With the continuous development of China's capital market, more and more enterprises are determined to raise funds through the capital market to continuously expand their business. The feasibility study report on the fundraising investment project for power frequency withstand voltage test equipment is a written report that assists enterprises planning to go public in completing the filing and approval of fundraising investment projects before IPO, and in coordinating with securities firms to provide necessary support for the company's prospectus. The design of the fundraising investment project should combine the market segment report and the enterprise's own characteristics, reasonably predict the project prospects and profitability, accurately describe the logical relationship with the company's core competitive advantages and sustainable profitability, and ensure its feasibility and full compliance with the CSRC's review thinking to pass the CSRC review. Issues related to the use of raised funds include the necessity of financing, whether the raised funds have a clear direction of use, whether the fundraising investment project has a clear profit prospect, whether the preparation for the use of over-raised funds is sufficient, and whether there will be blind expansion. Among the enterprises rejected for IPO on the ChiNext board, nearly half had problems with the use of raised funds, indicating that the fundraising investment project is a very critical part in the CSRC review stage. However, the road to listing has never been a smooth one, and many enterprises have failed on the road to listing. Statistics show that during 2007-2011, the CSRC reviewed 1,226 enterprises for initial public offerings, of which 228 were rejected, with a rejection rate of 18.6%, making strict review the norm. Many enterprises have broken through their previous understanding of main business in the design of fundraising investment projects. For example, an enterprise extended its business from subway to high-speed railway through listing on the ChiNext board, another extended from building intelligent services to building energy-saving services, and another transformed from vaccine marketing to independent vaccine R&D and production. Many enterprises have also made significant breakthroughs in the proportion of raised funds invested in R&D centers. For example, an IT enterprise invested about 50% of the total raised funds in its R&D center. In fact, in certain fields, R&D capability equals sustainable profitability. The rationality of fundraising investment projects has always been a focus of the CSRC's attention, and reasonable and scientific feasibility studies of fundraising investment projects have become an important part of supporting enterprises' successful listing. The feasibility study of fundraising investment projects must start from the overall system, analyze and demonstrate multiple aspects such as technology, economy, finance, commerce, environmental protection, and law, to determine whether the construction project is feasible and provide scientific basis for correct investment decisions. The feasibility study of a project is a continuous process of analysis, research, evaluation, and decision-making for a multi-factor, multi-objective system. It requires the cooperation of professionals with knowledge in various fields to complete. It should fully consider the CSRC's requirements on the use of raised funds, market prospects, product technology content, impact on the environment, and matching with the company's existing actual management capabilities and sales capabilities. A reasonable feasibility study of fundraising investment projects is the key for enterprises to pass the review.
