vhoriyamu inochengetedza pakati kusvika pakakwirira kukura, uye muna 2020 China's PE import volume inosvika 18.53 miriyoni matani. Nekudaro, izvo zvinotyaira zvekuwedzera kwePE yekupinda vhoriyamu panguva ino ndeyekudyiwa kwezvinhu kwete kufambiswa nezvinodiwa ipapo, uye kumanikidzwa kwemakwikwi kubva kumisika yese yepamba nekumhiri kwemakungwa kunobuda zvishoma nezvishoma.

Muna 2021, maitiro ekuChina ekuunza PE anopinda muchikamu chitsva, uye maererano nehuwandu hwetsika, huwandu hweChina hwekupinza kwePE huchava matani 14.59 miriyoni muna 2021, pasi 3.93 miriyoni matani kana 21.29% kubva 2020. Nekuda kwesimba redenda repasi rose, pasi rose, pasi rose kutakura huwandu hwakasimba, chiyero chekutakura zvinhu mugungwa chakawedzera zvakanyanya, kupindirana nesimba re inverse mutengo we polyethylene mukati nekunze kwemusika, yemukati PE yekupinza vhoriyamu ichaderedzwa zvakanyanya muna 2021. 2022 China yekugadzira hunyanzvi icharamba ichiwedzera, iyo arbitrage hwindo mukati nekunze kwemusika ichiri kunetsa kuvhura, yepasi rose PE yekupinza vhoriyamu icharamba ichiwedzera. yakaderera, uye China PE yekupinda vhoriyamu inogona kupinda yakadzika chiteshi mune ramangwana.

Kubva 2004-2021 China PE kunze kwehuwandu hwemhando yega yega, huwandu hwese hwekupinza kweChina PE hwakaderera uye amplitude yakakura.

Kubva 2004 kusvika 2008, China PE yekutumira vhoriyamu yaive mukati me100,000 matani. Mushure meChikumi 2009, mutero wenyika wekudzoreredzwa kwemutero wemamwe mapurasitiki uye zvigadzirwa zvawo, senge mamwe maethylene polymers ekutanga, akakwidziridzwa kusvika pa13%, uye kufarira kwekunze kwePE kunze kwenyika kwakawedzera.

Muna 2010-2011, kuwedzera kwekutengesa kunze kwenyika PE kwaive pachena, asi mushure mezvo, kunze kwenyika PE kunze kwakasangana nebhodhoro zvakare, kunyangwe nekuwedzera kwekugadzira PE mudzimba, kuchine gaka rakakura muChina PE, uye zvakaoma kuva nazvo. kuwedzera kukuru kwekutengesa kunze kwenyika zvichienderana nemutengo, kudiwa kwemhando uye zvipingamupinyi zvemamiriro ekufambisa.

Kubva 2011 kusvika 2020, vhoriyamu yekuChina yekutumira kunze kwenyika yakawedzera zvishoma, uye huwandu hwayo hwekutumira kunze hwaive pakati pe200,000-300,000 matani. 2021, China PE yekutumira vhoriyamu yakawedzera, uye iyo yakazara kunze kwenyika kunze kwenyika yakasvika 510,000 matani, kuwedzera kwe260,000 matani zvichienzaniswa ne2020, kuwedzera kwe104% gore-pagore.

Chikonzero ndechekuti mushure me2020, maChina makuru ekunatsa uye akareruka hydrocarbon zvidyarwa zvichatangwa pakati, uye huwandu hwekugadzira huchaburitswa zvinobudirira muna 2021, uye kugadzirwa kweChina kwePE kuchawedzera, kunyanya HDPE marudzi, aine zvimwe zviwanikwa zvakarongerwa zvidyarwa zvitsva uye kuwedzera. kumanikidzwa kwemakwikwi emusika. Kupihwa kuri kusimba, uye kutengeswa kweChinese PE zviwanikwa kuSouth America nedzimwe nzvimbo kuri kuwedzera.

Kuenderera mberi kwekukura kwehuwandu hwekugadzira idambudziko rakakura rinofanirwa kutarisana nedivi rekupa reChinese PE. Parizvino, nekuda kwezvipingamupinyi zvemutengo, kudiwa kwemhando uye mamiriro ekufambisa, zvichiri kunetsa kutumira kunze kwenyika PE, asi nekuenderera mberi kwekukura kwesimba rekugadzira mudzimba, zvakakosha kuyedza kutengesa mhiri kwemakungwa. Dzvinyiriro yemakwikwi epasi rose ePE mune ramangwana iri kuramba ichiwedzera, uye maitiro ekupa uye kudiwa mumisika yepamba nekunze ichiri kuda kutariswa.
