The global economic crisis has had little impact on Beijing's central business district (CBD), but limited space in the financial hub is hampering development, said officials.
Currently, 80 percent of office space in the CBD's 77 buildings is rented out and more than 90 percent of space in high-end buildings - including China World Trade Center and Fortune Plaza - is occupied, said Liu Chuncheng, executive deputy director of Beijing CBD Administration Committee.
Liu added that rents had not fallen in the CBD, which occupies 3.99 sq km near the city's East 3rd Ring Road.
The area is home to much of the city's finance, media and business services sector and was established by the government eight years ago.
Some reports pointed out that multinational companies, including Kodak and Motorola, had moved out in apparent cost-cutting measures with experts predicting the area's vacancy rate would rise to 40 percent this year.
However, Liu said the reports were inaccurate.
