Abstract： Crop-livestock integration，a traditional Chinese agricultural practice，mitigates pollution from livestock farming and enables resource recycling.However，its economic benefits for smallholder farmers remain ambiguous.To address the practical challenge of“explicit ecological benefits versus unclear economic gains”，Ianalyzed the economic benefits and influence mechanisms of crop-livestock integration from a cost-benefit perspective using 2O21 survey data from eight counties in Yunnan， Guizhou，Shaanxi，and Gansu provinces （Comprehensive Survey on Food Security and Poverty in Rural China）.Key findings include：Adoption rates are higher in southern regions with significant geographic heterogeneity；cultivated land area，multiple cropping index，and household head age positively influence adoption；Economically，integration enhances net agricultural income，net income from crop systems，and gross agricultural revenue，with stronger positive impacts on net income in southern regions；Mechanistic analysis reveals yield increases and income growth，offset partially by rising fertilizer costs-potentially linked to higher technical and financial requirements for manure composting and land application.The research underscores the need to promote standardized manure management technologies among farmers to maximize economic benefits.
