The time is June 8, 2009 14: 00, in the conference room of School of Business Administration, Jiangxi University of Finance and Economics. This is the defense meeting for the doctoral thesis of industrial economics in Jiangxi University of Finance and Economics in 2009. Professor Huang Youguang, an internationally renowned economist, said to the respondent sitting opposite him, "This doctoral thesis has won the top universities in the world: Harvard and Princeton, and it is the best thesis ... It is one of the two best doctoral theses I have ever seen, and the other is from Yang Xiaokai." The defense meeting cancelled the 30-minute preparation for the respondent to ask questions to the judges, and the judges and the respondent immediately answered the questions. So the whole defense meeting became an academic seminar. Professor Huang Youguang laughed several times, while Professor Pang Chun, another young scholar of Monash University's new classical school, frequently stood up to refute. All this is because of Chen and his doctoral thesis, a student of Jiangxi University of Finance and Economics who has been studying for seven years behind closed doors. There is a detail in the defense process. Pang Chun's remarks have been fierce throughout the defense meeting, and his comments are also extreme (probably because Chen Yizhi disagreed with adding the words "emerging classical economics" to the title, insisting that the methods used in the paper were more the evolutionary analysis methods of nonlinear industries independently created by himself, and even claimed to have created another branch of economics in the paper, which he was very dissatisfied with). Professor He was a little embarrassed and silent (perhaps because he was a mentor in Beijing for many years, so he was a little ashamed), while Professor Huang Youguang was full of praise for Chen. I believe the respondent will thank Professor Huang for saving his life. Professor Huang received Chen's paper a few months ago, printed it out immediately, read it from beginning to end, and decided to get angry.

This doctoral thesis has a total of 800,000 words (the appendix also has nearly 654.38+10,000 words), with a visual observation of nearly 1000 pages (the shock at that time was only seen in the nearly 1 000 pages of foreign references listed in Wang Tinghui's monograph on micro-control mechanism design). From Chen's statements and questions, we can see that the author tries to integrate the whole economic framework by using the method of ultra-marginal analysis along the research track. This paper criticizes the views of 75 famous economists. Prove and expand some assumptions and theorems of emerging classical economics; This paper discusses the ultra-marginal analysis of the formalization of "government specialization" division of labor; Evolutionary game theory is used to explain China's 5,000-year historical process and industrial development in 30 years of reform and opening up. Using mathematical software to simulate the origin of enterprises, and taking Nanchang and other enterprises as cases to verify the model. Undoubtedly, from the division of labor and specialization to the riddle of Needham, the origin of enterprises is almost a long-debated problem at home and abroad, which shows the author's ambition. From the author's research on nearly 400 monographs from Yang Xiaokai and Huang Youguang to Braudel and Aoki Masahiko, as well as the application of ultra-marginal analysis, evolutionary game theory and computer simulation experiments (impression: Gintins &; Intestines, and axelrod's famous "tit for tat" experiment; It is the most difficult and cutting-edge tool and method in China's economics. In his defense, Chen accidentally said that he used the field investigation method only found in sociology to observe the division of labor and specialization of enterprises. We can also see the author's profound mathematical knowledge and hard work in the past 10 years (his extensive research fields and excellent application of mathematical tools remind me of Wang Dingding and his attempt to integrate the whole social science framework. But the gap is that Tintin's philosophy and other people's literary knowledge can only make us look up.

I still remember having dinner with Chen once and being there. Someone asked, "haven't you finished your paper yet?" "Ha ha, no" Han Han replied. "Oh, why? It's been seven years. A boutique? "Satire is fearless. Chen has only a wry smile. Of course, this is when Chen is still unknown.

At the end of the defense, Mr. Fang gave Chen a sentence: "After ten years of grinding a sword, the frost blade has never tried."
