An Empirical Study On The Promotion Of LNG Automobile Based On The Price Elasticity Of Oil And Gas

in recent years,the international crude oil prices continued to fall,domestic gasoline and diesel prices also followed after another cut,and the price of domestic natural gas but due to the introduction of relevant national policies,facing the rise in the overall trend,which is bound to make natural gas vehicle to attract the most people use price advantage becomes more and more obvious,face greater challenges to the promotion of LNG vehicle.To explore car with natural gas and gasoline and diesel,oil price of LNG vehicle demand influence,find out the natural gas of gasoline and diesel fuel is still the price advantage interval,for the government to formulate scientific and rational car with gas,vehicle fuel and other energy prices provided theoretical basis.In this paper,according to the relevant knowledge of microeconomics and Econometrics according to the research purpose,the model of the design theory,and collect the relevant data according to the model;using Eviews econometric software,the theoretical model of parameter estimation,parameter theory and application of mathematical statistics to the regression equation of test and estimation and the modification of the theory;combining the economics significance of the cross price elasticity of demand and price elasticity of demand for the theoretical model by the test parameters: ?₁??₂??₃ economic analysis and necessary analysis;combined with specific examples of the LNG automobile economic benefits,and according to the calculation of the current price under LNG the price affordability value principle.The results show that the vehicle price,per capita GDP fuel oil prices,Sichuan province can be explained by natural gas vehicles in our province 63.99% of the demand for natural gas,the corresponding policy related factors caused by the preference of consumers to check the expected future demand for cars can explain nearly 36% of natural gas in Sichuan Province;Sichuan for natural gas vehicles appear rigid demand caused by the natural gas price increases 1%,the demand for natural gas vehicles following growth of 1.84% in the two simultaneous growth of the situation;the vehicle fuel oil to natural gas vehicle are substitutes,a reduction of 1% fuel oil price car,users will be reduced by 4.73% for natural gas vehicle demand,resulting in a dramatic decline in oil prices after the natural gas automobile demand;the current LNG prices are still within the acceptable range of users,LNG car economic benefits than More obvious.
