Whether chlor-alkali chemical enterprises belong to state-owned enterprises depends on their specific shareholding structure. In China, some chlor-alkali chemical enterprises are established by state-owned enterprises or state-owned holding companies, which can be regarded as state-owned enterprises. For example, Shanghai Chlor-Alkali Chemical Co., Ltd. is a state-controlled listed company, which was restructured from 1992 state-owned super-large chlor-alkali enterprise, so it can be considered as a state-owned enterprise.
However, not all chlor-alkali chemical enterprises belong to state-owned enterprises. Some enterprises may be established by private enterprises or foreign-funded enterprises, and these enterprises are not state-owned enterprises. For example, although Guangxi Huayi Chlor-Alkali Chemical Co., Ltd. is not a state-owned enterprise, it is a secondary subsidiary of Shanghai Chlor-Alkali Chemical Co., Ltd., a state-controlled listed company.
