The Research Of The Input-output Price Model And Empirical Analysis

The input-output theory was first proposed in 1936 by American economist Wassily Leontief. The 70-odd years later that the theory is quickly popular in the world, and have become a major national accounts analysis tools. On the study of the theory and application, the input-output price model has always been an important issue in the field. Chinese scholars have done many researches in the input-output price model, but all remain in the single-sector input-output price model, simultaneous multi-sectoral input-output price model.Do more researches in input-output price model help us to apply the input-output model, and used to guide, monitor the operation of our national economy.In this paper, we mainly get the following results based on the previous results.(1).Analyze the case that the multi-sectoral price changes, we proved that the equation of price changes is linear and additive, and also gets the formula of multi-sectoral input-output price model asynchronous:Compared with the formal of multi-sectoral input-output price model Syn-chronous, which will be applied as a general formula. Meanwhile, we proved that the impact on other sectors in multi-sectoral input-output price model Syn-chronous and the formal of multi-sectoral input-output price model asynchronous are equivalent (Theorem 3). Thus, we only consider the interaction of the sections which the price changes based on the traditional input-output price model.(2).Consider the impact of government regulation. Government regulation is one of the government's price regulations, government price control departments, can be as price changes sector, or as the departments affected by other sectors. We get the formula of the input and output price model under the government regulation.(3).I consider the sector to increase and to merger on the impact of input-output price model, which can be combined for the sector to increase or products in various departments under the unified tax rate which should reach a reasonable basis given price level. The formula of the input and output, price model with the sector to increase is as follows:The formula of the input and output price model with multi-sectoral merger is as follows:(4).Based on the Chinese input-output tables of 42 sectors in 2007, considered the construction and real estate sector price changes, we get the effect on other sectors when the real estate prices rose by 10%; and considered the construction industry rose 5%, real estate prices rose 10%, we get the effect on other sectors, and also verify the correctness of Theorem 3.
