农产品流通需求主体的质量检验严格程度、检验水平和惩罚力度是供给主体选择质量投机行为的主要因素.供给主体通过获得这些信息进行质量安全投入决策。供给主体较高的质量投入,会使得需求主体降低质量监测成本,转而提高流通技术和流通能力,同时,整个流通体系的交易成本降低、流通水平得以提升;反之,供给主体较低的质量投入,会使得需求主体提高质量监测成本,转而降低流通技术和流通能力,进而形成整体水平偏低的流通体系。增加农产品质量安全投入、保证流通上下游主体的信息交互,是提升农产品流通体系整体水平的关键。
The level of strictness, the standard of inspection and the intensification of punishment of quality inspection by the main demanders of agricultural products circulations is the key factor considered by the main suppliers while choosing the opportunistic behavior in terms of quality. By obtaining these kinds of information, the main suppliers make decisions on quality safety investment. The suppliers' higher investment in quality will reduce the demanders' cost of quality inspection and improve circulation technology and the capability for circulation. At the same time, the transactional cost of the circulation system as a whole will be reduced and the level of circulation will be improved. Otherwise, the suppliers' lower investment in quality will increase the demanders' cost of quality inspection, hinder the improvement of circulation technology and lose the capability for circulation: the overall level of the circulation system will be lowered. Increasing investment in agricultural products quality and safety and guaranteeing the information interaction among all the upstream and downstream players is the key for us to improve the level of agricultural products circulation as a whole.
