英文摘要：

The mainland of China takes “Socialism with China＇ s Characteristics”as its mainstream ideology;Hong Kong, in contrast, advocates liberalism. Both ideologies share the characteristics of being multiple and heterogeneous, with emphasis on exerting their legal functions and cultivating economic values. The main distinction on mainstream ideologies between mainland and Hong Kong lies on their different guiding thoughts, different viewpoints on their functions and effects, and different relations with other social trends of thought.
