Over the past 70 years, the definition of "regional style" in the study of Shang bronzes has been used in contrast to China's so-called "Central Plains (Chung-yuan)" style. The appearance of regional characteristics was first employed to indicate the "period style" of the work to one that represented a contrast to the "metropolitan style." Correspondingly, the areas outside of the Central Plains have, in definition, gone from being described as "imports from the Central Plains" to gradually become recognized for their own unique "regional features." As a result, we see how the methodology of modern studies on Shang bronzes has developed from the idea of a "single center" to one with "multiple centers." These two trends have led to various results. The first one is that there has been an imbalance in the archaeological and research work on bronzes from different areas. The second is that the periodization of each area has been noted with differing accuracy. This, first, makes it difficult to determine if an area that yields bronzes is a single center or part of one with multiple centers. Second, if it is determined to be the latter, was it originally a single center that became multiple, or was it multiple and developed unevenly? Third is the question of transmission and influence or whether bronze casting developed on its own. Fourth is the question of whether it was an open or closed space. And, fifth, if there was exchange and influence, is the issue of whether if it was mutual or oneway. Of course, these extremes allow for a wide range of possibilities in between. At present, the study of Shang regional bronzes has mostly focused on individual areas. Such studies have progressed from the question of chronology to the systems under which the bronzes were produced, as well as from focusing on features of style to the status of those who used them. When the bronzes of an area are studied, they are compared with others. Afterwards, differences are noted in order to determine their unique features. Similarities between two may suggest that some sort of "cultural relationship" existed. Then the questions of transmission and influence can be studied at greater depths to determine if the similarities reflect independent features or influences from external sources. Thus, new directions are being constantly opened for the pursuit of scholars in the field of regional bronzes.
