数字经济视角下的新《证券法》——修订解读、实施支撑与未来展望

新《证券法》直接体现了数字经济的内容，主要有：将对客户保密制度升级为投资者个人信息保护制度，明确信息披露的载体包括证券交易场所网站，规定证券登记结算机构可以提供信息服务，在证券交易方面大幅度增加电子化交易的内容，尤其是新增了程序化交易和信息技术系统服务机构，等等。当然新《证券法》在信息技术系统服务机构和程序化交易方面需要进一步细化。而诸如互联网、云计算、大数据等数字技术都是数字经济时代的新型技术，它们虽然没有规定在新《证券法》中，但却对于新《证券法》的实施具有重要意义。未来包括投资性众筹、智能投顾和区块链结算在内的数字经济内容将会在新《证券法》的进一步修改中得到更多体现。     

中国数字政府建设的理论框架、研究议题与未来展望

数字政府建设受到持续关注,但如何理解和建设数字政府还缺乏共识。中国数字政府建设需要关注数字政府的概念化和建设水平评估、组织间数据共享与业务协同、政商关系与数字政府共建、数字政府建设水平的影响因素、数字政府的用户使用和合供五大关键问题。绩效评估、数据共享、政企共建、影响因素和用户使用,是未来数字政府研究需要关注的主要方向和研究路径。围绕共建、共享、共用、共治的建设目标,全面推进数字政府建设。组织理论、技术执行理论、协同治理理论等有助于加深对数字政府建设的理解和解释。基于行为科学和循证决策视角的研究,可为加快数字政府建设提供更加科学可行的政策建议。     

Uber in Queensland: From policy fortress to policy change

Emerging technologies are challenging the regulatory systems and industry policy settings that were settled during the microeconomic reforms of the 1980s and 1990s. In 1994, in the absence of credible competition in the taxi industry, Queensland legislation constructed a protective ‘policy fortress’ that benefited taxi licence holders in return for specific service standards. This entrenched a policy–industry nexus upheld by all political parties for two decades. But in 2014–2016, using disruptive digital platforms, Uber and similar organisations directly challenged the policy regime by rapidly expanding their unlicensed operations for personalised passenger bookings. Queensland policy-makers were eventually shocked into establishing a major review, leading to the termination of the protective regime. Drawing on interviews and policy documents, we identify the contextual and ideational factors that facilitated the unlocking of policy change. As consumers became more ‘tech-savvy’, the policy ideas championed by powerful new agents of change came to highlight consumer convenience, flexibility, and the ‘sharing economy’. Such narratives reframed the economic disruptions flowing from new technologies as opportunities to lower service costs.     

Conclusion: Four Recommendations to Improve Digital Electoral Oversight in the UK

To conclude this special section, this article looks at the possible avenues for regulatory reform in the field of digital campaigning. Diagnosing the need for a multi-layered approach, we argue that action is needed from government, regulators, companies, and civil society. We take each actor in turn and consider the kind of change needed, the prospects for reform, and outline four recommendations for change.     

A formal model for event reconstruction in digital forensic investigation

Event reconstruction is an important phase in digital forensic investigation, which determines what happened during the incident. The digital investigator uses the findings of this phase to prepare reports for the court. Since the results must be reproducible and verifiable, it is necessary that the event reconstruction methods be rigorous and strict. In order to fulfill the legal requirements, this study proposes an event reconstruction framework which is based on the formal mathematical methods. In particular, it uses the temporal logic model checking that is an automatic verification technique. The idea is that the system under investigation is modeled as a transition system. Then the digital forensic property is specified using the modal μ-calculus. Finally, a model checking algorithm verifies whether the transition system meets the property. In order to demonstrate the proposed formal event reconstruction framework, an abstract model of the FAT file system is presented and some digital forensic properties are formulated. A big problem in model checking is the so-called state space explosion. This study addresses this problem and suggests some solutions to it. Finally, the proposed framework is applied to a case study to demonstrate how some hypotheses can be proved or refuted.     

Examination of heterogeneous crossing sequences between toner and rollerball pen strokes by digital microscopy and 3-D laser profilometry

The determination of line crossing sequences between rollerball pens and laser printers presents difficulties that may not be overcome using traditional techniques. This research aimed to study the potential of digital microscopy and 3-D laser profilometry to determine line crossing sequences between a toner and an aqueous ink line. Different paper types, rollerball pens, and writing pressure were tested. Correct opinions of the sequence were given for all case scenarios, using both techniques. When the toner was printed before the ink, a light reflection was observed in all crossing specimens, while this was never observed in the other sequence types. The 3-D laser profilometry, more time-consuming, presented the main advantage of providing quantitative results. The findings confirm the potential of the 3-D laser profilometry and demonstrate the efficiency of digital microscopy as a new technique for determining the sequence of line crossings involving rollerball pen ink and toner.

Introduction: Regulation and Oversight of Digital Campaigning—Problems and Solutions

The regulation of digital technology is gaining increased attention within policy making circles. With growing recognition of the power held by digital media companies and the need to enforce democratic values online, policy makers are reviewing opportunities for oversight. Introducing a special section looking at the regulation of digital election campaigning, this article reviews the case for regulatory reform, the proposed type of regulatory change, and the practice of regulatory innovation. Noting the pace of digital change, it argues that there is a need to think more extensively about the design of any regulatory response in order to prevent systems of oversight becoming obsolete.     

Digital Inclusion for Persons with Disabilities in China Under COVID-19: How Far Has China Come?

This article reviews social regulatory and redistributive policies in China that aim at fostering digital inclusion of persons with disabilities. We examine the emerging Chinese policies and how China has responded to the impacts of the coronavirus disease (COVID-19) on digital inclusion in terms of redistribution, market regulation, involvement of persons with disabilities and disabled people’s organizations (DPOs), and awareness-raising campaigns. The policy review demonstrates that the Chinese policy framework contains a few redistributive initiatives, for example, cash transfer programs, and free distribution of information and communications technology (ICT). These have the potential to increase the uptake of ICT among persons with disabilities. The Chinese policy framework also includes provisions to ensure consultation with individual persons with disabilities and DPOs in the deliberation and implementation of ICT accessibility policies. While China has initiated awareness-raising campaigns among market actors about the importance of digital inclusion, so far, the Chinese government has adopted little legal regulation of the market to foster accessibility to ICT. The article thus argues that some of the limitations may be due to the way state–market relations have developed since the economy opened up in 1978. Apart from the growing benefits of several cash transfer programs, we have not seen major changes or adjustments to the current policy framework during the efforts to mitigate the impact of COVID-19 on digital inclusion.     

The diverse domains of quantified selves: self-tracking modes and dataveillance

The concept of self-tracking has recently begun to emerge in discussions of ways in which people can record specific features of their lives, often using digital technologies, to monitor, evaluate and optimize themselves. There is evidence that the personal data that are generated by the digital surveillance of individuals (dataveillance) are now used by a range of actors and agencies in diverse contexts. This paper examines the ‘function creep’ of self-tracking by outlining five modes that have emerged: private, communal, pushed, imposed and exploited. The analysis draws upon theoretical perspectives on concepts of selfhood, citizenship, dataveillance and the global digital data economy in discussing the wider socio-cultural implications of the emergence and development of these modes of self-tracking.
