Abstract: Rural Industrial Integration Development Demonstration Parks is an important carrier to promote industrial integration, and has the function of cohesion and integration. This paper selects 316 demonstration parks of China’s rural industrial integration development as research units, and uses spatial analysis methods and geographic detector models to explore their spatial distribution characteristics and influencing factors. The results show that: (1) China’s rural industrial integration development demonstration parks are mostly located in East China, and they are spatially cohesive and distributed; on the whole, they show the density distribution characteristics of “small agglomeration and large dispersion” and fractal features of “significant differences in grid dimensions and complex spatial structure”. (2) Seven factors, including the total output value of agriculture, forestry, animal husbandry and fishery, the number of cooperatives integrating production, processing and marketing, and the main business income of the agricultural product processing industry, have a significant positive impact on the number of demonstration parks for the integrated development of rural industries in China. (3) The influence of seven factors, including the total output value of agriculture, forestry, animal husbandry and fishery, and the number of integrated production, processing and marketing cooperatives, on the distribution of demonstration parks for the integrated development of rural industries has spatial differences and there is a two-factor enhanced interaction. Among them, the number of leisure agriculture and rural tourism demonstration counties has the most obvious enhancement effect on other factors.
