Study on Benefit Distribution of New Crown Vaccine Co-Distribution

Under the background of the new crown epidemic, the cold chain distribution of vaccines becomes the key to the success or failure of immunization. Based on the cooperative alliance of cold chain drug distribution enterprises, the cooperative game model of cold chain drug distribution enterprises is established based on the Shapley value for the benefit distribution of the participating subjects. On this basis, the improved Shapley value allocation model is constructed by considering the overall strength and risk-bearing ability of the participating players and quantifying the actual contribution value of each participating player. The results show that the improved allocation model can effectively avoid the phenomenon of equal sharing and make the benefit distribution results fairer.
