【明報專訊】HONG KONG's richest person Li Ka-shing, who is turning 90 this year, will step down as chairman of CK Hutchison Holdings and CK Asset Holdings and focus on his charity foundation. Given the fact that he is a man who has built from his plastic flower factory a business empire worth more than a trillion dollars, every step he takes often has an effect on the big political and economic picture of Hong Kong. His retirement also marks the end of an era. He is the symbol of traditional capitalism that has seen Hong Kong grow into an international metropolis. However, "Out with the old, in with the new," as the saying goes. What the new era calls for is a new kind of capitalism that is oriented to people. Hong Kong's capability to reach greater heights will depend on whether the new generation of entrepreneurs can ride this new wave of development across the world.
