传统外贸贡献计算方法的反思及改进

传统的外贸贡献计算方法割裂了各经济变量之间的联系，没有充分考虑出口对国内消费和投资的影响，因而，这一方法存在低估外贸对我国经济增长的作用的倾向，有鉴于此，章在充分考虑各经济变量之间的内在联系的基础上，构建一个联立方程组以重新估算外贸对我国经济增长的贡献程度。

Improvement of the Traditional Calculating Method

The traditional calculating method of the contribution of foreign trade cuts apart the connection between every economic variable.In addition,the influences of import and export on the domestic consumption and investment are not taken into acount by the method.Therefore,there is a tendency of underestimating the contribution of foreign trade to our country's economic growth.In view of this,based on fully considering the inherent link between every economic variables,this article proposes a group of simultaneous equations in order to re-estimate the contribution of foreign trade to China's economic growth.
