Hong Kong's traditional roles in logistics and transport are being replaced by Guangzhou and Shenzhen, a university professor said yesterday. Feng Xiao-ping, of Jinan University's Economics Institute, said Hong Kong's advantages could be enhanced in the pan-Pearl River Delta area, but at the same time the city had to develop its new economic role in this region. Professor Feng was attending a forum on the 11th five-year plan, held by the Democratic Alliance for the Betterment and Progress of Hong Kong. 'The eastern side of the delta links with Taiwan and the western side ... with the Association of Southeast Asian Nations [Asean]. Hong Kong's advantages can be enlarged through co-operation with provinces in the pan-Pearl River Delta,' Professor Feng said. She has carried out a research project for the DAB on the prospects, problems and strategies of enhancing Hong Kong's role in the delta region. She warned that Guangdong had developed rapidly with a well established traffic network, and Guangzhou and Shenzhen had become the transport hubs of southern China over the past five years. The research report suggests that Hong Kong can co-operate with Hainan, Guangxi, Yunnan and Sichuan to develop the southwestern provinces' natural and tourism resources, and foster links with Asean. Li Huiwu, deputy director of the Guangdong provincial government's development research centre, said: 'Hong Kong should focus on its air transport and shipment of high-value goods, such as electronic products.'
