基于中国1990—2010年的投入产出表数据,本文通过计算各项最终需求对工业行业的生产诱发系数和工业行业对最终需求的依存度系数等指标,研究发现投资需求对工业行业的拉动作用明显,工业行业对投资的依赖程度逐年上升,消费需求对工业行业的拉动作用较差,工业行业对消费的依赖程度趋于下降,出口对工业行业的作用受国际经济波动影响显著,各项最终需求对不同工业行业的影响差异明显,应在采取长短结合的政策中区别对待。
Based on the input-output data of China from 1990 to 2010, this paper studies the effects of investment demand on industry through calculating the index of production-induced coefficient of each final demand to the industrial sector and the dependence index of industrial demand on the final demand Obviously, the reliance of the industrial sector on investment has been increasing year by year. Consumption demand has been less favorable to the industrial sector. The dependence of the industrial sector on consumption tends to decline. The role of exports in the industrial sector has been significantly affected by the international economic fluctuations. The impact of demand on different industrial sectors is obviously different and should be treated differently in the policy of combining length with one another.
