THE RESEARCH OF THE FOUR CENTER OF THE CHANGJIANG DELTA AND THE CONSTRUCTION OF METROPOLITAN SHANGHAI SURROUNDING AREA
认为上海建设国际金融、贸易、航运中心需苏浙沪共建，长三角应是多中心格局，大都市圈边界应依据经济联系而非地理距离，并纳入重要经济城市。
The article thinks the strategic aim of establishing international economic, financial, trade and shipping center put forward by Shanghai should be jointly constructed by Jiangsu,Zhejiang and Shanghai. The Changjiang Delta should be Multi-Poles, rather than the general understanding of sole of Shanghai. The frontier of Metropolitan Shanghai Surrounding Area should be recognized from the economic position and the degree of economic relationship to Shanghai, rather than from the geography and transportation only. Some city with important economic status should be included into the Metropolitan Shanghai Surrounding Area, though relatively far to Shanghai. It should also promote the competition and cooperation relationship among the clusters located in Changjiang Delta.
