Wei Shangjin s character works, how to evaluate Wei Shangjin

1. What impressed me the most about Wei Shangjin's research on corruption was not his highly cited research on corruption and transnational investment, but his research on tax evasion and tariff rates on the mainland. Before Wei Shangjin, most of the empirical studies on tax evasion were models or estimates, and there should be no empirical evidence linking tax rates with tax evasion.

Wei Shangjin used Hong Kong's export data and the mainland's import data to compare the criteria, and found that the mainland's imports from Hong Kong, both in terms of import quantity and **, are lower than Hong Kong's export data, and there is a phenomenon of marking low-priced goods on ** goods. Specifically, he also found that a 1% tax rate on the mainland would lead to a 3% tax evasion problem.

Around the end of the year, Roderick et al. found that the complexity of China's exports is higher than that of countries with the same income, and Wei Shangjin also studied this. It is relatively easy to compare the complexity of the export products of different countries in the same year, but not at the same time.

It is more difficult to compare exports. For example, radio, Walkman and *** are also assembled, how is the latter more complicated than the former? However, only by studying the increasing complexity of each country's exports can we judge whether the country's national and industrial policies are successful, so it is very important to design this index.

Wei Shangjin took a different approach and compared the exports of Japan, the United States, and the European Union (G3) in the same year with those of Japan, the United States, and the European Union (G3) in the same year, and the closer the country's industrial exports were to each other, the more complex the products would be. This solves the problem of comparing the complexity of exports over time, because while some products have disappeared with the times, products have changed in both developing and developed countries. At the same time, Wei Shangjin found that China's development zones are conducive to increasing the complexity of exports, which shows that China's industrial policy has a certain effect.

3. Wei Shangjin's research on the sex ratio and the savings rate of residents is believed to be very many.

After familiarity, many people may not know his inference about this. He argues that China's high sex ratio is responsible for the higher savings rate and higher entrepreneurial ratio of Chinese parents, so the reason for China's large current-account surplus is not because of an undervalued exchange rate, but because of the competitive savings of residents.

He compared the corporate savings rates of different countries and found that China's corporate savings rate, although much higher than that of the United States, is about the same as that of other countries in East Asia. Wei Shangjin's reasoning is so important that it is not enough to analyze the renminbi exchange rate based on the current account surplus and foreign exchange reserves, so he pointed out in 2010 that the renminbi's substantial undervaluation may be an "illusion", and around 2014 he suggested that the overvaluation of the exchange rate was the main problem facing developing countries.

Wei Shang (?) —157 BC), a native of Huaili (now Xingping County) in the Western Han Dynasty. Emperor Wen of the Han Dynasty was the Taishou of Yunzhong (now northeast of Tuoketuo, Inner Mongolia).

He guarded the border, defended against the Xiongnu, and fought meritorious. Later, because the number of enemies killed reported to the imperial court did not match the reality, only six heads were missing, and he was cut down and investigated. Feng Tang, the director of Langzhong, thought that Wei Shang had been mishandled, and directly admonished the emperor in person, and Emperor Wen sent Feng Tang to Yunzhong with a talisman to pardon Wei Shang's sins and restore him to the official position of Taishou in Yunzhong.

He governed the army strictly, cared about his subordinates, and used all the military taxes and taxes to reward his subordinates, and used his own money to kill cattle and sheep, and feasted his subordinates once every five days, and his subordinates supported him very much. The momentum of the whole army is very high, the stones are thrown over the distance, everyone is vying for the first, and the military prestige is greatly shaken. The Huns were afraid.
