Cov kws tshaj lij tham txog Tuam Tshoj cov khoom siv hluav taws xob qis qis
Oct 25, 2022
Kev lag luam Concentration thiab Enterprise Economic Scale
Tsawg voltage hluav taws xob cov cuab yeej tsim khoom lag luam hauv Suav teb feem ntau yog tsom rau hauv Beijing, Tianjin, Liaoning, Shanghai, Jiangsu, Zhejiang thiab Guangdong, thiab kev faib khoom lag luam feem ntau tsim nyog. Muaj ntau qhov teeb meem hauv kev lag luam nyiaj txiag ntawm kev lag luam:
(1) Lub koom haum kev lag luam me me thiab tawg. Tsis muaj kev sib tw lub zog thiab qhov zoo. Tam sim no, muaj ob peb lub tuam txhab ntawm cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob hauv Suav teb uas tau nkag mus rau hauv lub teb chaws cov tuam txhab loj, thiab cov lag luam me thiab nruab nrab suav nrog ntau dua 90 feem pua (cov lag luam loj nrog cov nyiaj tau los muag txhua xyoo thiab tag nrho cov cuab tam ntawm 500 lab yuan. lossis ntau dua; cov lag luam nruab nrab nrog cov nyiaj tau los muag txhua xyoo ntawm 50 lab yuan lossis ntau dua; thiab cov lag luam me nrog cov nyiaj tau los muag txhua xyoo ntawm 50 lab yuan lossis ntau dua).
(2) Kev sib koom ua ke hauv cheeb tsam tsis cuam tshuam txog kev sib piv thiab cov txiaj ntsig kev sib koom tes. Hauv 20 xyoo txij li xyoo 1980s, cov khoom siv hluav taws xob qis qis tau nce los ntawm ntau dua 600 mus rau ntau dua 1000. Raws li qhov tsis pom kev mus rau cov haujlwm thiab cov khw muag khoom, muaj qhov tshwm sim loj ntawm kev lag luam hauv cheeb tsam convergence, qis. cov txiaj ntsig kev lag luam, qis qis dua kev tsim kho, ua rau cov khoom lag luam rov qab, pov tseg ntawm lub zog thiab cov khoom siv, thiab cov txiaj ntsig kev lag luam tsawg.
(3) Cov qauv kev ua haujlwm tsis tsim nyog, thiab cov khoom siv thev naus laus zis ntawm kev lag luam loj yog tsawg. Raws li kev txheeb cais, ntawm cov khoom siv tseem ceeb ntawm kev lag luam, tsuas yog 1/3 ntawm lawv tau ua haujlwm siab tshaj plaws thiab kev lag luam. Tsuas yog li ntawm 18 feem pua ntawm cov khoom lag luam ntawm cov tuam txhab tseem ceeb tau mus txog qib kev tshaj lij thoob ntiaj teb hauv xyoo 1990s.
Kev lag luam muag ntim qauv
Kev muag khoom ntawm cov khoom siv hluav taws xob qis hauv Suav teb feem ntau yog nyob hauv Suav teb, txhawb nqa cov khoom siv hluav taws xob, cov khoom siv tswj tsis siv neeg, thiab lwm yam. Raws li kev txheeb cais, rau txhua txhua 10000 kW ntawm cov khoom siv hluav taws xob tshiab, txog 40000 daim. ntawm ntau yam khoom siv hluav taws xob tsawg tsawg yuav tsum tau txhawb nqa, suav nrog txog 230 thav duab hom cua Circuit Court breakers thiab txog 2200 molded case Circuit Court breakers. Tsis tas li ntawd, qhov piv ntawm tag nrho cov peev txheej ntawm cov cuab yeej siv hluav taws xob tsawg thiab lub cev muaj zog yog li 0.5 pcs / W. Qhov ntawd yog hais tias, ib txheej ntawm 300000 kW cov khoom tsim hluav taws xob xav tau 1.2 lab daim ntawm ntau yam khoom siv hluav taws xob qis, suav nrog 6900 thav duab hom hluav taws xob qis hluav taws xob thiab 66000 molded case circuit breakers.
Cov khoom lag luam ntshuam thiab xa tawm qauv kev lag luam
Cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob tsis tuaj yeem nkag mus rau ntau hom thiab ntau, uas yog txwv los ntawm tsoomfwv cov cai. Feem ntau, tsuas yog cov khoom siv hluav taws xob tsawg tsawg uas yuav tsum tau muaj nyob rau hauv cov haujlwm tseem ceeb uas tsis tuaj yeem tsim tawm hauv tsev tuaj yeem raug txiav txim siab rau kev xa tawm, thiab lwm qhov, cov khoom lag luam ntawm lub tuam txhab txawv teb chaws loj yuav tsum raug xaiv raws li tus neeg ua lag luam txawv teb chaws.
Tus naj npawb ntawm cov khoom siv hluav taws xob uas tsis tshua muaj hluav taws xob xa tawm tsis loj thiab qhov nyiaj tsis siab
(1) Ua nrog cov ntaub ntawv txawv teb chaws thiab cov khoom xa tawm.
(2) Qhia tawm cov cuab yeej technology lossis khoom siv txawv teb chaws, thiab muag cov khoom rov qab rau lwm tus neeg sab nrauv -- kev them nyiaj ua lag luam.
Nyob rau hauv xyoo tas los no, Lub Xeev Kev Lag Luam thiab Kev Lag Luam Commission thiab Lub Xeev Machinery Industry Bureau tau tsim cov kev ntsuas los txhawb thiab txhawb kev xa tawm cov khoom siv tshuab thiab hluav taws xob. Xyoo 1999, Ministry of Foreign Trade thiab Economic Kev Koom Tes (MOFTEC) tau muab tso rau 9 lub tswv yim ntawm qhov teeb meem no, thiab cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob xa tawm hauv xyoo ntawd tau nce ntau.
