明代苏州、松江、江西、浙江人“毋得任户部”这一制度包括两个方面的内容苏松江浙人不得为户部官,苏松江浙吏不得为户部吏;但前者为“祖制”,后者是“成例”,法律地位不同。“祖制”针对的首先是苏松籍官员;“成例”针对的是苏松江浙的吏员,以及作为其后备力量的“市井之徒”。“祖制”在洪武后期有所松动,并成为建文时苏松江浙人仍得官户部的依据;永乐初对建文改制的全盘否定,以及由周忱戴衔户部而发生的变故,遂使“祖制”二百年不变。通过扼制“南人”特别是江南经济发达地区的士人,以缩小南北之间的政治、经济、文化差异,达到南北平衡和政权巩固,是明代政治体制和统治方针的重要特征;苏松重赋及苏松江浙人不得官户部,正体现了这一特征。 The Ming Dynasty Suzhou, Songjiang, Jiangxi, Zhejiang, “no department headquarters,” the system includes two aspects Su Songjiang and Zhejiang may not be household officials, Su Songjiang and Zhejiang officials may not be officials; but the former is “ancestral System ”, the latter is“ a case ”, the legal status is different. The “ancestral system” was aimed primarily at the officials of Su Song; the “example” was directed at the clerks in Su Songjiang and Zhejang and the “market practitioners” as their reserve forces. The ancestral system was loosened in the later period of Hongwu and became the basis for the Suzu Songjiang and Zhejiang still living in the official department; Yongle early on the overall negation of Jianwen restructuring, as well as the accident occurred by Zhou Chen wearing the Ministry of head, Make “ancestral” two hundred years unchanged. It is an important feature of the Ming Dynasty’s political system and governing principles that the “south people”, especially the economists in economically developed areas in the southern part of the country, are controlled to narrow the political, economic and cultural differences between the north and the south and achieve a balance between the south and the north. And Su Songjiang Zhe not official official department, is a manifestation of this feature.
