1.1 Background
The investment field is wide and the entry method is flexible. Judging from the current investment situation of venture capital in the field of new energy, almost all kinds of new energy projects have the shadow of corresponding venture capital. In addition to relying on formal venture capital companies to enter, there are many venture capital in the form of equity investment in the creative or start-up stage of new energy projects. In terms of investment fields, the largest number of venture capitals are in R&D and industrialization projects related to biomass energy, solar energy and wind energy. Investment is more cautious and the degree of specialization is low. Although new energy has provided a huge stage for venture capital, all kinds of venture capital have appeared one after another and have already made gains. But judging from the current investment quota of venture capital in new energy projects, it is quite limited. Such as Sequoia Capital, IDG and other large international venture capital institutions, the previous single investment in the fields of advertising creativity, chain operation, and biotechnology often exceeded 10 million US dollars. The investment in new energy projects is relatively cautious, the single investment amount is not high, and there are few projects exceeding 5 million US dollars. This shows that the international venture capital institutions mainly wait and see for new energy projects, which are still in the trial stage. The outlook is uncertain, and the profit model is single. Although venture capital has played an important role in promoting the development of new energy economy(Kuzminov et al., 2017)); but most of the venture capital invested in new energy projects is still in the sowing stage or cultivation stage. It takes more than 6 years for a high-tech to go from research and development to industrialization, even if it progresses smoothly. It is only in recent years that China's venture capital has entered the new energy industry on a large scale, so there are very few new energy venture capital projects that have achieved industrialization and entered the harvest period. Due to the small amount of investment and the short development time of the current new energy projects, most of them do not meet the above conditions. Therefore, the venture capital investment in most new energy projects is in a dilemma: either continue to make additional investment until successful exit; or give up the initial investment of the project. Some new energy projects are on the verge of bankruptcy and liquidation due to insufficient follow-up investment, and there are many conflicts between venture capital institutions and entrepreneurial teams. In order to make full use of the abundant data and information resources, scientists continue to explore, create statistical inference technology characterized by the use of structured sample data analysis, and create a data mining method characterized by the use of structured massive data analysis. The emergence of mining not only greatly adapts to the characteristics of the information explosion era, but also brings about a change in research paradigm. Research paradigms driven by theoretical models are gradually being replaced by theoretical model-driven + data-driven research models. The rise of the data-driven research paradigm has not only fundamentally improved the dependence of traditional statistical analysis on sample data, and thus avoided the risks caused by incorrect distribution settings, but also provided corresponding methods and tools for people to re-understand socio-economic connections (Tremblay and Hevner, 2021). Dadi has enhanced the ability to realize the economic value of data and information. Under the premise of the vigorous development of the new energy economy industry, an investment and financing mechanism to support the development of the new energy economy industry has been established to effectively integrate the development of modern new energy economy enterprises with modern financial tools. As a new investment method to support the development of new energy economic enterprises, the role of venture capital in economic life has become increasingly prominent. Seeking new energy and transforming the economic growth model all need to rely on new technologies and venture capital will play an important role in the development of the new energy industry. My country's new energy venture investment started late, but it has developed rapidly. Because new energy venture investment is a long-term equity investment, compared with conventional equity investment, it has irreversibility and multi-level investment flexibility. Therefore, the method of combining the net present value method and real options is used for new energy it is more meaningful to evaluate the value of the project.
