Data provided by the State Information Center shows that when it comes to car ownership in metropolises like Beijing and Shanghai, the average is about 200 vehicles for every 1,000 people. In most second- and third-tier cities, that number drops to 100, while for 20 of the country's 34 provinces and autonomous regions, the average is no more than 30 automobiles for every 1,000 people.

In eastern Shandong province, for example, the two largest vehicle markets - Jinan, the capital, and Qingdao - reported sales growth of 58 percent in 2009, while smaller cities like Weifang saw a sales surge by 91 percent year-on-year.

"China's fast-growing urbanization also indicates that, in the near future, second- and third-tier cities will be the major power driving auto sales," said Xu Changming at the State Information Center.

Jia Xinguang, another independent Beijing analyst, added that he is pleased that automakers "dig the potential" of fourth- or fifth-tier cities.

US automaker Ford's joint venture, Chang'an Ford, opened 40 4S stores (sales, service, spare parts and survey) on Nov 25, mainly in small cities in northern and western regions.

"Small, developing cities are our major target for the near future," said He Junjie, general manager of sales for Chang'an Ford.

Mercedes-Benz, the German luxury brand, has also been expanding into fourth- and fifth-tier cities since 2009, when it opened its first county-level 4S store in Cixi, Zhejiang province. The Cixi showroom sells more than 1,500 units a year and is listed as a best-seller, said a spokesman.

"Zhejiang is the champion of China's luxury car sales, yet its capital, Hangzhou, contributes only 20 percent of total sales, with the rest coming from second- and third-tier cities," said Cheng Zhengzhong, general manager of car dealers in Zhejiang Baolide Group.

Last November, Klaus Maier, president and chief executive of Mercedes-Benz China, paid a visit to the company's second county-level dealership in Zhuji, Zhejiang, to highlight his focus on small city markets. He said he was pleasantly surprised by the branch's ability to sell more than 100 luxury cars since its launch in late July.

Maier told China Daily that Mercedes-Benz will continue to add 25 to 30 4S stores annually in the coming years, with most in low-tier cities.

As Beijing's traffic control policy will greatly increase the purchase and usage costs of a car, industry experts predict the move will spell the end for homegrown automakers, which currently dominate the nation's low-end market.

"It will be the biggest impact ever suffered by domestic auto brands," said Su Hui, an analyst with the China Automobile Dealers' Association, who suggested they "focus more than 90 percent of their efforts outside first-tier cities, and further establish dealer networks in third- and fourth-tier cities".

Chinese companies should also further improve the quality of their products, as consumers in the third- and fourth-tier cities always want reliable, high-quality cars at low prices, he added.

Fellow analyst Zhong recommended both foreign and domestic automakers boost service quality to strengthen their competitiveness as the market matures.
