交叉乘积

Firstly, the paper sets up a rational function model for the long run relationship between economic growth rate and the inflation rate by adding the cross product term of the both into the traditional model of "output-price" Phillips curve. The empirical analysis shows that the product term has substantial impact on the model\'s stability.

第一，本文在传统"产出一物价"型Phillips曲线长期模型中，加入了表现经济增长率与通货膨胀率乘积效应的交叉乘积项，建立了表现二者之间长期关系的有理函数模型。
