R GYOWTH MODEL 2022/5/29 5 假設(shè)條件: 只生產(chǎn)一種產(chǎn)品(它既可消費(fèi)又可投資) Overall society only products a kind of output which can be consumed as well as product other output. 生產(chǎn)要素只有資本、勞動(dòng) 資本 產(chǎn)出比例不變 There are only two product elements: capital and labor. The ratio is invariable. GNP只在資本家、勞動(dòng)者之間分配 GNP is distributed between workers in wage and capitalists in profit according to the marginal utility. 分配到資本家手中的 GDP一部分用于消費(fèi) 支出,剩余的用于儲(chǔ)蓄 The profits in capitalists’ hands, partly for consumption, the surplus for deposit which will automatically change into investment. 2022/5/29 6 前提條件: 儲(chǔ)蓄全部自動(dòng)轉(zhuǎn)化為投資,投資根據(jù)固定比例的 資本 產(chǎn)出率轉(zhuǎn)化為增加的產(chǎn)出( GDP); 這一增大了的 GDP又能按照一定的比例儲(chǔ)蓄起來 用于投資,實(shí)現(xiàn)持續(xù)不斷的增長(zhǎng)過程。 2022/5/29 7 模型: 經(jīng)濟(jì)增長(zhǎng)率 = 平 均 儲(chǔ) 蓄 率 資本 產(chǎn)出比率 注:有保證的經(jīng)濟(jì)增長(zhǎng)率 ——在長(zhǎng)期中能使計(jì)劃的 儲(chǔ)蓄與計(jì)劃的投資相等,從而使經(jīng)濟(jì)實(shí)現(xiàn)長(zhǎng)期 穩(wěn)定的增長(zhǎng)率。 K K = C ( 資本量)這一公式反
