数字化支付促进了农村居民消费升级吗？基于中国家庭金融调查（CHFS）数据的实证分析

挖掘农村居民的消费潜力、推动农村居民消费升级对实现乡村振兴目标和推动国内国际双循环具有战略意义。通过构建数字化支付影响农村居民消费升级的理论分析框架,并采用中国家庭金融调查数据进行验证,研究发现：数字化支付对推动农村居民消费升级具有显著积极影响,主要表现为数字化支付能有效降低商品消费的价格敏感性和资金约束,通过心理账户和消费信贷两条中介路径促进农村居民消费升级;不同资金来源的数字化支付对农村居民消费升级的影响效应存在差异,表现为基于活期储蓄的数字化支付较基于消费信贷的数字化支付对农村居民消费升级的促进作用效果更明显。由此建议聚焦数字赋能以改善农村数字化支付环境,创新消费信贷产品,不断提高农村居民收入,推动农村居民发展新型消费,释放消费潜力。     

技术创新、数字化投入与中国制造业国际竞争力

数字经济背景下,选择适宜的创新模式,与数字化转型有效协同,是发展中经济体参与国际分工并获得竞争优势的关键。基于2005—2018年中国16类制造业投入产出、进出口贸易等数据,实证检验了技术创新对中国制造业国际竞争力的影响以及数字化投入的调节作用。研究发现,自主创新对中国制造业国际竞争力产生了显著的正向影响,而模仿创新对中国制造业国际竞争力产生了显著的负向影响。数字化投入显著抑制了自主创新对中国制造业国际竞争力的积极影响,即在自主创新领域表现出“数字化创新悖论”;同时,数字化投入也抑制了模仿创新对中国制造业国际竞争力的消极影响,但作用并不显著。进一步分析发现,计算机、电子和光学设备数字化投入以及电信数字化投入的调节效应与全样本的回归结果基本一致,IT和其他信息服务数字化投入反而会强化模仿创新的消极影响。因此,数字经济时代,在不断提高制造业自主创新能力的同时,要格外注重增强数字经济与技术创新的契合度,快速提升中国制造业国际竞争力,实现行业高质量发展。     

数字经济发展的碳减排效应研究——基于223个地级市的实证检验

发展数字经济是有效降低城市碳排放强度的重要抓手。利用2016—2020年中国223个地级市面板数据,实证研究了数字经济发展对城市碳减排效应的影响。研究发现:数字经济发展能够降低城市碳排放强度;数字经济发展通过提高能源环境效率和推进产业结构高级化、合理化等渠道降低城市碳排放强度;战略性新兴产业创新能力加强了数字经济发展对碳排放强度的抑制作用。数字经济发展在降低城市碳排放强度的进程中存在双重门槛,只有在数字经济发展超过特定门槛值时,碳减排效应才会显著,且其效应呈现出递减特征。异质性分析表明,数字经济发展能降低非中心城市和非资源型城市碳排放强度,但对降低中心城市和资源型城市碳排放强度的影响不显著。因此,政府应积极抓住大数据、云计算、人工智能等“新基建”的发展机遇,夯实数字经济基础底座,实现城市碳减排。     

数字经济对我国市域农业经济韧性的影响效应与机理分析——基于系统GMM模型与动态门槛模型的检验

基于2011—2019年我国277个市域农业的面板数据,运用反事实方法科学测度了其经济韧性水平,并借助系统GMM模型、中介模型和动态门槛模型等方法,实证检验了数字经济对市域农业经济韧性的影响效应及作用机理。研究发现：数字经济显著增强了市域农业经济韧性,这一结论经一系列稳健性检验后仍能成立;机制分析结果表明,农业资本深化是数字经济提升市域农业经济韧性的重要路径。异质性分析表明,在东部、中部、西部地区和人力资本水平较高的地区,数字经济对市域农业经济韧性的影响效应更为显著,而对东北部地区的提升效应则不显著。动态门槛检验进一步揭示,数字经济对市域农业经济韧性的影响呈现边际递增的非线性特征,当数字经济发展水平越过特定门槛值（0147）时,数字经济对市域农业经济韧性的促进作用显著增强。     

数字经济塑造区域经济发展新动能新优势的实证研究——以成渝地区双城经济圈为例

基于2011-2020年成渝地区双城经济圈的相关面板数据,论证了数字经济对于区域经济发展的驱动效能。文章首先通过熵值评价法测算了成渝地区数字经济发展水平和区域经济发展水平的综合评价指数,然后运用描述性统计、ADF检验以及构建计量经济模型等方法对二者辩证关系进行了实证研究。研究发现,成渝地区的数字经济总体呈现波动上升发展趋势,并为区域经济发展提供了新动能和新优势;此外,政府参与程度越高,对于区域经济发展水平越具有正向增进作用。提出三点对策建议：充分发挥成渝双核的辐射作用,带动非核城市经济发展;提高数字经济发展水平,推动区域经济实现质的有效提升和量的合理增长;健全相关法律法规,保障区域经济安全与高质量发展。     

彝族传统民歌与流行音乐交汇的时代文化记忆研究

彝族传统民歌与流行音乐的交汇,影响了彝族时代文化记忆的表述。通过对彝族传统民歌与彝族流行音乐作比发现,不论是传统民歌,还是流行音乐,都体现了民族的时代思考与文化智慧。彝族传统民歌以生产生活和神话、历史等为基础进行编唱,倾向于描述场景或民俗文化,进而表达感情。彝族流行音乐则以传统文化为引,吸纳时代文化元素,借用流行音乐的要素创作,形成新型彝族民歌。在数智时代背景下,传统民歌与流行民歌呈现受众广、传播路径多元、形式多样等特点,并共同传唱民族文化。由此,彝族传统民歌与现代流行音乐的交汇,丰富了民歌的形式,影响了民族文化的时代表达。     

数字化媒体对铸牢中华民族共同体意识的影响及完善路径

在网络空间中,数字化媒体在推动各民族交往交流交融和铸牢中华民族共同体意识中发挥着愈加重要的作用。通过分析数字化媒体对各民族在网络空间中实现全方位互嵌共融的重大意义,剖析网络公民、媒体平台和数字政府在运用数字化媒体过程中对铸牢中华民族共同体意识造成的不良影响及其生成的法治原因,最终提出法律对策：应当完善网络公民铸牢中华民族共同体意识的法治宣传教育体系、构建数字化媒体平台铸牢中华民族共同体意识的法律责任机制、强化数字政府铸牢中华民族共同体意识的网络空间治理能力,从而在网络空间中发挥数字化媒体对铸牢中华民族共同体意识的积极效用。     

Effectively Evaluating the Accessibility of Electronic Monographs Using VPATs and Other Resources at the College of Staten Island Library- CUNY

Abstract

This study, building upon previous research work at the College of Staten Island (CSI) library, attempts to evaluate the accessibility of select digital monograph platforms and file formats utilized at the City University of New York (CUNY). The usability of CSI library’s locally developed ER-ACT tool to assist librarians with limited technical knowledge to review VPATs and to perform simple testing was also evaluated with challenges and successes reported. It was determined that the use of color-coded results in this study can help identify serious accessibility issues within ebooks and to communicate the results within libraries to assist with collection development decision-making. The study also includes a review of new court rulings related to accessibility issues in higher education and discusses where accessibility staffing reports in terms of job roles and duties held by university professionals. The testing of the accessibility of library ebooks, with various accessibility tools, are reviewed within the context of Section 508 revisions and new VPAT standards.     

The problem of intersectionality as an approach to digital activism: the Women’s March on Washington’s attempt to unite all women

ABSTRACT

This study examined the convergence of activism and intersectionality to understand how communicators create messages about social justice issues using social media. This is particularly relevant for public relations today, as digital activism almost ubiquitously involves bringing together conflicting publics who are active and social media-savvy, meanwhile maintaining an organizational brand/mission. Using the 2017 Women’s March on Washington (WMW) as an object of study, we explored how campaign messages reflected principles of intersectionality, consensus- and dissensus-based communication, and organizational self-reflection. We conducted a thematic analysis of posts from the WMW’s social media accounts as well as media quotes by the organizational leaders to get at the leaders’ intentions in their message design. Data suggested that messages of inclusivity as well as of necessary discord were employed to enact political change for WMW’s publics. We argue that although the WMW was not wholly intersectional, particularly in determining its political agenda, the efforts toward intersectionality are notable for theory-building and reflective practice, particularly for social mediated campaigns. The study proposes a theory for digital intersectional communication to guide future research and advocacy work.     

Digital learning across cultures: an account of activity theory

ABSTRACT

This paper explores a teaching and learning process as it unfolds in an online offshore classroom. The paper reports on teaching and learning narratives distilled from different cultures, namely the cultures of educators and students in the context of digital learning environments. Drawing on activity theory as a conceptual framework to analyse the narrative, we employ self-study as a methodological tool for capturing the dynamism and complexities that unravel in intercultural and technology-enabled teaching activities. The framework explores the relationships, tensions and opportunities of diverse activity elements that constitute the design and delivery of digital pedagogies. In the networked intercultural system, sustaining the position of activity elements and the specific relational circuit that they institutionalise is a key task for understanding digital technologies as an influential tool for effective learning and teaching practices. We argue that seeing the digital platform from the perspective of its role in creating dynamic interrelationships in a complex activity system is one way to move beyond the cultural confines of any particular element in the system.
