The aim of this paper is to provide a critique on the economic reformation practiced during the era of Emperor Wu of the Han, which is primarily based on the description in the "Treatise on the Balanced Standard" of The Records of the Grand Historian. This paper consists of three topics; the introduction is to shed light on the transformation of the policy of "producing revenue "throughout the dynasties before Emperor Wu. Furthermore, the main body focuses on discussing the motivation and condition of Emperor Wu trying to "produce revenue" on the one hand, and analyzing its policies in detail on the other hand. This paper is also a comparative study which compares the economic proposition of Sima Qian to that of Emperor Wu so that points out the impact of economic reformation of Emperor Wu on economics, politics, and society as a whole. This paper found that the primary economic policies of Emperor Wu consist of five issues: the changes in currency, the levy on wealth and the confiscation of concealed property, the salt and iron monopolies, the system of balanced standard and equitable transport, and the system of sale of honorary ranks. Moreover, on account of the exhaustion of treasuries, which resulted from the chaos and social upheavals brought about by constant wars, Emperor Wu tried to increase revenue by means of economic reformation that was particularly used to suppress the great landholders and governors or prime ministers who were conniving for their own profit.
