Nyob rau hauv 2017, lub tsev kawm ntawv tau ua ntau tshaj 50 feem pua ntawm lub ntiaj teb lub PCB kev tsim tawm, thiab PCB cov khoom poob rau hauv Teb Chaws Asmeskas cov se sau, thiab tariff ntau ntawm 2% mus rau 27%. Nyob rau hauv cov nqe lus ntawm lub industrial muaj, peb tau ua ib co tsom xam thiab reference:
Tom qab ob peb twist thiab hloov hauv Sino-Teb Chaws Asmeskas kev ua tsov ua rog, muaj ib qho ploj mus ntxiv: Sino-Teb Chaws Asmeskas kev tsov rog pib txij thaum lub Peb Hlis 8, thiab tom qab ntau ntau qhov kev sib khom, tsis muaj kev pom zoo. Thaum kawg, lub Rau Hli 15, Tebchaws Meskas tau sau ib daim ntawv qhia tias nws yuav ua kom 25% ntawm tus nqi ntawm 1,102 cov khoom siv nrog tus nqi tag nrho ntawm $ 50 billion. Lub neej yav tom ntej ntawm kev ua tsov ua rog ua lag luam yog tsis muaj kev txwv thiab muaj ib qho ploj mus ntxiv. Yawg Japanese-Teb Chaws Asmeskas ua lag luam kev lag luam yog kev siv, thiab kev lag luam ua lag luam yog qhov nyuaj hloov cov kev lag luam: Japanese-American kev ua tsov ua rog tau kav ntev txog 30 xyoo. Sib koom hauv kev lag luam los ntawm textiles, hlau rau xim TV, tsheb thauj khoom thiab tshuab luam yeeb. Nqa tau lub tsheb yam khoom ua kev piv txwv. Nyob rau hauv 12 xyoo tom qab Tsoomfwv Meskas tau tswm 100% tariff ntawm $ 5.99 npaug ntawm qhov khoom lag luam khoom noj khoom haus tsawg tshaj plaws nyob rau hauv 1995, Japanese pib kev lag luam tau pib muaj kev loj hlob sai ntawm ntau tshaj 8%. Txoj kev lag luam tsis tau muab coj mus ua lag luam. Thiab nres nce.
PCB peev yuav tsiv mus rau Tuam Tshoj, tau siv 5G rau plaub xyoos tom ntej thiab kev loj hlob thoob ntiaj teb ntawm cov hluav taws xob hluav taws xob yuav nce mus rau 1.94%: Txij xyoo 2008 txog 2017, lub ntiaj teb feem coob ntawm PCB cov zis hauv Suav teb yuav nce, nce ntawm 31.11% ntawm 2008 mus rau 2017. 50.82%, tus nqi tso tawm ntawm Tuam Tshoj tus PCB kev lag luam nce ntawm US $ 15.037 nais mus rau US $ 28.093 billion, nrog ib tug compound txhua xyoo kev loj hlob ntawm 6.45%, deb tshaj li thoob ntiaj teb kev loj hlob ntawm 1.35%. Hauv plaub lub xyoos tom ntej, tau txais txiaj ntsim los ntawm kev tsim kho ntawm 5G cov chaw ua noj thiab qhov nce ntawm kev xav tau tsheb hluav taws xob, lub ntiaj teb kev lag luam compound growth nce yuav nce mus rau 1.94%.
Tag nrho PCB kev lag luam muaj kev txwv rau kev ua tsov ua rog. Nyob rau hauv ntau zaus, nws cuam tshuam tsawg dua 3%. Nyob rau hauv xyoo tas los, Tuam Tshoj txoj kev xa khoom ntawm PCBs mus rau Tebchaws Meskas tau nyob ib ncig ntawm US $ 600 lab. Raws li Tuam Tshoj tus PCB cov zis tau hlob zuj zus, nws tau txheeb xyuas teb chaws Asmeskas PCB. Nyob rau hauv xyoo ntawd, qhov kev faib ua feem ntawm Tuam Tshoj tus PCB tso tawm tus nqi qis. Tuam Tshoj kev luam tawm ntawm PCB kev lag luam rau Tebchaws Meskas tau tshaj tawm rau qhov feem ntau ntawm Tuam Tshoj tus PCB xa tuaj rau xyoo ntawd, txij li 5.01% ntawm xyoo 2008 mus rau 6.39% hauv xyoo 2016, tab sis nws tsuas tshuav 3%
