Inventor and founder of financial ecology, chief investment officer of American Global Securities, vice chairman of the board of directors of American Institute of International Financial Securities, consultant of the board of directors of Toronto Stock Exchange, consultant of Boao Forum for Asia, director of Canadian Venture Capital Exchange, member of the investment and financing master plan of Boao Watertown, the development strategy committee of Boao Watertown, consultants or directors of many Chinese and American enterprises, and American Global Securities Fund founded by professors from many Chinese and American universities or distinguished professor, which is the first fund in the world to integrate the world's major financial product systems in 2003. The financial tree system, systematic finance and financial ecology he invented and founded are not only unique, advanced, perfect, practical and effective management system, theoretical system and teaching system in the world, but also enable ordinary people to live for a few days in the planned economy era when food stamps, cloth tickets and other bills prevailed. In an era when most people in China have never heard of the word "finance", David Ding is not sure what "finance" is. However, it seems that "finance" is higher than economy. He resolutely took the risk of "the best in the world" and went to the United States to study for more than 20 years. With his solid theoretical foundation, rich practical experience and accurate forward-looking judgment, Professor Ding was invited to become a member of numerous Chinese and foreign institutions, regulatory authorities and enterprise managers, such as the US Department of Commerce, the US Department of Justice, Merrill Lynch, Hewlett-Packard Company and Japan International. At the same time, Professor Ding has designed and taught various high-end cutting-edge courses for dozens of Chinese and American universities, such as Peking University, Tsinghua,, National People's Congress and Graduate School of Chinese Academy of Sciences, and trained a large number of financial and business management talents for China and the United States. Melting. Learn what it usually takes several years to learn, and learn what you can't learn, which you will never forget. Thousands of people from all walks of life in the world have benefited a lot from it. In order to further prevent the subprime mortgage crisis in the United States from turning into a global systemic financial crisis, on February 3, 2007, Professor 65438+ Ding suggested to the top leadership of China and pointed out that if even China, which was slightly involved in the subprime mortgage crisis in the United States, could not bear the impact of this crisis, it would be inevitable that this crisis would turn into a global systemic financial crisis, and China would also suffer huge losses. Suffering from the biggest trauma since the Great Depression of the last century, the financial and economic system in the United States and even the whole world almost collapsed. The American government finally woke up from a dream and was surprised to find that the financial supervision system in the United States was fragmented. "The railway police are in charge of each other, isolated from each other, and they only know one, but they don't know the other. It is not only seriously lagging behind, divorced from reality, but also violated. The financial system is very strong, either all-inclusive or seemingly incomprehensible. This is why in recent years, the regulatory authorities failed to realize that the financial system in the United States has developed to such a bad state, failed to find the trigger of the crisis and its ins and outs in time, and failed to take effective measures in time, which eventually led to the "full fall" of global finance. The deep or fundamental reason of this crisis is that global financial practitioners and regulators don't understand the property, ecosystem and systematicness of finance. Facts have proved that if you don't understand the essence, ecosystem and systematicness of finance, you won't know the real finance, let alone how to predict and avoid the financial crisis. In order to change the status quo, US Treasury Secretary Henry Merritt Paulson officially announced the major reform plan of the US financial supervision system on March 3 1. This will be the most comprehensive financial reform in the United States and even in the world. Its significance is extraordinary and significant, because it changes not only the financial supervision system, but also the re-division of financial markets, rules of the game, laws and regulations. With the above changes, the outdated financial knowledge, education and accounting standards will also face comprehensive reform. Due to the dominant position of American finance in global finance, the comprehensive reform of American finance will inevitably lead to the comprehensive reform of global finance, because global financial integration is an unchangeable reality. This will be the most important step for all financial practitioners and regulatory authorities to sell the objective laws of finance, namely financial attributes, ecosystems and systems, which will affect each of us in the future. This will be a lasting reform. However, Professor David Ding has been far ahead of the times, because he has done what others want to do in the future. Through financial tree system, system finance, financial ecology, etc. You can clearly see where finance comes from and where it goes ... Although Professor Ding has warned the world many times about the possible results before the crisis, he regrets that the book "Financial Tree" was not published in the United States as scheduled before the crisis, because the book illustrates how the crisis of this financial tree in the United States will occur and how to avoid it. Perhaps the timely publication of the book can play a role in avoiding this crisis.
