Key Technologies of Financial Digital Industry Innovation and Green Development Driven by Information Technology

With the development and application of Internet technology, the world has entered a new era of the Internet economy. Information resources worldwide are no longer limited by time or space, which significantly improves the operational efficiency of production and commerce. As an essential part of the digital economy, digital finance is developing rapidly. Compared with traditional finance, Internet finance and digital finance have the advantages of low informational and transactional costs, and efficient services, which bring more benefits to consumers and investors. In the traditional small and fragmented long-tail market, the availability of finance has been effectively improved through technology-driven development. However, the sound development of the financial digital industry is inseparable from the self-generated sense of innovation and the exploration of green and sustainable development within the industry. This paper shows the evolution of the innovation and development of the financial digital industry driven by information technology in recent years, summarizes and discusses the key technologies emerging in it, and analyzes its limitations and shortcomings. This work will provide some references for the green development of the current industry.
