profit making organisation The new classic "perfect" price mechanism The importance of gasoline was not recognized in the 19th century, when it was used in a great deal of kerosene. The oil refining then relied on simple distillation processes to separate the different components of the oil from the boiling point. The boiling point of the kerosene component is higher, and the use of safety when lighting lamps becomes the main product of crude oil refining, while gasoline and other components are often burned as fuel. By the mid - to late 19th century, the successful use of gasoline engines in 1886, in 1886, the gasoline engine was successfully used as a driving force, thus the importance of gasoline increased. But using distillation, only 20% of the gasoline can be extracted from crude oil. In 1911, the standard oil company have solved the problem of low gasoline yield, by William burton and Robert hamm forest thermal cracking process of the invention, the heavy quality heating gas oil cracking of light gasoline fractions, such as to overall improve the gasoline yield, thermal cracking process in 1913 won the patent license in the United States. The subsequent catalytic cracking process has further improved the gasoline yield and octane value. Profits of socialism and capitalism have substaintial distinction, is it to create value for the society, in order to expand socialist reproduction and improve people's living conditions, is the socialist accumulation and the main source of social consumption funds, is to measure and evaluate enterprises an important indicator of economic activity.

The market through information feedback directly affects the production of people, how much production, and the market time, product sales status, etc.; Middle link commodity economy development process, supply and sale, the parties to provide production, supply and sale parties exchange places and other exchange, exchange time, to realize the commodity producers, operators and consumers their own economic interests. So there is concern that the yield will not fall below the historic low of 2.4%.
