Building a new pattern of development is a development strategy put forward by China in the new era, aiming at achieving high-quality development and promoting all-round economic and social progress. The new development pattern is dominated by the domestic big cycle, and the domestic and international double cycles promote each other, forming a new pattern of all-round opening up. This strategy is not only a profound grasp of the law of China's economic development, but also a positive response to the changes in the global economic situation.

The core of building a new pattern of development is to optimize the economic structure and improve the quality and efficiency of economic development. In the big domestic cycle, it is necessary to deepen the supply-side structural reform, give full play to the huge potential of the domestic market, and promote industrial upgrading and innovation-driven development. At the same time, it is necessary to strengthen infrastructure construction, improve people's living standards and achieve the goal of a well-off society in an all-round way.

In the international double cycle, we will adhere to the basic national policy of opening to the outside world, actively participate in global economic governance, and promote the construction of an open world economy. By strengthening international cooperation and introducing foreign advanced technology and management experience, the international competitiveness of China enterprises will be improved. At the same time, we must actively promote the construction of the Belt and Road, strengthen mutually beneficial cooperation with countries along the route, and achieve common development and prosperity.

In a word, building a new development pattern is a strategic choice for China in the new era, aiming at achieving high-quality development and promoting all-round economic and social progress. The implementation of this strategy will strongly promote the sustained and healthy development of China's economy and make greater contributions to global economic growth.
