技术进步、技能需求与就业结构 --基于制造业微观数据的技能偏态假说检验

文章在对技术进步的技能偏态性理论回顾与总结的基础上,利用制造业企业的微观数据,用成本函数和生产函数形式的计量模型,对中国企业技术进步的技能偏态性进行了计量检验.研究结果表明,中国企业的技术进步在一定程度上呈现出技能偏态性的特点,导致了企业对高技能劳动力需求的增加,以及高技能劳动力所占的就业比重和收入比重的增加.同时,研究结果在一定程度上解释了劳动力市场中"技工荒"与"民工荒"并存的现象.     

动态视角下实时评论内容对直播电商商品销量的影响

实时评论是直播电商模式下一种新兴的用户生成内容,近年来,如何利用实时评论独特的动态互动体验提升消费者转化率成为学界和业界的讨论热点。总体看,已有关于实时评论影响效果的研究尚处于起步阶段,实时评论语义内容挖掘的维度仍较为单一,对实时评论内容动态特性的刻画也较为缺乏。从用户生成内容潜在的信息效应和说服效应出发,挖掘实时评论信息丰富度和情感极性两个关键的语义内容维度。基于动态视角刻画商品售卖区间内实时评论的信息丰富度峰值和情感极性峰值两个关键因素,探究其对直播商品销量的影响。构建实证模型,通过工具变量法解决模型内生性问题,并基于抖音平台的直播电商商品销售情况和实时评论数据进行假设验证。利用深度访谈法对实时评论的信息丰富度峰值和情感极性峰值影响消费者购买的心理机制进行分析。研究结果表明,直播电商模式下,实时评论的信息丰富度峰值对商品销量产生正向影响,证实实时评论具有信息效应;实时评论的情感极性峰值对商品销量产生正向影响,证实实时评论具有说服效应。进一步地,实时评论的信息丰富度峰值和情感极性峰值能够影响消费者决策过程中的关键心理状态,如产生关注和产生兴趣,进而推动消费者的购买行为。实时评论信息丰...     

宋代理学话语的形成

陈来认为,宋明理学之所以成为理学,全在于它形成了一套相对稳定的话语体系。深入细致地研究这一话语体系的形成过程,有利于总结和提炼中国学术思想话语体系的构型特性。杨国荣认为,对心性和体性的关注,构成了理学的重要特点。心性之学分别从人自身的存在和人与对象关系的维度展开了对意义的追寻。向世陵认为,宋代理学所创造的"成性"说奠定了理学的本体范畴,是儒学复兴的最重要理论标志;宋代理学本体论的创立使儒学在理论上真正获得了新生。孔令宏认为,宋明理学对道家、道教的吸收,丰富了儒学的体用合一论和功夫境界论,提升了儒学的哲理思辨水平,充实了儒家的思想体系,促进了儒学的新发展。     

Putting the individual and context back into national human resource development research: A systematic review and research agenda

Conceptualization of national human resource development (NHRD) emphasizes that it is an ongoing development process of the individual that is shaped by context. However, the extant literature has focused primarily on describing and evaluating NHRD policies and interventions in different countries with limited consideration of NHRD across the lifespan and the interaction of life stage with context. Using ecological systems theory (EST) and a lifespan development perspective (LDP), we present a systematic review of the NHRD literature based on 310 sources. We identify key themes and gaps in research across the lifespan and at distinct levels of the ecological system. We build on this review to suggest future research informed by both EST and an LDP. We propose a future research agenda focused on several key areas, including: the developing individual as the primary focus of NHRD; the dynamic relationship between NHRD microsystems and how this evolves over time; the exosystem and macrosystem, which provide the context of the NHRD development experience for the individual over their lifespan; and the imperatives of directing research attention to top-down and bottom-up influences within the ecological system. We also propose three methodological innovations to address many of the questions raised by our review, drawing on national archive databases, the use of historical methods and a focus on longitudinal data analysis. Finally, we highlight the practical implications of our analysis for ecosystem and microsystem NHRD actors.
