Before unifying China, the rulers of the Yuan Dynasty adjusted their economic policies and paid attention to the protection of productivity and means of production. The official establishment of the agricultural management agency-the Department of Agriculture, to guide and supervise agricultural production; the first official agricultural book "Agricultural Mulberry Collection" in history was also issued nationwide to promote advanced production technology; Agricultural production and social economy have recovered and developed relatively quickly. Western astronomy, calendar, arithmetic, and medicine were introduced to China, and Chinese compasses, gunpowder, and printing were also spread abroad. The cultural exchanges between China and foreign countries and the political situation of unification have promoted the improvement of silk technology. The northern silk industry in the lower reaches of the Yellow River has rebounded, the division of labor in silk production has been meticulous, and the weaving technology has improved; in the south of the middle and lower reaches of the Yangtze River, the position of the center of gravity of silk production has been further consolidated and improved.
After the mid-Yuan Dynasty, the pattern of production areas has changed greatly, silk production in the north has declined, and the Jiangnan area has become more important. The reason is that, on the one hand, the colder climate makes the north unsuitable for sericulture production; on the other hand, the planting of cotton also makes the sericulture industry tend to be concentrated. The huge government-run weaving system was an important feature of silk production in the Yuan Dynasty, and it had a certain inhibitory effect on folk silk production.
