Metropolitan areas under different regional contexts show different development characteristics and evolution paths.Urban agglomeration of the Pearl River Delta is characterized by having multiple cores and strong connection,in which cities used to be "geographically connected before interactive with each other." And during the functional interaction,three metropolitan areas emerged in different stages with different characteristics in the Pearl River Delta.By analyzing the urbanization process of the Pearl River Delta,it shows that the interaction among cities within the three metropolitan areas has obvious characteristics.In the early stage,it was featured by the industrial expansion benefiting from infrastructure integration.And then it was shifted to the co-construction and sharing of public services based on the demand of "people." Now it is in a new stage of spatial reconstruction driven by agglomeration of service industries and innovation forces.Finally,the lessons learned from the Pearl River Delta are summarized from the aspects of transportation,mechanism,shared value,relationship,and topography.
