The economy of the Han dynasty (206 BC – 220 AD) of ancient China experienced upward and downward movements in its economic cycle, periods of economic prosperity and decline. It is normally divided into three periods: Western Han (206 BC – 9 AD), the Xin dynasty (9–23 AD), and Eastern Han (25–220 AD). The Xin regime, established by the former regent Wang Mang, formed a brief interregnum between lengthy periods of Han rule. Following the fall of Wang Mang, the Han capital was moved eastward from Chang'an to Luoyang. In consequence, historians have named the succeeding eras Western Han and Eastern Han respectively.
The Han economy was defined by significant population growth, increasing urbanization, unprecedented growth of industry and trade, and government experimentation with nationalization. Another large component of the government is that it was run by influential families who had the most money. In this era, the levels of minting and circulation of coin currency grew significantly, forming the foundation of a stable monetary system. The Silk Road facilitated the establishment of trade and tributary exchanges with foreign countries across Eurasia, many of which were previously unknown to the people of ancient China. The imperial capitals of both Western Han (Chang'an) and Eastern Han (Luoyang) were among the largest cities in the world at the time, in both population and area. Here, government workshops manufactured furnishings for the palaces of the emperor and produced goods for the common people. The government oversaw the construction of roads and bridges, which facilitated official government business and encouraged commercial growth. Under Han rule, industrialists, wholesalers, and merchants—from minor shopkeepers to wealthy businessmen—could engage in a wide range of enterprises and trade in the domestic, public, and even military spheres.
