Abstract: Accurately measuring the degree of rural hollowing, revealing the spatial distribution pattern and the influencing factors of rural hollowing in counties in the northeast black soil region are of great significance for regulating hollowing villages according to local conditions and promoting rural revitalization. This paper takes the typical county in the northeast black soil region as an example to measure the degree of multidimensional rural hollowing and its coupling coordination. Results show that: 1) the multidimensional hollowing of rural areas is the result of the interaction of multiple elements of rural regional systems such as population, land, and economy; 2) the degree of rural hollowing in Baiquan county is generally high, the difference between village and township is obvious, and the level of economic hollowing is higher than other dimensions. The proportion of outflow population, per capita net income and the proportion of farmland transfer are the dominant factors affecting rural hollowing; and 3) the interaction intensity of rural population, land and economic hollowing is generally high, showing a low-level coordinated evolution. There are obvious differences in the coordination state between the two. Among them, the "population-land" hollowing coordination is the worst. The single industrial structure, the high proportion of planting industry, and the low income of farmers are important reasons for the hollowness and imbalance of human-land-industry in Baiquan County. Therefore, to systematically construct the coupling pattern of various elements in rural areas, this paper provides some policy suggestions, including zoning consolidation and improving rural regulation system.
