The results found that economic policy uncertainty has a fast transmission to the risk of the banking system, it is difficult for banks to adjust their credit and leverage structure in a short period of time. As a result, the risk of banks increases rapidly and the value of banks becomes unstable. The banking system is much sensitive to economic policy uncertainty and quickly adjust its own operating structure in the next few periods to reduce its own risk-taking. Different bank responds to economic policy uncertainty with different ranges. However, the response direction is generally the same. That means economic policy uncertainty is systematic. In short-term, banks under the impact of economic policy uncertainty are mainly manifested as increase of bankruptcy risk taking, passive risk taking and market value fluctuation, while reduction of proactive risk taking. From the sample in this paper, it is found that banks with different property rights still have similar risk response situations.","PeriodicalId":223037,"journal":{"name":"Proceedings of the 2020 4th International Conference on Software and e-Business","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130712159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The movement of the stock market is even more difficult to predict due to its high instability. Faced with a large amount of stock market information, investors usually hope to use their known historical information to predict the future market ups and downs in some way, so as to apply them to investment and obtain excess returns. Improving the accuracy and income of stock selection is the main purpose of quantitative investment. The historical data of Shanghai stock 50 index and component stocks from 2012 to 2019 were used to show the daily rise and fall. Then, a quantitative stock selection strategy with random forest and support vector machine as the core of stock selection was constructed. The strategy can continuously obtain positive returns in the stock market. Several indicators were used as the index to evaluate the model, mainly including annualized return, information ratio, maximum drawdown, sharp ratio, etc. Combining the important technical indicators of these two models, we tried to find the most suitable choice for people and help investors maximize their interests. The return of support vector machine rises steadily in the whole year, which shows the stock selection strategy based on SVM is more accurate than random forest method. This also can help avoid missed opportunities due to the weakness of people's thinking.","PeriodicalId":223037,"journal":{"name":"Proceedings of the 2020 4th International Conference on Software and e-Business","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132592128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides that, for a corporation to perform business beyond its boundaries, e-business has become the main driver, implemented by an organization, to achieve this goal efficiently and effectively with relatively low costs. The new technological framework has changed the way companies perform their businesses. Hence, e-business has become the most important of a new era of business forms. Unsurprisingly, e-business stumbles in several threats (risks) which could hinder its functionality. These can be divided into twofold as internal and external risks. The risk management gained high attention on recent years due to the change in the trades’ evolution and the reoccurrence of global events that interrupted the global economy i.e. the collapses of the credit market and the housing market in the USA in 2008. Therefore, Risk management is vital to the development of e-business. Hence, risk management is deemed a vital technique for Audit for e-business.","PeriodicalId":223037,"journal":{"name":"Proceedings of the 2020 4th International Conference on Software and e-Business","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133448195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper starts from the framework of commercial banks' \"three principles \", namely, security, liquidity and profitability, and analyzes the challenges and opportunities brought by the interest rate marketization reform to China's commercial banks. Then the paper analyzes the characteristics of the two kinds of interest rate marketization models in the world, namely \"gradual\" and \"radical\", and concludes that the \"gradual\" reform model represented by the United States and other countries is also adopted by China. Reform path. Therefore, taking the Wells Fargo Bank and the Savings and Loan Association of the United States as an example to learn from the success and failure experience of American commercial banks in the process of interest rate marketization is conducive to the development of China's commercial banks. Finally, in response to the challenge of interest rate marketization to China's commercial banks, this paper puts forward the following suggestions combined with international experience: From a security standpoint, the state should improve the benchmark interest rate system and deposit insurance system, and banks should enhance risk awareness and establish from the perspective of liquidity.","PeriodicalId":223037,"journal":{"name":"Proceedings of the 2020 4th International Conference on Software and e-Business","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115289841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For enterprises, M&A efficiency is an important indicator to measure the effect of M&A. A large number of studies have analyzed the impact of M&A activities on enterprise efficiency in the short and long term from the change of financial indicators after M&A. However, few studies have analyzed the impact of bargaining power on M&A efficiency. Through the establishment of two-tier stochastic frontier model, we explore the influence of bargaining power on M&A efficiency and further investigate the deviation degree of M&A efficiency caused by bargaining power of both parties based on the sample of China's A-share listed companies in 2015-2018. The study concludes that there is a significant positive correlation between the bargaining power of the enterprises and the efficiency of M&A. We further find that the market competition intensity has a moderating effect on the relationship between the bargaining power of enterprises and the efficiency of M&A.","PeriodicalId":223037,"journal":{"name":"Proceedings of the 2020 4th International Conference on Software and e-Business","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128444368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, applying data science to software engineering (e.g., mining software repositories) can be blindfold and meaningless, if lacking a suitable knowledge architecture (KA). By observing that software engineering practices are generally recorded through a set of factors (e.g., programmer capacity, different environmental conditions, etc.) involved in various software project aspects, we propose a factor-based hierarchical KA of software engineering to help maximize the value of software repositories and inspire future software data-driven studies. In particular, it is the organized factors and their relationships that help guide software engineering knowledge mining, while the mined knowledge will in turn be indexed/managed through the relevant factors and their interactions. This paper explains our idea about the factorial KA and concisely demonstrates a KA component, i.e. the early-version KA of software product engineering. Once fully scoped, this proposed KA will supplement the well-known SWEBOK in terms of both the factor-centric knowledge management and the coverage/implication of potential software engineering knowledge.","PeriodicalId":223037,"journal":{"name":"Proceedings of the 2020 4th International Conference on Software and e-Business","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124753334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we analyze an application case in which multiparty computation protocols are used to increase the security level of digital resources stored encrypted in cloud environments that are constantly exposed to network threats. The distribution of the cryptographic secrets with the use of multiparty computation modules provides analyzed Enterprise Content Management system with the increased resistance to attacks on key confidentiality. With the proposed approach there is no need to choose between hardware-based cryptographic modules that are secure but expensive and traditional software-based centralized cryptographic modules that are affordable but vulnerable. Due to mass scale of application of Enterprise Content Management, the deployment of the solutions built similarly to the presented prototype may become a factor that significantly minimizes the security risks and business costs. The presented architecture can be used as a solid starting point for building secure enterprise systems that generate negligible costs in relation to their counterparts based on hardware-based cryptographic modules.","PeriodicalId":223037,"journal":{"name":"Proceedings of the 2020 4th International Conference on Software and e-Business","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127768186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
