在傳世或出土文物中，人們發現新莽時期的文物相當精緻，戴熙稱王莽為古今第一鑄泉手，王國維譽新莽嘉量為曠世瑰寶，始建國銅鏡也受到清代金石學家高度關注。而在近六十年考古發掘的漢墓中，更多王莽時期的器物出土，可以看出在器物的設計與鑄造上頗費心力，因此本文嘗試探討新莽時期的度量衡器、銅鏡、錢幣的外型、圖案、品類、質地，呈現出哪些意涵，並嘗試解釋王莽為什麼要投擲心力於制器，進而闡述王莽時期鑄造器物的觀念與行為，有別於周朝「器以藏禮」的文化，而展現「器以象道」的新型態。

From the artifacts handed down or unearthed, it can be observed that artifacts in Wang Mang’s period were very delicate. Dai Xi ( 戴熙) titled Wang Mang ( 王 莽) the first currency designer of all time. Wang Guo-Wei ( 王國維) praised the Measure of the Xin Dynasty (《新莽嘉量》) as an immortal treasure. Bronze-stone scholars in the Qing Dynasty also studied the bronze mirrors in the Xin dynasty. In the past 60 years of archaeological excavation, lots of Xin objects were unearthed from ancient Han dynasty tombs. These objects show the hard work in their design and manufacture. This paper attempts to explore the shapes, graphic designs, materials, and textures of the measures, bronze mirrors, and coins. It also explains the reason why Wang put efforts into casts and illustrates that the ideas and measures of casting in the Wang period exhibited the new style of “Dao in objects,” which differs from the “rituals in objects” culture in the Zhou Dynasty.
