摘　　要：以我国西部某化工园区的规划数据为例,通过建立甲醇及其下游产业链实物型投入产出模型,对该产业链中不同产品部门之间的相互作用进行了定量分析。结果表明:该园区甲醇下游产业链中缺乏强拉动及强支撑作用的产品部门;丙烯酸异辛酯、混合C_(4)等对产业链发展具有较强的拉动作用;原材料甲醇的感应度系数高达21.808,对整条产业链具有较强的制约性。Taking the planning data of a chemical park in western China as an example,a physical input-output model of methanol and its downstream industrial chain was established to quantitatively analyze the interaction among different product sectors of the industrial chain.The results indicated that there were lack of product sectors with strong driving force in the methanol downstream industry chain of the park.While isooctyl acrylate,mixed C_(4),etc.had some effects on the development of the industrial chain,the sensitivity coefficient of raw material methanol was as high as 21.808,showing strong constraint on the entire industrial chain.
