Abstract: Digital rural area is a key aspect of rural revitalization and an integral part of building a digital China. Tianjin, as a representative region for upgrading modern urban agriculture, is actively implementing comprehensive measures to promote rural revitalization and requires policy support. However, the construction of an evaluation index system for digital rural areas in China lags behind the demands of comprehensive promotion of rural revitalization. It hinders the identification and resolution of shortcomings in the development of digital rural areas that contribute to overall rural revitalization, thereby affecting effective policy formulation. This article aims to construct an evaluation index system for assessing the level of development in digital rural areas in China. The proposed system includes six primary indicators and seventeen secondary indicators with comprehensive promotion of rural revitalization as its objective. By utilizing grey relational analysis（GRA）method and using per capita disposable income in rural areas as a reference sequence, historical data from twelve typical provinces and cities in China regarding information construction in digital villages were quantitatively analyzed to establish an evaluation system that supports comprehensive promotion of digital village construction for overall rural revitalization. Based on this framework, we evaluated the level of digital village construction in Tianjin. Our findings indicate that while digitized infrastructure is relatively complete in towns adjacent to urban areas, there remains unfinished transformation towards modern agricultural production models driven by digitization. Additionally, deficiencies exist within pilot demonstration projects aimed at promoting digital villages. Consequently, we propose policy suggestions from various perspectives such as constructing assessment systems, negative lists, and promoting informatization with the aim to provide decision-making support for Tianjin's comprehensive promotion.
