在产业经济学中,影响力系数和感应度系数是常用的评价产业部门拉动作用和推动作用的方法。本文针对影响力系数和感应度系数的缺陷,采用主成分分析法对投入产出表中的完全消耗系数进行研究,分析产业关联度,以确定国民经济主导产业。最后以中国1997年投入产出表为例进行了分析。结果表明,本方法更加符合实际,具有重要的参考价值。
The response coefficient and influence coefficient are often used to appraise the tensile and impulse action of every industry in industrial economics. In this paper, aimed at the defect of the response coefficient and influence coefficient, principal component analysis is applied to total input coefficients of input-output table. With the method we analyze the industrial relevancy to define the leading industries of national economy. Also the input-output table of China in 1997 is analyzed as an example. The outcome shows that the method in this paper has more value in application.
