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 kev txhaj tshuaj bailout, ntiaj teb no liquidity, domestic kev lag luam ntim tau nce, speculative xav tau kub, imports nce ho, nrog ib tug loj hlob npaum li cas ntawm 64.78%, tom qab ntawd los ntawm kev hloov pauv tus nqi xyoo 2010, RMB pauv. tus nqi txuas ntxiv kom txaus siab, ua ke nrog ASEAN Free Trade Area Daim ntawv cog lus tau pib ua haujlwm thiab tus nqi ntshuam tau txo qis, yog li cov khoom ntim ntawm 2010 txog 2013 tseem siab. 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 noj 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 nqes zuj zus, mus rau 2020, Tuam Tshoj lub loj refining thiab lub teeb hydrocarbon cov cuab yeej tshiab 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 loj 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 coj tus thawj coj hauv kev rov qab los, cov peev txheej txawv teb chaws muaj kev xav ntau dua los muab rau Suav. 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 li ntawm 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. shipping peev yog nruj, dej hiav txwv freight tus nqi tau nce ho, overlapping nrog tus nqi ntawm inverse nqi ntawm polyethylene sab hauv thiab sab nraud kev ua lag luam, domestic PE ntshuam ntim yuav txo qis nyob rau hauv 2021. 2022 Tuam Tshoj lub peev xwm ntau lawm yuav txuas ntxiv mus, lub qhov rais arbitrage sab hauv thiab sab nraum lub lag luam tseem nyuaj rau qhib, thoob ntiaj teb PE ntshuam ntim yuav nyob twj ywm tsawg, 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.

Nyob rau hauv 2010-2011, qhov nce ntawm domestic PE export yog pom tseeb, tab sis tom qab ntawd, domestic PE export ntsib fwj dua, txawm tias muaj peev xwm nce PE hauv tsev, tseem muaj qhov sib txawv loj hauv Suav teb PE khoom, thiab nws nyuaj rau muaj. nce loj hauv kev xa tawm raws li tus nqi, kev xav tau zoo thiab kev txwv kev thauj mus los.

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 qhov loj refining thiab lub teeb hydrocarbon cov nroj tsuag yuav pib nyob rau hauv nruab nrab, thiab lub peev xwm ntau lawm yuav raug tso tawm nyob rau hauv 2021, thiab Tuam Tshoj tus PE ntau lawm yuav nce, tshwj xeeb tshaj yog HDPE ntau yam, nrog rau ntau cov kev pab cuam teem rau cov nroj tsuag tshiab thiab nce. kev lag luam kev sib tw 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.
