| dc.title | Blockchain as an example : a study of venture investment to network security in Mainland China | en_US |
| dcterms.abstract | The network security industry mainly provides products and services to ensure network reliability and security. Traditional product forms mainly include firewalls, anti-virus products and so on. In a broad sense, network security mainly refers to all system-related device security, data security and content security. In mainland China, network security is becoming an increasingly serious issue. Network security is becoming an important factor affecting the development of the Internet in China and an important safeguard for national security. At present, China's network security industry is developing rapidly, the network security product system is becoming more and more complete, and the vitality of the industry is increasing. The market size of network security in mainland China is currently estimated to be over 100 billion yuan. However, mainland China's network security spending is far below the world's advanced level and below the global average, so mainland China's network security industry still has a lot of room for development and will be in a long-term period of rapid growth. | en_US |
| dcterms.abstract | Both the government and enterprises in mainland China attach great importance to the development of the network security industry. Driven by the twin wheels of policy support and favorable market conditions, the activation of capital trading activities of network security enterprises has increased significantly in the past, with a large number of investment institutions pouring into the market to fuel the development of the industry. From 2010 to 2019, the cumulative number of network security enterprises involved in capital operations reached nearly 300, with nearly 600 cumulative trading events and transaction amounts reaching nearly 80 billion. The total market value of listed network security enterprises grew from less than RMB 10 billion in 2010 to more than RMB 500 billion, achieving a 50-fold increase. In view of the good development prospect of the network security industry and the increase in policy support, China's network security industry continues to be favored by capital, with the financing amount increasing year by year. from January to July 2020, the number of financing for enterprises in the network security market was 35, with a total financing amount of 7.42 billion yuan. | en_US |
| dcterms.abstract | Therefore, this study will focus on the future development of network security industry in mainland China and make some comparisons with the development of network security industry in other countries. The role of network security in today's world is very important, the problem of network security with the progress of computer technology and increasingly prominent, so network security technology needs to be further developed to adapt to the current situation. As a representative of the application of emerging technology, network security technology has been the attention of venture capital, network security technology research and development and market expansion is also less complementary to the assistance of venture capital, so this study will do research on the concern of venture capital on the development of network security technology, and from which we choose a subdivided direction of the technology as a case study. After our initial research, we found that blockchain technology is currently sought after by venture capital, so we will analyze blockchain technology as a case study. | en_US |
| dcterms.abstract | Our first contribution is that we analyze thousands of startup businesses. Our dataset includes information on the funding round dates, investors, and the professional and educational background of the company's pioneers. This data's exploratory analysis reveals intriguing properties regarding the progression of funding phases for startup companies and factors influencing their success. Moreover, we collect the startup business information of US and China. Through our data mining, we can quantitatively analyze the commonality and difference between the blockchain industry startups of US and China. | en_US |
| dcterms.abstract | Our second contribution is the prediction of startups' winning possibilities. We adopt deep learning prediction models and do the feature engineering on the startups' information, e.g. funding rounds, investors, team members, industry. Moreover, we adapt matrix factorization into our proposed prediction model. We extract the common latent space to describe the commonality between US and China blockchain VC. Then we use their unique characteristics to predict the winning possibility of startups. | en_US |
