Abstract:Rural small and medium-sized enterprises(SMEs) are an important carrier to promote digital agriculture and countryside in the digital economy. How to enable precise immunity through digital technology and improve the digital intelligence immunity of rural SMEs have become a hot issue of common concern to enterprises and academia. From the perspective of single and multiple configuration, Fuzzy Analytical Hierarchy Process(FAHP) is used to calculate the weight, Interval Number -DEMATEL method is used to calculate the centrality, and Fuzzy Set Qualitative Comparative Analysis(fsQCA) is used to study the configuration. The results show that the ability of digital intelligence perception, early warning, processing and review of crisis events, the ability of digital intelligence risk assessment and control of enterprises, the ability of digital intelligence recovery for normal operation of enterprises can have positive impacts on the improvement of digital intelligence immunity of enterprises. Then there are no necessary conditions that constitute the significant improvement of enterprise's digital intelligence immunity alone. At last, there are three types of driving configurations that significantly improve the digital intelligence immunity of rural SMEs. The significant improvement of enterprise digital intelligence immunity is the synergistic effect of many factors, and the effective combination of all factors works in the way of "the same destination". According to the results, the paper proposes the paths to improve digital intelligence immunity to find the correct direction of digital intelligence immunity for rural SMEs, and formulate digital intelligence immunity strategies, so as to improve the risk prevention and control ability of rural SMEs.
