In the previous section, the idea was simple: markets appeared after humans learned farming and animal husbandry around 8,000 to 10,000 years ago. Once food production created surpluses, different groups found themselves with different harvests and resources. To improve daily life, they began exchanging what they had. That was the birth of the market.

At first, a market did not need much. A flat, easy-to-find open space with good visibility was enough, and most of the trading centered on food. But as human productivity kept improving, the range of things people could make also increased. The need to exchange those goods grew with it, and markets developed accordingly.

China, as one of the world’s four ancient civilizations and one with an especially long and continuous historical development, offers a very representative example of how markets changed over time.

Markets in Remote Antiquity

About 8,000 years ago, humans learned to make pottery. Clay mixed with sand and gravel was shaped by hand into a rough form and then fired over a bonfire. Because the heat of an open fire could only reach around 800 to 900°C, the earliest pottery was fragile and broke easily.

Roughly 5,000 years ago, pottery making improved further. People developed painted and glazed pottery, with early white and green glazes appearing. Production methods also advanced: instead of shaping vessels entirely by hand, people began using a wooden wheel. That made it possible to create more elegant forms. Firing temperatures could now exceed 1,200°C, so pottery became not only more beautiful but also much stronger and more durable.

This transformation mattered for trade. Pottery was no longer just a practical container. It gradually acquired aesthetic value as well. It could be used, displayed, and appreciated, which made it even more suitable for exchange.

Another major invention from roughly the same broad era was bronze. Bronze tools and vessels greatly advanced productive capacity and also helped push culture forward. Woodwork, stonework, and jade craftsmanship also progressed during this period. Human material civilization made enormous gains.

As productivity increased, human society also changed. Earlier kin-based organization gave way to tribal society. More people gathered together, and labor began to divide: some focused on farming, some on raising animals, and others on handicrafts such as pottery making or bronze casting. This was humanity’s earliest division of labor, and one of the most important steps in social evolution.

Once people could produce more kinds of goods, and produce them faster, there was more to exchange with other tribes. That required larger markets and more frequent trading.

The Chinese word for “market” is especially revealing. Today it looks like a single word, but in older usage it carries two linked meanings. One part refers to a bazaar or street market with buildings and a fixed trading site. The other refers simply to a broad, flat open area. Such a place needed no permanent structures—only the removal of obstacles like large stones, dirt mounds, or trees.

Strictly speaking, the earliest markets belonged to that second type: an open ground where people regularly came together to exchange goods.

That may sound disappointingly primitive. But human civilization did not stand still, and neither did markets.

Even though these earliest markets were simple, old writings describe them with remarkable poetic force: at midday people gathered to trade, bringing together people from all directions and goods from all places, then departing after exchange, each with what they needed. The passage is associated with the ancient story of Shennong establishing a marketplace.

That contrast—between the rough reality of an open field and the beautiful language used to describe it—suggests two lessons.

First, the value of anything has to be judged within the conditions of its own time. It makes little sense to measure the past only by present standards.

Second, people looking at the same thing from different angles often reach different conclusions. Choosing a perspective that allows us to see more of the good in the world can make life feel richer.

The Rise of Ancient Urban Markets

About 4,000 years ago, the Xia dynasty, traditionally regarded as China’s first slave-state dynasty, emerged. With the appearance of the state and powerful slave owners, handicrafts separated further from agriculture. Social productivity advanced again, labor efficiency improved, and material life became more abundant.

At this stage, people were exchanging far more than food and pottery. Trade now included clothing, ornaments, plows and other tools, as well as animals such as horses and cattle. An open field was no longer enough for so many goods. That was when the more developed form of the market appeared: not just a broad square, but also shops and fixed trading spaces.

As markets became established, trade grew more frequent. Ordinary people, however, could usually only trade nearby and had limited ability to travel long distances. This created a new profession: merchants, people who specialized in buying and selling.

The rise of merchants made markets far more dynamic. People could buy things they had never seen before, and local goods could be sold to places much farther away. But frequent trade also exposed a problem: barter was inconvenient. Out of this came the general equivalent—money, or in simpler terms, something functioning as “cash.” The emergence of merchants and money greatly promoted commerce and strongly supported the economy of slave society.

The Era of Large Wards and Organized City Markets

About 2,200 years ago, the Qin dynasty established China’s first unified empire. Political unification made commerce easier, and market scale expanded beyond what had existed before.

The image above represents Chang’an in the Tang dynasty around 1,400 years ago. At that time, the city—today’s Xi’an—was divided into 108 wards. Each ward contained residential areas, commercial areas, administrative personnel, and ward gates. You can think of one ward as something like a highly organized neighborhood district.

The whole city had 108 wards and a population of over a million. Its widest avenue, Zhuque Avenue, reached 155 meters across—an astonishing width even by modern standards.

Compared with earlier markets, the large ward-market system had two especially important features.

The first was the shift from itinerant merchants to sedentary merchants. Instead of moving from place to place, many traders opened shops and waited for customers.

The second was a much clearer functional division inside the market. One area specialized in clothing and jewelry, while another focused on mules, horses, and similar goods. In other words, specialized markets had appeared.

These changes brought obvious advantages. Specialized markets made it easier for buyers to compare options and choose goods with better quality and price. At the same time, fixed-location merchants were more stable and easier to monitor, which reduced fraud.

Modern and Contemporary Markets

Once humanity entered industrial civilization, material production became much more advanced, and expectations for markets rose with it.

What is industrial civilization in this context? It means using machines such as steam engines and electric motors to replace human labor and animal power. Because machines were far stronger and more efficient, people could produce goods faster than before, and they could also manufacture things that earlier eras could not—trains, automobiles, textile machines, and much more. In short, machines made society wealthier.

As goods became more abundant, markets had to become larger, more specialized, and more tightly managed.

After the arrival of industrial civilization, one of the first market forms to expand was the large wholesale-style market.

These spaces could be fairly simple: a large area, sometimes with a roof but no walls, offering little more than shelter from sun and rain. Yet their role was significant. They pushed market specialization further, allowing different kinds of markets to focus on different functions and making commodity trade more professional.

Many specialized markets still exist today: produce markets, flower-and-bird-and-fish markets, and all kinds of wholesale markets.

Then there is the shopping mall.

Compared with the large open market, a mall is much more refined—bright, spacious, climate-controlled, comfortable in both winter and summer. But in one important sense, malls often move in the opposite direction from specialized wholesale markets. Most malls are comprehensive rather than narrowly specialized. Different floors sell different categories of goods, and a single building may contain nearly everything people commonly need. Of course, there are also specialized malls, such as those focused mainly on electronics or clothing.

The newest major form is the online marketplace.

Online malls emerged after the internet matured. In essence, they moved the traditional shopping center onto the web. Compared with physical malls, they usually offer a wider range of products and make comparison easier, which improves shopping efficiency.

That convenience, however, has a downside: it can make people less willing to leave home and less likely to get enough exercise.

Market forms keep changing, but the basic idea does not. As long as a place or system is used for exchange, it is a market—whether it looks like a large open market, a shopping mall, or an online store.

Why Markets Keep Changing

A market does not keep evolving for no reason. Its forms change because people’s shopping needs keep changing.

When buyers want many apple sellers gathered in one place so they can compare quality and price, a specialized fruit market appears.

When people want to buy fruit, vegetables, and everyday supplies such as storage bags in one trip, the supermarket appears.

When people want to buy things without leaving home, online shopping appears.

So although market forms vary, the purpose behind their evolution remains much the same: to make exchange more convenient, more reliable, more efficient, and lower in transaction cost.

Why Older Market Forms Still Survive

If malls and online shopping already exist, why do large markets and street stalls still remain? Why have they not been eliminated?

The answer lies in the old idea that everything has its strengths and weaknesses.

Malls may offer a better shopping experience, and online stores may offer greater variety, but neither is always as immediate and convenient as a stall just outside one’s neighborhood. Different market forms also operate with very different cost structures, and those cost differences affect what kinds of goods suit them best.

For example, low-priced but bulky products such as plush toys are well suited to low-cost channels like street stalls or large open markets. By contrast, compact and expensive products such as mobile phones are better suited to places with stronger credibility, such as shopping malls or online platforms.

For that reason, neighborhood convenience stores, street stalls, and large markets still have a practical reason to exist. Different goods, different prices, different levels of trust, and different expectations of speed all help determine which kind of market makes the most sense.
