In the first four quarters of 2015, China's auto sales increased by 3.91%, -1.04%, -2.35% and 15.84% respectively.
Second, the output of new energy vehicles was nearly 380,000. In 2015, a total of 379,000 new energy vehicles were produced, a four-fold increase over the same period last year. Among them, the production of pure electric passenger vehicles was 142,800 units, a three-fold increase over the same period of last year. The production of plug-in hybrid passenger vehicles was 63,600 units, a three-fold increase over the same period of last year. The production of pure electric commercial vehicles was 147,900 units, an increase of eight times. Electric hybrid commercial vehicles produced 24,600 units, a year-on-year increase of 79%.
Third, the 1.6-liter and below displacement passenger car market is developing steadily, and the energy-saving and environmentally-friendly passenger car market is growing rapidly. In 2015, the market share of passenger cars with a displacement of 1.6 liters and below was basically flat, and the market share of small-displacement vehicles gradually recovered. . In 2015, 1.6 liters and below displacement passenger cars sold a total of 14.508 million vehicles, an increase of 10.42%; accounting for 68.6% of the passenger vehicle sales market, an increase of 1.87 percentage points compared with 2014; accounting for 58.98% of the automobile sales market , an increase of 3.02 percentage points over 2014.
According to the statistics of the complete vehicle certification of motor vehicles, the 272 models listed in the “Promotion Catalogue of Energy-saving Products Huimin Project Energy-saving and Environmentally Friendly Vehicles (1.6L and below Passenger Vehicles)†(first and second batch), mass production in December There are 151 models with a total production of 274,200 units, a decrease of 3.50% compared with November.
Fourth, the market share of passenger car's own brand increased In 2015, the sales of self-owned brand passenger cars reached 8,737,600, a year-on-year increase of 15.3%, accounting for 41.3% of the passenger car sales market, and the market share increased by 2.9 percentage points year-on-year. Among them, the sales of self-owned brand cars was 2,430,300, down 12.5% ​​year-on-year, accounting for 20.7% of the car market, and the market share decreased by 1.7 percentage points year-on-year.
V. Declining economic benefits of enterprises From January to November 2015, 17 key enterprises (groups) realized a total operating income of 2,795.136 billion yuan, down 0.6% year-on-year; the total profit and tax was 493.096 billion yuan, down 1.4% year-on-year.
Sixth, the industrial concentration of large enterprise groups remained basically the same. In 2015, the production and sales scale of six automobile production enterprises (groups) exceeded 1 million, of which SAIC sales exceeded 5 million units, reaching 5.863 million units, Dongfeng, FAW, Changan, Beiqi and Guangzhou Automobile. It reached 3.872 million units, 2,843,800 units, 2,776,500 units, 2,489,900 units and 1,303,100 units respectively. In the first five companies (groups), a total of 17.8453 million vehicles were sold in 2015, accounting for 72.6% of the total automobile sales, and the concentration of the automobile industry decreased by 2.1%.
The top ten enterprise groups in China sold a total of 22,600 vehicles, accounting for 89.5% of the total vehicle sales. The concentration of the automobile industry was consistent with the same period.
7. Import and export of automobile vehicles continued to fall. From January to November 2015, China's total vehicle exports totaled 699,400 units, down 18.3% year-on-year, of which passenger cars exported 354,400 units, down 20.0% year-on-year; commercial vehicles exported 354,000 units.

From January to November 2015, the total import and export volume of national automobile products was US$166.037 billion, a year-on-year increase of 13.8%. The import value was US$ 89.681 billion, a year-on-year increase of 20.3%, and the export value was US$ 76.656 billion, a year-on-year increase of 6.6%.
Bonded Ndfeb Magnets are manufactured by binding rapid-quenching NdFeB powder. The powder is mixed with resin to form a magnet by compression molding with epoxy or infection molding with nylon. Bonded NdFeB magnets are manufactured by binding rapid-quenching NdFeB powder. The powder is mixed with resin to form a magnet by compression molding with epoxy or infection molding with nylon. The latter technique is particular effective in large volume production, though the magnetic value of products is lower than those made with compression molding because of their relatively lower density. Various shapes of high dimensional accuracy can be produced without further processing. Surface is treated by epoxy coating or nickel-plating to prevent corrosion
With different ratio of additives to NdFeB powder, magnetic properties of hybrid NdFeB magnets can be tuned in a wide range. Once the ratio is fixed, magnetic property fluctuation can still be limited in a narrow bank. Hybrid magnets will meet customerˇŻs specified properties.
Rapidly quenched NdFeB powder used for bonded magnets is multi grain with grain size of sub-micron. Powder is isotropic in magnetic properties, which results in flat increasing of remanence and intrinsic coercivity with applied field. Magnet can only be magnetized to saturation in high fields.
