Xu, director of the National Development and Reform Commission, pointed out that "five major developments" are the core content of the "Thirteenth Five-Year Plan" proposal. Innovation is the first driving force for development. Under the new normal, the biggest challenge facing China is to cross the middle-income trap. To break through this problem, the fundamental way out is to realize industrial upgrading through innovation. At the same time, promote coordinated development. Xu pointed out that there are three outstanding problems in China's coordinated development: first, the contradiction between urban-rural dual structure and urban internal dual structure is still outstanding; Second, the regional development is unbalanced, and the imbalance between the eastern, central and western regions and the northeast region; Third, the level of social civilization and national quality do not match the level of economic and social development. Therefore, during the "Thirteenth Five-Year Plan" period, we should continue to promote regional coordination, urban-rural integration, and coordinated development of material civilization and spiritual civilization in accordance with the requirements of coordinated development. Besides, we must promote green development. Xu said that China's long-term accumulated air, water and soil pollution problems are still outstanding, and the people's voice for improving the ecological environment is also very strong. During the "Thirteenth Five-Year Plan" period, we should adhere to the basic national policy of saving resources and protecting the environment, accelerate the construction of a resource-saving and environment-friendly society, promote the development of a green and low-carbon cycle, and make contributions to the ecological security of China and the world. Xu said that it is necessary to promote open development. Today, China has become the world's largest trader of goods, the largest foreign exchange reserve country, and the scale of attracting foreign investment ranks among the top in the world. China and the world economy have formed a pattern in which you have me and I have you. Therefore, during the Thirteenth Five-Year Plan period, we must develop a higher level of open economy, actively participate in global economic governance, and build a wider range of stakeholders. Finally, promote the development of * * *. Xu said that during the Thirteenth Five-Year Plan period, we should insist on development for the people, development depends on the people, and development results are shared by the people.
