投入产出

The Chinese 6-sector computable nonlinear dynamic input output model and the method for determining its parameters are given in this paper. 给出中国六部门可计算非线性动态投入产出模型的构模原理，以及如何依实际数据设定模型参数的方法。

Based on kinetic principle and the Iaw of inputand output, we have studied the contarnination factors of agri-cultural Iands around a Iead and zinc metallurgical plant. 运用动力学原理和投入产出法则研究了浙江省某铅锌冶炼厂周围农业土壤中镉的污染因素。
