The China's Demonstration Model Of Macro-economic Model

This article calculates GDP from the expenditure approach to draw out the identical equation GDP =C+I+G+EX , according to the existing economic theory to assume the expend function, the investment function, the import and export function simplily and fully, then according to demand and the supplies theory in money market, the Fischer equality as well as the inflation and the unemployment relations to establish a small macroeconomic model.This model is a simultaneous equation, intercepts macro economic data of our country between 1990-2006 year, makes the parameter estimation with econometrics' estimate method to this simultaneous equation, the results indicate that the data estimation and the economic theory are the same completely, carries on the linear simulation to this model, the effect is good, after then according to our country's financial circumstance after 2007 and this model to carry on the simulation of economic policy between 2007-2010 year.
