Kev hloov pauv ntawm Tuam Tshoj cov khoom lag luam ntshuam los ntawm 2004-2021 tuaj yeem pom nyob rau hauv plaub theem ntawm Tuam Tshoj tus PE ntshuam ntim qauv txij li xyoo 2004, raws li cov lus qhia hauv qab no.

Thawj theem yog xyoo 2004-2007, thaum Tuam Tshoj qhov kev thov rau plastics tsawg thiab PE ntshuam ntim tau tuav qis qis ntawm kev ua haujlwm, thiab Tuam Tshoj tus PE ntshuam ntim qis hauv xyoo 2008 thaum cov khoom siv hauv tsev tshiab tau ntau dua thiab raug kev txom nyem nyiaj txiag loj.

Lub sijhawm thib ob yog xyoo 2009-2016, Tuam Tshoj tus PE cov khoom lag luam nkag mus rau theem kev loj hlob ruaj khov tom qab muaj kev nce ntxiv. Nyob rau hauv 2009, vim lub domestic thiab txawv teb chaws peev nyiaj bailout, ntiaj teb no liquidity, domestic dav dav kev lag luam ntim tau nce, speculative xav tau kub, ntshuam nce loj, nrog rau kev loj hlob ntawm 64.78%, tom qab ntawd los ntawm kev hloov pauv tus nqi xyoo 2010, RMB pauv tus nqi txuas ntxiv, ua ke nrog ASEAN Free Trade Area Daim ntawv cog lus tau pib ua haujlwm thiab cov nqi ntshuam 10 tau txo qis, yog li 20 ntshuam 10 ntsoog 2. thiab qhov kev loj hlob tau tuav ib qho kev sib tw siab. Los ntawm xyoo 2014, lub peev xwm tsim khoom hauv tsev tshiab PE tau nce ntau, thiab cov khoom siv dav dav hauv tsev tau nce sai; Xyoo 2016, Sab Hnub Poob tau tshem tawm kev rau txim rau Iran, thiab Iranian cov peev txheej tau txaus siab xa tawm mus rau Tebchaws Europe nrog tus nqi siab dua, thaum lub sijhawm kev loj hlob ntawm cov khoom lag luam hauv tebchaws tau poob rov qab.

Qhov thib peb theem yog 2017-2020, Tuam Tshoj tus PE ntshuam ntim tau nce siab dua nyob rau hauv 2017, domestic thiab txawv teb chaws PE ntau lawm muaj peev xwm nce thiab ntau concentrated txawv teb chaws ntau lawm, Tuam Tshoj, raws li ib tug loj PE siv lub teb chaws, tseem yog ib qho tseem ceeb export rau ntiaj teb no ntau lawm muaj peev xwm tso tawm. 2017 txij li Tuam Tshoj tus PE ntshuam ntim kev loj hlob txoj kab nqes nce ntxiv, mus rau 2020, Tuam Tshoj txoj kev kho kom zoo thiab lub teeb hydrocarbon tshiab cov cuab yeej tau raug tsim tawm, hauv tsev Txawm li cas los xij, los ntawm kev xav ntawm kev noj, kev thov txawv teb chaws muaj kev cuam tshuam ntau dua los ntawm "cov kab mob tshiab tshiab", thaum qhov xwm txheej ntawm Tuam Tshoj txoj kev tiv thaiv kab mob sib kis thiab kev tswj hwm yog qhov ruaj khov thiab kev xav tau ntau dua. kev lag luam ntawm tus nqi qis, yog li Tuam Tshoj tus PE ntshuam ntim tswj nruab nrab mus rau kev loj hlob siab, thiab xyoo 2020 Tuam Tshoj tus PE ntshuam ntim tau nce mus txog 18.53 lab tons. Txawm li cas los xij, kev tsav tsheb rau qhov nce ntawm PE ntshuam ntim ntawm theem no yog qhov tseem ceeb rau kev noj cov khoom es tsis yog tsav los ntawm qhov kev thov tam sim, thiab kev sib tw los ntawm kev lag luam hauv tsev thiab txawv teb chaws maj mam tshwm sim.

Xyoo 2021, Tuam Tshoj tus PE ntshuam qauv nkag mus rau theem tshiab, thiab raws li kev lis kev cai txheeb cais, Tuam Tshoj tus PE ntshuam ntim yuav yog kwv yees li 14.59 lab tons hauv 2021, nqis 3.93 lab tons lossis 21.29% los ntawm 2020. Vim muaj kev cuam tshuam ntawm kev sib kis thoob ntiaj teb, thoob ntiaj teb kev thauj khoom muaj peev xwm nruj, nqes dej hiav txwv nce ntxiv ntawm tus nqi, kev cuam tshuam ntawm kev thauj mus los thoob ntiaj teb. polyethylene sab hauv thiab sab nraud kev ua lag luam, domestic PE ntshuam ntim yuav txo qis hauv 2021. 2022 Tuam Tshoj lub peev xwm ntau lawm yuav txuas ntxiv nthuav dav, lub qhov rais arbitrage sab hauv thiab sab nraum kev lag luam tseem nyuaj rau qhib, thoob ntiaj teb PE ntshuam ntim yuav nyob qis, thiab Tuam Tshoj tus PE ntshuam ntim tuaj yeem nkag mus rau hauv nqes channel yav tom ntej.

Los ntawm 2004-2021 Tuam Tshoj PE export ntim ntawm txhua hom, tag nrho cov ntshuam ntawm Tuam Tshoj PE yog tsawg thiab lub amplitude yog loj.

Los ntawm 2004 txog 2008, Tuam Tshoj tus PE export ntim nyob rau hauv 100,000 tons. Tom qab Lub Rau Hli 2009, lub teb chaws xa tawm cov nqi se rov qab rau qee cov yas thiab lawv cov khoom lag luam, xws li lwm yam zoo li ethylene polymers, tau nce mus rau 13%, thiab cov khoom lag luam PE hauv tsev tau nce ntxiv.

Hauv xyoo 2010-2011, qhov nce ntawm PE xa tawm hauv tsev tau pom tseeb, tab sis tom qab ntawd, kev xa tawm hauv tsev PE tau ntsib teeb meem dua, txawm tias muaj peev xwm ua tau PE ntau lawm, tseem muaj qhov sib txawv loj hauv Suav teb PE muab khoom, thiab nws nyuaj rau muaj qhov nce loj hauv kev xa tawm raws li tus nqi, kev xav tau thiab kev thauj mus los tsis zoo.

Los ntawm 2011 txog 2020, Tuam Tshoj tus PE export ntim oscillated nqaim, thiab nws export ntim tau pib ntawm 200,000-300,000 tons. 2021, Tuam Tshoj tus PE xa tawm ntim tau nce, thiab tag nrho cov khoom xa tawm txhua xyoo mus txog 510,000 tons, nce 260,000 tons piv nrog 2020, nce 104% xyoo-rau-xyoo.

Yog vim li cas yog tias tom qab xyoo 2020, Tuam Tshoj txoj kev kho kom zoo nkauj loj thiab lub teeb hydrocarbon cov nroj tsuag yuav pib ua haujlwm hauv nruab nrab, thiab cov peev txheej tsim tawm yuav ua tau zoo nyob rau xyoo 2021, thiab Tuam Tshoj cov khoom siv PE yuav nce ntxiv, tshwj xeeb tshaj yog HDPE ntau yam, nrog rau ntau cov peev txheej rau cov nroj tsuag tshiab thiab nce kev sib tw ua lag luam siab. Cov khoom siv tau nruj, thiab kev muag khoom ntawm Suav PE cov peev txheej rau South America thiab lwm qhov chaw yog nce.

Kev loj hlob tsis tu ncua ntawm kev tsim muaj peev xwm yog ib qho teeb meem loj uas yuav tsum tau ntsib ntawm cov khoom siv ntawm Suav PE. Txog tam sim no, vim muaj kev txwv ntawm tus nqi, kev xav tau zoo thiab kev thauj mus los, nws tseem nyuaj rau kev xa tawm PE hauv tsev, tab sis nrog kev loj hlob tsis tu ncua ntawm kev tsim khoom hauv tsev, nws yog ib qho tseem ceeb rau kev siv zog rau kev muag khoom txawv teb chaws. Lub siab ntawm kev sib tw PE thoob ntiaj teb yav tom ntej tau dhau los ua hnyav dua, thiab cov qauv ntawm cov khoom siv thiab kev thov hauv kev lag luam hauv tsev thiab txawv teb chaws tseem xav tau kev saib xyuas ntxiv.
