Commerce

Etymology

The English-language word commerce has been derived from the Latin word commercium, from com ('together') and merx ('merchandise').

Relation to business and trade

Despite many similarities (to the extent that they are sometimes used as synonyms in layman's terms and in other contexts), commerce, business and trade are distinct concepts.

Commerce and business

Commerce deals with buying, selling, and distribution of goods and services from producers to customers as well as related matters such as marketing, finance, laws, transportation, and insurance.

In a general sense, business is the activity of earning money and making one's living through engaging in commerce. The difference between business and commerce is that business can also refer to a commercial entity, such as a company. So, in a more specific sense, a business is an organization or activity for making a profit by providing goods and services which meet the needs of its customers or consumers.

Viewed in this way, commerce is a broader concept and an overall, all-encompassing aspect of business. Although business enterprises are the principal actors engaging in commercial dealings, commerce refers to the entire system of transactions through which economic resources are exchanged. It provides the underlying large-scale transactional environment comprising all kinds of exchanges within which individual business organizations operate to generate profits.

Commerce and trade

Commerce is also distinguishable from trade. By its very nature, trade is fundamentally a mutually beneficial relationship involving the swapping of goods or services between two parties, where products are usually provided in return for money. Trade is the transaction (buying and selling) of goods and services that aims to generate profit for the seller and satisfies the want or need of the buyer. When trade is carried out within a country, it is called home or domestic trade, which can be wholesale or retail. A wholesaler buys from the producer in bulk and sells to the retailer who then sells again to the final consumer in smaller quantities. Trade between a country and the rest of the world is called foreign or international trade, which consists of import trade and export trade, both being wholesale in general.

Commerce comprises not only trade, as defined above, but also auxiliary services, or aids to trade, and various procedures designed to facilitate trade. Auxiliary services such as transportation, communication, warehousing, insurance, banking services including access to credit and important financial systems, ancillary activities such as funding technological research, and packaging and making use of services offered by commercial agents such as law firms and property brokerages. In other words, commerce describes the wide, dynamic range of political, economic, technological, logistical, legal, regulatory, social, and cultural aspects of trade in abstract terms, rather than as an assemblage of particular enterprises and actors.

Described in this manner, trade is a part of commerce and commerce is an aspect of business.

Education

Commerce is offered as an interdisciplinary academic field, particularly in Commonwealth countries. Modern commerce programmes adopt a multidisciplinary approach to provide a comprehensive education in commercial activities. Such programmes typically encompass areas such as economics, finance, accounting, marketing, business analytics, supply chain, management and related fields. They reflect the broad scope of commerce, extending beyond the conventional exchange of goods and services, and prepare graduates for diverse careers in commerce and related professional fields.

A Bachelor of Commerce (BCom or B Com) is an undergraduate degree in commerce, accounting, mathematics, economics, finance and management-related subjects. It is mainly offered in Commonwealth nations. The degree is designed to provide students with a wide range of managerial skills, while also building competence in a particular area of business. The Honours Bachelor of Commerce (BComm (Hons) or HBCom) may consist of a four-year program or of a one-year postgraduate program.

A Master of Commerce (MCom or M Com) is a postgraduate Masters degree. Its curriculum is generally concentrated on one subject area and emphasizes underlying theory, including a thesis component. Although variants in general management are offered, the degree's structure and focus distinguish it from broader business degrees, such as the MBA.

The Doctor of Commerce (DCom) degree is offered in New Zealand and in South Africa both as a higher doctorate, and as a research doctorate. The higher doctorate is awarded for published work of the candidate, demonstrating original contributions of "special excellence" in some branch of commerce; the candidate will be a graduate of the university in question. The research doctorate is largely comparable to a PhD in management.

History

Ancient commerce

Prehistoric trade and ancient Egypt

Commerce existed before written history. Archaeological finds of ornaments and weapons far from their places of origin show that prehistoric peoples engaged in exchange. Historian Peter Watson and Ramesh Manickam date the earliest long-distance exchange of goods to about 150,000 years ago. The earliest written records came from ancient Egypt, where an advanced civilization had developed by about 3000 BC. Egypt remained primarily an agricultural country. Commerce was limited because the Nile Valley was geographically uniform, leaving little need for internal exchange, while surrounding deserts and the sea hindered foreign trade.

Commerce expanded during the New Kingdom (from about 1600 BC), when caravan routes linked Egypt with Phoenicia, Syria, and the Red Sea region. Egypt imported spices, ivory, gold, wine, and oil, and exported grain, linen, and manufactured goods. Trade relied mainly on barter, and many imports came as tribute. In the last centuries before Alexander the Great's conquest of Egypt, the government encouraged commerce and Greek merchants came to Egypt in considerable numbers. Around 600 BC, Necho II reportedly sent Phoenician sailors to circumnavigate Africa and began construction of a canal linking the Nile and the Red Sea.

Mesopotamia and the Persian empires

While an advanced but relatively isolated civilization was developing in ancient Egypt, the Mesopotamian river valleys of the Tigris and Euphrates emerged as another early centre of commerce. Although rich in agricultural products, the region lacked many raw materials and, unlike Egypt, was more accessible to neighbouring lands. By about 3000 BC, Babylon had emerged as a major trading centre, exchanging grain, wool, precious metals, and building materials with Arabia, Syria, and Iran. Under the Assyrian and later the Persian Empire, political unity and internal security facilitated commerce across much of the Near East. Merchants could trade under a single authority until Alexander the Great conquered the Persian Empire in 330 BC.

Phoenicia

Although commerce developed in Egypt and Mesopotamia, agriculture remained the dominant economic activity. By contrast, the Phoenicians, an ancient Semitic people who inhabited a narrow coastal strip along the eastern Mediterranean Sea, were the first people of antiquity whose prosperity depended primarily on commerce. Their limited natural resources encouraged trade. Using imported raw materials, the Phoenicians manufactured cloth, glass, metalware, and the highly prized Tyrian purple dye for export. They pioneered regular long-distance maritime trade, establishing extensive sea routes by about 1500 BC. They advanced shipbuilding and navigation throughout the ancient Mediterranean.

The Phoenicians gradually expanded their maritime trade from the eastern Mediterranean across the entire Mediterranean and into the Atlantic Ocean. They transported scarce commodities such as tin from Britain, copper from Cyprus and Spain, silver from Spain, and gold and ivory from Africa. To secure these trade networks, they established colonies and trading stations throughout the Mediterranean, including Gades and Carthage. After Phoenician influence declined, Carthage inherited much of its commercial network and became the dominant trading power in the western Mediterranean.

Ancient Greece

The geography of ancient Greece, with its indented coastline, numerous islands, and natural harbours, favoured the development of maritime trade, while shortages of grain encouraged overseas commerce. Between about 1000 and 600 BC, Greek colonies established trading networks across the Aegean Sea, Black Sea, southern Italy, and the western Mediterranean, gradually displacing the Phoenicians as the leading merchants of the Mediterranean. Domestic industries and exports developed alongside this commercial expansion. During the fifth century BC, Athens and its port of Piraeus became the principal commercial centre of the Greek world under a generally open commercial policy, importing grain and raw materials while exporting silver, pottery, and other manufactured goods. The conquests of Alexander the Great integrated markets across the eastern Mediterranean and western Asia, shifting commercial leadership from Greece to new Hellenistic cities such as Alexandria, Seleucia, and Antioch, while Rhodes emerged as a major centre of commerce, maritime law, and the suppression of piracy.

Ancient Rome

Unlike the earlier Greek commercial centres, Rome was not primarily a trading city. Its power rested on political and military organization rather than commerce, drawing food, taxes, and tribute from its provinces while exporting relatively little. Nevertheless, the Pax Romana created centuries of political stability that encouraged commerce across the empire. In the East, established centres such as Alexandria and Antioch continued to flourish, and trade expanded with regions as distant as India and China. Carthage also remained an important outlet for African trade.

Roman rule introduced roads, cities, and administrative order to western Europe, laying some foundations for economic development. However, commerce remained limited because most of the population relied on subsistence agriculture and local exchange. From the third century AD, the weakening of Roman authority brought political instability, piracy, and deteriorating infrastructure, contributing to the decline of commerce in western Europe and the transition to the Early Middle Ages.

Indian Ocean trade

While Mediterranean commerce developed around Egypt, Phoenicia, Greece, and Rome, the Austronesian peoples of Maritime Southeast Asia established an extensive Indian Ocean maritime trade network by at least 3000 BC, linking East Asia, South Asia, and eventually East Africa and the Arabian Peninsula. They exchanged technologies such as outrigger boats and catamarans, along with crops and spices including coconuts, bananas, sugarcane, cloves, and nutmeg. The network also helped connect the material cultures of India and China. By the first half of the first millennium AD, it had expanded as far as Madagascar, contributing to its Austronesian settlement, and later formed part of the broader Maritime Silk Road.

Silk road in ancient times

While maritime commerce connected the Mediterranean and Indian Ocean worlds, overland trade across Central Asia also expanded during antiquity. The Silk Road is the modern name for a network of ancient overland trade routes, named after the Chinese silk traded along them. It assumed a more organized form during the Han dynasty following the missions of Zhang Qian and Chinese expansion into Central Asia around 130 BC. These routes linked China with the Parthian Empire and ultimately the Mediterranean world. During the Roman Empire, the Silk Road became the principal overland trade network connecting East Asia with the Mediterranean. Chinese silk, spices, precious stones, glassware, and other luxury goods were exchanged through intermediary merchants (notably the Sogdians in late antiquity), and diplomatic and cultural contacts also increased between China, Central Asia, India, the Middle East, and the Roman world. Although no single state controlled the entire route, successive empires secured different sections, facilitating one of antiquity's most extensive networks of commercial and cultural exchange.

Commerce in the ancient Americas

Long-distance exchange networks connected distant regions of the Americas before European contact. Obsidian, marine shells, copper, mica and jadeite travelled hundreds of kilometres through these networks. In Mesoamerica, long-distance exchange was established by the Formative stage (2000 BC to 250 AD). During the Classic period, Teotihuacan became a major centre of production and distribution, with state-controlled procurement of obsidian from the Sierra de las Navajas and associated workshops. In North America, the Poverty Point network brought raw materials from sources hundreds of kilometres away, while the later Hopewell tradition connected communities across eastern North America, with exotic materials such as copper, mica, obsidian and marine shells transported from distant regions. In the Andes, exchange networks linked coastal, highland and lowland regions, including through the movement of Spondylus shells between Ecuador and Peru, while llama caravans facilitated interregional trade across contrasting ecological zones.

Currency and coinage

As commerce expanded across the ancient world, barter became increasingly inefficient for long-distance trade. This led to the introduction of standardized currency to facilitate the exchange of goods and services. Although barter and commodity money remained common, the first manufactured coins appeared independently in India, China, and the cities around the Aegean Sea during the 7th century BC. The earliest modern-styled coinage is generally traced to the kingdom of Lydia in Asia Minor, where standardized gold, silver, and electrum coins spread throughout the Greek world and later the Persian Empire. Coinage spread rapidly across the Mediterranean, becoming widely adopted by the Greek city-states and later by the Persian and Roman empires. Standardized coins simplified commercial exchange, facilitated taxation, and supported the expansion of long-distance trade throughout antiquity.

Medieval commerce

Early medieval commerce in Europe

Following the collapse of the Western Roman Empire, political fragmentation under the feudal system, deteriorating infrastructure, and widespread insecurity severely restricted commerce in western Europe. Trade was largely confined to government-authorized markets, where transactions could be supervised and protected. Around the year 1000, the economy was dominated by largely self-sufficient manorial villages, leaving long-distance trade mostly limited to luxury goods such as wine, spices, and furs, together with a few essential commodities carried by merchants travelling under hazardous conditions.

Commerce was a costly endeavor in the antiquities because of the risky nature of transportation, which restricted it to local markets. Commerce then expanded along with the improvement of transportation systems over time. In the Middle Ages, long-distance and large-scale commerce was still limited within continents. Banking systems developed in medieval Europe, facilitating financial transactions across national boundaries. Markets became a feature of town life, and were regulated by town authorities. With the advent of the Age of Discovery and oceangoing ships, commerce took an international, trans-continental stature.

Currently, the reliability of international trans-oceanic shipping and mailing systems and the facility of the Internet has made commerce possible between cities, regions and countries situated anywhere in the world. In the 21st century, Internet-based electronic commerce (where financial information is transferred over Internet), and its subcategories such as wireless mobile commerce and social network-based social commerce have been and continue to get adopted widely.

Transaction participants

The main participants in commercial transactions are buyers and sellers, while intermediaries connect them. Banks and financial institutions support financing and payments, insurance help manage risks, logistics providers support trading operations, and regulatory bodies establish the legal framework for commercial dealings.

Commercial transactions are commonly classified according to the types of participants involved and the relationships between them. Although these participant classifications are widely used in electronic commerce and e-business, they apply equally to traditional commerce and are independent of the medium through which a transaction takes place.

Business-to-business (B2B)

Business-to-business (B2B) transactions occur between businesses, such as manufacturers, wholesalers, distributors, retailers, or service providers. B2B commerce often involves larger transaction values, longer-term commercial relationships, negotiated pricing, and specialized goods or services.

Business-to-consumer (B2C)

Business-to-consumer (B2C) or direct-to-consumer transactions involve businesses selling goods or services directly to individual consumers for personal use. Retail trade, whether conducted through physical stores or electronic commerce platforms, represents the most common form of B2C commerce.

Consumer-to-consumer (C2C)

Consumer-to-consumer or customer-to-customer (C2C) transactions occur directly between individual consumers, typically through intermediary marketplaces or online platforms that facilitate the exchange of goods and services.

Consumer-to-business (C2B)

Consumer-to-business (C2B) transactions involve individuals supplying goods or services to businesses. Examples include freelance professional services, user-generated content, crowdsourcing, and licensing arrangements through which individuals provide value to commercial organizations.

Business-to-government (B2G)

Business-to-government (B2G) transactions involve businesses supplying goods or services to government agencies and other public-sector organizations. Such transactions commonly occur through public procurement, government contracts, and competitive tendering processes.

Government-to-business (G2B)

Government-to-business (G2B) transactions involve governments providing licensing, regulatory, taxation, customs, and other administrative or information services to businesses. Increasingly, these services are delivered through digital government platforms that facilitate regulatory compliance and commercial activity.

Other participant classifications

Other participant classifications include government-to-consumer (G2C), consumer-to-government (C2G), and government-to-government (G2G). These interactions primarily relate to the delivery of public services, government administration, and intergovernmental cooperation rather than commercial transactions, and are therefore less commonly treated as forms of commerce.

Regulation

Legislative bodies and ministries or ministerial departments of commerce regulate, promote and manage domestic and foreign commercial activities within a country. International commerce can be regulated by bilateral treaties between countries. After the second world war and the rise of free trade among nations, multilateral arrangements such as the GATT and later the World Trade Organization became the principal systems regulating global commerce. The International Chamber of Commerce (ICC) is another important organization which sets rules and resolves disputes in international commerce.

Where national government bodies undertake commercial activity with or inside other states, this commercial activity may fall outside the protection of the international rules which govern legal relationships between independent states: see, for example, the "commercial activity exception" applicable under the United States' Foreign Sovereign Immunities Act of 1976.
