The adjustment of township governance structure is a fundamental issue in the research of township governance. The current governance structure of townships is mainly influenced by the rigidity of township governance brought about by the embedding of technology into the hierarchical system. The "pan centralization" of county governance is highlighted, and townships face structural difficulties such as load operation and overly dense response under multi task governance. This has prompted township governments to adopt a dual non formal institutionalized structural adjustment mechanism, that is, to adjust the dual governance structure through contact structure and organizational restructuring. The township government has improved the efficiency and adaptability of township governance through mechanisms such as absorptive governance and mobilization governance, and completed various higher-level central tasks. The dual adjustment of township governance structure and the adaptation of county governance decentralization have multiple institutional logics. It is not only the adaptation of national governance modernization goals and grassroots governance capabilities, but also the adaptation of grassroots governance championships and grassroots governance structures. It is also the adaptation of informal administrative systems and non-standard rural society.
