Rybczynski Theorem: incazelo nemiphumela

Kusukela ekuzalweni emhlabeni ukudayisa theorists kwezomnotho baye bazama ukufunda ubudlelwane zonke izinqubo kusukela umbono wesayensi. Njengalezi physics, ukuthola theorems entsha futhi uchaze isimo, okuholela ekuncipheni noma ukwanda emnothweni wezwe. Isiqongo yentuthuko wezangaPhandle kwaba inkathi ofeleba kanye rearrangement amabutho emazweni omhlaba, nje kwaba ngemva kwezikhathi zokulotshwa impi. Kule ndaba zaziziningi eyeza nezazi zezinkanyezi ezikhuluma, kuhlanganise Rybczynski theorem. Kafushane futhi ngokucacile zama ukuchaza okushiwo kulesi sihloko.

imisuka

A abasha IsiZulu umfundi TM Rybczynski eminyakeni 45-50 kwekhulu elidlule, behlole imiphumela umkhakha emnothweni. Ngaleyo minyaka, waphumelela kwamaZwe, futhi eBrithani lalingu kwelinye lamazwe ahamba phambili e-ukuthekelisa kwezimpahla. Rybczynski Isiqondiso main sifundwa kwaba Heckscher-Ohlin theorem. Ngokusho zezinkolelo zalo, izwe ithumela kwamanye amazwe kuphela lezo ogama ukukhiqiza unakho yini okwanele kwemithombo, futhi ungenise lezo ezidinga kakhulu ngokushesha. Kunengqondo ukuphetha ngokuthi yonke into ngokuhleleka okunengqondo. Kodwa imfundiso yokuziphendukela ukusebenza, udinga ukuba acabangele izimo nesenzakalo zokwenana international:

1. Kukhona amazwe okungenani ezimbili, enye yazo izici zokukhiqiza ngokweqile, kanye nezinye ihlangabezana kusilela yayo.
2. Intengo senzeka ezingeni Ukuqhathanisa izinto zokukhiqiza kuphela.
3. Ukuhamba izici zokukhiqiza, okungukuthi, ukuba khona ukuthi kungenzeka kubenze (isibonelo, isiqephu sezwe ezokuthutha akunakwenzeka).

Ngemva kokuhlaziya ukuthuthukiswa kwamanye amazwe kwekhulu leminyaka elidlule, umfundi osakhula waletha umbono wakhe. Ngakho lapho Rybczynski theorem. isikhathi sakho ukuvela isanda ummango kanye nokwehla lamazwe isicebi 'kwezwe yesithathu "amazwe.

Amazwi Rybczynski theory

Ngakho, sekuyisikhathi ukwakha lokho luwumgogodla imfundiso yokuziphendukela Economist British. Wagomela ukuthi uma kunezinhlobo ezimbili kuphela izici ukwenziwa izimpahla, futhi uma sisilandela ukwandisa ukusetshenziswa eyodwa, Kwakuyohlanganisani kuncipha ukukhiqizwa kwezimpahla ngenxa Isici sesibili.

ukucaciseleka

Uma uthi nhlá, kubonakala kuyadida kakhulu Rybczynski theorem. Kafushane selisho umnyombo oyinhloko. Cabanga izinkampani ezimbili. Omunye ukhiqiza amakhompyutha okuyinto udinga eziningi dolobha, kwathi imali anayo ngokuchichimayo. Okunye ekutshaleni okusanhlamvu, okuyiwona futhi unalo izinsiza ezanele, ikakhulukazi ngenxa kwetisebenti. Le nkampani wokuqala timbiwa kumakhompyutha futhi ngenxa amanani eliphezulu ngaphezulu kwandisa nenhloko-dolobha yalo, enithi lukhula wonke amabutho luphumelele kuphela ubuchwepheshe ukukhiqizwa. Ngezinye efanayo imali isikhathi sokuba umkhiqizo wokusanhlamvu isiba zabasebenzi sazikhohlwa ukwazi ukungena kule mboni kube nenzuzo enkulu, futhi inkampani okonakele.

itulo

Rybczynski Theorem uthi isilinganiso izici bebheke zincishiswe noma ukukhulisa uyohlale umphumela wokugcina we zokukhiqiza, kungakhathaliseki kuthathwa njengesibikezelo wemboni ehlukile noma emnothweni iyonke. Cabanga igrafu.

Nalapha futhi, isibonelo esikhethekile ngeke baqonde indlela ukwandisa noma ukunciphisa izinto zokukhiqiza kuncike funa. Ngokusho idatha, kukhona X ezimbili izimpahla Y. Ngoba kumele ziqale dolobha wesibili - yezabasebenzi. I vector lokuqala OF libonisa indlela isilinganiso elilungile zomsebenzi nemali kuthatha ukukhiqiza X umkhiqizo ne ukukhula kwesidingo. Ngokufanayo, i-umkhiqizo Y, okuyinto Ibeka OE vector. I grafu ikhombisa iphuzu G. Lokhu imitfombolusito. Okungukuthi, kukhona isitokwe ezithile dolobha (GJ) kanye zabasebenzi (OJ). Ukuqinisekisa wezwe izimpahla X Y izidingo akhiqizwa ivolumu, ngokulandelana, F no E.

Rybczynski theorem kusekelwe nesanda isici. Ake sithi lo iyinhloko-dolobha. Manje, womshini umthamo omusha kwezimpahla Y (ukuthekelisa) kudingeka izimali ukuthi bamake ncamashi G _1. Inombolo peremesitsya umkhiqizo ukhombe E ₁ kanye nokwenyuka kwenani ubude BAYO _1. Ngesikhathi esifanayo, letitsintsa imali X kuzobonakala, futhi ngaleyo ndlela ukukhiqizwa elizowela ₁ FF igebe. Qaphela ukuthi EE1 ibanga GG ₁ ingasaphathwa. Lokhu kusho ukuthi ngisho ukunyakaza elincane yezimbangela (kule icala elinesijeziso sokufa) e emkhakheni ukuthekelisa kuholela ukwanda ongalingani kunombolo emphahleni.

"Isifo Dutch"

Rybczynski Theorem esikhathini eside kungaholela hhayi kuphela nokuyaphansi izimboni ngabanye, kodwa futhi ukuba ukwehla yokusimamisa umnotho wezwe lonke. Izibonelo emhlabeni entula lapho izinto eziza kuqala kuye kwaholela ukwanda kwamandla emali, ukukhula izinga lokushintshisana futhi ukwehla kwe-GDP. Lo mphumela ibizwa ngokuthi "isifo Dutch".

Igama "igciwane" luphakamile eNetherlands. Kwakulapho maphakathi nawo-70s kwekhulu elidlule kwakukhona obumbi kuqala.

Cishe ngalesi sikhathi Dutch wathola inothile igesi yemvelo eNorth Sea. Baye kuqalile ukuba banake enkulu ekukhiqizeni futhi ukuthekelisa kwalezi zinsiza. Kunengqondo ukuphetha ngokuthi ngaphansi kwezimo ezinjalo umnotho wezwe sasikhula, kodwa kube khona isimo okuphambene ngokuphelele. Course lwemali Dutch wakhula, begodu kukhula waphawula okusheshayo futhi eliphezulu kakhulu, kuyilapho nokuthengiswa nezinye izimpahla ezibalulekile ngokwethukela ninganciphi.

Nemiphumela "isifo Dutch"

Isizathu salokhu kwaba ukusetshenziswa kwemali kusukela imikhakha ithele imikhiqizo ubudala ekukhiqizeni igesi. Kukhula funa wakhula, aba maningi utshalomali okudingekayo. Isizinda of esiyigugu bafuna imali, ukusebenza, kanye nobuchwepheshe. Mayelana lemikhiqizo nezinye izifunda ukhohlwe ngokugxila eyodwa. Ngenxa yalokho - izinga lokushintshisana yanda, futhi ngaleyo ndlela, ukuncintisana yezwe.

Rybczynski Theorem waphinda kufakazela iqiniso lokuthi uhlelo lokuhlelwa kabusha izinkinga izinsiza ezingavela kokubili ukuhweba basekhaya nabamazwe angaphandle yezwe. "Dutch isifo" upokisi emazweni amaningi. Inkinga enkulu kwenzeka Colombia ngemuva kokwenyuka ukufunwa ikhofi. Hhayi lidlule kwegciwane amandla eziphambili European. walulama ngempumelelo UK, France, Norway.

isimangaliso kwezomnotho Japanese

Esinye isibonelo - Japan. Leli zwe elincane isiqhingi eminyakeni engu-60 yekhulu leminyaka elidlule, okunimangaze lonke umnotho womhlaba gxuma okusheshayo. Rybczynski theorem wasebenza lapha, kodwa futhi zibe nethonya elihle.

Zonke izifundazwe zingahlukaniswa zibe lezimpahla nezezimboni. Ezinye zithunyelwa eziphethe imakethe yomhlaba wonke ikakhulu imikhiqizo, okuyinto kuyoba impahla eluhlaza for imikhiqizo kwamanye amazwe. Kula mazwe eziningi Manpower, kodwa izimali ezincane. Olunye uhlobo ukuhweba - kuyinto exchange of imikhiqizo isiqedile. Njengomthetho, isimo, ukuthengisa emphahleni, babe kwemali ekhona kanye nobuchwepheshe. Ngenxa yokuthi isigaba sokuqala kufanele bathenge imikhiqizo ezibizayo ngaphezulu wesibili, abaphilayo zokugcina kahle.

Japan bakusebenzisa lokhu isimiso. On endaweni yayo encane sikhule into engenakwenzeka. Resources, kakhulu, cishe akukho. Konke - encane kanzima zokusebenza nabantu bayaphikelela. Ngenxa yokuvela kwezinto emkhakheni wama-computer, i-uwoyela negesi kusebenziswe futhi izimboni zamakhemikhali, Japan oye wakwazi kabusha umnotho wabo ukuze ngokuthenga izinto zokusetshenziswa ezishibhile, baye ke kusetshenzwe futhi ukhululeka emakethe izwe imikhiqizo ezibizayo esiphelele.

isiphetho

Rybczynski Theorem - i version ngcono imodeli Heckscher-Ohlin, owawuthi ezweni ithumela kwamanye amazwe izimpahla, womshini edinga imithombo ngokweqile, futhi ukungena eseqedile imikhiqizo, ezivuma ngeke. Zezomnotho bakholelwa ukuthi ukunwetshwa zokuthumela lezo eziye, nokunye ukudayiswa, a omkhulu ukwanda ukungeniswa kakade uthenge. Futhi, okuphambene nalokho. Uma ugxile yokungenisa izinqalasizinda eziyingcosana ngokuhamba kwesikhathi kuzonciphisa isidingo ukungena.
