Special Aquatic Products Supply Chain Coordination Considering Bilateral Green Input in the Context of High-Quality Development

Abstract

The high-quality development of fishery puts forward two requirements for the supply of Aquatic Products(AP): The first is to increase the supply of high-quality, high-end and safe AP based on market demand;The second is to promote green aquaculture. Under this background, Special aquatic products (SAP) have become the main force of green aquaculture due to their higher nutritional value and good quality, the green development of Special aquatic products supply chain (SAPSC) can solve the urgent needs of consumers for “quality and healthy” AP. Combining with the characteristics that SAP farming is dominated by producers, we construct the Stackelberg Model of producer-dominated SAP, and analyze the different operation results of SAP in traditional aquaculture model(TAM) and green aquaculture model(GAM). Furthermore, the paper studies the optimal decision-making of supply chain based on the bilateral green input of producers and retailers, and designs a revenue-sharing contract(RSC) to coordinate the SAPSC. The main results are as follows: Compared with TAM, the demand for products under GAM is greater. And the producers and retailers are more profitable. The basic greenness and marketing level of the products have a driving effect on green development of SAPSC. The RSC is conducive to encouraging supply chain members to make green inputs. Finally, by analyzing the contract parameters and supply chain parameters, the validity of the contract and the correctness of the conclusion are verified.
