Shenzhen Airport Co., Ltd. in south China's Guangdong Province said net profits surged 134.92 percent year on year to 575 million RMB (84 million USD) in 2009.

Business revenue was 1.66 billion RMB last year, up 9.69 percent compared to the year before. Earnings per share jumped 134.94 percent to 0.3402 RMB, the company said in a statement filed to the Shenzhen Stock Exchange Friday (March 5).

China's airports registered 486 million in passenger throughput in 2009, up 19.79 percent, according to figures released in February by the Civil Aviation Administration of China.
