基于PVAR的經(jīng)濟增長、通貨膨脹與城鄉(xiāng)收入差距關系研究
[Abstract]:The overheating of economic growth, high inflation and the gradual widening of the income gap between urban and rural areas have all affected the construction of a harmonious society, which has become an urgent problem for our government to pay close attention to at present. Whether there is a certain interaction between them is worth further exploring. Firstly, this paper makes a systematic literature review of the relationship among the three, and the main body uses theoretical analysis and empirical analysis, qualitative analysis and quantitative analysis to study the mechanism of action among the three. Considering that the lack of data in the stage of 1978 / 2010 may lead to the distortion of empirical results, this paper selects the 1993 / 2010 data of 31 provinces and cities in China to construct PVAR model for comparative analysis. It is found that some conclusions obtained from 1978-2010 as samples are indeed inconsistent with the national conditions of our country, while the results of 1993-2010 model fit the economic growth well. The interaction between inflation and urban-rural income gap. The estimated results of PVAR model from 1993 to 2010 show that the interaction between inflation and urban-rural income gap varies from positive to negative or from negative to positive, respectively. Impulse response analysis shows that the same variable has the same or different response to the positive impact of different variables or different variables in the face of the positive impact of the same variable. The specific analysis is as follows: (1) the impact of economic growth on inflation is a process from positive to negative, which indicates that the extensive economic growth mode of our country will induce inflation to a great extent. However, the rapid growth of GDP and the stability of low CPI coexist, and the important economic goal of macroeconomic in the track of benign operation can also be achieved. Inflation, on the other hand, has been detrimental to economic growth. (2) Economic growth first has a negative impact on the income gap between urban and rural areas, which may become positive from the changing trend. The effect of urban-rural income gap on economic growth has gone through a process from negative to positive. (3) the impact of urban-rural income gap on inflation has gone through a process from negative to positive. Inflation first suppresses the widening of the income gap between urban and rural areas. From the changing trend, inflation will promote the widening of the income gap between urban and rural areas. Variance decomposition shows that although most of the variation of standard deviation of each variable can be explained by its own change, the change of the other two variables also has a certain influence on it, and the contribution rate of some variables is relatively large. The existence of such a close relationship among the three guides the country to take into account the degree of inflation and the income gap between urban and rural areas at the same time of economic development, and to minimize the adverse effects among the three, which will have important theoretical and practical research significance. In view of these conclusions, this paper finally gives the corresponding policy recommendations, in addition, in view of the shortcomings of the paper, this paper also puts forward some research prospects.
