In the areas of economics and finance，various objective indicators show that Hong Kong has developed greatly following the territory's return to Chinese sovereignty.However，at the same time，the general public has been growing increasingly discontented with the government and society.Drawing on both objective and subjective data，an attempt is made in this paper to explain the transformation of Hong Kong's economy and society after the Hong Kong handover.Also discussed are the core problems of the high degree of monopolization of the economy and resources，and the integration between Hong Kong and Mainland China may have reached the optimal level.As such，ordinary people may have the sense that they are unable to share the fruits of economic development，but to bear bigger costs arising from the process of integration.This has led to dissatisfaction and resentment in many areas，which could potentially have an extremely negative impact on the implementation of “One Country，Two Systems”.
