With the continuous development of China's capital market, an increasing number of enterprises aspire to raise funds through the capital market to continuously expand and strengthen their business. The feasibility study report on the variable frequency series resonance fundraising and investment project is a written report that assists enterprises planning to go public in completing the filing and approval of fundraising and investment projects before an IPO, and in coordinating with securities firms, providing necessary support for the company's prospectus. The design of the fundraising and investment project should combine the market research report of the specific segment and the company's own characteristics, reasonably forecast the project's prospects and profitability, accurately describe the logical relationship with the company's core competitive advantages and sustained profitability, and demonstrate its feasibility, necessity, and controllability, fully aligning with the CSRC's review approach to ensure approval. Issues related to the use of raised funds include the necessity of financing, whether there is a clear direction for the use of raised funds, whether the fundraising and investment project has clear profit prospects, and whether preparations for the use of over-raised funds are sufficient. Among the companies rejected for ChiNext IPOs, nearly half had issues with the use of raised funds, indicating that the fundraising and investment project is a critical part of the CSRC review process. However, the road to listing has never been smooth, and many enterprises have failed along the way. Statistics show that from 2007 to 2011, the CSRC reviewed 1,226 companies 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 previous understandings of their main business in the design of fundraising and investment projects. For example, a company expanded from subway business to high-speed railway business through its ChiNext listing, and another company extended from building intelligent services to building energy-saving services. Many enterprises have also made significant breakthroughs in the proportion of raised funds allocated to R&D centers. For instance, an IT company allocated about 50% of its total raised funds to its R&D center, and a biopharmaceutical company allocated over 40% of its total fundraising to its R&D center. In fact, in certain fields, R&D capability equates to sustained profitability. The rationality of fundraising and investment projects has always been a focus of the CSRC, and a reasonable and scientific feasibility study for such projects has become an important part of supporting a company's successful listing. The feasibility study for a fundraising and investment project must start from the overall system, analyzing and demonstrating multiple aspects such as technology, economy, finance, commerce, environmental protection, and law to determine whether the construction project is feasible, providing a 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. It should fully consider the CSRC's requirements for the use of raised funds, market prospects, product technological content, environmental impact, and compatibility with the company's existing management and sales capabilities. A reasonable feasibility study for a fundraising and investment project is key to passing the review.
