Mu 2023, kukula kwakukulu kwamakampani a PC aku China kwatha, ndipo makampaniwa alowa m'dongosolo logaya zomwe zilipo kale. Chifukwa chakukula kwapakati pazida zopangira kumtunda, phindu la ma PC otsika lakula kwambiri, phindu lamakampani a PC lakwera kwambiri, komanso kuchuluka kwa magwiritsidwe ntchito ndi kutulutsa kwa mphamvu zopanga zapakhomo zakulanso kwambiri.

Mu 2023, kupanga ma PC apanyumba kunawonetsa kukwera kwa mwezi uliwonse, kokwera kwambiri kuposa mbiri yakale yanthawi yomweyo. Malinga ndi ziwerengero, kuyambira Januware mpaka Meyi 2023, kupanga okwana kwa PC ku China kunali pafupifupi matani 1.05 miliyoni, kuwonjezeka kwa 50% poyerekeza ndi nthawi yomweyi chaka chatha, ndipo kuchuluka kwa kugwiritsa ntchito mphamvu kumafika 68,27%. Mwa iwo, avareji yopanga kuyambira Marichi mpaka Meyi idaposa matani 200000, omwe amachulukitsa kawiri pachaka mu 2021.
1. Kukula kwapakati kwa mphamvu zapakhomo kwatha, ndipo mphamvu zatsopano zopangira zaka zisanu zikubwerazi ndizochepa.
Kuyambira 2018, mphamvu yaku China yopanga ma PC yakula kwambiri. Pofika kumapeto kwa 2022, mphamvu zonse zopanga ma PC zoweta zafika matani 3.2 miliyoni / chaka, kuchuluka kwa 266% poyerekeza ndi kumapeto kwa 2017, ndikukula kwapachaka kwa 30%. Mu 2023, China idzangowonjezera mphamvu zopanga ndi matani 160000 a Wanhua Chemical ndikuyambitsanso mphamvu yopangira matani 70000 pachaka ku Gansu, Hubei. Kuyambira 2024 mpaka 2027, makina atsopano opanga ma PC aku China akuyembekezeka kupitilira matani 1.3 miliyoni, ndikukula kochepa kwambiri kuposa kale. Chifukwa chake, m'zaka zisanu zikubwerazi, kugaya mphamvu zopangira zomwe zilipo, kuwongolera mosalekeza mtundu wazinthu, kupanga mosiyanasiyana, m'malo mwa zotumiza kunja, ndikuwonjezera kugulitsa kunja kudzakhala liwu lalikulu lamakampani aku China.
2. Zida zopangira zida zalowa m'nthawi yakukula kwapakati, zomwe zimapangitsa kuchepa kwakukulu kwa ndalama zamakampani komanso kuchepa kwapang'onopang'ono kwa phindu.

Malinga ndi kusintha kwa zinthu zopangira bisphenol A ndi mphamvu ziwiri zazikulu zopangira pansi pazaka zisanu zapitazi, kusiyana kwa kumtunda ndi kumtunda kwa mtsinje mu 2022 kunafika pamlingo wotsikitsitsa m'zaka zisanu, pa matani 1.93 miliyoni pachaka. Mu 2022, mphamvu yopanga bisphenol A, PC, ndi epoxy resin yomwe ikukula chaka ndi chaka ya 76.6%, 13.07%, ndi 16.56%, motsatana, inali yotsika kwambiri pamafakitale. Chifukwa chakukula komanso kupindula kwakukulu kwa bisphenol A, phindu lamakampani a PC lakula kwambiri mu 2023, kufika pamlingo wabwino kwambiri m'zaka zaposachedwa.

Kuchokera pakusintha kwa phindu kwa PC ndi bisphenol A m'zaka zitatu zapitazi, phindu lamakampani kuyambira 2021 mpaka 2022 limakhazikika kwambiri kumapeto. Ngakhale PC imakhalanso ndi phindu lalikulu, malire ake ndi otsika kwambiri kuposa a zipangizo; Mu Disembala 2022, zinthu zidasintha mwalamulo ndipo PC idasinthiratu zotayika kukhala phindu, kupitilira bisphenol A koyamba (1402 yuan ndi -125 yuan motsatana). Mu 2023, phindu la makampani a PC linapitirira kuposa bisphenol A. Kuyambira Januwale mpaka May, phindu lapakati pa awiriwa linali 1100 yuan/ton ndi -243 yuan/ton, motsatira. Komabe, chaka chino, kumtunda kwa zinthu zopangira phenol ketone kunalinso kutayika kwakukulu, ndipo PC idatembenuza zotayika.
M'zaka zisanu zikubwerazi, mphamvu yopanga ma ketoni a phenolic, bisphenol A, ndi epoxy resins idzapitiriza kukula kwambiri, ndipo PC ikuyembekezeka kupitiriza kukhala yopindulitsa ngati imodzi mwazinthu zochepa zomwe zimagwiritsidwa ntchito pamakampani.
3. Voliyumu yotumiza kunja yatsika kwambiri, pomwe zotumiza kunja zapanga zopambana.

Mu 2023, kuchuluka kwa ma PC apanyumba kudachepa kwambiri. Kuyambira Januwale mpaka Epulo, kuchuluka kwathunthu kwa PC yakunyumba kunali matani 358400, ndi kuchuluka kwa kunja kwa matani 126600 ndi voliyumu yotumiza matani 231800, kuchepa kwa matani 161200 kapena 41% poyerekeza ndi nthawi yomweyi chaka chatha. Chifukwa cha kuchotsedwa kwachangu / kosasunthika kwa zinthu zotumizidwa kunja ndi kukula kwa kunja kwa kunja, kusinthika kwa zipangizo zapakhomo pakati pa ogwiritsa ntchito kumtunda kwawonjezeka kwambiri, zomwe zalimbikitsanso kwambiri kukula kwa kupanga ma PC apakhomo chaka chino.
M'mwezi wa June, chifukwa chokonzekera mabizinesi awiri omwe amathandizidwa ndi ndalama zakunja, kupanga ma PC apanyumba mwina kudachepa poyerekeza ndi Meyi; Mu theka lachiwiri la chaka, zopangira zopangira kumtunda zinapitirizabe kukhudzidwa ndi kuwonjezereka kwa mphamvu, zomwe zimapangitsa kuti zikhale zovuta kupititsa patsogolo phindu, pamene PC yotsika ikupitirizabe kupanga phindu. Potengera izi, phindu lokhazikika lamakampani a PC likuyembekezeka kupitiliza. Kupatula mafakitale akuluakulu a PC omwe adakhazikitsabe mapulani okonzekera kuyambira Ogasiti mpaka Seputembala, zomwe zidzakhudza kupanga mwezi uliwonse, kugwiritsa ntchito mphamvu zapakhomo ndi kupanga zizikhalabe pamlingo wapamwamba kwambiri kwa nthawi yotsalayo. Chifukwa chake, zikuyembekezeredwa kuti kupanga kwapakhomo kwa PC mu theka lachiwiri la chaka kupitilira kukula poyerekeza ndi theka loyamba.
