元朝時將宋、遼、金時期的監當官、雜班官所負責的事務，在戶計制度的基礎之上，產生了一種獨特的管理制度，將所有百姓編為不同的戶計，設置各自不同的職官管理，負責政府各種需要，管理這些事務的官員便是雜職官。明初承元制，設置雜職官，用來管理了除了田賦以外的各種政府收入來源，以及提供交通、訊息、醫療、天文曆算等等服務，對政府運作有相當重要的意義。明初雜職官有以下幾個特色：一、有獨立於州縣的衙署；二、有隸屬自身衙門的胥吏與戶役，獨立執行職務；三、獨立的會計單位；四、考覈由中央機構進行，這些特色是延續元代制度而來。雜職官並非州縣政府的下屬官員，雜職衙門也不是州縣的下屬機關，其所管理的事物更非來自州縣的分配或要求。從明初雜職衙門的設置，讓我們對明初地方制度能有更具體的理解，對明清中國是否存在縣級以下行政區能也能有更正確的認識。同時，雜職官制度也是元明之間制度延續的一個顯著例子。

The Zazhiguan（雜職官） system of Ming Dynasty was used to manage the government’s various income sources except form agricultural land tax, and provide traffic, information, medical, celestial almanac, and other services, which was very important for the operation of the government. In Yuan Dynasty, the affairs of the jiandangguan（監當官） and the Zabanguan（雜班官） were designed to be based on the Huji（戶計）system, which formed a unique management system. This management system classified the people into different Huji for different officials to manage so as to satisfy various requirements of the government; the officials for managing these affairs are Zazhiguan. The features of the Zazhiguan of Ming Dynasty are as follows: (1) they had the government agency independent from the Zhou and the Xian（州縣）; (2) they had clerks（Hsu-li胥吏） and Huyi（戶役） subordinate to the government office; (3) they had independent accounting department; (4) their performance were assessed by the central government. The Zazhiguan system of Ming Dynasty inherited from Yuan Dynasty, so most of the above features remained in the system of Ming Dynasty. The miscellaneous officials were not the subordinates of the county government; the Zazhiguanyamen（雜職衙門） also was not subordinate to the county; further, the affairs managed by the Zazhiguan were not designated by or required by the county. The Zazhiguanyamen of Ming Dynasty can help us more concretely understand the local government system of early Ming Dynasty, and precisely understand whether China had an administrative district lower than Xian during Ming Dynasty and Qing Dynasty. In addition, the Zazhiguan system was another obvious example of the systems inheriting the systems of Yuan Dynasty and Ming Dynasty.
