讨论了发展中国家或地区在发展毛纺织工业时，有关原料供应、市场销售和主导行业结构优化等对策中需要定量分析一些问题．在分析预测毛纺织原料系统时，使用能体现社会系统特点的系统动力学模型，给出了简单的的系统动力学模型流程图．改变微观措施和宏观措施的变量值，可以得到有效的对等方案．通过预测人口变化、国民收入变化、积累率和衣着消费比等可计算出毛纺织产品的国内市场容量．对于外贸，主要说明以获得最大效益来确定出。产品结构的线性规划法，给出了目标函数和约束条件．文中还提出了主导行业选择的原则和具体的评价指标，给出了以调整投资比例为手段的行业结构优化程序困．按上述方法对某地区得到的结呆和实际相符．
Discussed in developing countries or regions in the development of wool textile industry, related raw material supply, market sales and optimization of leading industry structure and other countermeasures need to quantitatively analyze some issues. In analyzing and predicting wool textile raw material systems, using a system dynamics model that can reflect the characteristics of social systems, a simple system dynamics model flow chart is given. Changing the values of variables for micro-measures and macro-measures can lead to effective peer-to-peer schemes. The domestic market capacity of wool textile products can be calculated by predicting demographic changes, national income changes, accumulation rates, and clothing consumption ratios. For foreign trade, the main explanation is to determine the maximum benefit. The linear programming method of product structure gives the objective function and constraint conditions. The paper also puts forward the principle of leading industry selection and specific evaluation indicators, and gives the industrial structure optimization program which is based on the adjustment of investment ratio. According to the above method, the stagnation obtained in a certain area matches the actual situation.
