Is a merger between Hong Kong and Shenzhen a feasible proposition?

According to the China Institute of City Competitiveness Report 2006, Hong Kong was overall the most competitive city in the country in economy, society, environment and culture.

Hong Kong notched up the top position five years in a row since the report was first released in 2001.

However, in terms of a "city's growth competitiveness" which calculates a city's economic growth, Hong Kong came fourth after Shenzhen, Macao and Beijing. The result has triggered concern that Hong Kong, faced with stiff competition, may lose its edge to mainland cities.
