A Study on Business Succession in Small and Medium-Sized Chinese Enterprises

The survival and development of SMEs (small and medium enterprises) is an important issue for the Chinese economy. In particular, business succession in SMEs is a persistent issue. Business succession involves selection of a successor, asset inheritance, transfer of management rights, accumulation of business connections and technology succession, and soforth. This all requires smooth execution of a business succession plan. However, many SMEs do not have a business succession plan, nor are they preparing one. Our task is to explore the reasons these preparations are not being made. Here, the purpose of our research is to get a picture of the status of preparations for business succession in SMEs in China, and the actual circumstances of succession, based on the results of a fact-finding survey of Chinese SMEs, and at the same time bring to the surface the primary factors which influence preparations and plans. The results of the analysis shed light on the status of business succession preparations, successor’s awareness of issues, decision making, and so on. This survey highlights the awareness of business succession among business managers.

Commercial Banks Responses toward Small and Medium Enterprises Survival in the Context of the COVID-19 in Africa

The African government has implemented measures to sustain an investable economic downturn as it navigates the fiscal effect of the viral spread of coronavirus disease 2019(COVID-19).Consequently,commercial banks in Africa have come hand in hand toward support of SMEs activities by increasing their borrowing power and reducing interest rates.Despite all these measures the general performance of small and medium enterprises(SMEs)across Africa as pertains to revenues and profits has gone down.This paper provides a theoretical analysis of the measures undertaken by commercial banks to ensure proper running and continuity of activities in the SMEs sector in Africa.The research is founded on the theories of innovation diffusion and resource-based theory.This study will use a mixed research design,which will include descriptive and explanatory research.The proposed target population will be Africa’s thriving commercial banks.The primary and secondary data will be used from commercial bank reports and the central bureau of statistics reports across Africa.The data will be analyzed using a multiple linear regression model.The finding indicated that commercial banks in Africa have brought in solutions and measures to adapt to the crisis being implicated on the SMEs by the COVID-19 pandemic.Based on the findings of the desktop reviews,the study concludes that commercial banks have a significant influence on SMEs during this period of COVID-19,and with the assistance of the government,they have implemented more policies to support the activities of SMEs.

Deep Learning Enabled Financial Crisis Prediction Model for Small-Medium Sized Industries

Recently,data science techniques utilize artificial intelligence(AI)techniques who start and run small and medium-sized enterprises(SMEs)to take an influence and grow their businesses.For SMEs,owing to the inexistence of consistent data and other features,evaluating credit risks is difficult and costly.On the other hand,it becomes necessary to design efficient models for predicting business failures orfinancial crises of SMEs.Various data classification approaches forfinancial crisis prediction(FCP)have been presented for predicting thefinancial status of the organization by the use of past data.A major process involved in the design of FCP is the choice of required features for enhanced classifier out-comes.With this motivation,this paper focuses on the design of an optimal deep learning-basedfinancial crisis prediction(ODL-FCP)model for SMEs.The proposed ODL-FCP technique incorporates two phases:Archimedes optimization algorithm based feature selection(AOA-FS)algorithm and optimal deep convo-lution neural network with long short term memory(CNN-LSTM)based data classification.The ODL-FCP technique involves a sailfish optimization(SFO)algorithm for the hyperparameter optimization of the CNN-LSTM method.The performance validation of the ODL-FCP technique takes place using a benchmarkfinancial dataset and the outcomes are inspected in terms of various metrics.The experimental results highlighted that the proposed ODL-FCP technique has out-performed the other techniques.

Analysis of the Financing Mode of Small and Medium-Sized Enterprises Under the DC/EP Platform Based on a Comparison with the Traditional Bank Financing Mode

As a legal currency with the credit endorsement of the Chinese government,DC/EP has many advantages and special characteristics.Based on the application of DC/EP in the financing of small-and medium-sized enterprises(SMEs),this paper studies the optimal financing decisions of SMEs under both the traditional financing mode and the DC/EP financing mode.Considering the construction and use costs of DC/EP and the role of DC/EP credit traceability in improving mortgage rates,this paper explores the feasible range for SMEs to select DC/EP financing.It is found that mortgage rates affect the returns of SMEs when they take on loans;under different credit strategies,the pledge rate set by the bank will affect the financing willingness of SMEs.The participants had different optimal mortgage rates to optimize the returns of borrowers and banks.High-quality SMEs are more willing to use the DC/EP platform for financing.With the increase in default costs,banks will be more inclined to use DC/EP,while enterprises will be inclined to utilize the traditional financing mode.Through the comparative analysis of the two financing modes,the default cost range that neither banks nor borrowers are willing to use DC/EP is found.This study provides theoretical support and management inspiration for scientific decision-making to solve the financing problems of SMEs by using DC/EP.

我国民营银行的发展现状、问题与对策建议

进入新时代以来,基于解决我国金融业发展不平衡不充分问题与优化金融市场结构体系的现实需要,国家出台了一系列政策支持民营银行的发展,民营银行由试点阶段进入到常态化经营阶段,资产负债规模和盈利能力大幅提升,逐渐成为服务中小企业的主力军。然而,由于战略定位不清晰、公司治理机制待完善、资本金支撑不足、抗风险能力较弱等问题,目前民营银行正面临严峻的挑战。因此,在未来的发展中,民营银行应坚定差异化经营,注重小微、民营、普惠等领域;完善公司治理机制,拓展资本金来源渠道;加强人才队伍建设,提高金融服务质量;借助金融科技,加快数字化转型,提升风险识别、防控和化解能力。同时,政府部门要强化政策引导,完善监管措施,助力民营银行更好地服务于实体经济。

征信服务平台奖惩机制下小微企业融资三方演化博弈及仿真分析

当前,我国小微企业融资主要以抵押贷款为主。在信用经济的背景下,如何发挥小微企业信用价值,进而以“信用”换贷款是解决小微企业融资难的关键。通过构建“小微企业—商业银行—征信服务平台”的三方演化博弈模型,探究征信服务平台能否改变小微企业融资形势,从而为激发民营经济更多活力提供政策支持。研究结果表明:征信服务平台通过建立合理的奖惩机制,满足对小微企业的奖惩之和大于贷款本金的条件,才能保证演化稳定市场环境下的小微企业获得高效融资。基于此,利用Matlab2022b进行仿真分析,提出相应的政策建议,具体包括:一是建设全国统一的征信服务平台;二是建立守信联合激励和失信联合惩戒长效机制;三是推出多种类、有特色的小额信用贷款产品。

信息环境现代化与“小银行优势”

通过考察信息环境现代化对“小银行优势”的影响,并从银企交往和银企距离这两项“小银行优势”机制机理中的关键环节及影响因素入手检视其影响机制。结果表明,“小银行优势”随着信息环境的现代化程度的提升而减弱。信息环境的现代化通过丰富企业信息内容和硬化企业“软信息”,改变了中小企业信息的“软硬”结构,拓展了非交往性企业信息获取方式,从而削弱了银企交往作为企业“软信息”获取方式的重要性,也削弱了空间距离造成的各种隔阂在其中的阻碍性,进而使亲近用户、善从交往以获取“软信息”的中小银行渐失其“小银行优势”的产生基础,反之缓解了大银行的比较劣势。这意味着随着信息环境的现代化发展,大小银行在缓解中小企业融资约束上的差异将被削弱,大银行也将拥有基于其自身特点缓解中小企业融资约束的施展空间。上述结论丰富了“小银行优势”的信息经济学内涵,也为现代信息技术条件下有效发挥不同银行的作用提供了政策启示。

Small mammal community composition impacts bank vole (Clethrionomys glareolus) population dynamics and associated seroprevalence of Puumala orthohantavirus

Rodents are important reservoirs for zoonotic pathogens that cause diseases in humans.Biodiversity is hypoth-esized to be closely related to pathogen prevalence through multiple direct and indirect pathways.For example,the presence of non-host species can reduce contact rates of the main reservoir host and thus reduce the risk of transmission(“dilution effect”).In addition,an overlap in ecological niches between two species could lead to increased interspecific competition,potentially limiting host densities and reducing density-dependent pathogen transmission processes.In this study,we investigated the relative impact of population-level regulation of direct and indirect drivers of the prevalence of Puumala orthohantavirus(PUUV)in bank voles(Clethrionomys glareolus)during years with high abundance.We compiled data on small mammal community composition from four regions in Germany between 2010 and 2013.Structural equation modeling revealed a strong seasonality in PUUV control mechanisms in bank voles.The abundance of shrews tended to have a negative relationship with host abundance,and host abundance positively influenced PUUV seroprevalence,while at the same time increasing the abundance of competing non-hosts like the wood mouse(Apodemus sylvaticus)and the yellow-neckedfield mouse(Apodemusflavicollis)were associated with reduced PUUV seroprevalence in the host.These results indicate that for PUUV in bank voles,dilution is associated with increased interspecific competition.Anthropogenic pressures leading to the decline of Apodemus spp.in a specific habitat could lead to the amplification of mechanisms promoting PUUV transmission within the host populations.
