State-owned enterprises refer to enterprises invested by the government and holding controlling shares. These enterprises play an important role in China's economic system, involving energy, finance, transportation, communications and other industries. A simple way to identify state-owned enterprises is to check the shareholder information of enterprises. If the government or state-owned capital holds a controlling stake, then the enterprise can be regarded as a state-owned enterprise.
Lianhai Chuangzhi is a private enterprise, not invested by the government, so it cannot be classified as a state-owned enterprise.
