极化开发往往能吸引大量资本、技术、劳动力等生产要素的集聚 ,从而形成这些生产要素的“辐合流场”。但在极化开发背景下 ,也会产生社会极化现象 ,造成城市社会贫富阶层收入差异的拉大。作为中国强力开发的浦东新区 ,不仅出现了人口、人才和资本等生产要素的极化 ,而且也出现了城市不同阶层贫富收入拉大等社会极化问题。浦东新区社会极化主要是城市功能转变、生产要素集聚和经济全球化影响三个因素造成的 Polarization development often can attract a large number of capital, technology, labor and other factors of production aggregation, thus forming the “convergence flow field” of these factors of production. However, in the context of polarization development, social polarization will also occur, resulting in a widening income gap between urban poor and the rich. Pudong New Area, which was strongly developed by China, not only polarized the production factors such as population, talent and capital, but also caused social polarization problems such as the widening income gap between the poor and the rich in different sectors of the city. The social polarization in Pudong New Area is mainly caused by the changes of urban functions, the agglomeration of production factors and the impact of economic globalization
