»Paradigm Shift in Foreign Trade Law. A Legal Examination of the Cross-Sectoral Assessment of Corporate Acquisitions«: This thesis examines the German cross-sectoral assessment of corporate acquisitions to evaluate the reorganization of investment control law and to assess from a legal policy perspective, whether the associated paradigm shift represents redundant protectionism or a necessary protection of public order or security. The initial point of the thesis is the European and German repositioning in industrial and economic policy, which is based on the protection of technological and industrial souvereignty.
