Comprehensive national power (CNP), the most widely used index to comprehensively measure and represent the global or regional competiveness and influence of a country, plays a central role in international relations theory [1]. Previous theories consider that the growth of states means the extension of power radius and the expansion of living (interest) space (e.g., [2,3]). However, under the background of globalization, economic radiation, and political and cultural influences become the main means of states growth instead of land occupation. National power requires new interpretation and measurement under the background of sustainable development.
