China Securities Co., Ltd. research reports indicate that tax IT is an important lever for the implementation of tax system reform. China's tax system has undergone multiple rounds of institutional reforms in the past 30 years, and information construction has been a crucial support and lever for financial and tax reform. Generally speaking, in the thirty years since the tax reform, the tax information system has gradually transitioned from the electronization of single-point functions to the circulation and regulation of a "nationwide whole". The data generated throughout the process not only provides decision-making support for tax management, but also has the potential to continue empowering social governance, and financial and tax IT suppliers are expected to continue to grow. It is recommended to focus on financial and tax IT related symbols.
