The construction of domestic and international economic "dual-circulation" system is another mode of opening up China's economy under the new circumstances, which is also an important strategic principle in the formulation of China's "14th Five-Year Plan". According to this, major adjustments can be made to China's economic development strategy, and among them, the basic path is to further strengthen opening-up internally. Fundamental changes have taken place in the basic conditions and environment of the opening-up strategy in the past. Therefore, the past strategy of "economic globalization with export driven" should be transformed into the strategy of "economic globalization with domestic demand driven". The core essence is to attract advanced global factors to carry out innovation and entrepreneurship in China using the magnetic field effect of national ultra-large-scale market, and rely on economies of scale created by domestic demand and product differentiation to form a powerful internal force to promote export. To reshape China's economic circulation, firstly, domestic demand needs to be expanded through institutional reforms, and secondly, domestic demand should be used to siphon global scientific and technological innovation resources, induce technological and industrial innovation, and thirdly, basic industries requires to get advancement and the industrial chain needs to be modernized. In this way, a new domestic and international “dual-circulation” development pattern can be formed eventually. To achieve this, the key issue lies in opening-up at home, only by which can we promote domestic reforms, deepen opening to the outside, create a large domestic market, and organically connect domestic and international economic circulations. There are the following effective measures to improve the level of opening to the outside through the implementation of opening-up at home: reform the national income distribution system; promote the strategy of high-quality economic integration region by region; focus on removing the barriers to entry for private economy.
