自特朗普政府于2017年提出印太战略至2019年出台《印太战略报告》，印太战略已彻底取代奥巴马政府提出的亚太再平衡战略，成为美国在亚太地区的主流战略设计，随后，拜登政府又对此战略进行了新的调整。整体而言，印太战略继承了亚太再平衡战略的施策范围和战略目的，但是在战略前景和战略手段上却发生了重要转变。这种转变的主要原因在于美国战略自信的下降，美国国内社会危机的爆发，以及美国遏制强国传统的上升，个别地区国家的配合也减少了美国亚太战略转向的阻力。这一转向给亚太各方都带来了消极影响：中国周边地缘环境恶化，美国地区盟友、伙伴陷入多重两难，美国战略声誉受损，国际机制与全球化发展受阻，亚太地区从整体到局部无一受益。当此大局，中国应在保持战略定力的基础上在印太地区努力发挥建设性作用。
Since the Trump administration put forward the “Indo-Pacific Strategy” in 2017 and the “Indo-Pacific Strategy Report” in 2019，this strategy has completely replaced the “Asia-Pacific Rebalance Strategy” proposed by the Obama administration and has become the main strategic design of the United States in the Asia Pacific region. Subsequently，the Biden administration has made some new adjustments to this strategy. On the whole，the “Indo-Pacific Strategy” inherits the implementation scope and strategic purpose of the “Asia-Pacific Rebalance Strategy”. However，significant changes have taken place in strategic prospects and means. The main reasons for this change are the decline of American strategic confidence，the outbreak of American domestic social crises，and the rise of American tradition of coercing other powers. The cooperation of some regional countries also reduces the resistance to the strategic shift of the United States in the Asia Pacific region. This shift has had a negative impact on all parties in the Asia Pacific Region，including the deterioration of the geographical environment around China，the multiple dilemmas of U.S.regional allies and partners，the damage of U.S.strategic reputation，and the obstruction of the development of international mechanism and Globalization. Countries in the Asia Pacific region has benefited neither as a whole nor as an individual. Under this circumstance，China should strive to play a constructive role in the Indo-Pacific region on the basis of maintaining strategic stability.
