'Revolving door' at firms in China

Turnover among chief executive officers in China was the highest in the world last year, and the rate of change may remain high this year as the reform of State-owned enterprises moves forward and the anti-corruption drive continues, according to a study by Strategy&.

Strategy&, a management consulting arm of PricewaterhouseCoopers LLP, surveyed the world's top 2,500 listed companies, defined by market capitalization as of Jan 1, 2014. The study included 193 companies from China.

The CEO turnover rate globally was 14.3 percent in 2014, compared with 14.2 percent in 2013. In China, the rate fell from 16.9 percent in 2013 to 15 percent in 2014.
