王宏志的《龙与狮的对话:翻译与马戛尔尼访华使团》是首部从翻译角度研究马戛尔尼使团的著作,不仅重构了早期的中英外交关系,还为中国近代翻译史研究提供了重要参考。基于对该书的阅读与思考,本文指出,翻译在中国近代外交活动中作用巨大、影响深远;从翻译的视角重审外交事件,过往的“史实”和“史观”也许会发生偏离或反转;翻译史研究需继续加强对原始材料的搜集和考证工作,采用问题导向、文本整体细读、多元互证等方法,还原翻译现场;目前外交翻译史的研究任务主要包括拓展研究面向、反思翻译研究的基本问题、建构历史与翻译的互动关系。

数字化转型关乎企业人力资本结构升级,同时也是推动经济社会发展的重要引擎。本文基于上市公司2011—2021年数据,利用机器学习的方法衡量企业数字化转型程度,实证检验数字化转型对企业人力资本结构的影响及传导机制。研究结果表明,数字化转型显著提升了企业人力资本结构水平,并且存在一定程度的异质性。具体来说,对非制造业企业、信息传输、软件和信息技术服务业行业以及人均创收小的企业更加明显。同时,借助多期倍差法和工具变量法等手段进行内生性和稳健性检验后,该结论仍然成立。传导机制研究结果表明,数字化转型主要通过发挥技术进步效应、公平竞争效应和规模扩张效应实现企业内部人力资本结构升级。本文的研究有助于企业进行人才战略布局,形成人才发展重要支点,同时也为数字化转型促进人力资本结构优化提供了微观证据,对数字化战略相关政策的制定和新时代经济高质量发展提供相关启示。
