这里MPC=“所消耗的边缘投入”。事实上,经济学家们观察到I—0比率和Keynsion比率这种类似关系已有很长一段时间了。(Isard 1975) 业已表明,Salcedo发现了数字上与上式相一致的经验公式。两者之间的联系已由一个学者用图1描述出来。
Here MPC = “marginal input consumed ”. In fact, economists have observed a similar relationship between the I-0 ratio and the Keynsion ratio for a long time. (Isard 1975) It has been shown that Salcedo found empirical formulas that are numerically consistent with the above. The link between the two has been described by a scholar in Figure 1.
