The Foundations of Economic Specialization in Early China

The Shang Dynasty (c. 1600–1046 BCE) witnessed a transformative phase in China’s economic history, where deepening social divisions of labor laid the groundwork for sophisticated trade networks. As archaeological evidence reveals, this was not merely a story of surplus production but of intentional specialization—craftsmen and settlements increasingly focused on specific goods destined for exchange rather than local consumption.

At Zhengzhou’s Minggong Road pottery workshop, excavations uncovered a striking pattern: over 80% of damaged ceramics were standardized cooking vessels like pen (basins) and zeng (steamers), with almost no trace of sand-tempered ware like li tripods. Nearby burial site H21 mirrored this find, yielding perfectly reconstructible pots where 80% were basins and 20% steamers. Such monotony in production signals targeted manufacturing for trade, not domestic use.

Assembly Lines of Antiquity: Bronze and Craft Production

Metalworkers mirrored this specialization. The Nanguanwai bronze-casting site primarily produced tools and weapons (spearheads, arrows, knives), while Zijing Mountain’s workshop focused exclusively on knives and arrowheads. By the Late Shang period, entire settlements became hubs for specific industries—from Anyang’s ritual bronze workshops at Miaopu North to Xiaomintun’s weapon forges, and from Dasikong Village’s bone-carving ateliers to Zhao Yao’s stone tool factories.

This partitioning of labor extended beyond individual crafts. The Late Shang political economy developed a core-periphery model, with the capital Yinxu (modern Anyang) as the apex of a four-tiered settlement hierarchy: royal capital, regional centers, mid-sized towns, and villages. Resources flowed unevenly through this network, concentrating luxury goods and strategic materials (jade, bronze, turtle shells) toward elite centers.

Silk Roads Before Silk: Long-Distance Trade Networks

Yinxu’s material culture tells a globe-spanning story:
– Bronze ingredients: Copper likely from the Yangtze Delta, tin/lead possibly from Yunnan or Hunan
– Sacred minerals: Jade transported 3,000 km from Khotan (Xinjiang)
– Exotic currencies: Cowrie shells from the South China Sea
– Ritual objects: Sea turtle plastrons and even whale bones

While some goods arrived through tribute or raids (the Shang military reached only ~500 km south), most distant materials—especially bulk items like tin—required established trade routes. Oracle bones mention “tribute of shells from the Qiang people,” suggesting negotiated exchanges with western tribes.

From Barter to Bullion: The Monetization of Exchange

Two parallel systems facilitated trade:
1. Barter: Grain, pottery, and tools exchanged locally
2. Monetary trade: Cowrie shells as proto-currency

The Shang’s cowrie economy left extensive traces:
– Oracle records: “On Gengxu day, divined: grant women many peng of shells” (Heji 11438)
– Bronze inscriptions: Over 20 vessels commemorate shell gifts, like the 7th-year ritual ding: “King gave Yayu shells to cast for Ancestor Gui”
– Burial customs: Shells placed in mouths (symbolizing sustenance) or hands (wealth). Elite tombs contained thousands—Lady Hao’s burial held 6,800.

Standardized Cypraea moneta shells (1.8–2 cm, perforated) dominated, supplemented by rare copper/stone imitations. The monetary unit peng (likely 10 shells) appears in royal gifts: “King rewarded Shusizi with 20 peng” (Ding vessel inscription).

The Cowrie Standard: Economic and Social Impacts

This monetary system catalyzed social changes:
– Wealth display: Shell hoards marked elite status
– Interregional trust: Standardized value enabled long-range trade
– Craft acceleration: Specialized workshops could “sell” output for universal currency

Notably, the Shangshu documents officials hoarding “shells and jade,” while oracle bones show shells purchasing everything from livestock to military conscripts.

Legacy of the First Chinese Economy

The Shang’s commercial innovations established patterns lasting millennia:
– Urban specialization: Later dynasties replicated craft-district models
– Monetary traditions: Cowries influenced early coinage (spade/bridge money)
– Trade routes: Shang networks became the backbone of Zhou dynasty “royal highways”

Modern archaeology continues revealing surprises—2019 finds of Shang-era cowries in Sichuan suggest trade reaching beyond the Central Plains. These silent shells, once currency for a Bronze Age superpower, remind us how deeply China’s economic DNA was forged in the fires of specialization and exchange.
