ESG是衡量企业可持续发展的重要依据,对企业和社会都有重要的意义。文章采用2009~2022年中国A股上市公司ESG评级数据,研究了ESG表现对中国企业海外收益影响的机制与效应。研究发现,企业的ESG表现能显著提升中国企业海外收益,该结论在控制内生性和进行稳健性检验后依然成立。在影响机制方面,企业的ESG表现主要是通过促进绿色创新、提高商业信用与企业声誉、缓解投融资期限错配等路径推动企业海外收益提升。进一步分析发现,数字化税收征管、碳排放权市场交易、企业内部数字化转型等都会增强ESG表现对中国企业海外收益的积极影响。另外,企业ESG表现对海外收益的影响还存在“优于平均”效应,即企业ESG表现越是优于同群企业平均水平,越有助于企业海外收益提升,同时还有利于增强企业海外收益韧性。文章研究揭示了企业ESG表现影响海外绩效的路径机制,拓展了企业提升海外绩效及韧性的影响因素,为中国国际化企业积极践行ESG理念提供了理论依据和政策指导。

“俗”作为词体的天然属性,也是它与诗体的差异性所在。“世俗空间”书写既体现着词体的独特属性,也彰显着词体演变轨迹,是梳理词史的重要线索,宋词中的“青楼”与清词中的“江湖”书写正是两大关键阶段。宋词中的俗空间书写以歌楼庭院为核心,象征着世俗情爱空间,其中的“楼”与“帘”等意象书写以及赋体手法的层叠运用起到了重要作用;清词的空间书写则以江湖为中心,是世俗功名空间的映射,它以“孤馆”“孤舟”“窗”的意象书写为其特色,彰显着寒士词的苦涩与悲凉。从“青楼”到“江湖”,体现出宋清词对“私空间”书写的共同坚守。清词之所以有此嬗变,与清代独特的科举生态有着巨大关联。从宋到清,词体俗空间的差异性书写,既彰显宋清词经典美质的成因,也体现出二者正递嬗变的复杂关联。空间书写是透视词史演变的重要视角,同时也是中国传统诗歌研究中亟待深度挖掘的领域。
