Domestic structure and sub-national foreign policy: an explanatory framework

Purpose - This paper aims to examine the effects of domestic structure forces on “sub-national” foreign policy (SFP); an analytical concept provides a suitable operational framework for research on international activities of sub-national entities or regions. Design/methodology/approach - The paper is carried out on the basis of a theoretical framework proposed by the author. First, the dependent variable is defined. Then, domestic structure is broken down into four variables, including legal grounds, the level of autonomy, the type of intergovernmental relations and institutionalization. A comparative method is used to examine the validity of the theoretical framework. Findings - The paper finds out that domestic structural forces influence level and form of SFP with some regularity. The influence of these forces on SFP can be explained, as they recur and have such consistent effects that they create patterns and regularities in SFP. Such regularities can be detected through systematic analysis. Originality/value - The topic of SFP is relatively controversial because of academic debate over international agency of substate actors. However, it is a worthwhile subject of research, as it has the potential to revolutionize research in foreign policy analysis. Moreover, the phenomenon of SFP is in need of theorizing and comparison as the literature on SFP is still in its infancy.
