Under the current situation, China should firmly grasp the strategic basis of expanding domestic demand, which is determined by various unexpected constraints.

First, changes in the international environment. At present, the world economy is in deep recession, international trade and investment are shrinking sharply, the international financial market is turbulent, and international exchanges are limited. Economic globalization is facing a counter current. Some countries pursue protectionist and unilateralist policies, and geopolitical risks are rising. China is seeking economic development against the background of a more unstable and uncertain international cycle. In order to grasp the initiative of economic development, China must expand domestic demand.

Secondly, the global epidemic has a great impact on China's economic development. Take the manufacturing industry as an example. With the deepening of globalization, social division of labor is becoming more and more detailed, and the global industrial chain and supply chain are constantly expanding and deeply intertwined. If a link goes wrong, it will produce "Butterfly Effect", that is, systemic risk. Most of our enterprises are in a special link of the industrial chain, and some of them are at the low end of the industrial chain. With the spread of the epidemic around the world, some cities shut down, resulting in many enterprises either unable to produce or unable to sell. Therefore, China must start domestic demand, grasp the key industrial chain and supply chain in its own hands, and digest the goods originally produced for external demand.

Finally, China has the objective conditions to implement the strategy of expanding domestic demand. A country's economic development model is largely determined by resource constraints. Large countries have vast territory and rich resources, so it is possible to establish a relatively sound industrial chain, so the economy of large countries often has the characteristics of internal circulation. Today's China not only has the above characteristics, but also has the most complete and largest industrial system in the world. It has a strong production capacity, more than 100 million market players, 170 million talents with higher education or various professional skills, and a super large domestic demand market of 1.4 billion people, including more than 400 million middle-income groups. It is in the process of new industrialization and information technology At the stage of rapid development of urbanization, urbanization and agricultural modernization, we are fully capable of forming a development model based on expanding domestic demand. The above analysis shows that it is inevitable for China to form a development model based on expanding domestic demand.

But this is not the whole problem. What China needs is to speed up the formation of a new development pattern with domestic circulation as the main body and domestic and international double circulation promoting each other. In other words, China will not relax the international circulation and opening up. In a sense, without opening up, there will be no reform. Opening up enables us to see the outside world. Opening up gives us the Enlightenment of reform and clarifies what to change, where to go and where not to change. The key to opening up is the introduction of market economy, which is the most active factor in the world today. We must unswervingly follow the basic law of market economy and unswervingly reform and open up.

A higher level of opening up is the objective requirement of high quality and sustainable development of China's economy. China has entered a new era, which is characterized by high-quality economic development. For high-quality development, we must further open up at a higher level.
