节前科创债供给缩量。本周（2026.2.9-2026.2.13，下同）科创债新增供给达 292.8 亿元，因假期因素主动减量，规 模较前一周明显收缩。发行结构以银行间 1 年内品种为主，亦有宁德时代等优质龙头 5 年期品种发行。新债认购方面， 科创债品种较普通信用债认购相对清淡，市场优先抢配高等级短久期品种，ETF 成分券标的更受机构青睐。 存量科创债评级呈现高度集中特征，AA+及以上隐含评级债券数量占比为 73.7%，AA 级中等资质个券占比也达到 22.1%， 反映部分中小科创主体融资需求；行业分布则以传统行业为主导，建筑装饰、公用事业、综合行业债券数量占比 38.8%， 纺织服饰、通信、非银金融行业较该行业全部信用债估值存在 16bp 以上的超额利差。 科创债品种内部比价方面，最新一周科创债指数成分券与非成分券的利差走阔至 27.1bp，银行间品种与成分券利差读 数也走阔至 8.5bp。拆分到 1-3 年，银行间品种与指数成分券存在近 20bp 的压缩空间。总的来看，节后科创债市场短 期将延续震荡格局，短久期高等级及 ETF 成分券表现占优，投资策略上可聚焦 1-3 年期 AAA 品种，较强的流动性便于 ...
