Equity is the shareholder's investment share in a start-up company, that is, the equity ratio. The size of the equity ratio directly affects the shareholders' voice and control over the company. It is also the basis for shareholders to obtain economic benefits from the company, participate in the company's operation and management, and share dividends. Although equity cannot be completely equal to ownership, it is the core content of ownership. The investor with equity is the owner of the property. Equity cannot exist alone without legal person property rights, nor can legal person property rights exist alone without equity.
