The regional coordinated development experience of world’s developedeconomiescan provide various inspirations for the development of the Guangdong-Hong Kong-Macao Greater Bay Area. This paper summarizes the development experience of metropolitan area of Tokyo in Japan，of Paris in France，of London in the United Kingdom and of Tel Aviv in Israel. This paper believes that the following practices are worth learning from the Guangdong-Hong Kong-Macao Greater Bay Area：the Tokyo metropolitan area in Japan sets quantitative assessment and monitoring standards；the Paris metropolitan area in France breaks through the spatial constraints of the old urban area to build sub-centers and satellite cities on a larger scale and collaborate with secondary and tertiary industries；The London metropolitan area is guaranteed by scientific and reasonable planning and design，efficient legislation and flexible operating mechanisms；there is also a service-oriented government in Tel Aviv，Israel，which encourages innovation and entrepreneurship and tolerates failure.
