Abstract:

Frontier is an objective geospatial entity for the existence and development of a modern country, which provide fundamental practical significance for the country's long-term stability and prosperity. In the evolution of human society, the human social community established a modern country on a frontier with fixed geographical boundaries. However, as human beings' ability to explore the world has expanded due to changes in cognitive ability, science and technology, and economic globalization, the country has The shape of geographic boundaries has also undergone profound changes. The geographic boundaries of modern countries have expanded from traditional geographic spaces in territories, offshore, and near-space to modern geographic spaces such as deep seas, oceans, outer space, polar regions, and information. In general, the changes in the morphological characteristics of modern national boundaries are mainly manifested in the changes from a two-dimensional space to a multi-dimensional space, an extension from a deterministic space to an uncertain space, a development from a geographical space to a space of interest, and a space from sovereignty. Expand to strategic space. Under the premise that the geographical boundaries of modern countries have changed, China has proposed the governance principles of peace, sovereignty, inclusiveness, and co-governance to govern the frontier of international relations. This not only contributes to the governance of the frontier of international relations, China's wisdom, but also effectively promoted China's territorial governance to a higher level.

摘要：

领土疆域是现代国家存在和发展的客观地理空间实体，对国家的长治久安和繁荣稳定具有根本现实意义。在人类社会发展的演进历程中，人类社会共同体在有着固定地理边界的领土上建立了现代国家，然而随着人类探索世界的范围因认知能力、科学技术及经济全球化等变化而扩展，国家地理疆域的形态也由此发生了深刻变化。现代国家的地理疆域已经从领土、近海和近空传统地理空间，向深海、远洋、太空、极地和信息等现代地理空间延展。总的来看，现代国家疆域的形态特征的变化主要表现为，由二维空间向多维空间的变化，从确定性空间向不确定空间延展，从地理空间迈向向利益空间发展，从主权空间向战略空间扩展。在现代国家的地理疆域已经发生变化的前提下，中国在构建人类命运共同体中提出了以和平、主权、普惠、共治为治理原则来治理国际关系新疆域，这不仅为治理国际关系新疆域贡献了中国智慧，也有效推动了中国疆域治理迈向更高台阶。
