Mixed oligopoly,state-owned banks’shareholding reform and foreign capital penetration

This paper examines the impact of the policy on eliminating the ratio of foreign shareholding in banks in a mixed oligopoly model.Its analytic results show that state-owned banks should encourage privatisation along with an increasing proportion of the domestic share in multinational banks.Furthermore,we argue that the increase in domestic stockholding of multinational banks raises domestic private firms’profits but decreases their social welfare in the deposit market.The results of numerical simulation show that when the quantity of private banks is fixed,foreign banks tend to enlarge their stake and strengthen their controlling power.

State-Owned Capital Participation in Private Enterprises:A Perspective of Debt Financing

This study takes debt financing as the entry point and explores the impact of state-owned capital participation in private enterprises from the perspectives of“unarticulated rules”and“articulated rules”.The study finds that state-owned capital participation significantly reduces the debt financing costs of private enterprises and expands the scale of their debt financing.This conclusion remains valid after a series of endogeneity and robustness tests.Further analysis of the mechanism reveals that state-owned capital participation improves the debt financing of private enterprises through multiple channels:Enhancing their social reputation,mitigating the“statistical bias”they face,optimizing their information quality,and reducing the“shareholder-creditor”agency problems.This paper conceptualizes these benefits as the“complementary advantages of heterogeneous shareholders”.This not only constructs a theoretical framework for“reverse mixed-ownership reform”but also better narrates the Chinese story of“mixed-ownership reform”by adopting a more universally applicable theory of equity structure.Additionally,the paper supplements existing research on the macro-and meso-level relationship between the government and the market by exploring the government’s positive role at the micro-level.

Research on Mixed Ownership Reform of State-Owned Enterprises from the Perspective of Marxist Political Economy

Under China’s socialist system,state-owned enterprises are key forces driving the economic trajectory and providing strong momentum.These enterprises not only bear the crucial responsibility of advancing the process of national modernization but also serve as the core of the national economic lifeline through their irreplaceable status and function amidst changing times.In the new era,with the advent of the technological revolution and the wave of globalization,state-owned enterprises face unprecedented opportunities and challenges.As a significant aspect of state-owned enterprise reform,the mixed ownership reform is not only a transformation in the structure of enterprise ownership but also a reflection of China’s broader,comprehensive reform efforts.By deeply advancing this reform,it will help optimize the allocation of state-owned assets and significantly boost technological and management innovation within state-owned enterprises,ensuring their competitiveness in the intense market environment.Therefore,this paper will conduct an in-depth analysis of the mixed ownership reform of state-owned enterprises from the perspective of Marxist political economy.

Internal Control Management and Risk Prevention Measures of State-Owned Enterprises

As an important pillar of national economic development,state-owned enterprises,their operational efficiency,and risk management ability are directly related to the stability and security of the national economy.As an important part of enterprise management,internal control management plays an irreplaceable role.Especially in the current domestic and international economic situation is complex and changeable,market competition is increasingly fierce environment,to strengthen the internal control management of state-owned enterprises and risk prevention measures is particularly important.This paper starts with the importance of internal control management and risk prevention for state-owned enterprises,and analyzes the problems and strategies in the internal control management and risk prevention of state-owned enterprises,in order to build a more comprehensive and efficient risk management system for state-owned enterprises to adapt to the ever-changing market environment and realize sustainable development.

Does Property Rights Reform Improve the Efficiency of China's State-owned Banks?

China ＂s state-owned banks have undergone radical changes over the past two decades, including partial privatization and listing in both the Hong Kong Stock Exchange and the Shanghai Stock Exchange. This paper evaluates the effects of these changes by analyzing the efficiency of Chinese banks over the period 1998-2012 using two frontier techniques and comparative analysis. The findings suggest that the performance and technical efficiency of the Big Four banks improved considerably after property rights reform, but this improvement is not sufficient to keep the banks at the production frontier. Tobit regressions confirm that static ownership effects are negative but that the property rights reform has had significant and positive effects on the technical efficiency of state-owned commercial banks. GDP growth and the financial crisis have had positive effects on the efficiency of Chinese banks, which is more significant for joint stock commercial banks than state-owned commercial banks. The results indicate the value of ownership reforms of state-owned asset management companies and insurance companies and the establishment of a countercyclical capital buffer.

Time series prediction of reservoir bank landslide failure probability considering the spatial variability of soil properties

Historically,landslides have been the primary type of geological disaster worldwide.Generally,the stability of reservoir banks is primarily affected by rainfall and reservoir water level fluctuations.Moreover,the stability of reservoir banks changes with the long-term dynamics of external disastercausing factors.Thus,assessing the time-varying reliability of reservoir landslides remains a challenge.In this paper,a machine learning(ML)based approach is proposed to analyze the long-term reliability of reservoir bank landslides in spatially variable soils through time series prediction.This study systematically investigated the prediction performances of three ML algorithms,i.e.multilayer perceptron(MLP),convolutional neural network(CNN),and long short-term memory(LSTM).Additionally,the effects of the data quantity and data ratio on the predictive power of deep learning models are considered.The results show that all three ML models can accurately depict the changes in the time-varying failure probability of reservoir landslides.The CNN model outperforms both the MLP and LSTM models in predicting the failure probability.Furthermore,selecting the right data ratio can improve the prediction accuracy of the failure probability obtained by ML models.

Franchise Value Change Information of State-owned Commercial Bank and Securities Investment Risk

The investment strategy choice of state-owned commercial bank is related to its franchise value change information. This paper analyzes the franchise value change information of state-owned commercial bank. The franchise value change information shows that the franchise value of state-owned Commercial Bank is descending. Along with the descending of the franchise value, state-owned commercial bank strengthens its high risk investment motive when it chooses its investment strategy. State-owned commercial bank tends to run the high risk of investing securities because its investment variety is very sparse. Based on the theoretical principle of how to control securities investment risk, this paper proposes some countermeasures and suggestions that state-owned commercial bank strengthen the control of its securities investment risk in order to perfect its investment strategy.

Spatiotemporal characteristics of seed rain and soil seed bank of artificial Caragana korshinskii Kom. forest in the Tengger Desert, China

Vegetation restoration and reconstruction are effective approaches to desertification control and achieving social and economic sustainability in desert areas.However,the self-succession ability of native plants during the later periods of vegetation restoration remains unclear.Therefore,this study was conducted to bridge the knowledge gap by investigating the regeneration dynamics of artificial forest under natural conditions.The information of seed rain and soil seed bank was collected and quantified from an artificial Caragana korshinskii Kom.forest in the Tengger Desert,China.The germination tests were conducted in a laboratory setting.The analysis of species quantity and diversity in seed rain and soil seed bank was conducted to assess the impact of different durations of sand fixation(60,40,and 20 a)on the progress of vegetation restoration and ecological conditions in artificial C.korshinskii forest.The results showed that the top three dominant plant species in seed rain were Echinops gmelinii Turcz.,Eragrostis minor Host.,and Agropyron mongolicum Keng.,and the top three dominant plant species in soil seed bank were E.minor,Chloris virgata Sw.,and E.gmelinii.As restoration period increased,the density of seed rain and soil seed bank increased first and then decreased.While for species richness,as restoration period increased,it gradually increased in seed rain but decreased in soil seed bank.There was a positive correlation between seed rain density and soil seed bank density among all the three restoration periods.The species similarity between seed rain or soil seed bank and aboveground vegetation decreased with the extension of restoration period.The shape of the seeds,specifically those with external appendages such as spines and crown hair,clearly had an effect on their dispersal,then resulting in lower seed density in soil seed bank.In addition,precipitation was a crucial factor in promoting rapid germination,also resulting in lower seed density in soil seed bank.Our findings provide valuable insights for guiding future interventions during the later periods of artificial C.korshinskii forest,such as sowing and restoration efforts using unmanned aerial vehicles.

Research on Early Warning of Banking Crises from the Perspective of Credit Structures

The relationship between credit expansion and banking crises is complex and cannot be fully explained by total credit alone.A systematic analysis of the relationship between the amount and structure of total credit and banking crises is important for an objective prediction of the influence of potential financial risks.This paper,drawing on data from 15 selected countries,delves into the power of credit indicators in the early warning of banking crises from the perspectives of industrial structure,sector structure,and term structure of credit.Various machine learning methods were used,including Logistic Regression,Random Forest,Decision Tree,Support Vector Machine(SVM),Bagging,and Boosting models.The empirical findings indicate that credit expansion plays a crucial role in triggering banking crises.However,total credit is better suited for the early warning of short-term banking crises,whereas credit structure is more useful for the early warning of long-term banking crises.Moreover,in an early warning system,identifying key early warning indicators is more meaningful than merely increasing the number of indicators.Machine learning can somewhat enhance the early warning power,but it may not always be robust.Therefore,more attention should be paid to potential systemic banking crises resulting from an imbalance in credit structure while regulating the total credit threshold.

The Impact of the Monetary Policy During the COVID-19 in the Brazilian Banking Sector

The COVID-19 pandemic caused an outbreak on the global productive chains,transforming companies and society in general.Governments adopted anticyclical policies such as basic interest rates reduction as response.Brazil basic interest rate is denominated Selic.The application of these policies requires the protagonist of bank’s financial intermediation.This study aims to verify two events-under the perspective of the efficient markets’theory.The first is the communication of the first death by COVID-19-and the subsequent,Selic rate reduction to 2%p.a.-and its effects on bank’s shares prices.The hypotheses presented are:H1-The announcement of the first death by COVID-19 negatively impacts the banks’shares returns and H2-The announcement of the Selic interest rate-during the COVID-19-positively impacts the return of the banks’shares.We adopt event study methodology in a final sample of nine and 15 banks to Events 1 and 2 respectively.The results confirm H1 as well as the semi-strong informational efficiency market.H2 is not confirmed.Results confirm the non-effectiveness of the anticyclical policy of basic interest rate reduction.This contributes to the discussion about the impacts of COVID-19 and the efficacy of anticyclical policies.

ISMB:多核系统中利用Bank分区实现共享库隔离

动态随机存取存储器DRAM一直以来以其低功耗、高性价比和良好的扩展性等优点作为计算机内存的最佳选择。为了提高内存的访问速度,DRAM中的每个Bank都有一个行缓冲区,它可以有效地提升局部性良好的应用程序的性能。然而在多核系统中,DRAM被系统中的所有Core共享,因此对内存的并发访问会导致Bank行缓冲区冲突问题的产生,从而导致内存访问延迟的增大。共享库作为一种共享资源,使Bank行缓冲区冲突问题更加严重。虽然目前有一些基于DRAM Bank分区技术的解决方案可以有效缓解由进程访问私有内存导致的Bank行缓冲区冲突问题,但是这些解决方案无法解决访问共享库引起的Bank行缓冲区冲突问题。该文提出了一种在多核系统中利用Bank分区实现共享库隔离的方案(ISMB)。ISMB使运行在同一个Core上的进程只能访问属于该Core的共享库的副本,因此ISMB消除了共享库导致的Bank行缓冲区冲突问题。对比实验结果表明,ISMB能够有效地提升系统隔离性能,在使用ISMB的情况下,SPEC CPU2006基准测试程序的减速率最大可降低26.3%。
