This chapter looks at the crucial factors and discusses their possible development in the future and the possible impacts they will have on the Hong Kong economy. The financial institutions and markets of Hong Kong have contributed to China’s development in various ways, especially in the banking sector and the stock market. The integration has been mostly based on economically complementary endowments: cheap labor and land in southern China, and entrepreneurship, capital, and international market connections in Hong Kong. In terms of Hong Kong’s domestic macroeconomic policies, it is of prime importance to maintain a stable monetary environment. The contribution of Hong Kong to China with regard to external loans should include Hong Kong’s role as the center for loan syndication. As the post-war immigrants adjusted to life in Hong Kong and the post-war generation matured, the percentage of immigrants in the total population dropped. Hong Kong people as a whole have shed their immigrant mentality.
