At least 50,000 Taiwanese are working in Shenzhen, a southern boom city that borders Hong Kong and has nearly 4,000 Taiwanese-invested firms, reports Friday's Shenzhen Economic Daily.

These include investors, technological and managerial professionals and their families.

Shenzhen, one of major special economic zones designated by late Chinese leader Deng Xiaoping in 1980, has drawn more than 3,900 Taiwanese-invested enterprises since the first was establishedin 1982.

These companies involve an aggregate 6.2 billion US dollars of contractual investment, and their actual use of investment totals 5 billion US dollars, according to the report.

More than 700,000 employees are working for these Taiwanese-funded firms, 90 percent of which are profitable, the report says.

The municipal government of Shenzhen has opened a special office to hear Taiwanese businessmen's complaints and help them solve problems in life and at work. The office has heard more than 380 complaints over the past three years, 95 percent of which have been solved, the paper says.
