【摘要】 针对投入产出价格影响模型中的两个假定:不考虑供求因素影响和不考虑政府对价格的调控,对投入产出价格影响模型做了进一步发展和改进,定义了供求影响变量和政府控制变量,将这两个变量引入模型,分别建立了考虑供求关系因素和考虑政府调控因素的投入产出价格影响模型,使得模型更接近经济运行的实际情况,更适合实际问题的分析.更多还原

【Abstract】 When analyzing the price impact of certain products’ price changes on others,the IO price model has two assumptions: without considering the demand-supply relations,and the government’s control on price system.According to the two assumptions,we propose the improved input-output price model,by introducing the supply-demand influential variable and the policy influential variable into the classical model separately.The improved model is much closer to the economic reality,and more suitable for the analysis of practical problems than the classical model.更多还原
