Abstract: Abstract Considering the adverse impacts of pollutant emissions from port areas on the environment, an analytical model is developed to investigate optimal decisions for two port-based supply chains with or without governmental pollution tax. When the governmental pollution tax is introduced, the impacts of local governments independently determining pollution tax and jointly determining pollution tax on the environment and transport chains are investigated, respectively. The results show that the enterprises will not pay attention to the pollution if the governmental pollution tax is not introduced, which will result in the higher pollution level than the optimal level. It is interesting to note that negative pollution tax (i.e., subsidies) is more likely to occur when local governments set pollution tax separately. When local governments cooperate with each other to determine pollution tax, the pollution spillover problem can be solved, and optimal social welfare can be achieved. Thus, cooperation between local governments is more effective. Furthermore, a numerical example is given to analyze the influences of the local pollution damage coefficient and the spillover pollution damage coefficient on the optimal strategies of all participants.
