Appropriate policy measures to attract private capital in consideration of regional efficiency in using infrastructure and human capital

Regional economic policy disposes of two principal options to attract private capital, which in turn helps to safeguard employment and to foster regional growth. On the one hand, regional policy could seek to enhance a region's level of public capital (e.g. transport infrastructure), which as a consequence makes the region more attractive to private investors in general. On the other hand, private capital could be attracted in a more direct way by proposing specific innovation, SME or cluster programs. The success of both options is partly driven by the regions already existing level of region specific production factors and the ability to use these factors efficiently. Indirect approaches to attract private capital seem to be particularly promising for efficient regions (no matter of the absolute level of public capital). In contrast, inefficient regions shall benefit more from specific programs. However, for Germany the factual pattern seems to be the other way around, which could widening rather than closing the income gap among regions.
