The Chinese art market plummeted last year, with auction sales of living artists' works falling by 45 percent as slowing growth and a corruption crackdown under President Xi Jinping took their toll, a survey said Thursday.

By far the most valuable artist was ink painter Cui Ruzhuo, 72, who is known for his large-scale traditional landscapes, said wealth publisher the Hurun Report, which collated auction results for the 100 most lucrative Chinese artists.

Cui's works fetched $120.4 million, it said, far ahead of second-placed oil painter Zeng Fanzhi, who saw his sales value crash by 62 percent.

There were no figures to indicate whether the average price of individual works had decreased.

"A heady mix of the continued anti-corruption campaign, which has put a stop to gifting art to government officers, and a slowdown in the economy have combined to see both sales and the number of top works at auction pretty much halve," said Hurun Report chairman Rupert Hoogewerf.

Growth in the world's second-largest economy slowed to its weakest in a quarter of a century last year at 6.9 percent, a far cry from the double-digit boom years of the past.

Even so, greater China surpassed the US last year to become home to the largest population of billionaires in the world, Hurun said in a previous report -- indicating an increase in the pool of potential super-wealthy art collectors.

The 100 artists' auction sales totalled $56.5 billion.

Only three artists on the list were women. They included Chen Peiqiu, age 94, at number 16.

A surprising new entry was Jack Ma, CEO of internet giant Alibaba, whose inclusion came courtesy of a collaborative painting he executed with Zeng Fanzhi that sold at Sotheby's in Hong Kong for $5.3 million.

Cui was one of just eight artists who saw an increase in sales, with his revenues up 69 percent from 2014.

He made headlines last April when an eight-panelled snowy mountainscape of his sold for $30 million at Poly Auction in Hong Kong -- the highest ever by a living Asian artist.

At the same auction the year before, another of his landscapes that sold for $3.7 million was mistaken for rubbish and thrown out by cleaners, with Cui telling the Wall Street Journal: "I believe it was an accident."

Though many believe China's art market has been overheated in recent years, Cui told fellow artists that it was a national imperative to increase the value of their work.

"Our current downturn and backwardness shouldn't discourage us; we artists should unite together and for the sake of our art market and our nation walk out towards the world, hand in hand, striving ardently together," he said.

Huang Jiannan, a self-taught artist ranked seventh on Hurun's list, saw the auction value of his works drop by 45 percent last year, but he shrugged off the loss.

"These statistics measure the flow of my works in the market - it has nothing to do with me. I don't get the money from these sales directly," he told AFP.

He pointed to a Mao pin on his lapel.

"I worship Mao Zedong."

Huang's auction sales totalled $13.1 million last year, according to Hurun.

Critics such as Xie Chunyan believe that focusing on auction values is a poor judge of Chinese artists' worth:

"Just because this little British guy Hoogewerf says he wants to find a common standard to measure things 1, 2, 3 doesn't mean that this is the best method."
