In 2019，under the background of the decrease of overseas investment and mergers and acquisitions，Chinese enterprises’ overseas M & A investment continued to decline in total volume and scale，but the layout in the high-end field of the global value chain continued to develop well，and Chinese enterprises’ investment along the “one belt and one road” continued to develop rapidly. In 2020，it is expected that the trend of China’s overseas M & A investment will pick up. We should grasp the investment opportunities brought by the era of scientific and technological innovation and carefully choose the investment direction and industry，and truly introduce overseas high-quality resources for our own use.
