Legal analysis: the source and composition of social assets are complicated, which can be roughly divided into membership shares, commercial accumulation and national policy support. In the early days of the founding of New China, as a cooperative economic organization spontaneously established by farmers, the main source of funds for supply and marketing cooperatives was members' shares. In the subsequent development, supply and marketing cooperatives have accumulated a lot of property through long-term operation. During the planned economy period, supply and marketing cooperatives, as the main channel of rural commodity circulation and the leading force of rural market, enjoyed the special policies of the state in operating agricultural materials, cotton and other important agricultural and sideline products, fireworks and firecrackers, bamboo and wood. Under the market economy system, the supply and marketing cooperatives have deepened their reform, developed their operations and continuously strengthened their economic strength. For decades, higher-level cooperatives have invested more in the development of lower-level cooperatives, and governments at all levels have also given different forms of support.
