Dear Ruggero, according to Sergei I think this could be an exercise and that explicit relocation could be embarrassing for most of the companies. On the other hand the only valuable source I think you could look for is from some Advisory Company like Gartner or some other big Consulting Company like Booz Allen (specialised in manufacturing). I guess you already looked at scientific paper database like sciencedirect ... isn't it?

Multinational companies may adapt production more flexibly than outright relocation (meaning shutting down a production unit or terminating a supplier contract). First, sometimes changes in the disaggregration of the value system (say, a value chain) may lead to relocating some, but not all production activities. Second, to the extent that their production network has some flexibility (excess capacity) external changes (e.g. foreign exchange) may induce them to shift some, but not necessarily all, production across their network of production facilities.
