A one-person limited liability company refers to a limited liability company with only one natural person shareholder or one corporate shareholders (Article 57 of the Company Law). A one-person limited liability company is referred to as a one-person company, a wholly-owned company or a joint stock limited company for short. It refers to a limited liability company in which a shareholder (natural person or legal person) holds all the capital contributions of the company. China's "Company Law" stipulates that "a natural person can only invest in the establishment of a one-person limited liability company. A one-person limited liability company cannot invest in the establishment of a new one-person limited liability company. One-person limited liability company has no shareholders' meeting; A one-person limited liability company shall make financial and accounting reports at the end of each fiscal year, which shall be audited by an accounting firm. If the shareholders of a one-person limited liability company cannot prove that the company's property is independent of the shareholders' own property, they shall be jointly and severally liable for the company's debts. " 1, with one shareholder. The investor of a one-person company has only one shareholder. Shareholders can be natural persons or legal persons. This is the difference between a one-man company and a general limited liability company. Usually, a limited liability company has two or more shareholders. This feature of one-man company also reflects the difference between it and sole proprietorship enterprises. The investors of sole proprietorship enterprises can only be natural persons, not including legal persons. 2. Shareholders shall bear limited liability for the debts of the company. The essential characteristics of a one-man company are the same as those of a limited company, that is, shareholders are only liable for the debts of the company to the extent of their capital contribution, and the company is independently liable for all its assets. When the company's assets are insufficient to pay off debts, shareholders shall not bear joint liability. This is the essential difference between a one-man company and a sole proprietorship enterprise. 3. Simplification of organizational structure Because a one-person company has only one investor, there is no shareholders' meeting. The functions and powers exercised by the shareholders' meeting in the Company Law shall be exercised by the shareholders alone in a one-person company. As for whether a one-person company should set up a board of directors and a board of supervisors, it is stipulated in the articles of association that it can be set up or not, and there is no law that it must be set up.
