Iyo yegore rinobuda rinoramba riri pamatani zviuru gumi nezvisere. Mukuwedzera, muna 2021, iyo itsva yekugadzira mapoka emakambani kunze kwemakambani mana emakambani achange ari matani zviuru zvishanu. Nekuda kwekusanzwisisa kwekunzwisisa kwezvirongwa zvematare ese, zvinofungidzirwa pano kuti iyo itsva yekugadzira yekugadzira ichave iri matani zviuru zvishanu pagore kubva pa2022 kusvika 2025.
Maererano nekumhiri kwemakungwa ekugadzira, zvinofungidzirwa kuti mhirizhonga yePolysilic polysiction mu 2025 ichave ingangoita matani gumi nemakumi maviri nematanhatu, vachifungidzira kuti chiyero chekushandiswa kwemakungwa emakungwa echigadzirwa chiramba chisina kuchinjika. Mushure memutengo wePolysilicon wamuka zvakanyanya muna 2021, makambani eChinese akawedzera kugadzirwa uye kugadzirwa kwakawedzerwa. Mukupesana, makambani ekumhiri kwemakungwa ane hungwaru mukuronga kwavo kwemapurojekiti matsva. Izvi zvinodaro nekuti kutonga kwedunhu rePolysilicon indasitiri yatove mukutonga kweChina, uye kugadzirwa kwacho kuchiwedzera kuchiwedzera kunogona kuunza kurasikirwa. Kubva pane iyo mari yemutengo, simba rekushandisa ndiyo chikamu chikuru chemutengo wePolysilicon, saka mutengo wemagetsi wakakosha, uye Xinjiang, yemukati mongolia, Sichuan uye mamwe matunhu ane mikana iri pachena. Kubva pane chinodiwa side, seyakagadziriswa pasi pePolysilicon, China's silicon Wer yekugadzira maakaundi anopfuura 99% yehuwandu hwenyika. Iyo yekudzora indasitiri yePolysilicon inonyanya kuiswa muChina. Mutengo wePolysilicon zvakagadzirwa, mutengo wekufambisa wakaderera, uye kudiwa kwacho kwakavimbiswa zvizere. Kechipiri, China yakaisa mari yakakwirira yekurasa Iva ungwaru mukuvaka mapurojekiti matsva; Uyezve, mumakore achangopfuura, Chinese mhirizhonga poolysicon polysilics yekukudziridza nekuda kwemitero yemari, uyezve mune zvemari zvakakwanira kutsigira nekukurumidza uye kwakakura-kuwanda kwekuwedzera kwe kugadzirwa kwekugadzira.
Kubva pane kufanotaura kwePolysilicon kugadzirwa kuChina uye mhiri kwemakungwa kubva ku2022 kusvika 2025, kukosha kwekufungidzira kweGlobal Polysilicon kugadzirwa kunogona kupfupikiswa. Zvinofungidzirwa kuti iyo Global Polysilic kugadzirwa muna 2025 ichasvika pamamiriyoni zana emamiriyoni. Maererano nekumwe kufungidzira kwePolysilicon kugadzirwa, chikamu cheChina cheGlobal Proportonion inogona kuwanikwa. Zvinotarisirwa kuti mugove weChina unowedzera kuwedzera kubva pa2022 kusvika 2025, uye ichapfuura 87% muna 2025.
