On the 3rd, the National Development and Reform Commission held a symposium to further improve the formation mechanism of refined oil prices and promote the further marketization of refined oil prices. It is expected that after the large-scale solicitation of opinions, the focus and direction of the improvement of the price mechanism will be basically clear, and the pace of the introduction of the new mechanism will accelerate.

NEST cell culture dishes are ideal for all types of culturing where microscopic examination is required. Numeric indicators on the bottom of each plate allow users to identify the location of cells.
Cell and tissue culture technologies have an increasing importance in the fields of basic and applied life science. New culture vessels and new surfaces for cell adsorption are continuously emerging, in order to simulate the internal environment as much as possible for culture of some
special cell lines. Logically, using permeable supports with a microporous membrane becomes the basic method for culturing these cells. Permeable supports may effectively improve the culture of polar cells, because these supports allow cells to secrete on and absorb molecules from their basal and apical surfaces to metabolize in a more natural way, as well as to stimulate the in vivo environment to the maximum extent for culturing of some special cell lines.
NEST cell culture plates have round edges for better handling. Low profile, low-evaporation lid design assure uniform growth. Tissue treated and non-treated are both available. Non-treated growth surface is more hydrophobic than tissue culture surface and are similar to the surface of a bacteriological Petri dish. Small feet on the bottom corners of each plate eliminate scraping of the microscope lens.

Discuss whether to set "ceiling price" and "floor price"
According to reports, delegates should set "ceiling price" and "floor price" on the refined oil price mechanism. How to determine the specific level, how to simplify and optimize the price adjustment method, how to ensure the safety of domestic oil supply, and promote energy structure adjustment and resources. I have expressed opinions on issues such as conservation and utilization. The meeting was attended by representatives of major oil companies, truck drivers, boat owners, taxi drivers, private car owners, industry associations, oil companies, experts and scholars.
Lin Boqiang, director of the Energy and Energy Collaborative Innovation Center of Xiamen University, said that it is not yet known whether to set the highest price and the lowest price, or to set the upper and lower floating range based on the reference price. If it is the highest price and the lowest price, he believes that the highest price has no meaning. The lowest price can protect the domestic oil industry when the international oil price is too low, because the cost of domestic production is much higher than that of the major oil producing countries. Lin Boqiang is more in favor of the ups and downs of the system, which is also a stage in the process of implementing full marketization.
The price adjustment of refined oil products experienced two “suspension†in December last year. On December 29, 2015, Xinhua News Agency reported that the refined oil price mechanism is seeking opinions from all sectors of the society. It is expected that the price of refined oil will continue to be temporarily adjusted before the new mechanism is introduced.
Two years of oil price adjustment was intervened
The solicitation of opinions was in the context of the removal of oil prices in the new edition of the Central Pricing Catalogue, while the long-selling international oil prices also accelerated the reform process.
In October last year, the National Development and Reform Commission announced the revised “Central Pricing Catalogueâ€, which will be implemented from January 1, 2016. The new version of the "Central Pricing Catalogue" 7 major items and 20 items have no "oil" words. The remarks suggest that the price of refined oil will temporarily be based on the current price formation mechanism, and timely adjustments will be made according to changes in oil prices in the international market, and the process of institutional reform will be fully liberalized.
On December 15 and 29, 2015, according to the current domestic refined oil pricing mechanism, the oil price should have been lowered twice, but the adjustments were all “suspended†and also due to ongoing price reforms. In fact, from 2014 to 2015, the relevant departments intervened in the adjustment of refined oil prices five times, due to the increase in consumption tax, or the serious haze and the reform of the refined oil pricing mechanism.
Xue Qun, an analyst at Longzhong Petrochemical Network, believes that the main problem in the current stage of refined oil price reform is that the profit distribution of the industry chain is uneven. At present, international crude oil prices have been at a low level for a long time. From the perspectives of exploration, refining, wholesale and retail, the profit distribution has already experienced a serious imbalance. From the overall perspective of the domestic refining industry, the exploration sector and the wholesale sector suffered serious losses, and the refining and retail sectors were profitable. The “uneven drought and flood†in the refining industry chain may push the reform of the refined oil pricing mechanism to speed up.
At the same time, he believes that the level of intervention by the relevant departments is too high. For a long time, China's refined oil products are in a monopoly pattern, and the pricing of refined oil products has not reached marketization. In 2015, the domestic oil market was accelerated, which paved the way for the accelerated marketization of refined oil prices.
Xue Qun also believes that the price of refined oil is unreasonable and the proportion of tax burden is too high. Taking the price of 92# gasoline in Beijing area on December 25, 2015 as an example, the composition of refined oil price is calculated: the current price of Chinese refined oil products accounts for 46.3% of the tax burden, of which consumption tax accounts for 27%. %, VAT accounts for 14%. This means that for every liter of oil added, consumers are required to pay a tax of 2.62 yuan.
