The GDP of Song Dynasty accounts for 80% of the world. What is the exact source of this statement?

The GDP of Song Dynasty accounts for 80% of the world. There is no exact information about this statement. Generally, the official production records at that time shall prevail. It can be inferred that it accounted for 80% of the world according to the records of various countries at that time, because the output value of GDP was mainly provided by agriculture at that time, and China's agriculture was quite developed, so its GDP was naturally high.

The per capita GDP of the Song Dynasty reached US$ 2,280, accounting for 65% and 80% of the world's GDP, making it the richest dynasty in China's history. Moreover, Europe is still in the formation period of feudal dynasty, and China is in the transition period from Shang Yang's political reform to feudalism. The Song Dynasty was the only dynasty in ancient China that did not implement the policy of restraining business for a long time, and its productivity was much higher than that in Europe.

Agriculture was the most important production department in Song Dynasty. The development of agricultural production in Song Dynasty, in terms of breadth, is mainly manifested in the increase of cultivated land. Due to the continuous reclamation of the broad masses of working people, feudal countries in the Song Dynasty sometimes implemented measures to encourage reclamation. Some officials cared about farming and guided reclamation. Various types of farmland, such as express farmland, mountain farmland, Shatian, silt farmland, coated farmland and paid farmland, gradually increased, so there must be much more cultivated land than in the Han and Tang Dynasties. However, the official statistics of reclamation figures in Song Dynasty are obviously far from the actual situation.

Economy of Song Dynasty introduced the economic development level and situation of China in Song Dynasty. China in Song Dynasty was very rich. The Song Dynasty was the most prosperous era of economy, culture and education in the history of China, and reached the peak of feudal society. Chen, a famous historian, said: the culture of the Chinese nation has developed for thousands of years and reached its peak in the Zhao and Song Dynasties. Kaifeng, located in the center of eastern Henan plain, also known as Bianliang and Bianjing, was the capital of Song Dynasty 168. It was a famous cultural, economic, artistic and political center at that time, and its prosperity was unmatched by later generations. It was also the first city in China where Jews settled. From the middle and late Tang Dynasty, the economic center moved south and was finally completed in the Southern Song Dynasty.
