We found some results by implementing elasticity analysis. Most variables have significant impacts on gasoline demand and diesel demand. The sale volume of gasoline increases as the increase of personal disposable income (PDI) and quantity of car. The sale volume of gasoline decreases as the increase of gasoline price, interaction of quantity of car and motorcycle and quantity of bus. Besides, the sale volume of diesel increases as the increase of PDI, quantity of truck and bus and index of production-manufacturing (INPM). The sale volume of diesel decreases as the increase of diesel price. Moreover, seasonal variables have significant impacts on both gasoline demand and diesel demand. In winter, the sale volume of gasoline is the least, and the sale volume of diesel is the most. Furthermore, the growth rate analysis also brings us some interesting outcomes. The growth rate of sale volume of gasoline increases as the increases of quantity of car. The growth rate of sale volume of gasoline decreases as the increase of gasoline price and the increase of quantity of bus. Besides, there are several variables have significant impacts on diesel. The growth rate of sale volume of diesel increases as the increase of PDI, INPM and quantity of truck. The growth rate of sale volume of diesel decreases as the increase of diesel price and quantity of bus. There are only season 1 has significant negative impact on the growth rate of sale volume of diesel. According to above conclusion, two policy implications are derived. First, since the impact of car on the gasoline demand is offset by motorcycle, the government should provide more subsidy for motorcycle in order to reduce the gasoline demand and gas emission. Second, the government can develop public transportation to reduce the demand of gasoline. Public transportation including buses, mass rapid transit and high speed rail, etc.
