Abstract: Based on the perspective of “agricultural production efficiencyagricultural ecological environmentagricultural management” composite system (hereinafter referred to as PEM system), the research on the development level, spatial pattern and coupling synergy level of agricultural modernization in Jiangsu Province is of great significance to the overall transformation and efficiency of agricultural modernization in Jiangsu Province. The coupling coordination degree model is comprehensively used to analyze the agricultural modernization level of 13 prefectures and cities in the province and the coupling coordination scheduling of PEM system. The elasticity coefficient model is used to evaluate the dependence between the agricultural modernization level of Jiangsu Province and each subsystem of PEM from 2006 to 2018. The results show that the average score of agricultural modernization level in Jiangsu Province has increased from 0.05 to 0.14, with an average annual growth of 1.09%. The highlevel areas are always five cities in southern Jiangsu, and the lowlevel pattern shows the trend of advancing from Central Jiangsu to northern Jiangsu and from coastal to inland. The coupling degree and coordination degree of PEM system in Jiangsu Province increased from 0.99 and 0.37 in 2006 to 1.00 and 0.38 in 2018 respectively. The average coupling degree of PEM system decreased from 0.57 to 0.54, with a decrease of 5.56%. The characteristics of shock differentiation are obvious. The order of dependency level between agricultural modernization and PEM subsystems in various cities is agricultural ecological environment subsystem > agricultural operation and management subsystem > agricultural production efficiency subsystem, and the dependency type with PEM system changes from single to diverse. It is proposed that we should focus on the coordinated and differentiated development of agricultural modernization among different cities and the precise policies for the development of PEM subsystems based on our own resources and development deficiencies.
