The agricultural production regulated by cooperative specifications guarantees the supply quality, which in turn is an important factor that affects the cooperation in the “FarmingSupermarket Docking”. The result of the cooperatives production specifications and supply quality on the stability of the “FarmingSupermarket Docking” supply chain shows: both the production norms and supply quality have significant positive impact on the stability of the “Docking” supply chain; the production specifications play a partial intermediary role in the stability of the supply chain; in the low participation group, the production specifications play a relatively greater role; in the high participation group, the impact of supply quality is even greater. So, it is proposed that the cooperative should establish effective production specifications to improve production efficiency and quality, and for cooperatives with different levels of participation, the focus of channel construction should be different and classification guidance should be carried out.
