BEIJING, Aug 25 (Reuters) - Huge investment for the Olympics will cement Beijing's place as a world-class city and business centre, and leave a legacy of improvements for its residents.

Unlike Athens and some other past host cities, where the Games led to a mountain of debt and many of the venues now sit unused, Beijing and the Chinese government can comfortably afford the roughly $40 billion they have spent on the Games.

More importantly, less than a quarter of that bill has gone on purpose-built venues such as the Bird's Nest stadium. The rest has been spent on infrastructure such as new subway lines and projects like upgrading buses and boilers to cleaner technology.

"Many of the changes were necessary for Beijing's continued, brisk development, and the Olympics served to substantially accelerate their implementation," said Denis Ma, associate director of research in the Beijing office of property consultants Jones Lang LaSalle.

Ma pointed to the transformation the ever-expanding subway lines will bring about, as they help reduce vehicle emissions and allow the development of residential hubs in the suburbs.

Jing Ulrich, chairman of China equities at JPMorgan Securities, noted a range of other benefits that would help with the city's long-term development.

"With an improved transport system, financial services infrastructure, communications network and hospitality industry, post-Olympics Beijing will be better positioned to fulfil its potential as a world-class metropolis," Ulrich said in a report.

The state-of-the-art venues are also a legacy in themselves.

The new operators of the Bird's Nest, a consortium led by state investment group CITIC, plan to sell naming rights and make it home to one of Beijing's professional soccer clubs, building a complex of hotels, restaurants and shops around it.
