“…In the platform supply chain, the manufacturer implemented green research and development activities, and the third-party platform adopted data-driven marketing (DDM) activities to promote green products. Liu et al [18] modeled a fresh supply chain consisting of one producer, one blockchain-based traceability service provider, and one retailer as the research object considering government subsidies, which were divided into a fxed strategy and a varying strategy. Li et al [19] examined a two-echelon maritime supply chain consisting of a port and a shipping line under a government green subsidy.…”

The emission control technologies decisions of port and shipping enterprises under subsidy and customers’ low-carbon preferences are discussed from a supply chain perspective. The game models are established under three game models (port-leader Stackelberg game, ship-leader Stackelberg game, and Nash game). The obtained results show that the impact of subsidy and low-carbon preference on demand in its pricing always is considered by the leader in the port supply chain. The profits and emissions in the Nash game are higher than that in the Stackelberg game. When subsidies and customers’ low-carbon preferences are low, the supply chain’s overall profits of using low sulfur oil are higher than that of using shore power. But the supply chain’s carbon emissions of adopting low sulfur oil are also higher than that of adopting shore power. When subsidies and low-carbon preferences of customers are high, the supply chain’s overall profits of using shore power are higher than that of using low sulfur oil. But the supply chain’s carbon emissions of adopting shore power are also higher than that of adopting low sulfur oil. When subsidy and low-carbon preference of customers are in the appropriate(medial) range, the supply chain would choose shore power to reduce emissions from the perspective of profits, and the whole carbon emissions of using shore power are lower than that of using low sulfur oil, so the regulator(government) and enterprises can achieve a win-win situation. Hence for a regulator who has to balance emission control and enterprises’ profits, implementing moderate subsidy within the appropriate range is the better strategy.

“…For example, Liu et al [26] analyzed three subsidy strategies (no subsidy, direct incentive, and indirect incentive) in the agricultural supply chain in the form of subsidy, including subsidy for retail price (i.e., direct incentive)and subsidy for operating costs based on big data and blockchain (i.e., indirect incentive). Liu et al [27] further examined how different subsidy strategies (no subsidy, fixed strategy, and varying strategy) affect the pricing decision in a fresh supply chain. The subsidy objects in this literature are the blockchain technology developer and the producer.…”

“…Then, Liu et al [37] explored three different blockchain adoption strategies (none, one, and both) in two competitive agri-food supply chains considering the blockchain traceability service. Liu et al [27] further considered the blockchain-based traceability information's trust level and consumers' preference for traceability information in a fresh supply chain. Considering the yield uncertainty, Ye et al [28] explored how two competing agri-food supply chains adopt blockchain technology and how the government chooses the optimal subsidy strategy.…”

The quality authenticity of organic agricultural products has always been a hot issue for consumers. Blockchain’s advantages in information traceability and preventing data from being tampered with can reduce fake and counterfeit products, increasing the consumers’ trust in the quality of organic agricultural products. Considering market segmentation of consumer types in organic agricultural products (OPs) and conventional agricultural products (CPs), this study builds a game-theoretical model to explore how participants decide between blockchain traceability platforms and organic subsidy strategies. Results show that the producer should introduce the blockchain when the fraction of blockchain technology’s total cost shared by the producer is smaller and the fixed cost of implementing blockchain is higher or when the fraction of blockchain technology’s total cost shared by the producer is higher and the fixed cost of implementing blockchain is lower. The retailer is inclined to an organic subsidy, and the smaller the market proportion of undifferentiated-conscious consumers (UCCs), the more inclined the retailer is to the organic subsidy strategy. In addition, the market share of UCCs positively promotes the sales quantities and supply chain profits of CPs but is not conducive to the sales quantities of OPs.

“…First, based on China's influence on blockchain policies, some scholars have analyzed and studied policies under different supply chains. Liu et al, based on the national subsidy and incentive policy support for the blockchain [ 22 ], set different supply chains as research objects in the traceability service [ 23 ], agriculture, and [ 24 ] low-carbon fields in the blockchain field, set demand functions according to the characteristics of their respective fields, and analyzed the corresponding subsidy models. Their research provides theoretical guidance for the government to formulate and implement subsidy strategies.…”

Aiming at the problems such as slow traceability efficiency, poor sharing, and the difficulty of matching the throughput of a blockchain single chain structure due to the complexity of the grain food supply chain links, the large number of participants, and the large amount of data information, this paper proposes a grain food blockchain traceability information management model based on the master-slave multichain structure by analyzing the processes and data characteristics of each link in the grain food supply chain; on this basis, the PLEW consensus algorithm based on Raft + improved PoW algorithm is designed for the master chain, and the CI-PBFT consensus algorithm based on trusted information degree is designed for the slave chain. The master chain and slave chain are anchored to each other through hash locking, and the data is uploaded and queried through smart contracts. In order to verify the effectiveness of the model, the blockchain traceability system is designed and implemented based on Hyperledger Fabric2.2. At the same time, it is compared with the transaction throughput and traceability efficiency of the blockchain single chain structure. Through the safety analysis of the data information of a company in Hubei, the results show that the grain traceability system designed and implemented in this study has certain advantages over the blockchain single chain structure in all aspects. It can also solve the grain food security problems that consumers worry about, and provide reference for the research of grain blockchain traceability information management.
