Promoting the revitalization of rural industries is of great significance to the realization of farmers’ income increase, agricultural development and rural prosperity. Taking 36 counties in Shandong Province as case samples, fuzzy set qualitative comparative analysis method was used to explore the linkage effect of different factors on rural industry development under the dimensions of technology, organization and environment. The results show that the single condition does not constitute the necessary condition for the prosperity of rural industry, and there are four paths for the revitalization of rural industry such as organization-environment type, organization-leading type, digital environment enabling type and comprehensive development type. Counties should give full play to government effectiveness, strengthen policy guarantee and financial support, and choose the path of rural industry revitalization according to local conditions.
