成品油消費(fèi)稅稅率改變對(duì)消費(fèi)需求的影響研究
[Abstract]:With the increase of per capita disposable income and the acceleration of industrialization, the demand for refined oil in China has increased year by year. In 2014, the consumption of gasoline and diesel oil in China was 97.76 million tons and 171.65 million tons respectively. Oil products play an important role in economic development, especially in industry, agriculture, storage and transportation. In the long-term, our country's refined oil consumption demand growth space is still large. However, the increasing demand for oil products not only brings about rapid economic development, but also produces negative environmental externalities, such as carbon oxides, nitrogen oxides, sulfur dioxide, particulate matter and other air pollutants. How to find a balance between economic development and environmental pollution control? Paying for the environment, let the environment as a cost to consumers, may be the solution. So, as an environmental tax, can consumption tax affect the consumption behavior of refined oil effectively? What are the main factors that affect the consumption behavior of refined oil? In this paper, the relationship between consumption tax and consumption demand is studied by taking the consumption tax of gasoline and diesel in the subcatalogue of refined oil as an example. Considering irrational consumption behavior, the price of consumption tax is distinguished from that without consumption tax in order to quantitatively study their influence on consumption behavior. In view of the relationship between consumption tax and consumption demand of refined oil, this paper makes use of total time series consumption data and panel consumption data of 20 provinces (cities) to consider all kinds of factors affecting consumption behavior: excluding consumption tax price. Unit tax (tax rate), per capita disposable income, price index, per capita car ownership, people's livelihood expenditure level, urbanization rate, unemployment rate, policy fictitious variable, etc. On the basis of multivariate linear regression, a double-logarithmic linear model is established, and the regression equation is obtained by estimating the coefficients of the model with ordinary least squares. Then, the elasticity of price demand and tax demand is analyzed. In the time series data model, according to the adjustment of the determinable coefficient, the t test accompanying p value, the standard error of regression coefficient and so on, the regression model with good fitting effect is selected, and then the econometrics tests of heteroscedasticity, autocorrelation and so on are carried out. Then, by means of tool variable method, the price of refined oil is replaced by the price of international crude oil, and the exogenous problem of oil price is verified to ensure the establishment of the model correctly. In the panel data model, the general least square method of panel data is also used to estimate the regression coefficients of the fully interpreted variable model, and then the full interpretation variable model is improved by capturing the different heteroscedasticity of different regions. Finally, the causes of the model results are analyzed. By establishing the double logarithmic model of the oil products market, the paper concludes that the influence of the price without tax and the tax rate on the consumption demand is negative, and the influence of the change of tax rate on the consumption demand is greater than the change of the price without tax. From the point of view of elasticity, that is, the demand elasticity of tax is greater than that of price without tax, and tax is prominent. The influence of per capita disposable income and time virtual variables on consumption demand is also significant. Panel data capture heteroscedasticity between different regions, to some extent, the improvement of temporal data. By comparing and analyzing the different regression coefficients of gasoline market and diesel market, it is found that the degree of tax salience varies not only with different regions, but also with different consumer markets. Therefore, the consumption tax of refined oil can effectively affect consumption behavior, reduce carbon emissions in the air, achieve "energy saving and emission reduction", and control environmental pollution.
