In 2021，Beijing led the world in terms of the number and investment scale of multinational companies，and the effect of headquarters agglomeration is obvious，mainly in the service industry，with a high degree of two-way openness. Multinational companies have seen new development trends such as steady growth in investment growth，the landing of a number of national landmark major projects，and the expansion of investment fields. In the future，the investment of multinational companies will be greatly affected by the policies of various countries. The high-standard construction of the “two districts” will continue to play a role in attracting investment，and the multinational investment in the digital economy is expected to continue to grow. In order to promote the healthy development of multinational companies，it is recommended that Beijing continue to improve the global city index，create an upgraded business environment，improve the international investment attraction system around key areas and links，and speed up the introduction of foreign “high-calibre and top-notch” talents.
