A concentration ratio yog tus piv ntawm kev sib koom ua lag luam sib koom ntawm ib lub tuam txhab muab rau tag nrho cov lag luam loj. Nws yog feem ntau xav txog 3-ruaj khov, 4-khov kho lossis 5-ruaj khov concentration piv . Concentration ratios yog siv rau ntsuam xyuas qhov twg rau lub khw muab yog oligopolistic.
Hauv txoj kev no, qhov siab concentration piv qhia dab tsi?
A high concentration piv qhia tias ob peb lub tuam txhab tsim tawm feem ntau ntawm kev lag luam tawm thiab tej zaum yuav qhia ib qho tseem ceeb ntawm lub zog ua lag luam hauv kev lag luam.
Kuj Paub, dab tsi yog 3 ruaj khov concentration piv? Txhais ntawm Concentration Ratios Qhov feem pua ntawm kev ua lag luam feem ntau coj los ntawm qhov loj tshaj plaws cov tuam txhab . Nws yuav yog ib qho 3 ruaj khov concentration piv (kev ua lag luam qhia tawm ntawm 3 biggest) los yog 5 ruaj khov piv . Qhov sib piv yog siv los txiav txim cov qauv kev lag luam thiab kev sib tw ntawm kev ua lag luam.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov plaub ruaj khov concentration piv ntsuas?
Cov plaub - ruaj khov piv yog feem ntau siv los qhia qib uas kev lag luam yog oligopolistic thiab qhov twg ntawm kev lag luam tswj tuav los ntawm lub plaub loj tshaj plaws cov tuam txhab hauv kev lag luam. Cov plaub - ruaj khov concentration ratio yog xam raws li kev lag luam feem ntawm qhov loj tshaj cov tuam txhab hauv kev lag luam.
Qhov siab Herfindahl Performance index txhais li cas?
Nce hauv Herfindahl Index feem ntau qhia kev txo qis hauv kev sib tw thiab nce kev ua lag luam lub zog, qhov txo qis qhia qhov rov qab. Xwb, yog siv tag nrho cov feem pua, cov qhov ntsuas yog li ntawm 0 txog 10,000 "points". Piv txwv li, ib qho qhov ntsuas ntawm 25 yog ib yam li 2,500 ntsiab lus.

Dab tsi yog qhov sib txawv ntawm kev lag luam thiab kev lag luam muaj teeb meem ntawm qhov ntsuas?
Kev Lag Luam thiab Kev Lag Luam ntawm Nplai. Economies of scale xa mus rau cov nqi txo rau ib chav tsev uas tshwm sim vim qhov nce ntawm tag nrho cov zis. Diseconomies ntawm scale, ntawm qhov tod tes, tshwm sim thaum cov zis nce mus rau qhov zoo tshaj plaws uas tus nqi ntawm ib chav pib nce
Dab tsi yog Kev Ntsuas Kev Ntsuas hauv kev tshaj tawm?
Lub ntsiab lus ntawm kev ntsuam xyuas lub tswv yim yog cov txheej txheem kom tau txais ib lub tswv yim ntsuam xyuas los ntawm koj lub hom phiaj cov neeg tuaj saib ua ntej nws yuav muaj rau pej xeem. Raws li qhov piv txwv, hais tias pawg neeg lag luam tuav ib hnub-ntev kev sib tham txog kev tawm tswv yim los tawm tswv yim rau kev tshaj tawm kev tshaj tawm

Risk Identification qhia koj tias qhov kev pheej hmoo yog dab tsi, thaum kev ntsuam xyuas kev pheej hmoo qhia koj tias qhov kev pheej hmoo yuav cuam tshuam li cas rau koj lub hom phiaj. Cov cuab yeej thiab cov txheej txheem siv los txheeb xyuas qhov pheej hmoo thiab ntsuas kev pheej hmoo tsis zoo ib yam
Dab tsi yog qhov tseem ceeb ntawm kev tswj torque hauv kev ntsuas ntsuas?
Kev tswj torque ua ob txoj haujlwm.Controlling torque nce nrog lub deflection ntawm lub txav system kom qhov kawg txoj hauj lwm ntawm tus taw tes rau ntawm qhov ntsuas yuav ua raws li qhov loj ntawm ib qho hluav taws xob ntau (piv txwv li tam sim no lossis voltage lossis lub zog) los ntsuas
