Your problem has its own problems. Central enterprises and state-owned enterprises are not juxtaposed concepts. Central enterprises are state-owned enterprises owned by the central government and are a kind of state-owned enterprises. The concept corresponding to state-owned enterprises is local state-owned enterprises. Central enterprises are all state-owned enterprises, but state-owned enterprises are not necessarily central enterprises.
The controlling shareholder of China Eastern Airlines is China Eastern Airlines Group, a state-owned enterprise directly supervised by the State Council SASAC. Jiangsu Branch of China Eastern Airlines is not an independent legal person, and its nature is the same as that of its parent company. Of course, it is also a central enterprise. Since it is a central enterprise, it is of course also a state-owned enterprise.
