The game analysis of enterprises in FSDN on construction the traceability system

Many factors influence the implementation of traceability system in our country, an important factor is the core enterprises lack desire. This paper constructed the Nash game equilibrium in traditional food supply chain and the Pareto game equilibrium in food supply and demand network (FSDN), and analyzed the relationship between investment and income in the two situations. In the traditional non-cooperative state, enterprises will invest a low level in food traceability system for their own interests. In the Pareto equilibrium model, enterprises in FSDN will invest a higher level in food traceability system construction.
