Security Researchers At Wholesale Markets Of Agricultural Products Quality Mode

Agricultural products safety has respect to millions of households and is the focus of the government and the concern of the whole society. In China, more than70%of agricultural products through the wholesale market inflows consumer’s "basket" and the wholesale market has become the main channel for the circulation of agricultural product. However, agricultural products safety incidents occurring frequently not only cover a wide range and have great harm, but also expose inherent flaws of agricultural products safety management in wholesale market. How to protect agricultural products safety under the wholesale trade mode has become a serious problem. In view of this, the paper using "agricultural products safety under the wholesale trade mode" as the subject of the research work aims to analyze the factors affecting the safety of agricultural products and explores the farmers, wholesalers, wholesale market and the government’s strategy choice behavior under the wholesale trade mode based on these factors to achieve the goal of ensuring agricultural products safety by low cost and high efficiency.This paper chooses agricultural products safety under the wholesale trade mode as research subject and summarizes the macro factors and micro factors affecting safety of agricultural products and point outs that income is the most important factor. The coordination problems of supply chain composed of a farmer and a wholesaler are studied and the terms of reaching revenue and penalty sharing contract between the farmer and the wholesaler are analyzed. Furthermore, the reasons of safety incidents of agricultural products in wholesale occurring frequently are discussed based on game theory and optimal regulatory strategy are researched based on CAS theory. And considering patent information is the basis of achieving agricultural "safety premium", the wholesaler-dominated agricultural products safety traceability system is designed and construction path is proposed. It can be seen that the entire researches of agricultural products safety under the wholesale trade mode are completed through seven chapters.First, the research background and significance are analyzed and the concepts of agricultural products and agricultural products safety are introduced. In this paper, agricultural products safety means that the safety of agricultural products is in line with national mandatory standards and requirements and will not cause harm and potential harm to consumers. Thus the main content of this paper and brief technical route are led and the innovation points are pointed out.Through literature review, the macro factors and micro factors affecting agricultural products safety are summarized. The macro factors include laws and regulations system, standards system, inspection and testing system, the regulatory system. The micro factors include supply chain organization model, information transmission, distribution of income, cognition and consciousness, knowledge and technology, reputation. Agricultural products safety factors model is established and the relationship of the macro factors and micro factors is commented. Analysis indicates that profit is the most incentive factor to the safety behavior choose of each party on the supply chain and the delivery of the safety information is the basis to achieve "security premium"After briefly introducing the coordination theory of supply chain, safety control and coordination research of supply chain composed of a farmer and a wholesaler is done based on the distribution of income. Using relevant supply chain coordination theories, the behavior decision of the supply chain members is analyzed in three different scenarios which include non-cooperation, cooperation and using revenue and penalty sharing contract based on a two-stage supply chain between one farmer and one wholesaler. The farmer and wholesaler reach a safe or unsafe sharing contract depends on the specific conditions. Compared with the cooperation situation, the situation using revenue and sharing penalty contract to improve profit of the supply chain isn’t satisfied. However, compared with the non-cooperation situation, the situation using the sharing contract make the profit of the farmer and wholesaler to improve.Not only revenue and penalty sharing contract between one farmer and one wholesaler in the production area would affect agricultural products safety, but also the behavior selection of wholesale in the circulation area would affect the safety. Based on game theory, the reasons for agricultural products safety events occurring frequently in the wholesale markets are obtained. It’s pointed out that the invalidity of the existing market mechanisms and defects in the laws and regulations make the wholesale market choose not to regulate the management, while this behavior will induce suppliers including farmers and wholesalers to provide unsafe agricultural products in order to get more revenue. To change this situation, the appropriate recommendations are given to maximize the security management role of the wholesale market.The above analyses of supply chain coordination and game theory are static. However, the government, wholesale markets and numerous suppliers are all "live" bodies having their own goals, preferences and initiative. The Government aims to produce a sampling pass rate is higher than a certain level, while wholesale and suppliers as business entities, the goal of them is to seek maximum benefits. The agricultural products safety system constituted by them is a complex adaptive system exhibiting strong characteristics of uncertainty and dynamic evolution. Based on the analysis of complex adaptive systems, the models of the government agent, wholesale market agent and supplier agent are built and the properties and regulation of each model are set. The situations of agricultural products safety are discussed under different government supervision strategies and the optimal government regulatory strategy is put forward to ensure the safety of agricultural products with low cost and high efficiency.The increase revenue of safe agricultural products supply chain is from agricultural products "security premium" and the realization of "security premium" depends on effective transfer of information. The arising of agricultural products safety problems precisely due to asymmetric information and adverse selection on its supply chain. Establishing the wholesaler-dominated agricultural products safety traceability system can transfer the information effectively and make information symmetry realize. In this paper, the theoretical analysis and design of the wholesaler-dominated agricultural products safety traceability system have been done and its construction path has been put forward. The traceability system has two parts that are the market information system and the agricultural products safety information traceability platform to fully mobilize the initiative of each agent in market and make the system run efficiently and feasibly.The paper uses supply chain coordination theory, game theory and complex adaptive systems theory to discuss the behavior policy choices of the farmers, the wholesalers, the wholesale market and the government under the wholesale trade mode and builds the wholesaler-dominated agricultural products safety traceability system in order to provide reference for agricultural products safety management under the wholesale trade mode.
