The Development Trend

In recent years, 5G photonic technology has gradually gained increased attention from scholars. However, studies on 5G photonic technology have mostly focused on technological discussions or market development research, but have failed to identify the relevant key technologies from a comprehensive perspective. In particular, 5G photonic technology is an interdisciplinary technology that could create considerable potential business opportunities in the future, therefore, identifying related key technologies is crucial. Accordingly, the patents of 5G photonic technologies were used as the basis for analysis in this study, and a patent technology network for such technologies was constructed using network analysis. The results showed that the key technologies of 5G photonic technology are mainly related to optics, nanostructures, semiconductors, and material analysis, indicating an interdisciplinary feature instead of focusing only on one specific technological field. Additionally, the relevant technologies that have seen active development in recent years are mainly related to optical elements and semiconductor devices. Finally, a patentee analysis demonstrated that information technology companies were the key players in the development of 5G photonic technologies, and the semiconductor industry will have a crucial role in the development of such technologies. In this study, a patent technology network model was constructed to explore the development trend of 5G photonic technologies, thereby providing a reference for the government to promote these emerging technologies.

Owing to rapid development of the Internet and the rise of the big data era, microblog has become the main means for people to spread and obtain information. If people can accurately predict the development trend of a microblog event, it will be of great significance for the government to carry out public relations activities on network event supervision and guide the development of microblog event reasonably for network crisis. This paper presents effective solutions to deal with trend prediction of microblog events’ popularity. Firstly, by selecting the influence factors and quantifying the weight of each factor with an information entropy algorithm, the microblog event popularity is modeled. Secondly, the singular spectrum analysis is carried out to decompose and reconstruct the time series of the popularity of microblog event. Then, the box chart method is used to divide the popularity of microblog event into various trend spaces. In addition, this paper exploits the Bi-LSTM model to deal with trend prediction with a sequence to label model. Finally, the comparative experimental analysis is carried out on two real data sets crawled from Sina Weibo platform. Compared to three comparative methods, the experimental results show that our proposal improves F1-score by up to 39%.

This paper analyzes the spread of the COVID-19 epidemic in China, establishes a [Formula: see text] epidemiologic model that classifies the diagnosed population into asymptomatic, mild, and severe, and considers the condition of an isolated population. First of all, we theoretically analyzed the key problems of the disease-free equilibrium, stability, and basic reproduction number of the model. Then, combined with the actual data, the development trend of the epidemic situation is simulated and compared, and the influence of some important parameters is discussed in the model evaluation part. Finally, based on the theoretical analysis and numerical simulation results, we forecast the future development of the COVID-19 epidemic and put forward some reasonable scientific suggestions for the government to formulate a future epidemic prevention policy.

Contemporary college students are the main group that will create a new kind of China and promote China's economic development. This requires them to have a unique and sensitive perspective of development, education is not only the demand of China's economic structure transformation, but also in line with the development trend of global higher innovation education. 1000 college students from different grades and regions have fully understood the innovation education of our country through the questionnaire survey. In the past ten years, the government, universities in some regions and the society have analyzed the investment in education. In addition, this paper also compares the two-year survival rate of entrepreneurship projects between graduates with and without education from 2010 to 2017. Through the post-processing, statistics and comparison of the data, we find that most of the students have different degrees of willingness to start a business, but relatively few can put it into action. The main reasons are the lack of a reliable platform, innovative ideas can not be achieved, the lack of guidance of relevant economic theory knowledge, and the inability to implement scientific research achievements into specific entrepreneurial projects.

The Development Trend

As the stock with the highest stock price in China, Guizhou Moutai is favored by the public investors, and also focused by the local and central governments. However, in the whole investment market, in order to deal with the problem of information asymmetry between enterprises and investors, any rational investor will try to obtain more accurate enterprise information and pay attention to the analysis and suggestions of professionals, so as to ensure the safety of their investment and obtain considerable profits. Therefore, in order to reveal the accurate situation of the enterprise value under the continuous growth of Moutai group’s stock price, provide investors with relevant decision-making basis, and provide useful reference information for the government departments to regulate the liquor market. This paper evaluates the enterprise value of Guizhou Moutai Group by establishing FCFF model and using the historical data collected, and then the actual value of Moutai Group is calculated and a conclusion is drawn. The research shows that: the growth of Moutai Group’s stock price is in line with the development trend of the enterprise and the industry, and the enterprise value has a reasonable support, which is not unreasonably high. At the same time, the analysis shows that the growth ability, profitability and development ability of Moutai Group are relatively strong, and the enterprise has a strong development potential in the future.
