政府间跨域通办合作协议在社会各要素跨区域流动背景下的兴起是现代行政向服务行政转变的必然趋势，然而目前法学界对于政府间合作协议的类型化研究并不充分，不能及时有效回应行政管理实践中涌现的新问题，理论与实践存有的缺口需要通过行之有效的法律制度予以缝合。因此，文章在明确跨域通办合作协议的法律定位后，梳理跨域通办合作协议存在的法律问题，以全过程人民民主与依法行政理念为价值指引，为跨域通办合作协议的法律依据、内容程序、监督保障等方面的法律制度完善提供革新思路。

The emergence of interregional governmental cooperative agreements in the context of cross-regional flow of social factors is an inevitable trend in the transition from traditional administration to service-oriented administration. However, the legal academia has not conducted sufficient research on the typology of intergovernmental cooperation agreements, failing to promptly and effectively address new issues arising in administrative practice. The gap between theory and practice necessitates effective legal frameworks to bridge it. Therefore, after clarifying the legal positioning of interregional cooperative agreements, this paper identifies the existing legal issues and, guided by the values of whole-process people's democracy and law-based government administration, provides innovative approaches to improve the legal systems concerning the legal basis, content, procedures, supervision, and guarantees of such agreements.
