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. According to two assumptions in the model of the impact of input-output prices: without considering the impact of supply and demand factors and without considering the government regulation of prices, the model of the impact of input-output prices has been further developed and improved, the supply and demand and government-controlled variables , The two variables are introduced into the model, and the influence model of input-output price considering the relationship between supply and demand and government regulation and control is established, which makes the model closer to the actual situation of economic operation and more suitable for the analysis of practical problems.
