Study Of Information System About Agricultural Products Quality Control

In recent years, the problem about agricultural products quality safety has already became the focus of society .The asymmetrical information existing in producers, sellers and makers is the basic reason why the problem about agricultural products quality safety exist .How to eliminate or weaken asymmetrical information existing in correlative people becomes the question which urgently to be solved. This text research this question, the main ideas are as follows:(1)There exists asymmetrical information about agricultural products quality (experience goods and credence goods character)between producers, sellers and makers, which result in adverse selection in agricultural products market and opportunism behavior of producers and sellers of agricultural products,'lemon market'is shaped, and market mechanism doesn't work. For this reason, asymmetrical information is the reason why marketing mechanism doesn't work, and the basic measure to improve agricultural products quality is to eliminate or weaken asymmetrical information. Set up information system about agricultural products quality safety is a useful way to solve this problem.(2)Based on analyzing the external environment, this text points out that it is time of researching and constructing the information system about agricultural products quality safety. Target users of the information system have producers, sellers, makers, the purpose of designing the information system is to meet the information needs of the target users, and eliminate or weaken asymmetrical information existing in correlative people. For this reason, information system about agricultural products quality safety can have the following four parts: information publishing system, traceability system, risk information gathering and communicating system and information service system. The overall goal of the information system is to construct a comprehensive unified information collection, publication and exchange platform about agricultural products quality safety, unify information scattered in various departments to improve information services. The information system also should be a coordinate and efficient network structure.(3)Based on the state's information publishing policy about agricultural products quality safety, this text points out that the information publishing system is constructed by information departments of agricultural products quality safety testing agencies, and levels of agricultural products quality safety information center, the information system based on establishment and perfection of the levels of agricultural products quality safety testing agencies, and agricultural products quality safety routine testing system. And it points out that the information publishing system has six subsystems: The agricultural product quality specification subsystem,the agricultural investment subsystem,the agricultural product quality safely trace subsystem,the agricultural investment and the agricultural product quality safe monitor result subsystem,the agricultural investment and the agricultural produces product the operator prestige subsystem .(4)The agricultural products processing quality information system took the nature burette quantity system the important constituent, it moves the success or failure directly relates the final product the quality, it played the vital role in the agricultural product quality control. This system mainly constitutes by the below module: The system administration module and the maintenance module, the quality basic administration module, the quality documents administration module, the supplier quality control module, expects the performance test administration module, the manufacture process quality control module.(5)The agricultural product circulation quality control information system is guarantees the agricultural product quality security the effective tool. The traceability system about agricultural products quality safety is a security system based on risk management. It correctly identifies, records, communicates and manages the key information involving agricultural products quality safety along agricultural supply chains to realize tracking, tracing and warning, and eliminate hazards and reduce losses. Considering the goal of constructing traceability system of agricultural products, it should have the following four subsystems: The edible agricultural product security collection of information and the analysis system, track and traces the system, the risk in advance for the system, the information issue system and the information consultant service system..Finally this article in obtained to above three systems research foundation in has supplied the chain based on the entire agricultural product the agricultural product quality control information system.
