Chief executive officers in Chinese companies spend fewer years in office, and have more previous experience in different companies than their international peers, according to a study released in Shanghai on Thursday.

But analysts at Booz & Company, the management and strategy consulting firm that carried out the study, said while CEOs in China could well be more experienced in facing different challenges, the high turnover may also present a risk to companies keen on developing longer-term strategies.

The poll, based on opinions gathered from 2,500 of the world's largest public companies, revealed the turnover rate of CEOs in China last year was 8.1 percent, against a global average of 15 percent.
