The Incremental Capital-Output Ratio (ICOR), is the ratio of investment to growth which is equal to 1 divided by the marginal product of capital. The higher the ICOR, the lower the productivity of capital or the marginal efficiency of capital. The ICOR can be thought of as a measure of the inefficiency with which capital is used. In most countries the ICOR is in the neighborhood of 3. It is a topic discussed in Economic growth. K: capital stock Y: output (GDP) I: net investment According to this formula the incremental capital output ratio can be computed by dividing the investment share in GDP by the rate of growth of GDP. ==ICOR, world, and determining variables== File:IQuoteWeltEngl.PNG|Investment share File:WeltBIPWorldgroupOECDengl.PNG|Rate of GDP growth File:IcorWorld.PNG|The reciprocal of ICOR File:MEoC.png|Marginal efficiency of capital as defined in the Ameco data bank of the European Commission for FRG, USA and Japan. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Incremental capital-output ratio」の詳細全文を読む スポンサード リンク
