Let's first understand the following points:
1. In English, besides company and Corporation, there are many other ways to express company.
2. In China, according to the number of shareholders and promoters, the company law stipulates two kinds of companies, namely limited liability company (hereinafter referred to as "limited company") and joint stock limited company (hereinafter referred to as "joint stock company"). Among them, limited liability company is divided into listed and non listed companies.
有限责任公司，一般翻译成为“Co., Ltd.”或 “Ltd.”, 即limited Liability Company；
Limited liability company, which is generally translated as "Co., Ltd." or "Ltd.", that is, limited limitation company;
股份有限公司（非上市），根据英国写法，可以翻译为“Co., Ltd.”或 “Ltd.”，也可根据美系写法翻译成“Inc.”，即incorporated，原形是corporation；
A company limited by shares (unlisted) can be translated into "Co., Ltd." or "Ltd." according to the British writing, or "Inc." according to the American writing, which is incorporated, and the original form is corporation;
股份有限公司（上市），可译为“PLC”，即public limited company，更多的是偏向按照美系写法翻译为“Inc.”。
Limited company (listed), which can be translated as "PLC", or public limited company, is more inclined to be translated as "Inc." according to the American style.
3. In addition, there are many other companies of different nature.
合资公司，可译为joint venture （JV），但很少用在具体的公司名称中；
Joint venture (JV), which can be translated as joint venture (JV), is rarely used in specific company names;
合伙公司，一般译为partnership，常见的是有限责任合伙公司(LLP, Limited Liability Partnership)；
Partnership is generally translated as partnership, and LLP (limited liability partnership) is a common one;
Industrial companies are generally translated as industries or industrial company / corporation;
Group company, in which "group" is generally translated as group, and the latter "company" can be translated according to the specific nature of the company.
