1. Qhov teeb meem ntawm kev lag luam

Copper yog ib qho tseem ceeb ntawm cov khoom siv raw, thiab nws txoj kev xav tau zoo txog kev lag luam. Raws li qhov kev lag luam loj tuaj, tooj liab nqi sawv raws li kev xav tau nce, thiab tooj liab nqi poob rau hauv kev txom nyem. Hauv kev ntsuam xyuas ntawm kev lag luam, muaj ob qho yeeb yam tseem ceeb heev, ib qho yog qhov kev loj hlob ntawm kev lag luam, los yog GDP ntawm kev loj hlob, lwm qhov yog qhov kev lag luam zus tuaj.

2. Kev Txawj Ntse thiab Kev Ncig Teb Chaws

Txoj cai tswjfwm import thiab export, tshwjxeeb raws li txoj cai tswjfwm, nws yog ib qho tseemceeb uas yuav tsum tau ua kom muaj txiaj ntsim rau lub tebchaw thiab kev xav tau los ntawm kev kho cov kev xa thiab kev xa tawm ntawm cov khoom muag los tswj cov kev xa thiab kev xa tawm ntawm cov khoom muag. Txij li thaum Lub Ib Hlis 1, 2008, Tuam Tshoj tau nqa cov nqi ntawm cov ntawv luam tawm ntawm cov roj refined copper, thiab cov nyiaj ua se tau ua dua rau kev ua kom muaj nuj nqes zoo dua 5%. 10% ntawm cov nyiaj ua se tau them rau cov khoom siv tooj liab (Nauv 79th ntawm 2007 ntawm General Administration of customs) tau raug txo.

3. Kev nthuav dav thiab kev hloov ntawm kev siv tooj liab

Kev siv yog qhov ncaj qha cuam tshuam rau tus nqi tooj, thiab kev lag luam ntawm tooj kev lag luam yog qhov tseem ceeb tshaj rau kev cuam tshuam kev noj haus. Nrog rau kev loj hlob sai ntawm science thiab technology, daim ntawv thov ntawm tooj tau txuas ntxiv, thiab tooj tau pib ua lub luag haujlwm ntawm kev siv tshuaj, biology, superconductivity thiab environmental protection. IBM tau txais tooj liab siv aluminium nyob rau hauv silicon chips, kos npe rau cov kev hloov tshiab nyob rau hauv daim ntawv thov ntawm tooj liab hauv semiconductor technology. Cov kev hloov no yuav cuam tshuam rau kev siv cov tooj liab hauv ntau qib.
