Evaluating the Effects of Grassland Ecological Compensation on Herders'Income and Policy Credibility
Leveraging survey data from 304 herdsmen in Henan Mongolian Autonomous County,Qing-hai Province,we employed ordinary least squares(OLS)and quantile regressions to investigate the impact of the grassland ecological compensation policy on the herdsmen's income.Additionally,an ordered Probit model was used to analyze the factors influencing herdsmen's perception of the policy's credibility.The results showed a positive association between the policy and herdsmen's income level.Notably,the impact was significant for low-and middle-income groups,but not for high-income herdsmen.Furthermore,the compensation standard and perceived impact on grassland protection function emerged as crucial determinants of policy credibility,while supervision and information disclosure did not exhibit significant positive effects.Therefore,differentiated policy design tailored to income strata is recommended.Additionally,strengthening implementation supervision and enhancing information transparency are crucial for ensuring the policy's long-term effectiveness and promoting widespread adoption.
