数字经济对水资源利用效率的影响——以黄河流域73个地级市为例

为探究黄河流域数字经济与水资源利用效率之间的内在关联,基于2011—2019年黄河流域73个地级市数据,利用超效率SBM模型测算各城市水资源利用效率。运用个体固定效应和中介效应模型,实证分析数字经济对黄河流域水资源利用效率的影响及作用机制。研究表明：数字经济发展能够显著提升黄河流域水资源利用效率,整体上呈现倒“U”型非线性影响关系;绿色技术创新在数字经济提升黄河流域水资源利用效率过程中发挥中介作用。据此,建议应适度发展数字经济,推动数字化和绿色化协同发展。     

数字普惠金融赋能粮食体系韧性——基于空间溢出效应视角分析

目的 探究数字普惠金融对粮食体系韧性的影响,为保障国家粮食安全,实现农业农村现代化指明新的方向。方法 文章基于2011—2020年全国31个省（市、区,不含港澳台地区）的面板数据,从抵抗能力、适应能力、变革能力3个维度出发构建粮食体系韧性综合评价指标体系,运用熵值法测算粮食体系韧性水平,利用空间计量模型实证检验数字普惠金融对粮食体系韧性的空间溢出效应和异质性。结果 数字普惠金融对粮食体系韧性具有显著的正向空间溢出效应,即数字普惠金融能够提升当地及邻近地区的粮食体系韧性;数字普惠金融的覆盖广度、使用深度和数字化程度均有助于粮食体系韧性的提升;不同区域的数字普惠金融对粮食体系韧性的影响差异显著,其中主销区数字普惠金融对粮食体系韧性的提升作用最大,主产区和产销平衡区次之。结论 应大力发展数字普惠金融,推动农村数字普惠金融基础设施建设,提高农户金融素养,创新金融服务模式和数字技术,因地制宜发挥各产区优势,并加强地区间的相互合作。     

数字普惠金融对农村内部收入差距的影响研究——基于生计资源多元化视角的经验分析

目的 在推进农民农村共同富裕道路进程中,识别数字普惠金融缩小农村内部收入差距的作用,并从农户生计资源多元化配置视角探索其作用机制。方法 文章合并使用县域数字普惠金融指数和中国家庭追踪调查数据（CFPS）,构造衡量农户收入不平等程度的相对剥夺指数,采用面板Tobit模型考察数字普惠金融对农村内部收入差距的影响,采用中介效应模型从生计资源多元化配置视角考察其作用机制。结果 （1）数字普惠金融能够有效减缓农户的相对收入剥夺程度,进而缩小农村内部收入差距,数字普惠金融指数每上升1%,农户相对收入剥夺水平下降7.87%,通过一系列稳健性检验后该结果依然可信;（2）生计资源多元化是数字普惠金融缩小农村内部收入差距的重要作用机制,数字普惠金融缩差效应的11.85%可由该作用渠道来解释;（3）数字普惠金融对农村内部收入差距缩减效应也具有明显的异质性,男性户主和45岁以下户主的农户、非农就业占比高和兼业化程度大的农户获得的数字普惠金融缩差“红利”更大。结论 作为新型金融供给方式,政府应大力推进农村数字普惠金融发展,因地制宜实施农村数字金融政策,鼓励农户生计资源多元化配置,多渠道应对风险提高收入水平,进而缩小农村内部收入差距助推共同富裕。     

A systematic literature review of the relationship between demographic diversity and innovation performance at team-level

ABSTRACT

Demographic diversity is a relevant aspect to consider when forming innovation teams, particularly where the labour market needs to be transformed in terms of age, gender and race (as in South Africa). Existing research reports mixed findings about the effects of demographic diversity on innovation performance of teams. This study contributes to the existing equivocal research by systematically reviewing the literature about the effects of demographic diversity and its dimensions on innovation performance of teams. Results show that high diversity of demographic dimensions, namely age, gender and culture increases team innovation performance when considered individually while the overall team demographic diversity has mixed effects. This review also confirms the existence and effects of various moderators that can be leveraged to develop team-formation policies such that the direct effects of demographic diversity and its dimensions on team performance can be influenced to foster the desired innovation performance.     

高端装备制造企业向智能制造转型过程研究——基于数字化赋能视角

智能制造是全球制造业的发展趋势，也是“中国制造2025”的主攻方向。本文基于数字化赋能视角，通过对“金风科技”和“陕鼓动力”的纵向双案例研究，探究高端装备制造企业智能化转型的动态演进过程。研究发现：高端装备制造企业向智能制造转型过程中，经历了数据存储、数据分析、数据融合三个阶段的演进过程。高端装备制造企业的差异化产品研发流程经历了产品生产销售、产品和服务整体解决方案，再到智能化整体解决方案的转变。数据采集分析能力、生产过程数字化能力、运营方式平台化能力是影响高端装备制造企业转型升级的数字化层面主要因素，且三种因素的演化推动了高端装备制造企业智能化转型从数据存储阶段到数据融合阶段的演进过程。研究成果丰富了高端装备制造企业智能化转型的基础理论，为推动高端装备制造企业智 能化转型提供理论依据。     

Skill development in reverse mentoring: Motivational processes of mentors and learners

Building on Murphy's (2012) model of reverse mentoring, we examine the psychological processes that contribute to skill development in initiatives where knowledge is transferred from younger to older individuals. We employ a sample of younger mentors (n = 457) and older learners (n = 293) participating in a digital skills initiative to test parallel moderated mediation models. Our findings show extrinsic motivation plays a dominant role in the development of younger groups' mentoring skills, while older learners' digital skills development is primarily driven by intrinsic motivation. We also find positive affect and self‐efficacy can serve as personal resources in this context, but only for mentors. Taken together, our results suggest motivational processes in reverse mentoring unfold differently for the two groups involved in the exchange. Recommendations for human resource practice, including specific guidelines for developing intergenerational learning initiatives, are discussed.     

陕西省数字普惠金融与经济高质量发展耦合协调关系

基于2011—2020年统计数据，通过构建经济高质量发展指标体系对陕西省10个市区经济高质量发展水平进行测度，并运用耦合协调度模型、空间相关性分析以及泰尔指数对陕西省数字普惠金融与经济高质量发展的耦合协调关系进行研究。结果表明：陕西省经济高质量发展与数字普惠金融变化趋势有较强的一致性，整体在时序上呈上升趋势，发展状况良好；二者耦合协调度在空间上发展不平衡，失调区域多分布于陕北和陕南地区，协调区域聚集在关中地区；陕西省耦合协调水平总体差异明显，差异主要来自区域内差异，同时关中地区的内部差异明显大于陕北和陕南地区。     

Resisting media marginalisation: Black women’s digital content and collectivity

ABSTRACT

Based on analysis of 23 interviews, this paper examines how social media and online content is implicated in the collective, resistant and transnational media experiences of Black women in Britain. It contributes to scholarship concerning race and the virtual marketplace by examining tensions between the countercultural, communal and commercial qualities of Black women’s online experiences. Drawing upon theorising of the oppositional spectator gaze of Black women, and narratives of technology consumption, we unpack how Black women’s digital activity can enable them to navigate the hegemony of US content, their marginalisation in British mass-media, and situate them within a Black experience that transcends Britain’s borders. Our work illustrates how Black women’s online encounters can be a source of resistance, Black digital commentary and community, as well as being subject to corporate co-optation. We conceptualise such online experiences as being shaped by transnational dimensions of the relationship between race, media and markets.
