Research on the Impact of Equity Pledge on Company Value

This article aims to provide a literature review on the impact of equity pledges on corporate value,and to explore in depth the application of equity pledges as a financial tool in corporate governance and capital operation,as well as its multidimensional impact on corporate value.By reviewing and analyzing relevant literature both domestically and internationally,this article first defines the basic concept of equity pledges and then elaborates on the impact mechanism of equity pledges on company value from both positive and negative perspectives.In terms of positive impact,this article explores how equity pledges can promote corporate financing,optimize capital structure,and enhance the control of major shareholders over the company.In terms of negative impacts,the possible control risk,market risk,and potential damage to the interests of small and medium-sized shareholders brought about by equity pledges were analyzed.Furthermore,this article also discusses the differences in the impact of equity pledges on company value in different scenarios and proposes corresponding policy recommendations and research prospects.

Evolution and Governance of the Structure of Marine Economic Networks in China’s Coastal Areas: Based on Sea-related A-share Listed Companies

Data on discrete,isolated attributes of the marine economy are often used in traditional marine economic research.However,as the focus of urban research shifts from internal static attributes to external dynamic linkages,the importance of marine economic net-work research is beginning to emerge.The construction of the marine economic network in China’s coastal areas is necessary to change the flow of land and sea resources and optimize regional marine economic development.Employing data from headquarters and branches of sea-related A-share listed enterprises to construct the marine economic network in China,we use social network analysis(SNA)to discuss the characteristics of its evolution as of 2010,2015,and 2020 and its governance.The following results were obtained.1)In terms of topological characteristics,the scale of the marine economic network in China’s coastal areas has accelerated and expan-ded,and the connections have become increasingly close;thus,this development has complex network characteristics.2)In terms of spatial structure,the intensity of the connection fluctuates and does not form stable development support;the group structure gradually becomes clear,but the overall pattern is fragmented;there are spatial differences in marine economic agglomeration radiation;the radi-ation effect of the eastern marine economic circle is obvious;and the polarization effect of northern and southern marine economic circles is significant.On this basis,we construct a framework for the governance of a marine economic network with the market,the government,and industry as the three governing bodies.By clarifying the driving factors and building objectives of marine economic network construction,this study aims to foster the high-quality development of China’s marine economy.

An Analysis on Cultural Values of Companies from China and the United States——Based on Hofstede's Cultural Dimension Theory

Nowadays, commercial competition is becoming fiercer and fiercer, and with the globalization proceeding, when a company tries to expand, promote and develop, it needs to adapt itself to the open business society while not losing its own culture.

Prognostic Value of Semi-Quantitative 18F-FDG PET/CT Parameters in Hodgkin’s Lymphoma

Objective:To assess the prognostic value of maximum standardized uptake value(SUVmax),metabolic tumor volume(MTV),and total lesion glycolysis(TLG)determined by 18F-fluorodeoxyglucose positron emission tomography-computed tomography(18F-FDG PET/CT)imaging in Hodgkin’s lymphoma patients.Methods:A total of 148 Hodgkin’s lymphoma patients diagnosed with lymph node biopsy from October 2014 to October 2015 were retrospectively analyzed followed by categorizing into good(125 cases)and poor(23 cases)prognosis groups.The chi-squared test was used to analyze the clinicopathological characteristics of Hodgkin’s lymphoma patients with the semi-quantitative 18F-FDG PET/CT parameters;the Spearman method was used to analyze the correlation between the semi-quantitative parameters and clinicopathological features of Hodgkin’s lymphoma;receiver operating characteristic curve was used to analyze the predictive value of the semi-quantitative parameters for poor prognosis of Hodgkin’s lymphoma patients.Results:Mean SUVmax,MTV,and TLG of the 148 cases of Hodgkin’s lymphoma were 7.26±2.38,12.46±3.14 cm3,and 76.83±18.56 g,respectively.Significant variations in the Ann Arbor stage and clinical classification were observed with different levels of semi-quantitative parameters(P<0.05).The semi-quantitative parameters were not correlated with age and gender(P>0.05)but positively correlated with Ann Arbor stage and clinical classification(P<0.05).These parameters in the poor prognosis group were higher than those in the good prognosis group(P<0.05).The area under the curve(AUC)of SUVmax,MTV,and TLG in predicting the poor prognosis group was 0.881,0.875,and 0.838,with cut-off values of 7.264,12.898 cm3,and 74.580g,as well as specificity of 88.8%,84.0%,and 78.4%,and sensitivity of 87.0%,87.0%,and 78.3%,respectively;the AUC of the combined prediction was 0.986,with a specificity of 97.6%and sensitivity of 86.3%.Conclusion:The semi-quantitative 18F-FDG PET/CT parameters provide valuable insights for Hodgkin’s lymphoma prognosis assessment.

The Value of Saudi Arabia Industrial Firms Between the Modigliani-Miller＇s and Gordon＇s Models： An Empirical Study on Cement Companies in Saudi Arabia

The most important target of the financial management is to develop the values of the foundation and develop the wealth of shareholders （wealth of the owners）, which is the primary target of the qualified and successful financial management. This target, developing the value of the foundation, depends on the total profit that could be achieved by the company and counting the profit per share, but undoubtedly, the financial management should consider the other targets such as social responsibility and exchange between risk and revenue and others. This research, with its both theoretical and practical aspects, aims at illuminating the value of some foundations in Saudi Arabia, which are already registered in the stock market, by comparing the value of each foundation using two models namely the model of Modigliani-Miller （M＆M） and the model of Gordon. In spite of the difficulties found in the usage of both models, especially Gordon＇s model, we will use both of them to explain the aspects of imperfection in each model. This research will depend on a sample of Sandi industrial companies by getting financial data of these companies over a past decade and the usage of these data, in other words, to measure the value of Saudi companies against the market.

Company Value and Employee Satisfaction： Theoretical Analysis and Empirical Findings

Employee satisfaction and its potential impact on business and company success have been in the focus of organizational and managerial practise and research ever since. This paper outlines the theoretical framework of this particular cause-effect proposition, and further examines if there is empirical evidence to substantiate the underlying research hypothesis, saying that increasing degrees of employee satisfaction have a positive impact on the company value. The company value can be measured by the equity value of a firm. With the primary data analysis, the authors compared 11 companies which took part in the Great Place to Work （GPTW） Contest in 2007 and 2009 （only in 2009） regarding their equity values and GPTW scores. The figures of these companies were provided to the authors in an anonymous form. The authors had no influence on the number of companies the GPTW Institute provided to them. The GPTW Institute tried to find companies which attend both contests and also show their financial data in the ＂Elektronischen Bundesanzeiger＂. This paper aims to foster these results with some additional primary statistical analyses for hypothesis testing. For this investigation, the authors conducted various types of statistical procedures which seem to confirm the underlying proposition. With different types of correlation analysis, the relationship between equity value and GPTW score was elaborated. By regarding the absolute average Earnings Before Interest and Tax （EBIT） and equity value of the eleven out of the 100 best companies, some differences can be pointed out by setting them in comparison to 30 randomly selected companies from Germany.

2022年四川芦山M_(S)6.1地震前应力状态研究

为研究2022年6月1日四川芦山M_(S)6.1地震的孕育和发生过程,采用CAP方法反演了2013年芦山M_(S)7.0主震及M_(S)≥5.0余震的震源机制解,并基于应力张量方差与b值时空分布特征,探讨了芦山M_(S)6.1地震的力学机制和震源区的应力状态。结果表明:2022年芦山M_(S)6.1地震震源机制表现出与2013年芦山M_(S)7.0主震和5级余震相似的逆冲型破裂特征,压应力轴方位与龙门山断裂带南段区域应力场一致。2013年芦山M_(S)7.0地震后震中及附近的应力张量方差和b值长期处于低值状态,2022年芦山M_(S)6.1地震前震中及附近出现了应力张量方差和b值的低值异常,表明芦山余震区处于较高的应力水平。分析认为:巴颜喀拉块体持续东向运动受到华南块体的阻挡,震中所在区域长期受挤压逆冲作用,从而使芦山余震区长期处于应力积累的状态,芦山M_(S)6.1地震也是在这种动力学背景下发生的。

梅毒螺旋体抗体最佳S/CO截断值在梅毒筛查中的应用价值

目的 以梅毒螺旋体凝集试验(TPPA)作为确认试验,确立酶联免疫吸附试验(ELISA)法S/CO值与梅毒阳性最佳截断值,减少不必要的TPPA确认重复。方法 选取2022年10月至2023年10月在医院进行梅毒螺旋体(TP)抗体检测的血清标本22 500例,以ELISA法为梅毒初次筛查试验,采用TPPA和甲苯胺红不加热血清试验(TRUST)对所有反应结果进行复核和确认。分析376例有反应性标本中的S/CO值与TPPA的关系,使用受试者操作特征曲线(ROC)确定ELISA法S/CO值与TPPA阳性最佳截断值。根据S/CO最佳截断值,比较梅毒不同反式筛查策略需要TPPA确认的标本数量。结果 当S/CO≥6.6时,TPPA与ELISA结果一致,特异性和阳性预测值均为100.00%,S/CO=6.6时为最佳截断值;使用欧洲疾病预防与控制中心(ECDC)策略时,376例筛查反应性样本(100.00%,376/376)需TPPA确认;使用美国疾病控制与预防中心(CDC)策略时,TPPA还需确认217例(57.71%,217/376);本研究只有122例(32.45%,122/376)需进行TPPA确认。结论 采用ELISA法梅毒反式筛查策略不受TRUST结果影响,当S/CO≥6.6时不需要进行TPPA确认,与ECDC和CDC反式策略相比,本研究有67.55%的筛查反应样本不必进行TPPA确认,经济且节约时间和人力。

Measuring Recreational Value of World Heritage Sites Based on Contingent Valuation Method:A Case Study of Jiuzhaigou

World heritage possesses various kinds of use value and non-use value. Measuring the recreational value of world heritage sites is a key issue in the heritage tourism. This paper employs Contingent Valuation Method (CVM), which is an evaluation instrument on the basis of tourists′ attitude and preference, to measure the recreational value of Jiuzhaigou, one of the World Natural Heritage sites in China, and analyzes the biases in the survey. The results show that: 1) In 2009, Jiuzhaigou′s recreational value was 3.46×108 yuan (RMB), and the per capita Willingness to Pay (WTP) was 137.31 yuan by CVM. Compared with the results of other methods, this result is significantly low. 2) Among the factors that influence Jiuzhaigou tourists′ WTP, psychological perception factors have the greatest effect while demographic and socio-economic characteristics have a small effect on WTP. 3) The virtuality in CVM creates biases both from CVM itself and in the procedures that CVM was implemented. The former includes hypothetical bias, information bias, protest response bias, and strategic bias; and the latter includes the questionnaire design, population and sample definition, sampling and data processing. The paper analyses those biases and illustrates their potential in-fluences on the accuracy of CVM measurement. 4) Although there are various defects in CVM measurement, it is still an effective valuation method.
