Abstract
Purpose There are particularly high fresh agricultural product (FAP) loss rates in actual supply chain
operation and the development of FAPs e-commerce is hindered to some extent. The purpose of this paper is
to achieve the coordination of three-layer FAP supply chain and maximize profit through the contracts among
the supply chain members.
Design/methodology/approach A three-layer FAP supply chain that consists of a fresh produce
e-commerce enterprise, third-party logistics service provider (TPLSP) and community convenience store
under e-commerce environment is considered. New game models are developed and optimal decisions in
centralized and decentralized channel are characterized. Different contract coordination mechanisms are
designed to improve the supply chain performance. Finally, computational studies are conducted.
Findings The decentralized supply chain cannot be coordinated by a freshness-keeping cost-sharing
contract, and it can be coordinated by a freshness-keeping cost-sharing and revenue-sharing contract. The
optimal unit online selling price, unit logistics distribution price, fresh-keeping effort and unit self-collection
service price can all be achieved.
Practical implications The paper provides a practical gui deline to managers in fresh produce industry
in terms of how to cooperat e with other supply chain members so as to maxi mize total profit and achieve
Pareto improvement wh ile also supply the fres hest and safest produce t o the target market unde r
e-commerce environment.
Originality/value Few studies have explored the coordination of three-layer FAP supply chain under
e-commerceenvironment with TPLSP and communityconvenience stores participationin decisions, especially
considering that the market demand for FAPs is affected by freshness and unit online selling price. In this
paper, all these scenarios are taken into account and corresponding mathematical models are developed.
In particular, different contract coordination mechanisms aredesigned and examined simultaneously.

1. Introduction
With the rapid development of social economy and the change of consumersconsumption
pattern, consumers demand for fresh agricultural products (FAPs) has been undergone a
transformation from quantity to quality. Safer and fresher FAPs have been paid more and
more attention to recently. There are some characteristics about FAPs, such as perishability,
freshness decreases with time, large market demand, so appropriate operation and
management in supply chain play an important role in ensuring their quality (Dan et al.,
2011; Zhang et al., 2017). In a traditional way, the FAPs were mainly transferred from the
large wholesale market, through small- and medium-sized food markets or supermarkets to
consumers. That means it has to undergo a long-distance transportation and many
intermediate links to reach the target market. The rapid development of FAPs e-commerce
makes it possible to transport FAPs directly from the original producing area to consumers.
However, in actual supply chain operations, there are many issues such as high loss rate of
FAPs, low preservation level of FAPs, high cost of cold chain distribution, which restrict the
development of FAPs e-commerce seriously and cause it to suffer substantial losses.
According to Cai et al. (2010) and Zheng et al. (2017), the loss rate of perishable products in
developed countries is up to 15 percent due to damage and spoilage, and it is much higher in
developing countries, reaching approximately 25 percent or 30 percent. There is as high as
$8.9bn loss of the supply chain of fruit and vegetables, representing about 30 percent of the
annual production in China (Yan et al., 2015).
The emergence of logistics distribution mode ( fresh produce e-commerce enterprise +
TPLSP +community convenience store) may help solve those problems to a certain extent.
In this mode, fresh produce e-commerce enterprise can deliver the FAPs of online shopping
to consumers by employing the specialized logistics service facilities and equipment of
third-party logistics service provider (TPLSP), and take community convenience store as a
temporary storage point, which reduces the high costs of a self-built cold chain logistics
system. The freshness-keeping effort of TPLSP (such as transportation time, shipping
temperature and protection material, etc.) may affect the FAPsfreshness, which may affect
consumersonline shopping satisfaction and second purchase intention and further
indirectly affect the profits of fresh produce e-commerce enterprise and community
convenience store. Therefore, it needs the three supply chain parties to work more closely
together to keep the freshness of FAPs. However, as an independent subject in the supply
chain, the fresh produce e-commerce enterprise, TPLSP and community convenience store
try to maximize their individual expected profits when they make decisions. As a result,
there is a double marginalization and the profit of the whole FAPssupply chain will lose a
lot. Therefore, to pay attention to the preservation of FAPs and the cooperation of supply
chain members, and to explore the operational strategies of FAPssupply chain
coordination to improve the operating performance of supply chain and the quality of
peoples life have important significance.
The purpose of the paper is to explore the coordination of three-layer FAPssupply chain
under the e-commerce environment with TPLSP and community convenience stores
participation in decisions. We will investigate optimal decisions of the three participants
