Abstract: In order to analyze the benefits and influencing factors of different modes of manure resource utilization in pig farms in Xiangzhou District, Xiangyang City, in this study, entropy value method was used to measure the weight of evaluation index of manure resource utilization model of large-scale pig farming from 13 indicators of economic, social, ecological and technical dimensions. The TOPSIS method was used to establish a comprehensive evaluation model of manure resource utilization mode of pig breeding, and the comprehensive benefits of each model were analyzed. The Tobit regression model was used to explore the influencing factors of the comprehensive benefits of different pig manure resource utilization modes from three aspects: the basic characteristics of the farmer, the operation status of the farm and the external social environment. The results showed that the weights of economic, social, ecological and technical benefits in the criterion layer were 0.337 7, 0.360 8, 0.223 8, 0.077 7, respectively, among which the social benefits had the largest weights, followed by economic, ecological and technical benefits. In the index layer, the three indexes of employment, manure resource income and planting and breeding balance rate had a large weight, which were 0.329 1, 0.299 7 and 0.170 0, respectively. The comprehensive benefit of the biogas fermentation mode was the highest in small and medium-sized farms, and the comprehensive utilization mode was the highest in large-scale farms. Breeding income, breeding scale and supporting cultivated land area had a significant impact on the comprehensive benefits of manure resource utilization mode. Among them, breeding income and supporting cultivated land area were positively correlated with the comprehensive benefit of the manure resource utilization mode, while the breeding scale was negatively correlated with the comprehensive benefit of the manure resource utilization mode.Accordingly, the author proposed to accelerate the research and development of manure treatment and utilization related technologies and improve the manure resource utilization model, strengthen the circular development model of planting and breeding, and vigorously promote the combination of planting and breeding, cultivate third-party service providers to solve the problem of small and medium-scale manure utilization, increase government support and improve government incentives and other measures.
