摘要:本文利用需求供给模型比较了两种市场经济条件下的农产品质量安全问题,揭示了农产品质量安全事故频出的主要原因是农产品质量的信息不对称、明显的外部性特征和典型的公共物品属性, 而这些因素在现实的市场经济情况下是经常的、普遍的, 因此, 只有靠政府加大监管力度, 才能消除农产品质量安全问题。
简介
I. Introduction
农产品绝大部分直接作为食品或经过初、深加工后成为食品供人们消费。“民以食为天,食以安为先”。随着我国经济社会的快速发展,人们生活水平的改善,食品安全问题越来越引起广泛关注。近年来,农产品质量安全问题不断出现,给广大消费者的身心健康造成极大的威胁,同时也给行业造成重大的损失,如瘦肉精、猪链球菌、注水猪肉、毒大米等事件。
Most agricultural products directly as food or after the beginning of deep-processed into food for human consumption. "Food to safety first." With China's rapid economic and social development, people's living standards improve, more and more food safety issues caused widespread concern. In recent years, agricultural product quality and safety issues continue to emerge, to consumers caused great physical and mental health threat, but also caused considerable damage to the industry, such as clenbuterol, Streptococcus suis, Zhushuizhurou, poisonous rice and other events. Not only affects the quality and safety of agricultural products to the people's health and lives, but also affect a country's agricultural market order and export trade of agricultural products, and even affect people on the economic and social security of expectations, thereby reducing social welfare.
At present, the developed countries mainly through legislation, build quality and safety inspection system, deepen the reform of management system and traceability system improvement ○ 1, and several other aspects to strict quality and safety gates. Liddell (2001) compared the major exporting and importing countries of pork livestock traceability system, the distinction between the livestock traceability system traceability, transparency and quality assurance concepts, and that different countries there are differences of their livestock accommodation system that can be traced back systematic economic incentives could help to define traceability system level economic benefits. Quality and safety of agricultural products in China has just started research management issues, related research small. Among them, Yuan Xueguo with the theoretical analysis of the adverse selection under asymmetric information, safety of agricultural products market in general will be pollution-free vegetable vegetables out of the market, resulting in a lemon market in the process. Zhou wing depth analysis of all aspects of food safety management and aspects of information asymmetry, theoretically demonstrated the government's food quality and safety management system is essentially a cost-benefit information management issues. Xiuqing proposed government food market from the traditional control methods should also direct the production process and product standards for quality control to gradually shift the control of information, through the disclosure of information, the provision of public information and education, etc. to establish an effective quality signal transmission mechanism, ensure food quality and safety goals.
In this paper, the use of demand supply model compares the two market economy under the conditions of quality and safety of agricultural products, agricultural products quality and safety incidents reveal frequent quality of agricultural products is mainly due to information asymmetry, obvious external characteristics and typical public goods , and these factors in the real market economy is often the case, universal, so that only rely on the government to intensify supervision, the quality and safety of agricultural products in order to eliminate the problem.
