It is proposed that in a future Swedish investment screening mechanism, it will become mandatory for the Inspectorate of Strategic Products to consult with the National Board of Trade. A key role for the Board will be to contribute with analysis regarding the importance of the investment for the economy and the investment climate. We note a gap in the literature in the sense that the broad mass of economic analysis of foreign direct investments (FDI) focuses on the effects of production-oriented activities, while much of the security discourse also embraces ownership such as infrastructure and hospitals. It is shown that uncertainty is harmful to inward FDI. To minimize uncertainty and the potential FDI-dampening effects of an investment screening regulation, the range of affected sectors should be narrowly defined, accompanied by a swift and transparent review process that provides predictability to the transaction parties. Inward FDI in general and high-tech investments in particular can benefit innovation, stimulate investment, promote skill upgrading, improve resource allocation, sharpen competition, create high-wage jobs and increase economic growth. The literature has shown that many positive effects from FDI take place in the form of spillover effects that are difficult to measure directly. Many best practices attracting FDI include general policies rather than selective measures.
