The Global Market Group, a China based business service provider, conducted a recent survey in which it found that the average "life expectancy" of Chinese manufacturing enterprises is 11.1 years, while only 7.9 percent last more than 20 years.
From a sample of over 1,000 manufacturers in the Pearl River Delta and the Yangtze River Delta region, the survey found that very few enterprises have lived as long as 30 years. Most of those had Taiwan or Hong Kong investors. About 45 percent of those surveyed had been in existence less than 10 years.
