Opportunities and risks

The local auto parts industry pattern was weak, small, scattered state, although the larger scale of the industry, but the lack of economies of scale, and the field of key parts almost entirely foreign to occupy, the competitiveness of the industry is mainly reflected in the cheap labor and resource costs. From the behavioral analysis, the actions of China’s General Administration of Quality Supervision, Inspection and Quarantine, which only represented part of the efforts made by the Chinese government to support the national automotive parts enterprises, support has only just begun. The local auto parts enterprises with endogenous domestic import substitution, innovation and M & A colleagues, gradually mastered the core technology, the future promising.

Domestic import substitution market space

To understand China’s auto industry “market for technology” is successful, we must first look at the Commerce Department data. The data show that foreign control of the vast majority of market share of auto parts, domestic parts sales revenue accounted for only 20% -25% of the industry-wide, has a foreign background, auto parts manufacturers account for more than 75 percent of the industry as a whole, in these foreign suppliers, the wholly-owned enterprises accounted for 55%, Sino-foreign joint ventures accounted for 45% local parts are mainly used in self-brand cars, low market share. In the field of high-tech automotive electronics and engine parts, foreign market share up to 90%, the car’s fuel injection system, engine management systems, ABS and airbags, automatic transmission and other core components of the production, foreign proportionate share of 100%, 100% and 91%, 69%. It is not difficult to explain why China is the world’s car, not a car power, many joint venture plant in China just to get meager profit. Because access to most of the profits for mastering foreign companies. Now, Europe and the United States in the economic downturn, China’s own auto makers are With such a good opportunity, rapid mergers and acquisitions and break the key technologies, and occupy high ground, and then harvest the big cake of the Chinese automotive market. The so-called “sense of shame and then courage, issued by rock”!

Independent innovation and M & A peer-core technology is gradually formed

The lack of auto parts in China, mainly in the critical parts and high-end products. Now, however, has been a breakthrough. Among them, one of the path of a breakthrough, independent research and innovative development. For example, in the June 30, 2009, made the first high-end automatic transmission with fully independent intellectual property rights – Europa Germany full electronic control, low noise, high transmission ratio, the high applicability of a four-speed automatic transmission in China The trial production of the engine and transmission production base Neimengguou Italian German engine company is successful, it fills a gap in the core components of the manufacturing. Another way is through mergers and acquisitions, fast access to markets and technology. Far from Beijing Pacific (601,099, stock it) century, the acquisition of American General Motors Nextee steering system, Weichai acquisition of the French engine manufacturer MoteursBaudouin etc.. Near the huge car and youth car buying Saab. More Lingyun Group of the China North Industries Group’s other enterprises of the United Nations yesterday, the acquisition of 100% stake in Germany, Kai Yi, Germany. The equity acquisition marks China’s auto parts enterprises in the manufacturing of automotive locks have the world’s leading core technology, quality products, high-end customers, as well as R & D system. So, gradually grasp the core of Chinese auto parts enterprises, worth and long-term concern.

Continental said it will invest 5 billion rupees to improve productivity, enhance R & D capabilities . In addition, it will invest 3.3 billion rupees into the radial tire market in India .

Continental Executive Board member HelmutMatschi details explained continent annually to its plant in India to invest Rs 1 billion to upgrade the electronics devices , annual investment in R & D center in India 1.5 billion rupees.

Matschi also said Continental’s 2011 acquisition of India Modi tire , tire manufacturers , tire factory in mainland will Modi to invest 50 million euros (about Rs 3.3 billion ) , The plant will be launched in 2013 passenger cars and commercial vehicles with radial tires .
