摘要
在投资项目评估中，盈亏平衡分析是一种常用的方法，一般来说，它不考虑通货膨胀因素．但是由于通货膨胀的存在，盈亏平衡点会发生变化，这样投资项目评估的可靠性也将受到影响．文章在假定通货膨胀存在的条件下，通过对两种模型（模型Ⅰ和Ⅱ）的分析，发现模型Ⅱ的盈亏平衡产量小于模型Ⅰ的盈亏平衡产量，但二者都大于通常意义下的盈亏平衡产量．文中还阐述了通货膨胀条件下，盈亏平衡点不变的条件．
In inflationary times, prices of inputs and outputs do not necessarily change at the same rates. So the break-even point can be affected by inflation. Break-even analysis can be extended to cover two models in inflationary times. The implications of the two models are that part of the capacity can be set idle in each sub-period(Model Ⅰ), Whereas the production may be set idle after the break-even period(Model Ⅱ). The present paper shows that the conventional break-even analysis gives about the same results in inflationary times as long as the inflation is neutral; the general conclusion regarding the break-even point is that the requital volume of Model Ⅱ is smaller than that of Model Ⅰ;both are higher than under stable price conditions.
