Kupanga ntchito ya Cobb-Douglas - ziwiri chinthu lachitsanzo

Kuwonjezera zovuta multifactorial zitsanzo za kukula zachuma, nthawi zambiri ntchito chosavuta awiri, chinthu, chitsanzo. Cobb-Douglas - chitsanzo chimene chikusonyeza kudalira a linanena bungwe (Q) ya zinthu zimene analenga kuti: ndalama ntchito - (L) ndi ndalama likulu - (K).

Chuma akhala akuganizira yachiwiriyo zotheka kumanga ziwiri chinthu zitsanzo, kutenga nkhani za sayansi ndi luso patsogolo ndipo popanda kulembetsa.

Kupanga ntchito ya Cobb-Douglas zochokera NTP

Economic chitsanzo kuti amaganizira zomwe weniweni wa sayansi ndi luso patsogolo, ntchito ndi likulu waphindu. Izi zikachitika, n'zotheka kupeza phindu apamwamba pa mtengo womwewo wa ntchito ndi zida ntchito. Mu pempheroli, mitundu ina ya ZOWONJEZERA kuthandiza kuonjezera ndalama ndi kupereka ndalama ndalama ntchito, ena - kumabweretsa kuchepetsa ndalama. Woyamba mtundu wa ndalama zimabweretsa ndalama ntchito, ndipo chachiwiri - kupulumutsa likulu.

njira saganizira za NTP

M'nkhani ya chitsanzo cha chuma, pamene si n'komwe sayansi ndi luso patsogolo, likulu kudzikundikira kumachitika pansi ndalama zonse. Chuma kuphunzira kusonyeza kuti kugwiritsa ntchito njira zimenezi kumabweretsa kuchepetsa wa chomaliza mankhwala.

Pa dzanja limodzi, zinthu izi zingaoneke zachibadwa. Koma kwenikweni, zodabwitsazi N'kutheka kuti pa dzanja limodzi woyikidwa kukwaniritsa STP, Mosiyana ndi adatsutsa ndi mabizinezi, popeza palibe zolimbikitsa ochiza oyamba a zaluso mu ulimi. Chifukwa cha zimenezi, kampaniyo akuvutika ndalama zowonjezera kugula zida zatsopano amene si ntchito ndondomeko kupanga, koma chagona pa pepala bwino ndi kuchepetsa ntchito zake.

N'zosavuta kuona kuti pangakhale wapakatikati njira kuti kuphatikiza pa njira ziwiri anafotokoza.

Cobb Douglas chitsanzo kudziwa kukula

Kwa nthawi yoyamba chitsanzo ichi anali bungwe Knut Wicksell. Koma mu 1928, izo anayesedwa kuchita, chuma Cobb ndi Douglas. Kupanga ntchito ya Cobb-Douglas kudziwa mlingo wa okwana linanena bungwe Q ndi kuchuluka kwa khama padera likulu (L ndipo K).

Ntchito amaoneka ngati izi:

Q = A × Lα × Kβ

Kodi: Q - buku la kupanga;

L - Achita;

ndalama Capital - K;

A - zamakono zimachititsa

α - phindu ntchito ndalama elasticity;

β - mtengo ndalama elasticity.

Mwachitsanzo, taganizirani aone kuti pali Q = L0,78 K0,22. Mu aone kuti pali tikhoza kuona kuti mankhwala okwana gawo ntchito ndi 78% ndi gawo likulu - 22%.

Pochita chitsanzo cha Cobb-Douglas

Kupanga ntchito ya Cobb-Douglas zikusonyeza sangachite kuti ayenera kumwedwa kuganizira ntchito chitsanzo.

Kupanga mabuku ndi kuwonjezeka, pamene imodzi mwa njira zomwe akhala zikutsatiridwa, ndipo lachiwiri ndi kuchuluka. Ichi ndi chofunika kwambiri malamulo yoyamba ndi yachiwiri. Komanso, ngati wina wa zinthu chili ndi auka ena, aliyense malire wagawo kukula chinthu si monga ogwira ngati mtengo m'mbuyomu.

Pa mtengo zonse imayambitsa kuwonjezeka m'kupita kwa chinthu china chifukwa cha kuchepetsa kuchuluka mtengo linanena bungwe (Q). Ichi ndi wachitatu ndi wachinayi choletsa chitsanzo Cobb-Douglas.

Pochita chachisanu ndi chimodzi amati aliyense wa zinthu zokolola n'kofunika. Ndiko kuti, ngati wina wa zinthu 0, motero, ndipo Q kudzakhala ziro.
