Laga soo bilaabo 2019 ilaa 2023, celceliska heerka kobaca sanadlaha ah ee awoodda wax soo saarka PVC wuxuu ahaa 1.95%, awoodda wax soo saarkuna waxay ka korodhay 25.08 milyan tan 2019 ilaa 27.92 milyan tan 2023. Kahor 2021, ku tiirsanaanta soo dejinta had iyo jeer waxay ahayd agagaarka 4%, inta badan. iyadoo ay ugu wacan tahay qiimaha jaban ee ilaha ajnabiga ah iyo dhibka ah in la bedelo qaar ka mid ah alaabooyinka heerka sare ah.

Saddexdii sano ee 2021-2023, awoodda wax-soo-saarka PVC ayaa kor u kacday, halka soo dejinta ay sidoo kale si degdeg ah u korodhay, sababtoo ah qaar ka mid ah qalabyada ajnabiga ah waxaa saameeyay xoogga majeure, saadka ayaa saameeyay, qiimihiisuna ma lahayn faa'iido tartan oo muuqda, ku tiirsanaanta soo dejinta ayaa hoos u dhacday. in ka yar 2%. Isla mar ahaantaana, tan iyo 2021, suuqa dhoofinta PVC ee Shiinaha ayaa si xawli ah u kordhay, faa'iidada qiimaha, waxaa doorbiday Hindiya, Koonfur-bari Aasiya iyo dalal kale, iyo xaaladda dhoofinta PVC waxay leedahay saameyn sii kordheysa ee suuqa gudaha. Awoodda si degdega ah u kordheysa ee walxaha ethylene waxay ku xisaabtamaysaa qayb weyn, sidaas awgeed waxay xoojinaysaa tartanka ka dhexeeya kaalshiyam carbide iyo alaabta habka ethylene. Marka loo eego qaybinta gobolka ee awoodda wax-soo-saarka cusub, awoodda wax-soo-saarka cusub ee 2023 waxay inta badan ku urursan tahay Shandong iyo Koonfurta Shiinaha.

2023 awoodda wax-soo-saarka sanadlaha ah iyadoo loo eegayo kala duwanaanshaha geeddi-socodka, inta badan waxay ku urursan yihiin shirkadaha kaalshiyam carbide, oo lagu xisaabtamayo 75.13% awoodda wax-soo-saarka qaranka, sababtoo ah Shiinaha waa waddan leh dhuxul badan iyo saliid yar, dhuxusha inta badan waxaa lagu qaybiyaa gobolka waqooyi-galbeed, waqooyi-galbeed waxay ku tiirsan tahay dhuxusha hodanka ah, kheyraadka kaarbiid ee kaalshiyamka, iyo ganacsiyadu inta badan waa tas-hiilaad taageero oo isku dhafan, sidaas darteed awoodda wax-soo-saarka PVC ee gobolka waqooyi-galbeed waa mid aad u ballaaran. Waqooyiga Shiinaha, Shiinaha Bari, Koonfurta Shiinaha sannadihii la soo dhaafay, awoodda cusub ayaa inta badan ah awoodda wax soo saarka ethylene, sababtoo ah xeebta, gaadiidka ku habboon, soo dejinta alaabta ceeriin iyo gaadiidka.

Marka loo eego dhinaca gobolka, gobolka waqooyi-galbeed ayaa weli ku jira kaalinta koowaad oo leh 13.78 milyan oo tan oo awood wax-soo-saar ah. Marka loo eego isbeddelada gobolka, Koonfurta Shiinaha waxay ku dartay 800,000 oo tan si ay u kabto farqiga baahida maxalliga ah, taas oo ku saleysan, wareejinta kheyraadka Waqooyiga Shiinaha ee saamiga suuqa Koonfurta Shiinaha ayaa yaraaday, Waqooyiga Shiinaha ayaa kaliya ku daray 400,000 tan oo qalab ah, iyo gobollo kale. ma laha awood cusub. Guud ahaan, 2023, kaliya Koonfurta Shiinaha, Waqooyiga Shiinaha iyo Waqooyi-galbeed ee Shiinaha awoodda wax-soo-saarka ayaa kordhin doona, gaar ahaan Koonfurta Shiinaha, halkaasoo kororka awoodda wax-soo-saarka ay saameyn weyn ku leedahay. Awoodda cusub ee 2024 waxay inta badan ahaan doontaa Bariga Shiinaha.

2019-2023, Shiinaha ee awoodda warshadaha PVC sii waday in ay ballaariso, kexeeyey kororka sanadlaha ah ee wax soo saarka sannadihii la soo dhaafay, awoodda wax soo saarka PVC gudaha ayaa sii waday in la ballaariyo, 2019-2023 shan sano oo ballaarinta awoodda 2.84 milyan oo tan.

Sababo la xiriira isbeddelada ku yimid ballaarinta awoodda dhexe ee Shiinaha iyo qaababka saadka iyo dalabaadka dibadda, xamuulka badda iyo arrimo kale iyo tilmaamayaasha, soo dejinta Shiinaha ayaa si joogto ah hoos ugu dhacay, ku tiirsanaanta soo dejinta ayaa la filayaa inay hoos ugu dhacdo 1.74% sanadka 2023. Mustaqbalka fog, iyadoo kororka saadka gudaha, tayaynta tayada wax soo saarka, farqiga saadka gudaha ee mustaqbalka waa inuu si tartiib tartiib ah u yaraado.
