(A) the silver standard system and its characteristics 4: The silver standard system has not been implemented for a long time. At the beginning of the 20th century, it was mainly implemented in economically underdeveloped countries, such as India, China and Mexico. Silver coins: Yuan Longfei and China implemented the silver standard. Since the Han Dynasty, silver has gradually become the main metal currency, but it belongs to the monetary system. It was not until the late Qing Dynasty that it entered the French goods system. 19 10 in April, the monetary system code was officially promulgated, and the silver standard was implemented. It is called Daqing Silver Coin, with a weight of 7 yuan 2 cents and a purity of 900%. However, both silver and silver were used. 19 14 in April, the national monetary regulations were promulgated, which stipulated that the weight of silver coins was 4.8 cents in 6 yuan. Only silver dollars were circulated. The reform of legal tender implemented 1935, and the silver standard was abolished. (2) The reason for the short implementation time of the white silver standard system is 1, and the low value of silver is not convenient for large-scale transactions. The value of silver is unstable. Annual price changes of gold and silver in London market18601880189019001910/9301932/kloc. The devaluation of silver has seriously affected the economic interests of silver-based countries. Adverse to imported industrial products (rising prices); The overall wealth of this country has depreciated. Second, the gold and silver standard system (1 6th century-1 8th century) (1) The transition from the gold and silver standard system to the gold and silver standard system (26 pages)1cannot meet the needs of large-scale transactions. /kloc-In the mid-6th century, the British industrial revolution promoted economic growth, and large-scale transactions increased, so silver could not meet the demand. The discovery of gold deposits provides the possibility for the double standard system. Brazil discovered the sands and flooded into Europe. (2) The concept and characteristics refer to the monetary system in which gold and gold are used at the same time, and the two currencies, metallic silver, are used as local currency materials. From the middle of16-18th century, it has been widely used in emerging countries. The time of implementing the double standard system for gold coins and silver coins is Britain: 1663, the United States:1791-kloc-0/873, and France: 65438. Features: (3: 00 on page 29 of the textbook) (3) The multiple standard system is 1, and the parallel standard system (early) refers to the system in which gold and silver circulate according to the actual value of their respective monetary metals. 1663 British gold coin "Gini" and silver coin "shilling" are in circulation at the same time. 2. The laws of dual-standard countries stipulate the price comparison of two currencies. These two currencies circulate at legal parity. The United States and continental European countries adopt double parity. 1792 in the United States, the parity of gold and silver is 1: 15. 3. The limping standard system is the monetary system in the transitional period from the pluralistic standard system to the standard system. Features: Restrict the casting of silver coins. It was implemented by 1873 in America.
