A bilingual comparative portrait of the United States, the European Union, China, ASEAN, Brazil, Russia, India, and Africa — measured across seven dimensions that shape how billions live, trade, govern, and imagine. 一部双语对照的世界地理政治图谱。以美国、欧盟、中国、东盟、巴西、俄罗斯、印度、非洲为八大板块，沿经济、行政、政治、科技、生活、消费、购买力七条经线，展现数十亿人如何生活、贸易、治理与想象。
To compare is not to equate. Each entity is a civilisation-unit of its own scale, with its own ledger of wealth, its own grammar of power, and its own appetite for the future.
比较并非等同。每一板块皆自成一文明量级，各有一本财富账簿、一套权力语法、一腔对未来的胃口。— Editorial Note · 编者按 — 编者按

Each dimension is aggregated from 4–7 sub-indicators, min–max normalised to a 0–100 scale. The leading entity on each axis does not necessarily score 100 — the ceiling reflects a theoretical maximum, not the current frontier. 每一维度由 4–7 个子指标加权汇总，按最大最小法归一为 0–100。各轴最高者未必得满分 — 顶值代表理论上限，而非当前领先水平。
The eight entities are not commensurable in kind. A federal state (US), a supranational union (EU), a civilisation-state (CN), a bloc (ASEAN) and a continent (Africa) all appear side by side. Readers should treat each card as a portrait, not a ranking. 八大板块在类别上并不同构。联邦国家（美）、超国家联合（欧）、文明国家（中）、国家集团（东盟）与整片大陆（非洲）并列呈现。读者宜将每一版视作肖像，而非名次。
