After dinner at home, Xu Haodong went out for a walk alone, the days in late autumn were not as long as the nights, just after six o'clock, it was dark. Out of Bayi Road to the north is Hongqi Road, the brightness of the street lights on Hongqi Road is not high, and it is not necessary to see people's faces clearly, but Xu Haodong is free from being disturbed.

For Xu Haodong, who is busy with work, taking a walk is also a kind of enjoyment, but tonight's walk has ulterior motives, and rest is just an excuse.

The north end of Hongqi Road is connected to Zhongshan Middle Road, and if you walk through Zhongshan Middle Road, you will leave Nancheng Street and come to Zhongcheng Street.

A private car stopped on the side of the road, and when Xu Haodong approached, the back door of the car opened silently, and in a blink of an eye, Xu Haodong had sat in the car, and the car ran up with a whoosh.

In addition to Xu Haodong, there was also a driver in the car, and this driver was none other than Ding Shangping, deputy director of the Municipal Public Security Bureau in charge of criminal investigation.

In the last secret review of the March 17 arson murder case, Ding Shangping not only made great contributions, but also re-emerged from the mountain and was transferred back to the city bureau for promotion, and Ding Shangping and Xu Haodong established a deep revolutionary friendship.

"Lao Ding, how is the work?"

"Secretary Haodong, the incidence rate of criminal cases in the city has been declining month by month, the public security situation has continued to improve, and it ranks among the top ten in the province. At present, in our criminal investigation system, we can calmly deploy one-third of the police force to review the backlog of old cases and suspicious cases of the past few decades. According to your instructions, we have made a plan to review all the criminal cases of the past 35 years in three years. ”

"How's the book?"

Ding Shangping smiled, "At least I'm not good myself, my little culture, I can make do with a single case." However, I recommend one person to the leader, and that is Su Maoxiong, an instructor at the Zhongcheng Police Station. This kid has always liked to read, and recently he has been reading books on economics, and the last time we handled a case together, he said it to the truth, and he talked about us in a fog. ”

Xu Haodong sighed, "Yes, then I'll ask him for advice later." ”

Ding Shangping said: "Anyway, we all think that he has the ability to be the leader of the township, and it is too condescending to be in the police station." ”

Said Cao Cao, Cao Cao arrived, at an intersection, as soon as the car slowed down, two people got into the car, it was Zhang Ping, the director of the Zhongcheng Police Station, and Su Maoxiong, the instructor, Zhang Ping was sitting in the passenger seat, and Su Maoxiong happened to be sitting next to Xu Haodong.

The sedan drove up the ring road and slowly walked around.

After greeting, Xu Haodong didn't talk about business, but asked with great interest about Su Maoxiong's reading, "Maoxiong, I heard that you have been reading economics recently, can you talk about economic theory?" ”

Su Maoxiong was embarrassed, "Secretary Haodong, how dare I get an axe." ”

Xu Haodong smiled and said, "Excessive modesty is pride. ”

Ding Shangping and Zhang Ping encouraged Su Maoxiong together, and Su Maoxiong mustered up courage.

"Secretary Haodong, I'm talking nonsense, please criticize and correct." Su Maoxiong said: "As a discipline in contemporary social science, economic theory has never had a theory first, and then used theory to guide practice, but through the analysis and summary of phenomena in social activities, so as to form a set of descriptive theories. First came market activity, and Adam Smith believed that there was an omnipresent and mysterious hand in control, which led to the so-called market theory. And there was government intervention first, and then there was the so-called Keynesian theory. ”

Xu Haodong said: "This head is a good start. ”

"The discipline of economics has no empirical evidence, only retrospective and forward-looking, and is not strictly objective science. Although modern economics has introduced mathematics to build models, each model is produced by a different person and reflects a different ideology. If the economic data of the past is put into the model and the conclusion is roughly consistent, the economic theory that constructed the model is considered correct, and the economist who proposed the economic theory hopes to use this theory to guide economic life. However, the conditions in reality have changed, and whether the data that conform to this model in the past will still be obtained, most economists in China do not think much about this, which is the reason why economic reform is now carried out according to the theory of economists, but the more it is changed, the more outrageous it becomes. ”

Xu Haodong said: "Yes, 100 economists can create 100 sets of economic theories. ”

"The mathematical model is still reliable because the socio-economic conditions at that time are relatively close to the spectrum of the environment when it was theoretically derived. From this point of view, economics is an empirical discipline, and to put it bluntly, it is like fortune telling. There are many schools of fortune-telling economics in the West, but there are only two main ones that are popular in China: Keynesian and neoliberal microeconomics. In 1980, Lawrence Klein, who came to China to give lectures, belonged to the Keynesian school. The Keynesian school emphasizes full employment and state intervention, and in economics, Keynesianism is a branch of macroeconomics. Macroeconomics, also known as general economics, is the study of the overall economy, through the study of aggregate economy, in order to solve the problems of unemployment, inflation, economic fluctuations, and the balance of payments. ”

Xu Haodong nodded, "Yes, you continue." ”

"Symmetrical to macroeconomics is microeconomics, and neoliberal economics is microeconomics. Microeconomics takes a single economic unit as the object of study, centered on price analysis, and analyzes how a single producer allocates limited resources to obtain maximum profits. The source of microeconomics is Adam Smith's The Wealth of Nations, that is, market-led economics. At present, most of China's mainstream economists hold the view of neoliberal economics. It is not surprising that as our economy struggles to pursue a transition phase, economists instinctively reject the planned and intervening Keynesianism of the economy, and instead embrace the neoliberal economy, which sounds pleasant. This is mainly due to the stupidity of economists, who only know that the planned economy is not good, but do not analyze whether China practiced a planned economy at that time, and whether the planned economy to an appropriate extent is helpful to economic development. ”

Xu Haodong smiled slightly, "So, what kind of economy was practiced in my country at that time?" ”

"At that time, our country practiced a command economy, not a planned economy, and the former Soviet Union was a planned economy. From the time of Stalin to the era of Brezhnev, a strictly planned economy was practiced, and they have always been in charge of experts and factory directors. In particular, economists take the neoliberal economy as the only criterion to measure all economic and social phenomena, so much so that they deviate from common sense, justice, and axioms without knowing it, which is ridiculous beyond absurdity. There is no single theory or doctrine that is a panacea for all ills, and mainstream Chinese economists generally do not understand this common sense. ”

Xu Haodong smiled, "Haha...... Maoxiong, do you understand Qiu Youke's economic theory? ”
