摘　　要：无差异曲线斜率递减，从数学角度来说不成立，但在一定的界域可赋予它合理解释。投资乘数具有倍增作用，其数学基础在于级数收敛原理。经济曲线以因变量作横轴、自变量作纵轴，这种有别于数学常规的坐标变换有其历史渊源。Indifference curve is negatively sloped. It does not hold from the mathematical point of view, but in certain domains, it has a reasonable explanation. Multiplier effect of investment leads to increased consumption spending and so results in an increase in national income greater than the initial amount of spending. It is mathematically based on the principle of progression convergence. The economic curve use dependent variable for the horizontal axis, and the independent variable for the vertical axis. This coordinate transformation is different from the conventional mathematics,and it has its historical reasons.

关 键 词：无差异曲线 投资乘数 经济曲线
