Abstract：Solidly improving the modernization level of the agricultural industrial chain and supply chain is an important choice to empower the high-quality development of the rural economy. The dynamic panel model and mediation effect model are used to analyze the panel data of 30 provinces in China from 2011 to 2020；and the relation among rural three industries， agglomeration of producer services，and modernization of agricultural industrial chain and supply chain is explored. Empirical evidence shows that：the integration of rural three industries has a significant driving effect on the modernization of the agricultural industrial chain and supply chain，and presents a heterogeneous distribution pattern of "eastern>northeastern>central> western region" at the spatial level ；the intermediary effect test shows that the agglomeration of agricultural producer services plays an intermediary role in the process of modernization of agricultural industrial chain and supply chain driven by the integration of rural three industries，and the effect accounts for 13.47% ；compared with specialized agglomeration，the intermediary effect of diversified agglomeration of agricultural producer services is more significant ；in addition，the regional heterogeneity test shows that the mediating effect of agricultural producer services industry agglomeration accounts for the eastern，central，northeastern and western regions. Based on this，it is recommended that the government should drive the integration of rural three industries through digital transformation and establishing the pattern of platforms ；the industrial association should promote the diversified agglomeration of producer services through establishing pilot zones ，constructing national platform，and formulating pilot projects to provide agricultural industrial chain and supply chain with support ；and we should give play to the role of government and producer services in eastern regions in leading the western ，central and northeastern regions to realize the modernization of agricultural industrial chain and supply chain.
Key words：modernization of agricultural industrial chain and supply chain ；integration of rural three industries；agglomera⁃ tion of producer services industry；specialization agglomeration；diversified agglomeration
