Does adoption of the rice-crayfish co-culture model improve farmers' income?

ABSTRACT: This study empirically assesses the income effects of the rice-crayfish co-culture model using endogenous switching regression (ESR) and mediation models, based on survey data from 1,058 farm households in Hubei Province. Key findings reveal that adoption of the rice-crayfish co-culture model significantly boosts farmers' total income: counterfactual analysis shows non-adopters would experience a 22.423% decline in average household income if they ceased adoption. The adoption of the rice-crayfish co-culture model differential impacts on the income of various farmer groups. This divergence primarily stems from the model's significantly stronger positive effect on agricultural income compared to its minimal dampening effect on non-farm income. By examining the mechanism of its effect on far
