工业4.0时代,数字化转型成为世界各国企业全力争夺的战略制高地。由于数字化转型的全局性和复杂性,作为描述和指导企业制定数字化转型战略实施工具的成熟度模型成为当下工业界和学术界开发研究的热点前沿。通过梳理数字化成熟度模型的相关文献,本文首先运用描述性统计分析方法,统计与归纳工业界和学术界开发研究模型的基本情况。其次,对数字化成熟度模型的概念定义、模型特征、要素原则等展开系统性归纳研究。再次,对数字化成熟度模型运用过程中存在的问题,以及模型应用领域的新扩展、评价测度的新途径、成熟度体系的新层面进行系统梳理。最后,从“点、线、面”三个层次构建数字化成熟度模型的开发研究框架,并讨论了未来研究方向。本文厘清了数字化成熟度模型的开发和研究脉络,系统阐释模型内部关键要素,为深化数字化成熟度模型的开发研究提供方向性指引,同时也为企业实践数字化转型提供了重要的认知性辅助和工具性参考。

本研究采用眼动跟踪技术探究“边听边读”输入对汉语二语学习者阅读加工过程的影响。实验通过比较中级汉语二语学习者和汉语母语者在“边听边读”和“只读”两种输入条件下的眼动指标,研究“边听边读”输入是否对阅读产生冗余效应。结果显示,二语者在两种输入条件下阅读的凝视时间、总阅读时间、注视次数和回视出次数均未出现显著差异;而母语者“边听边读”输入比“只读”输入的注视时间长,注视次数多,跳读少。在“边听边读”条件下,二语者和母语者对大部分词的注视均早于音频(即读早于听),但二语者的听读一致比例显著大于母语者,读早于听的比例显著小于母语者。研究结果表明,“边听边读”输入对汉语二语者的阅读没有产生冗余效应,听觉信息的呈现没有增加二语者的认知负荷。
