Driven by the Internet big data intelligence, modern financial theory and financial engineering have kept pace with the times and entered into the era of intelligent finance. In the international financial academics and industry, intelligent finance has emerged as the latest stage of modern financial theory and financial engineering formally with the First International Workshop on Intelligent Finance (IWIF-I, 2004, Melbourne, sponsored by ANZ Bank). The follow-up IWIF-II and IWIF-III took place in Chengdu 2007 and in Beijing 2009 respectively sponsored by Southwest University of Finance and Economics (SWUFE) and University of Electronic Science & Technology of China (UESTC), and by the Chinese Academy of Sciences Forecasting Science Center and China Finance Online (NASDAQ: JRJC). The year of 2013 and 2014 are considered respectively as the first year of the big data and of the Internet finance in China. The truth is that what is underlying both the big data and Internet finance is intelligent finance as the scientific fundamentals and the core technologies. Theoretically, technologically and practically, intelligent finance aims at the intelligent design of financial systems, institutions and products, at the intelligent management of market risk, credit risk and operational risk, and at the intelligent automation of financial investment and trading as well as financing and financial operations. The fourth meeting on intelligent finance is lifted from the level of workshop up to the level of international conference on intelligent finance science, technologies, applications and management. Along with the extensive international corporations driven by the Belt and Road Initiative, the creation of Asian Infrastructure Investment Bank, and the internationalization of Chinese yuan, a new world financial order of dollar-euro-yuan triangle is emerging for the world economy. At the same time, along with the rapid development of Internet finance, e-commerce, Internet of things and Industry 4.0, the world economy is entering into a new era of intelligent economy. All these demand the intelligentization of financial systems, markets and management up into a new stage of full-scale development. This kind of requirement of the times and the market demand have posed new challenges to fundamental theories of modern finance, requiring to lift financial engineering to the science and technologies of intelligent financial engineering. Herewith involved are a number of outstanding problems – theoretical, technological and strategic. This Conference still takes the form of oral presentations and posters, including keynote speeches by the visionary financial strategists and world-class scholars and experts, leading-edge research reports and technological demonstrations from various frontiers of intelligent finance.
