Because there are some uncertain factors in protection, circuit breaker misoperation, rejection and channel reasons, a kind of disaster assessment method that can realize uncertain information is of great significance. Although the traditional evaluation algorithm based on rough set can deal with uncertain information, it can only deal with discrete data effectively. In practice, there are continuous data and most of them are fuzzy, and the boundary between concepts is not very clear. Fuzzy set can overcome this disadvantage. This paper creatively proposes a method based on intuitionistic fuzzy rough set to evaluate power grid disasters timely and accurately. In the evaluation, attribute filtering and data cleaning are used to reduce the redundancy of disaster attributes; Through value filtering, the evaluation rules are extracted, the disaster level is determined through matching, and adjusted and updated with the development of the situation, so as to provide a scientific basis for emergency decision-making.","PeriodicalId":154348,"journal":{"name":"2021 5th Annual International Conference on Data Science and Business Analytics (ICDSBA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114523068","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}

University laboratory as a key place of university education, because of its more and more high functional requirements for the laboratory construction requirements to standardize, intelligence, information, open, sharing the direction forward. Because of the increase of experimental projects and experimental instruments, the management of laboratories has become cumbersome. The management of modern laboratories is not applicable to the traditional form of manual management. The management of laboratories is also increasingly information-based and intelligent. Based on the research and analysis of laboratory construction and management at home and abroad, this paper designs open intelligent laboratory management measures combined with big data technology, and uses the Internet of Things and big data technology to build a laboratory management system. Building a wireless sensor network for laboratory environmental information collection, the intelligent control and support management of the laboratory can be shown through the intelligent terminal equipment, including access control card, intelligent lighting regulation, temperature and humidity detection, feedback equipment information management and so on. The data mining and analysis of the laboratory is realized by collecting the digital information of the laboratory, which provides decision support for the intelligent management of the laboratory.","PeriodicalId":154348,"journal":{"name":"2021 5th Annual International Conference on Data Science and Business Analytics (ICDSBA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114866111","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}

Analysis on the Influence Mechanism of RMB Internationalization on China’s OFDI : Based on the “The Belt and Road Country Panel Data” Model 人民币国际化对中国对外直接投资的影响机制分析——基于“一带一路”国家面板数据模型

Using panel data model, this paper empirically studies the influence mechanism of RMB internationalization on China’s OFDI. The results show that the level of RMB internationalization has a positive effect on the stock of China’s OFDI to \"The Belt and Road\" countries. China’s import and export trade with host countries significantly contributed to the growth of OFDI. The economic development level of the host country has a significant positive effect on OFDI of Chinese enterprises, while the economic distance between China and the host country and the exchange rate fluctuation of the host country have a negative effect on OFDI. Therefore, this paper puts forward the following suggestions: China should continue to promote and deepen the \"The Belt and Road\" construction, promote the internationalization of RMB and encourage enterprises to invest directly in the emerging markets along the \"The Belt and Road\". With the \"The Belt and Road\" as the pilot project, China will radiate to the outside world to enhance China’s economic strength and the international discourse power of its currency. The role of the Asian Infrastructure Investment Bank and the Silk Road Fund should be brought into full play, and financial infrastructure should be improved.","PeriodicalId":154348,"journal":{"name":"2021 5th Annual International Conference on Data Science and Business Analytics (ICDSBA)","volume":"550 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117051440","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 the context of economic globalization and the integration of market economy, the increased correlation between markets leads to the enhancement of risk resonance effect, which leads to the contagion of risks among different markets, among which China is particularly affected by the fluctuation effect of American market risks. In view of this, this paper uses the BEKK-GARCH (1,1) model to explore the risk contagion effect between China and the United States during the period of January 2, 2001 solstice and March 19, 2021. The results show that, first, in the full sample interval, there is a two-way volatility spillover effect between the Chinese market and the American market and there is a Granger causality. The degree of volatility spillover from American to China is more significant. Second, in the four crisis intervals, the volatility spillover effects of China and the US show some characteristics different from those of the full sample interval. During the European debt crisis, there was a positive volatility spillover effect between the two markets, and the spillover degree of systemic risks in China’s market to the US market was more significant. During COVID-19, the US market risks had negative volatility spillover to the Chinese market. Third, both the Chinese and American markets are affected by their own fluctuations in the early stage with relatively large impacts and short duration, while the impact of the US on China lasts for about 7 periods.","PeriodicalId":154348,"journal":{"name":"2021 5th Annual International Conference on Data Science and Business Analytics (ICDSBA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114512394","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}
