Tough times, shifting roles: examining the EU’s commercial diplomacy in foreign energy markets
本文聚焦里海地区，研究欧盟如何越来越多地开展商业能源外交（即对外投资企业的政治支持），并解释成员国为何将这一角色委托给欧盟，尽管它们在对外能源政策上通常不愿合作。
Focusing on the strategically important Caspian region, this article demonstrates how commercial energy diplomacy – political support for foreign-investing businesses – is increasingly conducted at the European Union (EU) level. It explains why member states have delegated this role, despite a general hesitancy to co-operate in foreign energy policy and perceptions of a strong division between diplomacy-based and (EU-favoured) governance-based approaches to external energy policy. To explain this new role (and its limits), this article employs a functional–rationalist framework focusing on the structural demands of a more challenging international energy environment and EU-level supply factors (economies of scale, increased leverage and more neutral/less politicized position of the EU) that help respond to it. Overall, the article examines an important area of increasing EU foreign energy co-operation and demonstrates how energy governance and diplomacy are not necessarily competing approaches, but rather different tools for achieving a more secure investment climate for European companies.
