Agricultural products are easy to deteriorate in long-distance transportation. Excessive circulation loss not only increases the cost of fresh agri-product supply chain, but also damages the safety and quantity of fresh agri-products. The value loss of fresh agriproducts under different transportation modes was studied. This paper analyzes the conditions for the supplier to choose normal temperature transportation and cold chain transportation, and the influence of different transportation modes on the retailer's decision. The value loss of fresh agri-products under different transportation modes was studied. The conditions of choosing normal temperature transportation or cold chain transportation and the influence of different transportation modes on the retailer's decision are analyzed. It is found that when the supplier chooses cold chain transportation, the retailer and the whole supply chain can get more profits. The retailer is encouraged to make appropriate supply chain contracts with the supplier, such as the improved revenue-sharing contract or the cost-sharing contract, and the supplier is encouraged to adopt cold chain transportation mode to improve the utilization rate of cold chain transportation of fresh agri-products. Consumers' sensitivity to freshness has a great impact on the strategies of supply chain members. The contribution of this work also includes reducing the circulation loss of agri-products and providing guidance for the operation and management of agri-products enterprises.

By constructing a dual-channel fresh agricultural product (FAP) supply chain consisting of a retailer and a supplier, this paper considers the effect of fresh-keeping level on the freshness of perishable products and constructs a time-varying demand function based on freshness. The operating cost of the internet channel to the supplier has also been considered in the model. Optimal pricing strategy and profits of supply chain members under dual channels are investigated respectively in this paper. Comparing the optimal profit under traditional single-channel and dual-channel supply chain, we obtain the condition that the internet operating cost should satisfy. Given the situation where the supplier obtains profit while the retailer loses after the supplier introduced the internet channel, this paper proposes a revenue-sharing contract to make up for the loss of the retailer and achieves a win-win situation. Research shows that in the numerical analysis the supplier’s and the retailer’s profit can only be improved when the operating cost of the internet channel  c  0  and revenue-sharing ratio ψ are within a certain range. When ψ ≥ 0.4 and 0 ≤ c 0  ≤ [[EQUATION]] , Pareto improvement will be attained on both sides in the supply chain.

The fresh product supply chain suffers from the quantity loss and quality loss due to its perishability in long-distance transportation, which affect the health of customers and the sustainable development of supply chain. Using low-cost normal temperature transportation or high-cost cold chain transportation has become a problem for transportation enterprises. This paper aims to investigate the impact of different transportation modes on the supply chain performance. The operation strategies of the supply chain are analyzed under three situations: no coordination contract, wholesale price contract, and revenue-sharing contract. Taking Zhanhua winter jujube as an example, the correctness of theoretical analysis is verified. The main findings are as follows. Supply chain participants, including consumers, can benefit from cold chain transportation. That the cost of cold chain transportation is below the threshold is the basic condition to use cold chain transportation. The retailer has the incentive to encourage the supplier to use cold chain transportation by increasing the wholesale price, but the wholesale price should be set within a certain range. The supplier has the incentive to use cold chain transportation under the revenue-sharing contract, but the revenue-sharing proportion needs to be within a certain range to ensure the retailer's profit. The revenue-sharing contract is superior to the wholesale price contract, and wholesale price contract is superior to no coordination contract.
