The exponential spread of the COVID-19 pandemic shook up global markets and caused major adjustments to the world economy. In this paper, we investigate whether these changes affected hedge fund return patterns. We decompose hedge fund index returns into Fama-French factors using data from 2017 – 2019 and compare it to decompositions using data from 2020 and 2021 to date. Our empirical results suggest that the Fama-French factor exposures changed on the conventional hedge funds. This has reflected that COVID-19 has an impact on the return patterns of the hedge funds we selected. The findings have implications for investors and major players in the investment markets. Our research is useful for predicting how the performance of hedge funds changes in market disruption.","PeriodicalId":118352,"journal":{"name":"Proceedings of the 2022 6th International Conference on E-Business and Internet","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124860722","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}

Promoting the cross-boundary integrated development of the leisure industry is an inevitable requirement of the social and economic development at the present stage. This paper takes Dongguan as the research area, constructs an evaluation index system of digital economy and leisure industry development, uses entropy weight method to evaluate the comprehensive development level of digital economy and leisure industry, and then analyzes the time variation trend of the coordinated development using coupling coordination degree, relative development model, and correlation analysis model. Results show the following. (1) From 2010 to 2020, the development level of digital economy and leisure industry in Dongguan fluctuates to a good trend. (2) In terms of development trend, from the digital economy lag, leisure industry lag to the synchronous development of both. (3) The coupling coordination shows an upward trend, developing from extreme disorder to mild coordination, but there is still a large room for optimization. Therefore, it is necessary to further improve the high-quality development of digital economy and leisure industry according to local conditions, improve their “coupling coordination degree”, and build a new system of digital leisure industry to realize the sustainable development.","PeriodicalId":118352,"journal":{"name":"Proceedings of the 2022 6th International Conference on E-Business and Internet","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124365325","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}

Service trade has become one of the important factors affecting a country's international competitiveness. At present, Laos' service trade has problems such as irrational industrial structure and weak capital. However, China's service trade development index ranking has remained at the 20th place in the world for three consecutive years, and the overall stability has been maintained. There is great trade complementarity in the service trade between the two countries. Based on the status quo of the service trade between China and Laos under the “One Belt and One Road” initiative, this article uses data analysis methods to study the competitiveness of China-Laos service trade, including China-Laos service trade value, comparative advantage index, trade competition index, and international market share etc., so as to draw the advantages and prospects of the development of China-Laos service trade, and finally put forward countermeasures to promote China-Laos service trade under the \"Belt and Road\" initiative.","PeriodicalId":118352,"journal":{"name":"Proceedings of the 2022 6th International Conference on E-Business and Internet","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127931026","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}

As it is known that most of the SMEs have an essential role in the country's economy growth, especially in developing countries. Therefore, an adaptation to technology is crucial for enterprises to implement. Unfortunately, most of the SMEs have not implemented a risk management system yet which it could create a threat to the sustainability of their enterprises. Risk management itself is important to have for enterprises as it can develop a strategy that is needed to compete with competitor, minimize and control risks from internal and external factor such as fraud, and to make the enterprise itself becoming more sustainable in the long run.

The target respondents ranged from 15 to 24 years old, as the young generation contributes to a large portion of the cosmetic market. 243 valid questionnaires were received from people who have purchased cosmetic products once in six months in Taiwan. The confirmatory factor analysis and structural equation model were adopted to analyze the relationship between three constructs: eWOM, perceived value, and purchase intention. The results suggest that perceived value impacts purchase intention positively and directly, while eWOM impacts purchase intention indirectly. This result regarding the consumer behavior of young customers could be utilized in the cosmetic industry's marketing strategy to enhance the sales profit and product competitiveness.","PeriodicalId":118352,"journal":{"name":"Proceedings of the 2022 6th International Conference on E-Business and Internet","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125258240","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 paper, we present a contextualized sentiment analysis model using a state-of-the-art FinBERT language model. We evaluate the performance of the fine-tuned FinBERT sentiment analysis model in the task of EUR/USD currency movement prediction. The results reported here confirm that the fine-tuned FinBERT is more effective than both the existing lexicon-based sentiment approaches and the survey-based Sentix index. In particular, substantial improvement in prediction performance is reported for different prediction horizons, ranging from 1-day-ahead to 180-day-ahead predictions.","PeriodicalId":118352,"journal":{"name":"Proceedings of the 2022 6th International Conference on E-Business and Internet","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131228179","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}
