Cohesion of Agricultural Crowdfunding Risk Prevention under Sustainable Development Based on Gray–Rough Set and FAHP-TOPSIS

Agricultural crowdfunding has promoted the development of China’s agriculture and rural economy. Ensuring the sustainable development of agricultural crowdfunding is a key issue that needs attention against the current background. The concept of cohesion is introduced into the study of agricultural crowdfunding risk prevention, and the cohesion evaluation index system is determined with the help of the gray-rough set method, weights of which are determined by using triangular fuzzy hierarchy analysis. The TOPSIS method is used to evaluate it, four crowdfunding projects are selected for case studies, and the models are compared and analyzed. Finally, the influencing factors are comprehensively analyzed. The results show that: (1) The case evaluation results are consistent with its actual situation, and the comparison with the model presents the accuracy of the selected model, both of which verify the feasibility of the evaluation model. (2) Collaboration, organizational leadership, and the degree of assurance of the quantity and quality of agricultural products are important factors affecting the improvement of the cohesion in agricultural crowdfunding risk prevention. (3) The most significant factors in enhancing the cohesiveness of agricultural crowdfunding risk prevention are “responsiveness” and “safety of agricultural products”. Finally, the targeted countermeasures and suggestions are expected to provide the decision-making basis for the risk management of agricultural crowdfunding and realize the sustainable development of agricultural crowdfunding.
