Lub coefficient ntawm elasticity ntawm kev thov

Mov thiab thov muaj lub peev xwm hloov mus hloov kev ua lag luam tej yam kev mob, hu ua elasticity. Niaj hnub no, yuav luag tsis muaj ib tug seem ntawm lub kev khwv nyiaj txiag yuav tsis tau tsis muaj tswvyim no: lub hom phiaj ntawm lub ruaj, tus tsom xam cov mov thiab thov, economic mus, economic kev ntshaw, Eri, etc.

kev ua lag luam rhiab heev rau cov no thiab lwm yam, ua lag luam tej yam kev mob yus muaj los ntawm ib tug tshwj xeeb coefficient ntawm elasticity ntawm kev thov. Lub ntsiab lus ntawm no parameter yog lub nram qab no: yuav ua li cas yamntxwv tus nqi ntawm cov kev thov hloov thaum ua lag luam zoo tshaj kev hloov los ntawm 1%.

Nyob rau hauv lub chav tsev xaiv, lub peev xwm los teb rau ib qho ntawm cov nyiaj txiag ntau yam rau cov kev hloov nyob rau hauv lub taw qhia los ntawm ib tug ntau yam ntawm txoj kev. Yog li ntawd, los koom ua cov kev xaiv, siv qhov feem pua txoj kev ntsuas.

Lub coefficient ntawm elasticity ntawm kev thov yog xam rau lub hauv paus ntawm ob txoj kev:

- arc elasticity (elasticity ntawm lub arc), rau cov uas nws yog tsim nyog los paub qhov pib thiab tom ntej theem ntawm tus nqi thiab tagnrho;

- chaw elasticity (elasticity nyob rau hauv lub taw tes) nrog ib tug predetermined muaj nuj nqi ntawm kev thov thiab tus nqi ntau ntau thiab lub hauv paus tseem ceeb thov.

Hom ntawm elasticity ntawm kev thov yog yog txhais nqe, nyiaj tau los, thiab tej zaum nws yuav tsum yog ib tug ntoo khaub lig ntawm lub ob khoom.

Lub coefficient ntawm elasticity ntawm kev thov rau cov uas tsis qhia yuav ua li cas quantitatively hloov thov thaum nws tsub kom los yog txo los ntawm 1%. Nws yog ua tau kom tsim nyog hauv qab no rau yooj:

- inelastic thov - yog yus muaj los ntawm ib tug qeeb qeeb pace ntawm kev loj hlob ntawm muas ntau ntawm cov khoom tshaj tus nqi uas yuav txo tau ntawm nqe;

- elastic thov - yog yus nyob rau hauv uas cov yuav txo tau cov nqi ntawm 1% thov nce ntau tshaj li 1%;

- ib tug tsev elasticity - yog tsiag ntawv los ntawm tib tus nqi ntawm txoj kev loj hlob ntawm muas khoom thiab tus naj npawb ntawm fallers.

Lub coefficient ntawm cov nyiaj khwv tau elasticity ntawm kev thov qhia yuav ua li cas thov hloov quantitatively, thaum cov nyiaj tau los yuav tsum tsawg dua / dua los ntawm 1%.

Yog hais tias qhov no daim duab yog tsis zoo, ces nws yog feem ntau yuav qhia txog qhov uas tsis muaj zoo tshaj ntawm cov khoom muag, vim hais tias nyiaj khwv tau los nce, thiab qhov kev thov rau cov khoom uas txo.

Nrog nws zoo nqi ntawm cov khoom yuav suav hais tias ib txwm, thiab:

- yog hais tias tus nqi yog tsis tshua muaj me me, tsawg tshaj li 1, piv txwv li, qhov kev thov rau tej yam khoom loj hlob qeeb qeeb nyiaj khwv tau los, ces peb yuav tau tham, feem ntau yuav nyob rau hauv tus yam;

- yog hais tias tus nqi ntawm cov index ntau, nws yog xam qhovkev nyob rau hauv cov khoom kim heev cov khoom, nyiaj khwv tau los txoj kev loj hlob lags qab thov rau cov khoom.

Lub coefficient ntawm tus ntoo khaub lig-elasticity ntawm kev thov qhia qhov kev hloov nyob rau hauv kev thov rau ib co cov khoom Thiab yog hais tias tus nqi ntawm cov khoom nyob rau hauv cov kev hloov los ntawm 1%. Nws yuav ua tau zoo, tsis zoo thiab pes tsawg.

- Zoo qhov tseem ceeb ntawm cov coefficient ntawm elasticity yog hloov cov khoom (interchangeable), uas lwv nyob rau hauv kev ua lag luam, piv txwv li, butter thiab margarine. Nrog ib qho kev nce rau hauv tus nqi ntawm margarine yog ib tug loj hlob coob rau roj, vim hais tias nws tau ua cheaper nyob rau hauv kev sib raug zoo rau tus tshiab muaj zog nqi ntawm margarine. Thiab qhov ntau interchangeable ob pab, ntau dua tus nqi ntawm qhov ntsuas no.

- Tsis zoo qhov tseem ceeb ntawm no coefficient yog attendant kev pab cuam (complementary), lawv yog siv ua ke. Piv txwv li, yog hais tias peb xav txog cov khau thiab kho mob khoom, ces nrog ib qho kev nce nyob rau hauv kev thov rau khau nqi txo los ntawm cov txhais tau tias, uas yog hais tias qhov kev nce rau hauv tus nqi ntawm ib co cov khoom yog cov uas muaj nws ib tug yuav txo tau nyob rau hauv lub noj ntawm lwm tus, thiab qhov ntau lawv complementarity, li ntawd, yuav muaj ntau tsis coefficient.

- Ib tug pes tsawg tus nqi ntawm qhov ntsuas regards elasticity kev pab cuam uas tsis interchangeable los yog complementary, i.e. nyob rau hauv cov ntaub ntawv no, tsis pom muaj kev twb kev txuas ntawm tau ntawm cov khoom thiab tus nqi nyob rau lwm yam.
