Exploring the dynamic spillover of cryptocurrency environmental attention across the commodities,green bonds,and environment-related stocks

We analyze the dynamic spillover impact of cryptocurrency environmental attention (ICEA) on three asset classes: commodities, green bonds (GBs), and environment-related stocks. Our wavelet-based analysis suggests that ICEA is sharply escalated after the first quarter of 2021. During this period of intense attention, only the soybean commodity and Solactive GB tend to move positively and negatively with ICEA, respectively. Accordingly, the clean energy, sustainability, and Environmental, Social, and Governance (ESG) stock indices are positively associated with ICEA during 2018–2019 at the medium frequency bands. In most periods and frequency domains, most commodities, GBs, and environment-related stocks are not strongly linked to ICEA. Moreover, Diebold and Yilmaz’s (2014) spillover estimations signify no strong spillover effect of ICEA on the asset classes considered in this study. These findings are further corroborated by the wavelet-based Granger causality analysis. Moreover, our quantile regression (QR) estimations suggest that most assets are adversely influenced by ICEA, depending on the market conditions. Our research conveys some novel and vital policy ramifications to both investors and policymakers.     

“全面禁伐”前后林业产业结构的演变分析——以大小兴安岭林区为例

以"全面禁伐"政策实施为节点,对大小兴安岭林区林业产业结构的演变过程进行分析。通过运用2009~2012年大小兴安岭林区相关数据,基于灰色发展决策模型以及灰色加权模型,对林区林业产业次级产业综合发展系数进行测算,明确林区林业产业结构演变趋势。研究结果表明:"全面禁伐"前木质资源生态接续产业发展就较为缓慢,而随着"全面禁伐"政策的实施,该区域木质资源生态接续产业发展将更加艰难。因此,提出加大森林生态资源的培育、增强非木质资源替代产业的发展、优化与调整木质资源接续产业等林业产业结构调整与优化的对策建议。     

黄金上市公司经营效率的动态评价

黄金上市公司的经营效率水平是衡量我国黄金产业综合竞争实力的最重要标准。文章采用Malmquist指数方法,依据我国黄金上市公司2007-2012年的面板财务数据,从动态角度对我国黄金产业的效率水平及演化趋势进行了分析与评价。研究表明：2007-2012年,我国黄金上市公司的平均全要素生产率呈现年均5％的衰退趋势;技术进步效率是制约我国黄金上市公司全要素生产率提高的主要因素;考察期内,综合技术效率、纯技术效率和规模效率均未发生明显的增减变动。

Enhancing the AIS curriculum: Integration of a research-led,problem-based learning task

Issues relating to student learning outcomes, retention and engagement, together with pressure to reinvigorate and differentiate higher education programs through integrating research-based material into the curriculum, are repeatedly in the spotlight. This paper reports on successful results from a case study of a student-centered, research-led, problem-based learning task that was incorporated into the curriculum of an Accounting Information Systems subject. Through engaging students with the learning experience, the curriculum changes addressed identified needs for improved communication, reflective appraisal as well as analytical and critical thinking skills in higher education graduates. The paper concludes with details of student perceptions of the task and learning outcomes, a review of academic performance, and reflection on the methodologies employed.     

Does transition to IFRS substantially affect key financial ratios in shareholder-oriented common law regimes? Evidence from the UK

This paper provides evidence of how a transition to IFRS affects key financial ratios and the pertinent financial statement items. Building on Lantto and Sahlström's (2009) evidence from creditor-oriented code law regimes, we examine the impact of IFRS transition on listed companies in the shareholder-oriented common law regime of the UK. The study contributes two insights: First – despite their similarities – conversion from the UK General Accepted Accounting Principles (GAAP) to IFRS leads to substantial differences in key financial ratios. These even surpass differences reported by companies in creditor-oriented code law regimes. We find that medians of profitability ratios increased substantially: Operating Income Margin (OPM) increased by 10.8%, Return on Equity (ROE) by 27.0%, and Return on Invested Capital (ROIC) by 14.4%. The Current Ratio (CR) and Price-to-Earnings (P/E) Ratio also exhibit significant but less drastic changes of 4.2% and − 2.9%, respectively. Second, differences in shareholder-oriented common law regimes have the same causes as in creditor-oriented code law regimes, i.e., an increase in Operating Income, Net Income, Current Liabilities and Invested Capital, as well as a decrease in Shareholder Equity.     

境外股东持股对我国商业银行经营绩效的影响研究

境外战略投资者的引入是否能够实质性地改善我国商业银行的公司治理从而提升经营绩效,这是我国银行业对外开放以来备受实务界、政策层和学术界广泛关注的重要课题。本文运用我国银行业33家上市或非上市商业银行在1998~2010年间的面板数据,实证研究境外股东持股如何影响我国商业银行的经营绩效。同时采用资产收益率和不良贷款率来度量经营绩效,并在控制了其他公司层面因素的影响后发现,境外股东的引入显著地改善我国商业银行的公司治理效力,提升经营绩效,表现为资产收益率的显著上升和不良贷款率的显著下降。根据实证研究结果,本文提出了有针对性的政策建议。

China׳s information security standardization: Analysis from the perspective of technical barriers to trade principles

There have been many attempts for ICT standardization in China. Among them, this paper deals with information security standards. Although information security is often mentioned regarding China?s ICT standardization, it has been rarely examined per se. While most studies on China?s ICT standardization focus on economic aspects (e.g. increased bargaining power) or the government?s role, this paper draws on legal aspects. We select WAPI and ZUC for case studies, and examine their legal aspects, particularly from the perspective of WTO?s TBT (technical barriers to trade) principles. We have found that China?s standardization strategy becomes international-bound and, in fact, the manner in which the Chinese government handles standardization projects has become refined, flexible, and communicative with foreign stakeholders. We see that the changes are responses to the trade concerns raised by foreign stakeholders in various TBT Committee meetings and bilateral meetings. In addition, the Chinese government appears to become market-oriented even in the field of information security where it previously maintained a rigid stance on the ground of national security. This paper points out that the changes are attributed to growing external pressure from foreign governments and firms as well as to internal efforts toward innovation based on indigenous technology.
