RESUMEN
[Introduction] To design a workable compensatory scheme of new cooperative medical system (NCMS) in rural China, 'Monte Carlo Simulation Techniques' is developed based on the data of a multistage random sampling survey. The total compensation rate, the decreased percentages of poverty caused by diseases and the deficit ratio of fund a 0.3782, 0.6540 and -0.0794 respectively, when the main strategy of inpatient reimbursement is recognized as 'serious illness'. The deficit ratios of funding appeared to be 0.4840, 0.4091 and -0.3789 when the main strategy of outpatient reimbursement is recognized on minor diseases. Compensation for minor diseases is more important than that of serious diseases. Considering the further impact of minor diseases on peasants, we should incorporate compensation for minor diseases into the compensatory scheme of NCMS.
