This study presents measures to evaluate the power of states from a network
perspective. Several indicators have been used for such analysis, including GDP,
GNP, and the CINC. However, these indicators have limitations in that they do
not take into account relational factors. Therefore, we provide three measures
developed from a network perspective at the macro, meso, and micro levels to
overcome these limitations. Furthermore, we explore the applicability of network
theory-based measurement by analyzing changes in network power in the United
States and China and present the following results. First, considering the economic
domain, we conclude that China has surpassed the United States at the micro level,
and the results of the centrality analysis indicate that the United States and China
are very close at the other two levels. Second, in the military trade and cultural trade
sectors, the United States has consistently been the most powerful state at all levels.
