The listing of the joint venture company you see may mainly come from two situations:
1. The company has issued foreign shares (commonly known as B shares) or listed on the overseas capital market as a domestic local listed company (listed in both places). If the number of shares held by foreign shareholders exceeds a certain proportion, it will be regarded as a joint venture (for example, more than 25% of the share capital).
2. After listing, the company issues foreign shares or (especially to overseas strategic investment institutions), resulting in foreign shareholders holding more than a certain proportion (such as 25%), and becomes a joint venture listed company.
Of course, there are other situations. After the reorganization of the original listed company, foreign shareholders are introduced, and the shareholding ratio exceeds a certain proportion, which is also considered as a joint venture listed company.
It is more reasonable for the joint venture company to list overseas, because on the one hand, it has foreign shareholders. If shareholders are well-known overseas, or even most of the company's business is overseas, overseas listing will have a positive impact on overseas investors' understanding of the company and its overseas reputation.
