The relevant subjects are the direct relationship with the quality safety of agricultural products, and play a key role in ensuring the quality safety of agricultural products. This paper analyzes the behavior performance of production subject, circulation subject, consumption subject, supervision subject on agricultural products' quality safety, and puts forward the following countermeasures to improve the quality safety of agricultural products according to their behavior performance: to regulate the production of agricultural products, to strengthen the management and control agricultural inputs, to improve the safety supervision system of agricultural products, to accelerate the development of new circulation subject, to actively cultivate and develop new types agricultural business, to accelerate the process of agricultural scale management, to establish the multiple supervision subject, and to make up the regulatory loopholes.展开更多
