基于通道经济下的广西中心城市经济走廊构建反思

近年来广西建成的西南出海大通道,使大西南腹地和北部湾港口通过铁路、公路和航空网络形成了一个体系,但其体系功能并未充分发挥;充分利用广西独特的区位优势,资源优势及政策优势,加快广西中心城市经济走廊和通道经济建设,加强与东、西部地区的经济合作,实现"西江经济走廊"和粤桂一体化,全面融入殊三角,是广西构建中心城市经济走廊和通道经济建设和实现以"富裕广西、文化广西、生态广西、平安广西"为目标的"四个广西"和谐社会的必然选择.     

How do economic policy uncertainty and geopolitical risk drive Bitcoin volatility?

We investigate how economic policy uncertainty (EPU) and geopolitical risks (GPR) impact Bitcoin volatility with respect to factors related to type and nationality of uncertainty, investigated period, relationship horizon and extreme conditions. Applying ARDL model and quantile regression for monthly data from August 2010 to September 2021, we reveal that June 2014 corresponds to a key date that marks a reversal in the investigated relationship. Furthermore, we show that the relationship between uncertainty and bitcoin volatility changes according to different factors. US uncertainty has short run effects on Bitcoin volatility, while China’s uncertainty has rather long run effects. Moreover, Bitcoin volatility responds in the same manner to US EPU and GPR, while, it responds differently to China's EPU and GPR. In extreme quantiles, we find that Bitcoin hedges against US EPU and GPR. Further, Bitcoin hedges against either individual or joint effects of US uncertainty, but not both.

Accounting practices and professional power dynamics during a crisis

This paper examines how changes in accounting practices during a crisis can affect organisational dynamics between hospital managers and clinicians. Our theoretical framework applies a multi-dimensional concept of power (Hardy, 1996) – which distinguishes power over resources, processes and meaning – to a longitudinal case study of a public university hospital during a budgetary crisis. Based on interviews with managers and clinicians, three successive time intervals with distinct power constellations are identified. Initially, we identify a pre-crisis phase where management formally controls resources, which seems to have limited effects on clinician dominance because managers lack ‘processual power’ and ‘power of meaning’. Next, an implantation phase emerges whereby the introduction of mandated budget cuts triggers shifts in the distribution of power, such that managers acquire power by securing the collaboration of clinicians – a phenomenon which has tangible benefits in terms of enabling budget compliance and increased service provision. Finally, the third phase may be conceptualized as a fiscal pressure regimen whereby, when budgetary pressures intensify further, management's newly gained ‘power of meaning’ is eroded because management are now seen to pursue unrealistic demands. Drawing on research insights gleaned during each phase, our analysis contributes to extant literature in at least three ways. First, we present novel findings regarding the impact of crises-related applications of accounting practices on intra-organisational power constellations. Second, our work highlights how accounting practices help shape the understanding of crisis, which, in turn, impacts the distribution of organizational power and influences intra-organizational patterns of collaboration. Third, we find that awareness of the meaning power of accounting practices can help shape strategic action in crisis situations.
