Here are some bullet points from Telles about key patterns (footnotes omitted):
- The United States is the largest recipient of global FDI with an inward FDI stock of $2.9 trillion on a historical-cost basis in 2014. On a current-cost basis, the United States’ FDI stock was more than three times larger than that of the next largest destination country in 2014.
- Investment in the United States remains strong; total stock of FDI in the United States grew at an average annualized rate of 6 percent per year from 2009-2014. ...
- Advanced economies, led by the United Kingdom, Japan and Germany, hold the largest FDI positions in the United States.
- Majority-owned U.S. affiliates of foreign entities affiliates produced $360.0 billion in goods exports in 2013, and are a catalyst for research and development in America, spending $53.0 billion in R&D and accounting for a record high 16.4 percent of the U.S. total expenditure on R&D by businesses.
- Majority-owned U.S. affiliates of foreign entities employed 6.1 million U.S. workers in 2013, up from 5.8 million in 2011, and generally provide compensation at higher levels than the U.S. average, at nearly $80,000 per U.S. employee in 2013 as compared to average earnings of $60,000 for workers in the economy as a whole.
- The U.S. manufacturing sector continues to benefit greatly from inbound FDI flows, as nearly 70 percent of FDI flows in 2015 and over one-third of jobs at U.S. majority-owned affiliates of foreign entities were in manufacturing in 2013.
The Telles report is focused on basic evidence of FDI inflows to the United States. For a global perspective, see "Snapshots of Foreign Direct Investment Flows" (September 8, 2015), or the wealth of data in the UNCTAD World Investment Report 2016, which is the canonical source for data on global FDI flows.
I would add that the growth of foreign direct investment fits with other emerging patterns in international trade. For example, companies that use global supply chains will often find it useful to have a substantial ownership share in many of the links of that chain--which means more foreign direct investment. When exporting services, it will often be useful to have a physical presence in the country where the buyers of those services are located, to improve both communication and marketing. Clearly, it is increasingly unwise to assume that because a good or services is produced in the geographical area of a certain country, it is also being produced by a company that is owned by investors from that same country.
