民国二年（1913）北洋政府颁行《划一令》，在全国推行废府存县，清代延续二百余年的奉天府随之裁撤。研究表明，奉天府长期实行无直辖地方的府制，事权交错导致行政效率低下，而清末新政区的不断析出进一步压缩了其管辖范围；晚清新政与战乱导致地方财政入不敷出，府级机构因缺乏独立财源而迅速空心化；清末旗民二元体制瓦解、辛亥革命的冲击及中央统一政令的推行，从制度层面消解了府制的存续基础；日俄势力在东北的扩张，使铁路附属地、商埠地形成独立治权，进一步架空了奉天府的行政职能。多重因素共同作用下，奉天府最终裁撤改县，这一变革也推动东北地方行政体系完成与内地规制的统一，逐步迈入近代治理阶段。

In the second year of the Republic of China (1913), the Beiyang government promulgated the Uniform Organization Decrees, initiating the nationwide policy of abolishing prefectures while retaining counties. As a result, Fengtian Prefecture, which had existed for over two hundred years in the Qing dynasty, was abolished. Research shows that Fengtian Prefecture had long operated under a system with no directly governed territory, leading to overlapping administrative powers and low efficiency. The continuous establishment of new prefectures, subprefectures, and counties during the late Qing further reduced its jurisdictional scope. The New Policies and successive wars in the late Qing caused severe local fiscal deficits, and the prefecture-level institutions, lacking independent financial resources, rapidly hollowed out. The collapse of the bannermen-civilians dual system, the impact of the 1911 Revolution, and the implementation of unified central decrees all eroded the institutional basis for the survival of the prefecture system. Moreover, the expansion of Japanese and Russian influence in Northeast China gave rise to railway attached areas and treaty-port zones with independent administrative powers, further stripping Fengtian Prefecture of its actual functions. Under the combined effect of multiple factors, Fengtian Prefecture was eventually abolished and converted into a county. This reform also helped align the local administrative system of Northeast China with that of the interior, gradually ushering in a modern phase of governance.
