产业政策与中国数字经济行业技术创新

本文利用2008-2017年沪深A股中数字经济上市公司的专利及财务数据,分析了政府补贴、税收优惠、信用贷款、行业准入制度四类产业政策对数字经济行业技术创新的影响。估计结果表明, 政府补贴和行业准入制度对数字经济行业专利申请和专利发明的影响显著,税收优惠、信用贷款对数字 经济行业技术创新的影响相对不明显。对数字经济行业细分类别进行稳健性检验结果表明,政府补贴和行业准入制度依然是影响数字经济行业技术创新较为显著的产业政策,产业政策对数字经济行业技术创新的影响存在行业异质性。政府补贴对电信传媒和软件信息行业专利申请和发明的影响更为显著,行业准入制度对软件信息行业的影响更为显著。此外,政府补贴和信用贷款均能通过提高企业研发投入来提升企业创新能力, 行业准入制度和税收优惠均能通过提高企业利润而提升企业创新能力。本文为政府制定数字经济行业技术创新激励政策提供了经验证据,有助于政府制定合理的产业政策促进 数字经济行业技术创新。

中国数字经济产业统计分类问题研究

数字经济在推动经济增长和转变人们生活方式方面发挥了重要作用,已成为推动中国经济高质量发展的“新引擎”。然而,中国数字经济统计研究明显滞后于数字经济发展实践,这不利于相关部门监测数字经济发展和科学制定政策。本文系统梳理了数字经济的概念演进以及经济合作与发展组织、美国经济分析局等国际组织和官方统计部门对数字经济相关产业的统计划分。结合中国已有相关统计分类标准,提出了中国数字经济产业统计分类,具体包括数字设备制造、数字信息传输、数字技术服务、数字内容与媒体、互联网应用及相关服务5个大类,共计22个中类、122个小类,并与国际上现有的相应产业分类进行了对比分析。本文可为官方统计机构建立数字经济产业统计分类标准、统计和发布相关统计数据提供理论参考。     

Branding the self as an “authentic feminist”: negotiating feminist values in post-feminist digital cultural production

Freelancers who produce creative content online work in an increasingly precarious neoliberal economy, which requires self-branding, self-promotion, and constant audience engagement to succeed. Creating feminist content in a digital environment thus requires the negotiation of individual self-branding and promotional activities alongside the advancement of collective feminist politics. In this study, interviews with 11 feminist online writers reveal that they reconcile the individualistic undertakings required to succeed in the digital economy and their collective feminist values in three ways. Firstly, they incorporate “authentic feminism” into their personal branding endeavors; secondly, they redefine feminism to more closely match the values of post-feminism; and, thirdly, they advance peripheral collective goals in their creative communities. It is through these strategies that feminist values are negotiated and reworked, enabling producers to succeed as feminists in a digital economy that is more closely aligned with post-feminism.     

The Value of South and Southeast Asian Studies Journal Rankings

Abstract

This article ranks South and Southeast Asian Studies journals along three categories—quality, efficiency, and impact. The ranking summarizes the results of a survey sent to an international sample of South and Southeast Asian Studies scholars. This study is valuable in three ways: as a decision making tool for the South and Southeast Asian Studies academic community, as an evaluation of methodology in journal ranking studies, and as a discussion of the value of journal rankings studies to assessment and evaluation in higher education generally.     

PROMOTING SCHOLARSHIP THROUGH DESIGN

How can new media positively transform scholarly practices? One possible way is for scholarly archives such as e-journals and digital libraries to better support the needs and practices of their users, instead of the publishing process. This article examines what it might mean to promote cognitive and social aspects of 'scholarship' through innovative archive design. Design requirements for supporting both scholarly tasks and scholarly communities are derived by analysing existing cognitive and social theories. A theoretical framework for guiding archive design is introduced: the contextually enriched document framework. This framework suggests that: document interfaces should enable practitioners to progressively enrich documents with important contextual information arising from social processes; and archive managers should engage in proactive practices to facilitate use and assist practitioners in realizing the benefits of the new technology. Both the design requirements and the framework are illustrated with examples from an existing electronic journal - The Journal of Interactive Media in Education .     

NEW MEDIA AND DISTANCE EDUCATION: AN EU-US PERSPECTIVE

This paper presents an overview of the development of new media in the secondary and higher education systems of the European Union (EU) and USA. A combination of driving forces in pedagogical thinking, technological progress and business models have raised new expectations for the wide-spread use of educational technology, such as by providing major market opportunities as in the adult training segment. Many public sector and private commercial initiatives for connecting schools to the Internet, first adopted in the USA, and then in member states of the EU, have met with marked success. Most of the secondary schools are, or are being, wired, if but to a limited extent. The diffusion of information and communication technologies (ICTs) in the EU schools is particularly rapid given their initially low penetration rate. If American organizations are indeed leading the development of online courses and programmes in the higher education sector, European universities have now realized the importance of investing in this field. However, for new media to significantly improve the educational process in the EU and in the USA, they must be embodied in the complex school or university environment, and be nurtured by new partnerships between business and the academy.
