Muva nje, intengo yemikhiqizo yamakhemikhali ikhuphukile: Kunezinhlobo eziningi nezinhlobonhlobo ezinkulu. Ngo-Agasti, izintengo zemikhiqizo yamakhemikhali seziqalile ukukhuphuka. Phakathi kwamanani entengo emikhiqizo yamakhemikhali angama-248 esiwalandele, imikhiqizo engu-165 inyuke intengo ngokunyuka okumaphakathi okungama-29.0%, futhi yimikhiqizo engama-51 kuphela eyehle intengo ngesilinganiso sokwehla ngo-9.2%. Phakathi kwazo, amanani entengo ye-MDI ehlanzekile, i-butadiene, i-PC, i-DMF, i-styrene neminye imikhiqizo ikhuphuke kakhulu.

Isidingo semikhiqizo yamakhemikhali ngokuvamile sinezinkathi ezimbili eziphezulu, okungukuthi ngoMashi-Ephreli ngemva koMkhosi Wasentwasahlobo kanye noSepthemba-Okthoba engxenyeni yesibili yonyaka. Idatha yomlando ye-China Chemical Product Price Index (CCPI) kusukela ngo-2012 kuya ku-2020 nayo iqinisekisa umthetho wokusebenza kwalo mkhakha. Futhi njengalo nyaka, amanani entengo aqhubekile nokukhuphuka kusukela ngo-Agasti, futhi angena onyakeni wentshiseko enganqamuki ngoNovemba, kuphela u-2016 no-2017 oqhutshwa ukuguqulwa kwe-supply-side.

Amanani kawoyela ongahluziwe adlala indima ebalulekile ekubekweni kwentengo kwemikhiqizo yamakhemikhali. Ngokuvamile, amanani entengo yemikhiqizo yamakhemikhali ngokuvamile ayakhuphuka futhi ehle ngokuhambisana nokushintshashintsha kwamanani kawoyela ongahluziwe. Kodwa-ke, ohlelweni lokwenyuka kwentengo yemikhiqizo yamakhemikhali, amanani kawoyela ongahluziwe ngokuyisisekelo ahlala eguquguquka, futhi amanani amanje kawoyela ongahluziwe asephansi kunawasekuqaleni kuka-Agasti. Uma sibheka emuva eminyakeni eyi-9 edlule, intengo yemikhiqizo yamakhemikhali kanye nowoyela ongahluziwe ichezuke kakhulu izikhathi ezi-5 kuphela, imvamisa ngesikhathi sokushaqeka okuphezulu noma okuphansi, futhi amanani kawoyela ongahluziwe akhuphukile ngenkathi amanani emikhiqizo yamakhemikhali ehlala ephansi. noma phansi. Kulo nyaka kuphela lapho intengo yemikhiqizo yamakhemikhali ikhuphuka kakhulu, kuyilapho intengo kawoyela ongahluziwe ishintshashintsha. Ngaphansi kwezimo ezinjalo, ukukhuphuka kwamanani entengo yemikhiqizo yamakhemikhali kukhulise kakhulu inzuzo yezinkampani ezihlobene.

Izinkampani zamakhemikhali ngokuvamile zingenye yezixhumanisi zochungechunge lwezimboni, futhi iningi lazo ezikhuphuka nomfula noma amakhasimende nazo ziyizinkampani zamakhemikhali. Ngakho-ke, lapho intengo yomkhiqizo webhizinisi A ikhuphuka, izindleko zebhizinisi B, okuyibhizinisi eliphansi, nazo zizokhuphuka. Ibhekene nalesi simo, inkampani B inciphisa ukukhiqizwa noma imise ukukhiqiza ukuze yehlise ukuthenga, noma inyuse intengo yemikhiqizo yayo ukuze isuse ingcindezi yezindleko ezikhuphukayo. Ngakho-ke, ukuthi intengo yemikhiqizo engaphansi ingakhuphuka yini kuyisisekelo esibalulekile sokwahlulela ukusimama kokukhuphuka kwentengo yemikhiqizo yamakhemikhali. Njengamanje, emaketangeni amaningi ezimboni, intengo yemikhiqizo yamakhemikhali isiqalile ukusabalala ngokushelela.

Isibonelo, intengo ye-bisphenol A inyusa intengo ye-PC, i-silicon metal ishayela inani le-silicon ephilayo, eshayela intengo yezinhlanganisela zenjoloba neminye imikhiqizo, intengo ye-adipic acid ishayela intengo ye-slurry ne-PA66, kanye intengo ye-MDI emsulwa kanye ne-PTMEG ishayela intengo ye-spandex.

Phakathi kwamanani entengo yemikhiqizo yamakhemikhali angama-248 esiwalandele, amanani entengo yemikhiqizo ayi-116 ayesaphansi kunentengo yangaphambi kwalolu bhubhane; uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule, amanani entengo yemikhiqizo ayi-125 ayephansi kunesikhathi esifanayo ngonyaka odlule. Sisebenzisa intengo emaphakathi yemikhiqizo ngo-2016-2019 njengentengo emaphakathi, futhi izintengo zemikhiqizo eziyi-140 zisephansi kunentengo emaphakathi. Ngesikhathi esifanayo, phakathi kokusabalala komkhiqizo wamakhemikhali we-54 esikulandele, ukusabalala kwe-21 kusephansi kunokusabalala ngaphambi kwalolu bhubhane; uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule, ukusabalala kwemikhiqizo engama-22 kuphansi kunesikhathi esifanayo ngonyaka odlule. Sisebenzisa isilinganiso sika-2016-2019 sokusabalala komkhiqizo njengokusabalala okumaphakathi, futhi ukusabalala kwemikhiqizo engama-27 kusephansi kunokusabalala okumaphakathi. Lokhu kuhambisana nemiphumela yedatha ye-PPI yonyaka nonyaka kanye ne-ring-on-quarter data.
