Laga bilaabo 2019 ilaa 2023, celceliska kobaca sanadlaha ah ee awoodda wax soo saarka PVC wuxuu ahaa 1.95%, awoodda wax soo saarkuna waxay ka korodhay 25.08 milyan oo tan sannadkii 2019 ilaa 27.92 milyan oo tan sannadkii 2023. Kahor 2021, ku tiirsanaanta soo dejinta waxay had iyo jeer ahayd qiyaastii 4%, inta badan waxaa ugu wacan qiimaha hooseeya ee ilaha dibadda iyo dhibka lagu qabo beddelka qaar ka mid ah alaabada heerka sare ah.

Saddexdii sano ee 2021-2023, awoodda wax soo saarka PVC ayaa korodhay, halka soo dejinta ay sidoo kale si degdeg ah u korodhay, sababtoo ah qaar ka mid ah aaladaha shisheeye waxaa saameeyay majeure xoog leh, sahaydu way saamaysay, qiimuhuna ma lahayn faa'iido tartan oo muuqata, ku tiirsanaanta soo dejintana waxay hoos ugu dhacday wax ka yar 2%. Isla mar ahaantaana, tan iyo 2021, suuqa dhoofinta PVC ee Shiinaha ayaa si degdeg ah u ballaartay, iyadoo faa'iidada qiimaha ay ka faa'iidaysanayso Hindiya, Koonfur-bari Aasiya iyo dalal kale, xaaladda dhoofinta PVC-na waxay saameyn sii kordheysa ku leedahay suuqa gudaha. Awoodda sii kordheysa ee walxaha ethylene waxay ka dhigan tahay qayb weyn, sidaas darteed waxay xoojinaysaa tartanka u dhexeeya alaabada kaarboon ee kalsiyum iyo wax soo saarka ethylene. Marka laga eego dhinaca 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.

Awoodda wax soo saarka sanadlaha ah ee 2023 iyadoo loo eegayo kala duwanaanshaha habka, inta badan waxay ku urursan yihiin shirkadaha kalsiyum carbide, oo ka dhigan 75.13% awoodda wax soo saarka qaranka, sababtoo ah Shiinuhu waa waddan leh dhuxul badan iyo saliid yar, dhuxushana waxaa inta badan lagu qaybiyaa gobolka waqooyi-galbeed, waqooyi-galbeed waxay ku tiirsan tahay dhuxul hodan ah, kheyraadka kaalshiyamka carbide ee kalsiyum, ganacsiyaduna inta badan waa xarumo taageero oo isku dhafan, sidaa darteed awoodda wax soo saarka PVC ee gobolka waqooyi-galbeed waa mid aad u weyn. Waqooyiga Shiinaha, Bariga Shiinaha, Koonfurta Shiinaha sannadihii ugu dambeeyay, awoodda cusub waxay inta badan tahay awoodda wax soo saarka ethylene, sababtoo ah gaadiidka xeebta, gaadiidka ku habboon, soo dejinta walxaha ceeriin iyo gaadiidka.

Marka laga eego dhinaca gobolka, gobolka waqooyi-galbeed ayaa wali kaalinta koowaad kaga jira 13.78 milyan oo tan oo awood wax soo saar ah. Sida laga soo xigtay isbeddellada gobolka, Koonfurta Shiinaha ayaa ku dartay 800,000 oo tan si ay u kabto farqiga baahida maxalliga ah, iyadoo arrintan lagu saleynayo, wareejinta kheyraadka Waqooyiga Shiinaha ee saamiga suuqa Koonfurta Shiinaha ayaa yaraaday, Waqooyiga Shiinaha ayaa ku daray oo keliya 400,000 oo tan oo qalab ah, gobollada kalena ma laha awood cusub. Guud ahaan, sanadka 2023, awoodda wax soo saarka ee Koonfurta Shiinaha, Waqooyiga Shiinaha iyo Waqooyi-galbeed Shiinaha oo keliya ayaa kordhi doonta, gaar ahaan Koonfurta Shiinaha, halkaas oo kororka awoodda wax soo saarku uu saameyn weyn ku leeyahay. Awoodda cusub ee sanadka 2024 waxay inta badan ku jiri doontaa Bariga Shiinaha.

2019-2023, awoodda warshadaha PVC ee Shiinaha ayaa sii fidaysa, taasoo ay keentay kororka sanadlaha ah ee wax soo saarka sannadihii u dambeeyay, awoodda wax soo saarka PVC ee gudaha ayaa sii fidaysa, 2019-2023 shan sano oo ballaarin ah oo ah 2.84 milyan oo tan.

Iyada oo ay ugu wacan tahay isbeddellada ku yimid ballaarinta awoodda dhexe ee Shiinaha iyo qaababka saadka iyo baahida dibadda, rarista badda iyo arrimo kale iyo tilmaamayaasha, soo dejinta Shiinaha ayaa si joogto ah hoos ugu dhacday, ku tiirsanaanta soo dejintana waxaa la filayaa inay hoos ugu dhacdo 1.74% sanadka 2023. Muddada dheer, iyadoo la kordhinayo sahayda gudaha, hagaajinta tayada badeecadaha, farqiga sahayda gudaha ee mustaqbalka ayaa si tartiib tartiib ah u yaraan doona.
