With the change of economy,society,behavior expectation and population characteristics,subjective survival belief has become an important factor affecting residents'consumption decision.Based on the data of the 2018 China Health and Pension Tracking Survey Database and the 2018 China Population and Employment Statistical Yearbook,this paper uses Kohl's method,Val's method and index method to characterize and measure the subjective survival belief pessimism of middle-aged Chinese residents.Based on fuzziness,this paper introduces the pessimistic subjective life belief into the consumption decision model and obtains the analytic solution of the robust optimal strategy.We found that pessimism of subjective survival belief inhibited residents'consumption,while objective mortality,risk-free interest rate and marginal wealth utility weight all affected residents'consumption strategy.This paper puts forward a new perspective for the cause of insufficient consumption rate of Chinese residents.
