Kungekudala, ixabiso leemveliso zeekhemikhali liphakanyisiwe: Kukho iintlobo ezininzi kunye neentlobo ezinkulu. Ngo-Agasti, amaxabiso eemveliso zeekhemikhali aqalise ukunyuka. Phakathi kwamaxabiso eemveliso zemichiza angama-248 esiwalandeleyo, iimveliso ezili-165 zonyuka ngexabiso ngokunyuka komndilili wama-29.0%, kwaye ziimveliso ezingama-51 kuphela eziye zawa ngexabiso ngokuhla komndilili we-9.2%. Phakathi kwabo, amaxabiso e-MDI ecocekileyo, i-butadiene, i-PC, i-DMF, i-styrene kunye nezinye iimveliso ziye zaphakama ngokukhawuleza.

Imfuno yeemveliso zeekhemikhali idla ngokuba namaxesha amabini aphezulu, oko kukuthi ngoMatshi-Aprili emva koMthendeleko weNtwasahlobo kunye noSeptemba-Oktobha kwisiqingatha sesibini sonyaka. Idatha yembali ye-China Chemical Product Price Index (CCPI) ukusuka kwi-2012 ukuya kwi-2020 iphinda iqinisekise umthetho wokusebenza kweli shishini. Kwaye njengalo nyaka, amaxabiso emveliso aqhubekile nokunyuka ukususela ngo-Agasti, kwaye angena kunyaka wentshiseko engapheliyo ngoNovemba, kuphela i-2016 kunye ne-2017 eqhutywa yi-supply-side reforms.

Amaxabiso e-oyile ekrwada adlala indima ebalulekileyo ekubekweni kwamaxabiso emveliso yemichiza. Ngokubanzi, amaxabiso eemveliso zeekhemikhali aqhele ukunyuka kwaye ehle ngokuhambelana nokuguquguquka kwamaxabiso e-oyile ekrwada. Nangona kunjalo, kwinkqubo yokunyuka kwexabiso leemveliso zemichiza, amaxabiso e-oyile ekrwada ahlala eguquguquka, kwaye amaxabiso e-oyile ekrwada akhoyo asesezantsi kunamaxabiso ekuqaleni kuka-Agasti. Ukujonga emva kwiminyaka eyi-9 edlulileyo, ixabiso leemveliso zemichiza kunye ne-oyile ekrwada liye latenxa kakhulu kuphela izihlandlo ezi-5, ngokuqhelekileyo kwixesha eliphakamileyo okanye eliphantsi lomothuko, kwaye amaxabiso e-oyile ekrwada anyukile ngelixa amaxabiso eemveliso zemichiza ahlala ethe tyaba. okanye phantsi. Kuphela kulo nyaka ixabiso leemveliso zemichiza linyuka kakhulu, ngelixa ixabiso le-oyile ekrwada liguquguquka. Phantsi kweemeko ezinjalo, ukunyuka kwamaxabiso emveliso yemichiza kunyuse kakhulu iingeniso zeenkampani ezinxulumeneyo.

Iinkampani zemichiza zihlala zezinye zekhonkco kwikhonkco lemizi-mveliso, kwaye uninzi lwazo ezinyukayo okanye abathengi nazo ziinkampani zeekhemikhali. Ke ngoko, xa ixabiso lemveliso yeshishini A linyuka, ixabiso leshishini B, elishishini elisezantsi, nalo liya kunyuka. Ijongene nale meko, inkampani B mhlawumbi iyayinciphisa imveliso okanye inqumamise imveliso ukunciphisa ukuthenga, okanye inyuse ixabiso leemveliso zayo ukuze isuse uxinzelelo lokunyuka kweendleko. Ngoko ke, ingaba ixabiso leemveliso ezisezantsi zinokunyuka sisiseko esibalulekileyo sokugweba ukuzinza kokunyuka kwexabiso leemveliso zamachiza. Okwangoku, kumatyathanga amashishini amaninzi, ixabiso leemveliso zeekhemikhali sele liqalile ukusasazeka kakuhle.

Umzekelo, ixabiso le-bisphenol A linyusa ixabiso lePC, i-silicon metal iqhuba ixabiso le-silicon ephilayo, eqhuba ixabiso leekhompawundi zerabha kunye nezinye iimveliso, ixabiso le-adipic acid liqhuba ixabiso le-slurry kunye ne-PA66, kunye ixabiso le-MDI ecocekileyo kunye ne-PTMEG iqhuba ixabiso le-spandex.

Phakathi kwamaxabiso eemveliso zemichiza angama-248 esiwalandeleyo, amaxabiso eemveliso ali-116 ebesengaphantsi kwexabiso langaphambi kobhubhane; xa kuthelekiswa nexesha elifanayo kulo nyaka uphelileyo, amaxabiso emveliso ali-125 ebesezantsi kunexesha elifanayo kunyaka ophelileyo. Sisebenzisa ixabiso eliqhelekileyo leemveliso kwi-2016-2019 njengexabiso eliphakathi, kunye nexabiso lemveliso ye-140 lisekho ngaphantsi kwexabiso eliphakathi. Ngelo xesha, phakathi kweemveliso ze-54 zeekhemikhali ezisasazekayo esizilandeleyo, ukusasazeka kwe-21 kusekho ngaphantsi kokusasazeka ngaphambi kokuba ubhubhane; ukuba kuthelekiswa nexesha elifanayo kulo nyaka uphelileyo, ukusasazeka kwemveliso ye-22 kuphantsi kwexesha elifanayo kunyaka ophelileyo. Sisebenzisa i-2016-2019 i-avareji yemveliso yokusasazeka njengoko i-central spread, kunye ne-27 imveliso yokusabalalisa isekho ngaphantsi kokusabalalisa okuphakathi. Oku kuhambelana neziphumo zedatha ye-PPI yonyaka-ngonyaka kunye neziphumo zedatha ye-ring-on-kota.
