从产品主导逻辑到服务主导逻辑：能力重构视角下企业的数字化转型研究

在数字化经济时代,越来越多的企业在数字化转型中将战略思维从产品主导逻辑升级为服务主导逻辑,以适应变化的外部环境。本文采用案例研究方法,基于能力重构视角深入分析3家企业数字化转型中的主导逻辑升级现象。结论显示：企业从产品主导逻辑向服务主导逻辑的升级可以解构为核心资源、价值创造以及创新模式的转变,能力重构在这一主导逻辑升级中产生了重要的作用机制,具体表现为适应能力重构、学习能力重构与创新能力重构。本文最终所形成的理论框架,填补了现有文献对于企业数字化转型中的主导逻辑升级现象关注不足所造成的理论缺口,并对实践中欲利用数字化实现主导逻辑升级的企业给出借鉴与参考。

‘This could be our reality in the next five to ten years’: a blogpost platform as an expectation generation device on the future of insurance markets

William James (1919) characterises hypotheses as either live or dead. A hypothesis is live when it is taken into account as a ‘real possibility’. We follow James’ suggestion to not attribute intrinsic properties to hypotheses, but rather investigate how they came into being and look at the effects they generate. Expectations of digital technologies are a topic of vivid debate in the insurance industry. Before these expectations can become ‘live’, they have, in the first place, to be generated by market devices. We investigate how the reinsurance blogpost platform Open Minds functions as an ‘expectation generation device’ on the future of insurance markets. Combining Beckert’s work on the role of fictional expectations with the pragmatist turn in sociology of markets, we propose to study ‘expectation generation devices’, provoking expectations on economic markets. In our empirical analysis, we demonstrate the explicit fictional character of the Open Minds contributions, and analyse how a contained space of openness is generated to provoke expectations. We demonstrate how Open Minds can become live through circulation to other expectation generation sites in the insurance industry and beyond. We conclude by reflecting on the importance of expectation generation devices as a particular type of market devices.     

Bulgarian pirates: At the world's end

The present article compares the strategies of the legitimation of piracy developed by Western authors such as Richard Stallman and Larry Lessig with those developed by everyday Bulgarian pirates. It attempts to escape from the usual debate between the entertainment industries and the supporters of free culture, and to open the field for new perspectives. In Bulgaria it is precisely “free” as in “free beer” that matters, since the prices of cultural products tend to be too high for the Bulgarian market. In many cases, there is no possible legal access to the cultural products desired. The digital library “Chitanka” illustrates how piracy as bottom-up initiative compensates for the lack of successful public policies oriented towards visually impaired people and Bulgarian emigrants abroad. Although mobility and de-territorialisation have made piracy possible, it is perceived as a deeply national cause. The article emphasises that a difference should be made between open non-commercial projects as “Chitanka” and commercial torrent trackers, which thrive in the grey economy and abuse the symbolic capital of free culture. Piracy should be analysed at the intersections of global economic shifts and their local repercussions, of transnational culture flows and local culture infrastructure. Only this kind of an approach is likely to help us trace the unstable border between the cases in which digital piracy is a problem of the grey economy, and those in which it offers original non-market solutions to deeper structural problems.
