财政调控与国民收入预期

Fiscal Regulation and National Income Expectation

经济运行的正则性规定了经济因子之间的传递性,而固定替代弹性可以进一步给出这种传递性的精确测度。作为宏观调控的重要手段之一,政府的财政干预可以直接地作用于国民收入,从而导致国民收入向着预定的目标前进。然而,在以往的经济学范式(简称F函数)里,因为难以预测和计算潜在的国民收入水平,致使关于这种调控的真实效果难以得到精确的表示,甚至难以取得令人满意的近似。如今,经济学的范式进展到了有约束的利润函数(简称G函数),它可以很容易地接受有关财政政策与市场因子的初始陈述,从而容易实现有关数学模型的建立,进而,借助正则定律和固定替代弹性定律,可以容易地揭示出财政政策调控与国民收入预期之间的基本关系,并给出精确的测度。

The regularity of economic operation running defines the transitivity among the economic factors while the constant elasticity of substitution can predict the precise measurements of such transitivity. As one of the impor- tant macroeconomic control means, the government fiscal intervention can directly act on national income, thus guid- ing national income towards a predetermined goal. The past economics paradigms （F function for short）, however, have great difficulty in predicting and calculating the potential national income level, resulting in the difficulty of ac- curately or approximately presenting the real effects of such adjustments. Now the economics paradigms have pro- gressed into the phase of Restricted Profit Function （ G function for short）, which can easily receive and process the original statements about the fiscal policy and market factors so as to establish corresponding mathematical models. Based on such models and with the help of regular law and constant substitution elasticity law, the basic relations be- tween fiscal policy adjustment and national income expectation can be easily revealed and accurately measured.
