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 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 支出,剩余的用于儲蓄 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: 儲蓄全部自動轉(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蓄起來 用于投資,實現(xiàn)持續(xù)不斷的增長過程。 2022/5/29 7 模型: 經(jīng)濟增長率 = 平 均 儲 蓄 率 資本 產(chǎn)出比率 注:有保證的經(jīng)濟增長率 ——在長期中能使計劃的 儲蓄與計劃的投資相等,從而使經(jīng)濟實現(xiàn)長期 穩(wěn)定的增長率。 K K = C ( 資本量)這一公式反
