Ricardo is one of the most outstanding representatives of classical political economy and a master of British classical political economy. David? David ricardo (1772 April18-1823 September 1 1), a classical economist, was born in Britain and graduated from business school netherlands. He completed the classical economic theory and was the last representative of the classical school.

He was a stockbroker in the early days of the exchange. Later, influenced by Adam Smith's The Wealth of Nations, he began to study economic issues, mainly including money, prices and taxes. 1September, 823 1 1 day, Ricardo, who was 5 1 year old, died of ear infection. Ricardo started from bentham's utilitarianism and established a theoretical system based on labor theory of value and centered on distribution theory. He inherited the scientific factors in Smith's theory, adhered to the principle that the commodity value was determined by the labor consumed in production, and criticized the mistakes in Smith's value theory. He pointed out that labor that determines value is socially necessary labor, and the value of goods is determined not only by living labor, but also by labor that puts into production materials. He believes that all values are produced by labor and distributed among three classes: wages are determined by the value of workers' necessary means of subsistence, profits are the balance above wages, and land rent is the balance above wages and profits. This explains the opposition between wages and profits, profits and land rent, thus actually revealing the opposition between proletariat and bourgeoisie, bourgeoisie and landlord class. He also discussed the law of currency circulation and the theory of comparative cost in foreign trade. However, he regards the capitalist system as eternal, only pays attention to the quantitative relationship in the economic category, and has metaphysical defects in methodology, so he can't explain the exchange of capital and labor and the equal profit of equal capital on the basis of the law of value. These two problems eventually led to the disintegration of Ricardo's theoretical system. His theory reached its peak within the scope of the bourgeoisie and had a great influence on later economic thoughts.
