The territory has little arable land and few natural resources, so it imports most of its food and raw materials. Agricultural activity -- relatively unimportant to Hong Kong’s economy and contributing just 0.1% of its GDP -- primarily consists of growing premium food and flower varieties. Hong Kong is the world's eleventh largest trading entity, with the total value of imports and exports exceeding its gross domestic product. It is the world's largest re-export centre. Much of Hong Kong's exports consist of re-exports, which are products made outside of the territory, especially in mainland China, and distributed via Hong Kong. Its physical location has allowed the city to establish a transportation and logistics infrastructure that includes the world’s second busiest container port and the world’s busiest airport for international cargo. Even before the transfer of sovereignty, Hong Kong had established extensive trade and investment ties with the mainland, which now enable it to serve as a point of entry for investment flowing into the mainland. At the end of 2007, there were 3.46 million people employed full-time, with the unemployment rate averaging 4.1% for the fourth straight year of decline. Hong Kong's economy is dominated by the service sector, which accounts for over 90% of its GDP, while industry constitutes 9%. Inflation was at 2.5% in 2007. Hong Kong's largest export markets are mainland China, the United States, and Japan.
As of 2010, Hong Kong is the eighth most expensive city for expatriates, falling from fifth position in the previous year. In 2011, Hong Kong was ranked second in the Ease of Doing Business Index, behind Singapore. General principle No. 5 of the Basic Law of the SAR suggests that the CPC expects that it shall have brought the economic system of the Mainland and Hong Kong into harmony by 2047, by which time the Chinese economy is predicted to have been the largest by any measure of GDP for decades.
