With the continuous increase in the number of fishery administration rangers in the Yangtze River basin,it has a bearing on the operation of the 10-year ban on fishing in the basin whether the cor-responding supporting safeguard measures can provide an incentive for fishery administration rangers.Based on the psychological contract theory,combined with the results of the questionnaire survey,an incentive index system for fishery administration rangers was constructed.By comparing and analyzing the difference between the actual perceived value and expected value of each incentive element in the in-centive index system,it was found that the e incentive effect exerted by the interpersonal dimension was obvious,the incentive effect exerted by the development dimension was average,and the incentive effect exerted by the normative dimension was not obvious.In particular,welfare benefits,wage lev-els,equipment configuration,promotion channels,and professional honor had a greater impact on the overall incentive effect.In view of the problems in the incentive mechanism for fishery administration rangers,it is suggested to build a psychological contract incentive model for fishery administration rangers,to establish a fair salary system,to optimize the configuration of patrol equipment,to improve leadership methods,to unblock promotion channels,to shape team culture,to establish an internal mutual aid system,and to innovate honor incentive methods.
