This paper focuses on a Pareto cooperative differential game with a linear mean-field backward stochastic system and a quadratic form cost functional.Based on a weighted sum optimality method,the Pareto game is equivalently converted to an optimal control problem.In the first place,the feedback form of Pareto optimal strategy is derived by virtue of decoupling technology,which is represented by four Riccati equations,a mean-field forward stochastic differential equation(MF-FSDE),and a mean-field backward stochastic differential equation(MF-BSDE).In addition,the corresponding Pareto optimal solution is further obtained.Finally,the author solves a problem in mathematical finance to illustrate the application of the theoretical results.
