近年來，中美兩強權在印太地區的戰略競爭愈演愈烈。特別是在基礎建設上，所謂的聯通性戰略，更是兩國在印太地區較量的指標。隨著經濟的快速發展，印太地區對數位化所需的基礎建設越顯急迫。在新冠疫情後，印太國家更加關注高質量的網路基礎設施以及一些關鍵的數據驅動技術，包括人工智慧（AI）。因應此需求，中國早在「一帶一路」（Belt and Road Initiative, BRI）的旗幟下，提倡「數位絲綢之路」（Digital Silk Road, DSR），積極推進數位基礎設施合作。美國則提出了「自由開放的印太戰略」（Free and Open Indo-Pacific Strategy, FOIP）和「全球基礎設施和投資夥伴關係」（Partnership for Global Infrastructure and Investment, PGII），並通過與盟友和夥伴建立網絡化聯盟，在基礎設施領域與中國展開競爭。基礎設施的競爭凸顯了中美戰略競爭的關鍵特色：強調發展與安全的緊密關係。

In recent years, the strategic competition between China and the United States in the Indo-Pacific region has intensified, particularly in the realm of infrastructure development. The concept of connectivity has become a key indicator of this competition, as both countries seek to expand their influence in the region. With the rapid economic growth, the demand for digitalizationrelated infrastructure in the Indo-Pacific region has become increasingly critical. In the post pandemic period, Indo-Pacific countries are more concerned about high-quality Internet infrastructure and some key data-driven technologies, including artificial intelligence (AI).

In response to this demand, China, under the banner of ‘Belt and Road Initiative’, has been promoting the Digital Silk Road (DSR) and digital infrastructure cooperation. The U.S., on the other hand, has proposed a ‘Free and Open Indo-Pacific Strategy’ (FOIP) and a ‘Partnership for Global Infrastructure and Investment (PGII),’ aiming to counter China’s influence in the infrastructure sector by forming networked alliances with allies and partners. This infrastructure competition underscores a fundamental aspect ofthe U.S.-China strategic rivalry: the interconnectedness of development and security.

In light of this, the article draws attention to ‘infrastructure statecraft’, which conceptualizes infrastructure investment as both a power resource and a strategic tool, while exploring its limitations. Against the backdrop of U.S.-China power rivalry, the paper analyzes the effects of their competition in digital connectivity on the Indo-Pacific region, utilizing an ‘infrastructure statecraft’ framework, supplemented by strategic narrative theory and qualitative analysis based on primary and secondary data.

First, the paper centers on clarifying the evolution and development of the U.S.-China power rivalry in the Indo-Pacific region. Second, deriving from the fundamental concepts of ‘economic statecraft’, the section explores and explains the connotations of ‘infrastructure statecraft’, with particular emphasis on the importance of strategic narrative, which serves as the theoretical framework for the paper. Next, the focus is on examining China’s DSR and the U.S. PGII initiatives, comparing the strategic narratives, fundamental similarities and differences, strengths and weaknesses, and regional impacts of the two projects. Finally, it concludes with a perspective on the future outlook of the digital order in the Indo-Pacific region.
