Increasing government intervention in the private economy during the late 2nd century BC severely weakened the commercial merchant class. This allowed wealthy landowners to increase their power and to ensure the continuation of an agrarian-dominated economy. The wealthy landlords eventually dominated commercial activities as well, maintaining control over the rural peasants—upon whom the government relied for tax revenues—military manpower, and public works labor. By the 180s AD, economic and political crises had caused the Han government to become heavily decentralized, while the great landowners became increasingly independent and powerful in their communities.

At the beginning of the Eastern Han, the land tax rate was one-tenth of the crop yield, but following the stabilization following Wang Mang's death, the rate was reduced to the original one-thirtieth in 30 AD.

Towards the end of the Han dynasty, the land tax rate was reduced to one-hundredth, with lost revenue recouped by increasing the poll

After the government monopoly on liquor was abolished in 81 BC, a property tax of 2 coins for every 0.2 litre (0.0528344074568369 US gal) was levied on liquor merchants.

 existed during the Han period. These were civilian conscription (gengzu 更卒) and military conscription (zhengzu 正卒). In addition to paying their monetary and crop taxes, all peasants of the Western Han period aged between fifteen and fifty-six were required to undertake mandatory conscription duties for one month of each year. These duties were usually fulfilled by work on construction projects.

 composed of paid career soldiers.

During the Eastern Han, peasants could avoid the month of annual conscripted labor by paying a tax in commutation (gengfu 更賦). This development went hand in hand with the increasing use of hired labor by the government. In a similar manner, because the Eastern-Han government favored the military recruitment of volunteers, the mandatory military draft for peasants aged twenty-three could be avoided by paying a tax in substitution.

Merchants

There were two categories of Han merchants: those who sold goods at shops in urban markets, and the larger-scale itinerant traders who traveled between cities and to foreign countries. The small-scale urban shopkeepers were enrolled on an official register and had to pay heavy commercial taxes. Although these registered merchants were taxed, an edict of 94 AD ordered that landless peasants who had to resort to peddling were to be exempted from taxation.

Itinerant merchants were often wealthy and did not have to register. These itinerant merchants often participated in large-scale trade with powerful families and officials. Nishijima writes that most of the biographies of "wealthy men" in the Records of the Grand Historian

were those of itinerant merchants.

In contrast, registered marketplace merchants had a very low social status and were often subject to additional restrictions. Emperor Gaozu passed laws levying higher taxes, forbidding merchants from wearing silk, and barring their descendants from holding public office
Civil service

. These laws were difficult to enforce. Emperor Wu targeted both the registered and unregistered merchants with higher taxes. While registered merchants were not allowed to own land, if they broke this law their land and slaves would be confiscated. However, wealthy unregistered merchants owned large tracts of land. Emperor Wu significantly reduced the economic influence of great merchants by openly competing with them in the marketplace, where he set up government-managed shops that sold commodities collected from the merchants as property taxes.

Private manufacture and government monopolies

Iron and salt

At the beginning of the Han Dynasty, China's salt and iron enterprises were privately owned by a number of wealthy merchants and subordinate regional kings. The profits of these industries rivaled the funds of the imperial court. A successful iron or salt industrialist might have employed over a thousand peasants, causing a severe loss of agricultural tax revenue to the central government. To restrict the power of the industrialists, Emperor Wu had nationalized

Nationalization usually refers to private assets, but may also mean assets owned by lower levels of government, such as municipalities, being...

 the salt and iron industries by 117 BC.

The government also instituted a liquor monopoly in 98 BC. However, this was repealed in 81 BC in an effort to reduce government intervention in the private economy.

The Reformist Party supported privatization, opposing the Modernist Party, which had dominated politics during the reign of Emperor Wu and the subsequent regency

s rather than to be of practical use, were of inferior quality, and were too expensive for commoners to purchase. In 44 BC, the Reformists had both the salt and iron monopolies abolished, but the monopolies were reinstated in 41 BC after their abrupt closure resulted in significant losses of revenue for the government and disruption of the private economy.

Wang Mang preserved these central government monopolies. When Eastern Han began, they were once again repealed, the industries given to local commandery governments and private entrepreneurs. Emperor Zhang of Han

 (r. 75–88 AD) briefly reintroduced the central government monopolies on salt and iron from 85 to 88 AD, but abolished them in the last year of his reign. After Emperor Zhang, the Han never returned the salt and iron industries to government ownership.

Grain

The grain trade was a profitable private enterprise during the early Western Han, yet Emperor Wu's government intervened in the grain trade when it established the equable marketing system (also known as the ever-normal granary system) in 110 BC. The government purchased grain when it was plentiful and inexpensive, shipping it to granaries for storage or to areas where grain was scarce. The system was intended to eliminate grain speculation, to create a standard price and to increase government revenue. The system was designed by civil servant Sang Hongyang

 (r. 57–75). Emperor Ming also abolished the system in 68 AD, when he believed that the government's storage of grain increased prices and made wealthy landowners richer.

Ebrey argues that although most of Emperor Wu's fiscal policies were repealed during Eastern Han, their damage to the merchant class and the subsequent laissez-faire
Laissez-faire
In economics, laissez-faire describes an environment in which transactions between private parties are free from state intervention, including restrictive regulations, taxes, tariffs and enforced monopolies....

 policies of Eastern Han allowed the wealthiest landowners to dominate society, ensuring that China's economy would remain firmly agrarian-based for centuries. The Eastern Han central government lost an important source of revenue by relinquishing its salt and iron industries and purchasing its armies' swords and shields from private manufacturers. However, this loss of revenue was often compensated by higher taxes levied on the merchants.

Government workshops

Han government workshops produced common, luxury, and even artistic funerary items, such as the ceramic figurines and tomb tiles which adorned the walls of underground tombs. Imperial workshops were operated by the Minister Steward, whose ministry controlled the treasury and the emperor's private finances.

There were, of course, numerous reasons for maintaining roads. A unified political system could be maintained only as long as the government had the means of quickly dispatching officials, troops, or messengers as needed. Such a system of transportation, once established, facilitated commerce. At the local level, road and bridge projects seem to have been initiated as much for the sake of traveling merchants as for officials.

Estate management and trade

In the early Eastern Han, Emperor Ming passed laws which prohibited those involved in agriculture from simultaneously engaging in mercantile trade. These laws were largely ineffective, since wealthy landowners and landlords made significant profits from the trading of goods produced on their estates. Cui Shi (催寔) (d. 170 AD), a local commandery administrator who later served as an official in the central government's secretariat, started a winery business in his home to pay for his father's funeral.

The following table is modelled on Ebrey's "Estate and Family Management in the Later Han as Seen in the Monthly Instructions for the Four Classes of People" (1974). Ebrey writes: "… the same item was often bought and sold at different times of the year. The rationale for this is very clearly financial: items were bought when the price was low and sold when it was high." The specific amounts for each commodity traded are not listed, yet the timing of sale and purchase during the year is the most valuable information for historians. Missing from Cui Shi's list are important items which his family certainly bought and sold at specific times of the year, such as salt, iron farm tools and kitchen utensils, paper and ink (the papermaking

 both speculate that the Roman mission of 166 AD involved enterprising Roman merchants instead of actual diplomats; Hucker writes:

Tributary missions from vassal states were commonly allowed to include traders, who thus gained opportunities to do business in the capital markets. No doubt a large proportion of what the Chinese court chose to call tributary missions were in fact shrewdly organized commercial ventures by foreign merchants with no diplomatic status at all. This was unquestionably the case, most notably, with a group of traders who appeared on the south coast in 166 A.D. claiming to be envoys from the Roman emperor Marcus Aurelius Antoninus.
