To which places does Foreign Direct Investment (FDI) flow? How much FDI received a region in a given year? Answers to such questions are crucial to understand how regions can benefit from FDI, but data to answer them is often missing. In a project co-funded by the European Commission, the OECD works with experts from National Statistical Institutes and Central Banks to fill this knowledge gap by leveraging existing datasets and creating new ones.
Measuring Foreign Direct Investment in Regions
How can Foreign Direct Investment in regions be measured? What are the economic opportunities and potential risks associated with it and how are they distributed?

About
Context
FDI flows measure the value of direct investment during a given period. FDI stocks capture the accumulated level of direct investment at a given point in time. An important part of FDI are equity-based investments that can come as greenfield FDI or brownfield FDI. Greenfield investments are those where a firm sets up or expands their business operations abroad, whereas brownfield investments are those where a firm acquires a significant ownership share of an existing firm abroad. This project uses both official data on FDI flows and stocks as well as commercial data capturing greenfield and brownfield investment to understand how FDI and the related economic opportunities are spatially distributed.
Subnational FDI statistics in large (TL2) regions (2012-latest available year)
16 OECD countries collect subnational FDI flows or FDI stocks data as of 2023. The distribution of FDI in these countries is very concentrated. Across countries with available data, large (TL2) OECD regions where the capital city is located account on average for 45% of total FDI inflows, and 49% of FDI inward stocks. The percentage is higher for brownfield investments (56%) than for greenfield (29%). A better understanding of what type of investment flows in which region can help national and local policy makers leverage more effectively specific types of FDI for regional development.
