“印太经济框架”(IPEF)是美国“印太战略”在经济贸易领域的主要抓手。自美国总统拜登于2021年10月在东亚峰会上正式提出IPEF以来,其进程一直处于快速发展中,尤其联通的经济、韧性的经济、清洁的经济和公平的经济四大支柱的谈判突飞猛进。IPEF虽然不是传统意义上的自由贸易协定,但其在经济贸易议题上的内容却越来越具体,新趋势、新动向也日趋呈现。文章采用比较研究方法,对IPEF与TPP、RCEP、APEC等亚太区域合作贸易议题进行比较,认为IPEF贸易议题具有战略性和前瞻性,并分析其对亚太区域合作产生的冲击,可能改变20世纪60年代以来亚太地区形成的区域合作机制。为降低IPEF对中国造成的负面影响,中国应深化改革、扩大开放,并推动亚太区域合作机制与贸易议题创新,深化亚太区域合作。

低保制度作为中国社会救助体系中兜底性的核心制度安排,在实践中捆绑了大量的救助资源,这导致低保对象和其他低收入群体间的收入差距出现扩大的趋势,不利于增强“提低”效果和推动共同富裕。本文基于中国家庭追踪调查和中国家庭金融调查的样本数据,运用模糊断点回归的方法实证检验了不同时期农村低保制度的捆绑效应,并进行了政策模拟分析。结果发现,低保捆绑效应在脱贫攻坚时期不断放大,低保家庭获得的专项救助远高于其他低收入家庭,其中在危房改造、医疗健康和教育补助方面的差异尤为明显。进一步政策模拟发现,将低保捆绑的其他社会救助全部或部分转移至其他低收入群体,可以在不增加财政负担的前提下,缩小低收入群体内部的收入差距,提升社会救助的有效性。因此,本文建议打破低保的捆绑效应,更好地发挥社会救助的“提低”作用。
