This paper constructs the multi-dimensional model on synergic evolution of China's marine economic system oriented by high-quality development. Through the steps of order parameters selection, order degree of subsystems, and synergy degree of system, the results show: (1) From the dimension of industry, the order degree of marine primary and secondary industry shows “wave” growth, the marine tertiary industry shows “linear” growth, three subsystems are in “non-synergy” state, the primary industry has serious obstacles for development. (2) From the dimension of region, the order degree of three marine economic circles from high to low is “North, East, and South”, the southern one has late-developing advantage, three subsystems are in “non-synergy” state, the synergy between adjacent regions is greater than non-adjacent ones. (3) From the dimension of element, the order degree of three subsystems continues to rise and presents similar trajectory, while three subsystems are in “non-synergy” state with continuous downward trend. Furthermore, the policy implications are proposed from muti-dimension.
