The coordinated development of various new agricultural management entities is regarded as an effective way to achieve agricultural scale management. The coupling development mechanism of integrating family farms into cooperatives and agricultural enterprises has garnered significant attention. This study employs the Tobit regression model and regulatory effect model to explore the influence of land scale management potential on family farms joining cooperatives or agricultural enterprises, and to elucidate the regulatory role of land consolidation in this process. The results indicate that: 1) The current situation of land management area in family farms, past trends of increase, and future intentions of increase all positively influence their willingness to join cooperatives or agricultural enterprises. 2) The impact of land management area on family farms joining cooperatives or agricultural enterprises follows an inverted U-shaped curve. When the land scale of family farms reaches a threshold, the probability of joining cooperatives or agricultural enterprises is at its highest. 3) Land consolidation has a significant regulatory effect on the mechanism by which family farms are promoted to join cooperatives or enterprises. 4) The higher the proportion of the primary industry, the higher the level of mechanization, and the better the momentum of farm development, the more pronounced the positive effect of land scale management potential on family farms joining cooperatives or agricultural enterprises. Therefore, guided by land consolidation and scale management, the integrated development of family farms, cooperatives, and enterprises should be promoted to enhance the agricultural industrial structure and improve production efficiency.
