Kubva 2019 kusvika 2023, avhareji yegore yekukura kwePVC kugadzirwa kwehuwandu hwaive 1.95%, uye huwandu hwekugadzira hwakakwira kubva pa25.08 miriyoni matani muna2019 kusvika 27.92 miriyoni matani muna 2023. nekuda kwemutengo wakaderera wezvinyorwa zvekunze uye kuoma kwekutsiva zvimwe zvigadzirwa zvepamusoro.

Mukati memakore matatu e2021-2023, kugadzirwa kwePVC kwakawedzera, ukuwo kutengwa kunze kwenyika kwakawedzera nekukurumidza, nekuti mamwe maturusi ekunze akakanganiswa neforce majeure, kupihwa kwakakanganiswa, uye mutengo waive usina mukana wekukwikwidza, uye kutsamira kwekunze kwakadonha kusvika. isingasviki 2%. Panguva imwecheteyo, kubvira 2021, musika wekuChina wePVC wekutengesa kunze wakawedzera nekukurumidza, uye pasi pemubhadharo wemutengo, wakafarirwa neIndia, Southeast Asia nedzimwe nyika, uye mamiriro ekunze ePVC anowedzera kuwedzera pamusika wepamba. Iyo inokurumidza kuwedzera kugona kweiyo ethylene zvinhu inoverengera chikamu chikuru, nekudaro ichiwedzera kukwikwidza pakati pe calcium carbide uye ethylene process zvigadzirwa. Kubva pamaonero ekugoverwa kwedunhu kwehutsva hutsva hwekugadzira, huwandu hutsva hwekugadzira muna 2023 hunonyanya kutariswa muShandong neSouth China.

2023 gore rega rega rekugadzira huwandu maererano nekusiyaniswa kwemaitiro, kunyanya yakatarisana mumabhizinesi e calcium carbide, inoverengera 75.13% yehuwandu hwekugadzira nyika, nekuti China inyika ine marasha akawanda uye mashoma mafuta, uye marasha anonyanya kugoverwa kuchamhembe kwakadziva kumadokero, iyo kuchamhembe kwakadziva kumadokero kunovimba nemarasha akapfuma, calcium carbide zviwanikwa, uye mabhizinesi anonyanya kubatanidzwa anotsigira zvivakwa, saka iyo PVC kugadzirwa kwenzvimbo mudunhu rekuchamhembe kwakadziva kumadokero kwakakura. Maodzanyemba China, East China, Maodzanyemba China mumakore achangopfuura, hunyanzvi hutsva hunonyanya kusimba ethylene yekugadzira, nekuda kwemahombekombe, kufambisa kuri nyore, kupinza zvinhu mbishi uye kutakura.

Kubva pamaonero edunhu, dunhu rekuchamhembe kwakadziva kumadokero richiri kutanga ne13.78 miriyoni matani ekugadzira. Zvinoenderana nekuchinja kwedunhu, South China yakawedzera 800,000 matani kuti iwedzere kudiwa kwenzvimbo gap, nechikonzero ichi, kutamiswa kwezviwanikwa muNorth China kuenda kuSouth China kumusika wemusika kwakaderedzwa, North China yakangowedzera seti ye400,000 matani emidziyo, uye mamwe matunhu. havana simba idzva. Pakazara, muna 2023, chete South China, North China uye Northwest China kugona kwekugadzira kuchawedzera, kunyanya muSouth China, uko kuwedzera kwehuwandu hwekugadzira kune simba guru. Hunhu hutsva muna 2024 huchanyanya kuve muEast China.

2019-2023, China yePVC indasitiri indasitiri yakaramba ichiwedzera, ichifambiswa nekuwedzera kwegore kwekugadzirwa mumakore achangopfuura, mudzimba PVC kugadzirwa kwesimba rakaramba richiwedzera, 2019-2023 makore mashanu ekuwedzera kugona kwematani 2.84 miriyoni.

Nekuda kwekuchinja kwekuwedzera kwekuwedzera kweChina uye kupa mhiri kwemakungwa uye kudiwa kwemaitiro, kutakura zvinhu mugungwa nezvimwe zvinhu uye zviratidzo, kutengeswa kweChina kwakaramba kuchiramba, uye kutsamira kwekunze kunotarisirwa kudonha kusvika 1.74% muna 2023. Mukufamba kwenguva, neiyo kuwedzera kwekupa mudzimba, chigadzirwa chemhando yepamusoro, iro remangwana rekupa mudzimba gap rinosungirwa kudzikira zvishoma nezvishoma.
