First, the demand for automotive filters is on the rise
　　Ii. Fierce competition in the automotive filter market
　　The huge filter market has attracted the attention of many manufacturers. The entry of domestic and foreign enterprises has led to the increasingly fierce competition in the filter industry. More than 1000 domestic existing cleaner production enterprises, due to the structure of automotive filter products and diversity, not only suitable for mass production of high automation degree, also can be used for manual operation of small batch mill production, so most smaller production enterprises, large and medium-sized enterprises have more than 30, temporarily did not form a monopoly of large enterprises in the industry.
　　The fierce competition in the after-sales market is mainly caused by the following two reasons: first, the filter belongs to the wearing parts of the automobile and needs to be replaced regularly, so the sales volume in the after-sales market is very large, which directly leads to the number of filter enterprises competing for the after-sales market far more than the supporting market. Second, China's automotive filter industry manufacturers are numerous, and generally small, most of the production conditions are not complete, backward detection means, small scale of manual workshop type automotive filter enterprises, these enterprises basically can not meet the requirements of the supporting, so they can only compete in the after-sales market. Due to the fierce competition of enterprises, the brand concentration is very low in the after-sales market of filters, and the market share of the first five filter enterprises is only 15%. In the supporting market, the market share of the top five filter enterprises reached 40%.
　　Iii. Filter enterprises in the era of low profit turn to the supporting market
　　Although the after-sales market of filters is in great demand, as more and more enterprises enter this market, in fact, the after-sales market of filters has entered the era of small profit, and the profit space is still shrinking. In addition to the appreciation of the RMB, raw materials prices, all kinds of factors have made the difficulties of the enterprise is even worse, filter enterprises should how to break out?
　　The personage inside course of study says filter business should highlight encirclement must want to enter form a complete set market, because form a complete set the requirement of the market is very high, the business that enters is not very much, because this competes a circumstance to be opposite better, and profit space is opposite also taller. However, foreign-funded and joint-venture brands seize the market and almost monopolize the supporting market of filters for high-end models, so it is particularly important to improve the technical strength of our own brands.
　　Fortunately, some domestic filter manufacturers with a certain scale have realized this, and strive to enter the supporting market, although entering the supporting market enterprises will face this or that kind of difficulties, but this has become a trend.
