Income from land sales in China's 10 major cities jumped 14.4 percent to 40.9 billion yuan ($6.4 billion) in August from July, statistics from the Beijing-based real estate agency Homelink showed on Wednesday. The rise was due to the quality, more than the quantity, of the land for sale, according to an analyst.

Meanwhile, floor space sold in the past month also increased by 30 percent in those cities.

"As the revenue from selling land declined, due to the rigorous government measures, local governments are more willing to launch quality land parcels into the market. Meanwhile, property developers are more aggressive in grabbing land parcels," said Chang Qing, an analyst at Homelink.

The trend will continue to September, Chang said.
