To promote theoretical and empirical research on blockchain-enabled supply chain finance in China, this article provides an overview of relevant studies in China. Currently, research related to blockchain-enabled supply chain finance in China primarily focuses on three aspects: the underlying mechanisms of blockchain-enabled supply chain finance (including decentralization and consensus mechanisms, distributed storage, tamper resistance, and anti-denial features, as well as smart contracts), the positive effects of blockchain-enabled supply chain finance (including comprehensive effects, credit transmission, risk management) and the application scenarios of blockchain-enabled supply chain finance, and the impact mechanisms of blockchain on supply chain finance gaming behaviors (including the influence of blockchain on supply chain finance decision-making, risk assessment, and the supply chain financial system). Overall, research in China on the positive effects of blockchain-enabled supply chain finance (such as cost and benefit analysis, micro-level efficiency) is relatively limited. Additionally, studies on the factors affecting the adoption of blockchain in supply chain finance and the behavior of banks and small and medium sized enterprises (SMEs) in blockchain adoption within supply chain finance are relatively scarce. Given the backdrop of financial technology, further research is needed to deepen our understanding of various aspects related to blockchain-enabled supply chain finance in China.
为了促进中国区块链供应链金融的理论和实证研究,本文对中国相关研究进行了概述。目前,国内对区块链支持的供应链金融的研究主要集中在三个方面:区块链供应链金融的底层机制(包括去中心化和共识机制、分布式存储、防篡改和反拒绝特性以及智能合约)、区块链供应链金融的积极效应(包括综合效应、信用传导、风险管理)以及区块链供应链金融的应用场景;区块链对供应链金融博弈行为的影响机制(包括区块链对供应链金融决策、风险评估、供应链金融体系的影响)。总体而言,中国对区块链支持的供应链金融的积极影响(如成本效益分析、微观层面效率)的研究相对有限。此外,关于影响供应链金融采用区块链的因素以及银行和中小企业在供应链金融中采用区块链的行为的研究相对较少。在金融科技的背景下,需要进一步的研究来加深我们对中国区块链供应链金融的各个方面的理解。

This article takes 30 listed enterprises in the manufacturing industry as samples, uses the KMV model to measure the default distance, and tests the validity of the measurement results to investigate whether issuing green bonds has a potential impact on the credit risk of enterprises. The results show that the KMV model has a better ability to predict corporate credit risk; and enterprises that have issued green bonds generally have lower credit risk due to signaling effects and other effects. Finally, this article puts forward relevant recommendations such as policy support and database construction based on the research results. This article provides a basis for enterprises to broaden financing channels and strengthen credit risk management.
本文以30家制造业上市企业为样本,采用KMV模型对违约距离进行测度,并检验测度结果的有效性,探讨发行绿色债券是否对企业信用风险存在潜在影响。结果表明,KMV模型对企业信用风险具有较好的预测能力;而发行绿色债券的企业由于信号效应等效应,信用风险普遍较低。最后,本文根据研究结果提出了政策支持、数据库建设等相关建议。本文为企业拓宽融资渠道,加强信用风险管理提供了依据。

In the wake of the COVID-19 outbreak, China implemented emergency epidemic prevention and control measures, which played a positive role in economic and social development as well as the containment of the epidemic. Based on stock trading data from February 2020 to December 2022, this paper examines the impact of these measures on the stock returns of A-share listed companies. The findings of the study indicate that social distancing and health measures generally increase stock market returns, despite the varying magnitude of their effects. In addition, the analysis of two aspects, namely the listed sectors and the industry response analysis, further corroborates the main conclusion that social distancing policies have a more pronounced effect on the stock market. The study helps investors understand how the stock market responds to government announcements and enables policymakers to further explore the impact of policy responses during major public health events and their influence on economic and social welfare.
新冠肺炎疫情发生后,中国采取紧急疫情防控措施,为经济社会发展和疫情防控发挥了积极作用。本文基于2020年2月至2022年12月的股票交易数据,检验了这些措施对a股上市公司股票收益的影响。研究结果表明,社交距离和卫生措施通常会增加股市回报,尽管它们的影响程度各不相同。此外,通过对上市板块和行业反应分析两方面的分析,进一步印证了社会距离政策对股市影响更为明显的主要结论。该研究有助于投资者了解股市对政府公告的反应,并使政策制定者能够进一步探讨重大公共卫生事件期间政策反应的影响及其对经济和社会福利的影响。

This study assessed the risk management or preparedness measures in Liquefied Petroleum Gas (LPG) stations in Port Harcourt metropolis. The sample size of this study comprised of 79 licensed Liquefied Petroleum Gas Stations located within the metropolis obtained from the regulatory agency. The data were collected, administered analyzed using Kobocollect App, Spearman Rank Correlation and percentages. The findings reveal that 96.2% of gas stations were stand-alone while 3.8% are with petrol stations, the storage tanks are cylindrical and were placed above-ground. Majority (88.61%) of the staff have been trained in safety and firefighting with 65.82% possessing automated Gas detector, 21.52% having mechanical gas detector, 8.68% having both mechanical and automated gas detectors while 5.06% have no leak detection devices. Also, 88.61% of gas stations have emergency plans, 3.8% have no emergency plans while on how often drills were conducted; 50.63% of respondents indicated that drills were conducted once, 22.78% twice and 3.8% thrice a year. Finally, it was found that 86.7% of the vulnerability to LPG station risk is determined by the type of station. There is therefore the need for regular assessment and monitoring of facilities by the regulatory agency to mitigate potential disasters due to LPG stations for sustainable development in the metropolis.

Climate change has led to frequent occurrence of extreme weather events, which seriously affect human life and production in terms of frequency, intensity and duration. It has become one of the important risk factors faced by enterprises, and the construction industry occupies an important position in China's national economy, which is inevitably affected by extreme weather. Therefore, based on the panel data of Chinese A-share construction enterprises from 2010 to 2022, this article studies the impact of extreme climate on corporate financial performance. It is found that the extreme low temperature climate significantly improves the financial performance risk of the construction industry, while the extreme high temperature climate and extreme rainfall climate have no significant impact on the financial performance of the construction industry. This study expands the literature on the impact of extreme weather on the performance of listed companies, encourages enterprises to further recognize the importance of extreme climate, and provides suggestions for corporate managers on how to deal with extreme climate.
气候变化导致极端天气事件频繁发生,在频率、强度和持续时间上严重影响着人类的生活和生产。它已成为企业面临的重要风险因素之一,建筑业在中国国民经济中占有重要地位,不可避免地受到极端天气的影响。因此,本文基于2010 - 2022年中国a股建筑企业面板数据,研究极端气候对企业财务绩效的影响。研究发现,极端低温气候显著改善了建筑业财务绩效风险,而极端高温气候和极端降雨气候对建筑业财务绩效没有显著影响。本研究拓展了极端天气对上市公司绩效影响的文献,促使企业进一步认识到极端气候的重要性,并为企业管理者如何应对极端气候提供建议。

This paper evaluates the effect of income tax preferences for digital economy enterprises based on the data of digital economy enterprises in Beijing, Tianjin and Hebei regions from 2017-2021 (in line with the narrower caliber of the National Bureau of Statistics). The research results show that corporate income tax incentives have a significant impact on R&D investment of digital economy enterprises and provide a better incentive for digital economy enterprises to increase their R&D investment efforts. Tax incentives are heterogeneous in nature of property rights for digital economy enterprises, among which there is a greater promotion for private enterprises. Finally, this paper further expands the study on the factors influencing the innovative capability of enterprises and proposes policy recommendations on the relationship between tax preferences and innovation capability of enterprises based on the empirical results.
本文基于2017-2021年京津冀地区数字经济企业数据(符合国家统计局较窄口径),对数字经济企业所得税优惠的效果进行评估。研究结果表明,企业所得税优惠对数字经济企业的研发投入有显著影响,能够更好地激励数字经济企业加大研发投入力度。数字经济企业的税收优惠具有产权异质性,其中对民营企业的促进作用更大。最后,本文进一步拓展了对企业创新能力影响因素的研究,并根据实证结果提出了税收优惠与企业创新能力关系的政策建议。

This paper examines the impact of fiscal pressure on the degree of deviation from budgetary revenue based on provincial panel data from 2011 to 2020. The results show that fiscal pressure has a positive impact on the deviation of local government budget revenues, with the impact of fiscal pressure on the deviation of non-tax revenues significantly higher than that of tax revenues; the positive impact of fiscal pressure on the deviation of local government budget revenues is more obvious in regions with higher reliance on land finance; the proportion of tax revenues in fiscal revenues negatively moderates the impact of fiscal pressure on the deviation of local government budget revenues. The impact of fiscal pressure on the degree of deviation of local government budgetary revenue is negatively moderated by the share of tax revenue in fiscal revenue.
本文基于2011 - 2020年各省面板数据,考察了财政压力对预算收入偏离程度的影响。研究结果表明:财政压力对地方政府预算收入偏差具有正向影响,财政压力对非税收入偏差的影响显著高于税收收入偏差的影响;财政压力对地方政府预算收入偏差的正向影响在土地财政依存度较高的地区更为明显;税收收入占财政收入比重负向调节财政压力对地方政府预算收入偏差的影响。财政压力对地方财政预算收入偏差程度的影响被税收收入占财政收入的比重负向调节。

The COVID-19 pandemic made it more difficult for entrepreneurs to obtain capital finance from banks. As a result of disruptions caused by the COVID-19 pandemic, entrepreneurs found alternative means of obtaining capital finance in the form of crowdfunding. Crowdfunding has the potential to help entrepreneurs get access to finance. The prevalence of crowdfunding campaigns in Africa is relatively low compared to most developed economies around the world. The objective of the study was to determine the role of social networks on crowdfunding performance during the COVID-19 pandemic in Africa. A total of 859 crowdfunding projects in Africa were analysed in the study. The ordinary least squares (OLS) and probit models were estimated in the analysis. The duration, comments, and target amount variables were found to be negatively and significantly associated with crowdfunding success in Africa. Conversely, the presence of videos, updates and backer’s variables were positively and significantly associated with the success of crowdfunding campaigns. The study contributes to new knowledge by revealing the influence of the COVID-19 pandemic and the role of social networks on crowdfunding performance in Africa. Furthermore, the study makes a policy recommendation to African governments on the need to craft policy instruments that will foster the development of crowdfunding sources which will ultimately mitigate the problem of credit rationing by banks which curtail the growth of entrepreneurs.
2019冠状病毒病大流行使企业家更难从银行获得资本融资。由于COVID-19大流行造成的中断,企业家找到了以众筹形式获得资本融资的替代手段。众筹有可能帮助企业家获得融资。与世界上大多数发达经济体相比,非洲众筹活动的普及程度相对较低。该研究的目的是确定社交网络在非洲COVID-19大流行期间对众筹业绩的作用。该研究共分析了非洲859个众筹项目。在分析中估计了普通最小二乘(OLS)和probit模型。持续时间、评论和目标金额变量被发现与非洲众筹成功呈显著负相关。相反,视频、更新和支持者变量的存在与众筹活动的成功呈正相关。该研究通过揭示COVID-19大流行的影响以及社交网络对非洲众筹绩效的作用,有助于获得新知识。此外,该研究还向非洲各国政府提出了一项政策建议,即需要制定政策工具,促进众筹资源的发展,从而最终缓解银行信贷配给的问题,这一问题阻碍了企业家的增长。
