This essay aims to reconceptualize the monetary regime of late Qing and modern China as a multilayer system of currencies and examine the features and logics of its operation from the 16th century to early 20th century. We argue that this system consists of a variety of silver and copper currencies, each occupying a particular layer in the structure and each satisfying a specific market demand. Analyzing the production and circulation of copper and silver currencies, we first trace their evolution from the Qing to the Republican era and demonstrate the multi-layer currency structure persisted in China across the modernizing changes that took place at the end of the 19th century. Second, using data drawn from gazetteers, this essay adopts a quantitative approach to empirically examine the mechanism and speed of interactions between the different layers of the monetary market and reveal the operational mechanism of the multi-layer system. We suggest that this multi-layer system, while bringing some efficiency loss, also constituted an effective institutional arrangement that helped to ensure the stability of the Chinese economy in tumultuous times.
