[Abstract]:At present, China's price operation has begun to rise again. The Central Bank of China's monetary policy implementation report in the fourth quarter of 2012 has proposed to guard against inflation expected risk and prevent input inflationary pressure. The UK Financial Times published an article suggesting that governments should take precautions against global inflation pressure in 2013 and take preemptive measures. To control inflation, these new situations can explore the mechanism and process of inflation formation from the angle of price fluctuation correlation, and put forward some pertinent countermeasures and suggestions for price regulation.
The previous scholars mainly use the input and output price model to study the correlation effect of price fluctuation. Because there are very difficult problems in the dismantling and input-output table, there are few research results on the correlation effect between the price fluctuation of large sample consumer goods. Price researchers and government price management departments provide simple and feasible research tools and methods.
In this paper, price volatility association effect is regarded as a network communication mechanism that obeys a certain law of communication. The relationship effect of price fluctuation in Guangdong is studied by introducing the perspective of network communication. First, the model of price fluctuation, which is often used in economics, is based on the model of price impact based on input-output theory, in 2007, 135 in Guangdong province. Based on the Department value input-output table, the input and output table of 9 departments and 30 sectors (or consumer goods) is established by the method of dismantling and dismantling. On this basis, the price impact model of Guangdong is established, the correlation effect of price fluctuation is calculated, and the beta coefficient (beta), the conductivity (gamma) and the external of the financial management are introduced. The 3 parameters of sensitivity (theta) have been improved on the price impact model, and the model of Guangdong price fluctuation is established under the change of supply and demand and the open condition. In order to overcome the difficulty of dismantling and input-output table due to the use of price influence model to study the correlation effect of price fluctuation, the method of network communication is tried to use the price. The correlation effect of price fluctuation under the model is projected onto the network, and the price fluctuation network model is established to simulate the price fluctuation correlation effect under the price influence model, and it is found that the agreement degree is high. On the basis of simulation, the price fluctuation network propagation model is extended to study the correlation effect of the price fluctuation of 240 kinds of consumer goods. A comprehensive network communication model of price fluctuation association effect is established, and the variation of the correlation effect of price fluctuation in consumer goods before and after the 2008 international financial crisis is studied.
The research has achieved the following innovative results:
1. as a network communication perspective, the price fluctuation association effect is regarded as a network communication mechanism that obeys the law of some kind of communication. The network propagation model of price fluctuation is constructed, and the correlation effect of the price fluctuation of large sample consumer goods is calculated, which can provide a relatively simple method for the study of the correlation effect of the price fluctuation of consumer goods. The price fluctuation model is used to study the correlation effect of the price fluctuation of consumer goods. It is inevitable to meet the problem of dismantling and input-output table. It can only study the correlation effect of the price fluctuation of single or small consumer goods, and can not calculate the influence of price fluctuation among the large sample consumer goods. The dynamic association effect can avoid the difficulty of the dismantling and input-output table due to the use of the price impact model to study the correlation effect of price fluctuation. At the same time, it can measure the correlation effect of the price fluctuation of the large sample consumer goods in Guangdong, and provide the reference basis for the government price regulation and control decision.
2. explore the network communication mechanism which is consistent with the effect of price fluctuation under the input-output price model, and project the price fluctuation correlation effect based on the price impact model to the network, and construct the price fluctuation association effect projection network. On the basis of analyzing the network extension structure, the network communication method is introduced. Through the correlation coefficient between the time series of the consumer price index, the price fluctuation association network and its propagation equation (namely the price fluctuation network transmission mechanism) are established to simulate the price fluctuation correlation effect under the price influence model, and it is found that the analog anastomosis is high. The fixed propagation equation is constant, and then the modified network threshold is constantly adjusted (the network topology is changed accordingly). The correlation effect of the price fluctuation of consumer goods through the network communication simulation is nearly close to the price fluctuation correlation effect under the price influence model, and it can provide a new way for the construction of the network propagation mechanism of the price lattice fluctuation.
3. the model is established to reflect the change of supply and demand and the price influence under the open condition. It calculates the market competition and the interaction between the price fluctuation of consumer goods under the high dependence degree. The article introduces the beta coefficient (beta), the conductivity (gamma) and the external sensitivity (theta) of the financial financial management to express the market supply respectively. The correlation effect model of Guangdong price fluctuation is established under the change of supply and demand and the open condition. The correlation effect between the price fluctuation of consumer goods in Guangdong is calculated by this model. This makes up for the former model of the use of input and output price. When the price fluctuation is related to the effect, it can not fully reflect the relationship between supply and demand of the market, the international market and other factors on the price fluctuation related effect of insufficient.
