Qhov tob hauv kev tsom xam ntawm kev lag luam iav fiber ntau
Txheej txheem txheej txheem ntawm lub tank ncu yog qhov tseem ceeb ntau lawm txheej txheem ntawm cov iav fiber. Txij li qhov pom ntawm tus nqi, kev tswj ntawm cov khoom siv sab saum toj thiab lub zog tuaj yeem txo tus nqi ntawm cov khoom siv raw, qhov degree ntawm automation ntawm cov kab ntau lawm tuaj yeem txhim kho kev ua tau zoo, txo tus nqi ua haujlwm, thiab cov nplai ntawm cov peev xwm tsim tawm tuaj yeem txo tus nqi txo nqi hauv chav. Cov khoom lag luam thiab cov khoom siv cov khoom lag luam nyob hauv nruab nrab thiab qis dua yog los ntawm lub teeb pom kev lag luam, muaj ntau yam khoom lag luam thiab kev siv tshiab, kev lag luam yuav tsum nce R& D kev nqis peev thiab tswj cov nyiaj tau los siab dhau los ntawm cov kev qhia txuas ntxiv ntawm cov khoom tshiab.
Kev lag luam txwv tsis pub nkag, kev muaj peev xwm tshiab kev loj hlob qeeb
Iav fiber ntau kev lag luam nkag pib lub siab, Qhov kev lag luam siab siab, Lub ntiaj teb' s sab saum toj tsib lub tuam txhab ua lag luam rau 64% ntawm lub peev xwm, Tuam Tshoj' s saum toj kawg nkaus rau kev lag luam suav 80% ntawm lub peev xwm. Xyoo 2018 yog ib xyoo ntawm kev tsim cov iav fiber ntau, Kev tsim kev lag luam iav fiber ntau hauv kev loj hlob 15% / 13% xyoo 2018/2019, ua rau muaj kev cuam tshuam. Iav fiber ntau lub peev xwm kev loj hlob yuav poob rau yav tom ntej, Kev muaj peev xwm ntau lawm tau cia siab tias 7.5% -3.3% nyob rau xyoo 2020/2021. Kev xa tawm ntau, Tos rau kev rov qab los ntawm kev xa tawm txawv teb chaws thov rov qab cov iav fiber ntau daim ntaub ntawv muaj dav, Ua kom pom tseeb rau kev tsim kho thiab tsheb thauj mus los, Cuam tshuam los ntawm macroeconomics, Ntiaj teb iav fiber ntau qhov kev thov tau nce txog 1.6 npaug ntawm GDP. Cuam tshuam los ntawm kev cuam tshuam txawv tebchaw nyob rau xyoo 2020, Kev lag luam iav fiber ntau xa khoom thaiv, Ntiaj teb iav fiber ntau qhov kev thov yuav tsum tau nce ntawm -8.3 rau 6.7 ib xees los ntawm 2020/2021, Tuam Tshoj' s iav fiber ntau xav tau kev loj hlob ntawm 1.6% / 11 %, Iav fiber ntau qhov kev thov yuav tsum txhim kho nyob rau hauv 2021.
Kev muab elasticity tsis muaj zog, cov nqi poob ze rau qhov nqi
Tom qab cov kab ntau lawm ntawm cov iav fiber tau qhib, nws xav tau 8-10 xyoo kev tsim tawm tas mus li, thiab nws nyuaj rau kev txo cov load tswj kev ua haujlwm ib nrab, yog li cov mov elasticity ntawm iav fiber yog tsis muaj zog. Thaum qhov kev thov zoo dua, vim tias cov khoom siv nruj heev, tus nqi nce siab elasticity yog loj; thaum qhov kev thov poob, qhov cub tsis tuaj yeem txwv kev tsim khoom, uas ua rau cov khoom lag luam nce ntxiv, thaum cov lus nug nce ntxiv rau qee yam, yuav muaj kev txo tus nqi nce mus rau cov lus nug. Tam sim no, tus nqi ntawm ntxhib zeb tau poob ze ntawm tus nqi kab ntawm qee cov lag luam, thiab qhov poob qis ntxiv yuav ua rau qee lub lag luam kaw lawv cov peev txheej ntau lawm thiab ncav cuag cov kev sib cog lus.
Tus nqi yog rau hauv qab ntawm lub voj voog thiab kev tso tawm elastic tom qab kev teeb tsa ua kom zoo dua
Vim tias kev kis mob txawv teb chaws tsis dhau, qee cov kab tsim tawm tshiab yuav muab tso rau hauv kev tsim tawm hauv 3-4 lub hlis xyoo 2020, qhov muab khoom siv thiab xav tau ntawm kev lag luam muaj kev hloov nyuaj heev, thiab tus nqi rov yuav tseem hover hauv qab Cov. Kev tsim iav fiber ntau hauv kev lag luam yuav tsum tau txiav txim siab txog 3.3% nyob rau xyoo 2021, xav tau kev nce ntawm 11%, kev lag luam cov qauv yuav tsum txhim kho, iav fiber ntau cov nqi yuav nce siab. Vim tias qhov kev lag luam nkag mus rau qhov siab yog qhov siab, thiab kev lag luam tsom qib siab tau siab, cov thawj coj kev koom tes kev cia siab nyob rau hauv qhov kev thov xav tau muaj zog, cov iav fiber nqe elasticity nce ntxiv, xav zoo dua tom qab phaum teeb meem txhim kho lub iav fiber nqi kev sib.
