New homes in downtown Shanghai, or those within the city's Inner Ring, or downtown, sold for an average of 87,426 yuan ($12,700; 11,900 euros; 10,400) a square meter last year, an indication that the aspirations of younger people to own a home in the city center are becoming ever more elusive, industry experts say.

In contrast, the average price of homes between the Inner and Outer Ring was 44,984 yuan per sq m, and those situated beyond the Outer Ring in the suburban areas sold for 18,127 yuan per sq m.

The Chinese Academy of Social Sciences says that in the year ending in January, home prices in Shanghai rose 61.28 percent. Some of the mega cities in China have entered a "super high home price period" as median prices of homes in Beijing reached 57,568 yuan a sq m in January, followed by Shanghai at 52,429 yuan a sq m, the academy said.

The Chinese residential market started to grow quickly between 2015 and 2016, and the sales volume of the nation's residential properties rose 27.14 percent year-on-year between January and September, 20.27 percentage points higher than in 2015.

For a variety of reasons, such as the growth of incomes, Shanghai's growing importance as a global city, its expanding population and its urbanization, average home prices in Shanghai rose from 10,336 yuan per sq m a decade ago to 32,151 yuan in 2015, says James Macdonald, head of Savills China Research.

"The development of Shanghai has brought about many valuable job positions, as well as expanded the population. But because there are limited residential properties in the city center, only those wealthy enough can afford them."

Despite rising home prices, there has been no sign of sales slowing. Last year 20.2 million square meters of new homes were sold in the city, 0.5 percent more than in the previous year. At the same time 31.6 million sq m of secondhand homes changed hands, 4.2 percent more than the previous year.

Experts say prices in downtown Shanghai will continue to rise, especially since the city aspires to be a global city on a par with New York or London.

Chen Sheng, president of China Real Estate Data Academy, says the average home price in Shanghai is about $9,000 per sq m; a similar home in New York would cost $16,000 per sq m.

Chinese authorities should provide more affordable housing for people on the outskirts of the city, he says, adding that the price of a home in suburban New York can be 40 percent of the price of a home downtown. In Shanghai, however, a home in the suburbs can cost 60 percent the price of one in the downtown area.
