No, SDIC is a limited liability company (state-controlled), which belongs to the employment establishment of formal employees of state-owned enterprises. National Development and Investment Group Co., Ltd. is an important state-owned backbone enterprise directly managed by the central government, a wholly-owned central holding company, and the first batch of state-owned capital investment company reform pilot units. State-owned enterprises and enterprises are completely different. The career establishment is funded by the state and works in public institutions. The wages of employees of state-owned enterprises are funded by the enterprises themselves. Entering a state-owned enterprise means signing a labor contract and entering a state-owned enterprise. Admission is the main way to enter state-owned enterprises. Social registration posts are either very demanding or average. SDIC is not a public institution, and its personnel are contracted, so SDIC personnel are not civil servants. Civil servants are the units of the national unified entrance examination, and civil servants are civil servants. State investment is to sign labor contracts through recruitment, so the two are different, which is very different from civil servants.
