概要 ミドルパワー国家の明確な定義は学者や研究者の間で意見が分かれており、一部大国との重複が見られるMehmet Ozkan. "A NEW APPROACH TO GLOBAL SECURITY: PIVOTAL MIDDLE POWERS AND GLOBAL POLITICS" Perceptions: Journal of International Affairs XI.1 (2006)。アメリカ合衆国、中華人民共和国、ロシア、イギリス、フランスは国際連合安全保障理事会における常任理事国であり、巨大な経済力や強大な軍事力、公式な核兵器の保有などから大国の地位にあると考えられている一方で、超大国とされるアメリカと中国を除きミドルパワーと扱う事例も存在する。日本とドイツは経済力の大きさから一般的には大国と考えられる。イタリアについては評価が分かれており、強力な経済力やG7としての地位から大国の一員であると考える学者もいる Why are Pivot states so Pivotal?.

The concept allows for distinguishing both strengths and weakness of India's globalist agency, shifting the analytical focus beyond material-statistical calculations to theorise behavioural, normative and ideational parameters.'Robert W. Bradnock, India's Foreign Policy since 1971 (The Royal Institute for International Affairs, London: Pinter Publishers, 1990), quoted in Leonard Stone, 'India and the Central Eurasian Space', Journal of Third World Studies, Vol. 24, No. 2, 2007, p. 183: 'The U.S. is a superpower whereas India is a middle power. A superpower could accommodate another superpower because the alternative would be equally devastating to both. But the relationship between a superpower and a middle power is of a different kind. The former does not need to accommodate the latter while the latter cannot allow itself to be a satellite of the former."Jan Cartwright, 'India's Regional and International Support for Democracy: Rhetoric or Reality?', Asian Survey, Vol. 49, No. 3 (May/June 2009), p. 424: 'India’s democratic rhetoric has also helped it further establish its claim as being a rising “middle power.” (A "middle power" is a term that is used in the field of international relations to describe a state that is not a superpower but still wields substantial influence globally. In addition to India, other "middle powers" include, for example, Australia and Canada.)'

The trilateral alliance known as the India, Brazil, and South Africa Dialogue Forum, or IBSA, exemplifies the trend … The three member countries face the same problems and have similar interests.

The reasons for this categorization are the nations' advanced political-economic stature as well as their significant contribution to international cooperation and development. India and Brazil have recently become considered middle powers because of their rise in the global arena—particularly with the emerging notion of BRIC (Brazil, Russia, India and China).'Tobias Harris, 'Japan Accepts its "Middle-Power" Fate'.

In this it finds itself in a situation similar to Australia, India, South Korea and the members of Asean.'
