The Economy of Singapore is a highly developed and successful free market economy in which the state plays a major role. It has an open business environment, relatively corruption-free and transparent, stable prices, and one of the highest per capita gross domestic products (GDP) in the world. Exports, particularly in electronics and chemicals, and services provide the main source of revenue for the economy, which allows it to purchase natural resources and raw goods which it does not have. Singapore could thus be said to rely on an extended concept of entrepot trade, by purchasing raw goods and refining them for re-export, such as in the wafer fabrication industry and oil refining. Singapore also has a strategic port which makes it more competitive than many of its neighbours to carry out such entrepot activities. The Port of Singapore is the busiest in the world, surpassing Hong Kong and Shanghai. In addition, Singapore's port infrastructure and skilled workforce, which is due to the success of the country's education policy in producing skilled workers, is also fundamental in this aspect as they provide easier access to markets for both importing and exporting, and also provide the skill(s) needed to refine imports into exports.Singapore's total trade in 2000 amounted to S$373 billion, an increase of 21% from 1999. Despite its small size, Singapore is the tenth-largest trading partner of the United States. In 2000, Singapore's imports totalled $135 billion, and exports totalled $138 billion. Malaysia was Singapore's main import source, as well as its largest export market, absorbing 18% of Singapore's exports, with the United States close behind. Re-exports accounted for 43% of Singapore's total sales to other countries in 2000. Singapore's principal exports are petroleum products, food/beverages, chemicals, textile/garments, electronic components, telecommunication apparatus, transport equipment. Singapore's main imports are aircraft, crude oil and petroleum products, electronic components, radio and television receivers/parts, motor vehicles, chemicals, food/beverages, iron/steel, textile yarns/fabrics.
