The Qing government tried to strengthen its rule at home and carry out national "self-defense" abroad through the "closed door policy". As a means of passive defense, this policy has played a certain role in national self-defense in the approaching and fierce foreign aggression of western capitalism. But its greater influence is that it seriously hindered the progress and development of modern China society. China has been isolated for a long time, which has seriously hindered the development of domestic commodity economy and capitalism, and made its economy, culture and science and technology increasingly lag behind the West. It is "standing still", which is not conducive to the normal communication between the Chinese nation and all ethnic groups in the world, to China people's understanding of the world, to the world, and to learn from the excellent ideology, culture and advanced science and technology of all ethnic groups in the world, thus leading to the passive beating of modern China. Under the influence of the closed-door policy, China's economy has not changed much; (2) During the Second Industrial Revolution, China was still under the feudal rule of the Qing Dynasty, and the Westernization Movement only learned western military technology and science and technology to maintain the feudal rule, which soon failed; The introduction of foreign capitalist equipment, on the contrary, continued to plunder in China through war and capital export; The development of Chinese national capitalism is extremely slow; (3) During the third scientific and technological revolution, due to the long-term hostility, blockade and encirclement of imperialist countries, China did not have a peaceful environment for the development of scientific and technological revolution and lacked normal exchanges; After the founding of New China, influenced by the highly centralized political and economic system of the Soviet Union, the "Left" trend of thought flooded, the intellectual policy was not implemented, the development of education was often impacted, and science and technology lost the opportunity for development.

The closed-door policy blocked the foreign trade of the Qing Dynasty, which was not conducive to economic development. The rulers of the Qing Dynasty claimed to be a powerful country in China, which seriously affected the progress of China culture. Being isolated from the world means that we can't see the changes in the world situation, and we haven't learned advanced scientific knowledge and production technology from the West in time, which makes China gradually fall behind in the world. The closed-door policy of the Qing Dynasty seriously hindered the development of other production and the progress of science and technology, and the backwardness of science and technology led to the backwardness of military forces. The Qing dynasty was in a weak period of feudal society, and feudal relations of production had begun to hinder the development of productive forces. The closed-door policy makes it difficult for advanced systems to enter.
