Game analysis on the quality and safety control of pork supply chain - The case study of China

Using the method of static game analysis, the potential risk and responsibility across the entire pork supply chain are discussed from the perspective of all stakeholders involved. Included in the analysis are pig suppliers, slaughterers, pork processors, pork sellers and consumers. The results indicate the following: firstly, the lower the probability of inspections on downstream businesses and the higher the single inspection fee, the greater the probability of harmful substances used by upstream businesses and the higher the costs. Secondly, businesses that actively manufacture and transfer harmful substances in the supply chain cannot add extra costs. Finally, the quality and risk factors in pork production may not follow a strictly linear growth. This study might explain the unique problems that occur in pork supply chain management in large developing countries such as China.
