Its basic connotation is: first, all-round development; The second is coordinated and sustainable development. The so-called all-round development means paying attention to economic, social, political, cultural and ecological development; The so-called coordination means that all aspects of development should be interrelated, mutually promoted and positively interacted; The so-called sustainability means that we should not only consider the needs of current development and meet the basic needs of contemporary people, but also consider the needs of future development and think about future generations. The essence of coordinating urban and rural development is to promote the transformation of urban-rural dual economic structure. China is in the process of profound social transformation, and the transformation from urban-rural dual economic structure to modern social economic structure will be the basic trend of social and economic development in China in the next few decades. In the past, the "three rural issues" were mainly agricultural production issues. Now, while making a fuss about the word "agriculture", we should pay more attention to finding the way out of "agriculture" and promote the fundamental solution of the problems concerning agriculture, rural areas and farmers through "industrialization, urbanization and marketization". The next economic reform should focus on establishing a system conducive to changing the dual economic structure of urban and rural areas, and national policies should give greater support to solving the "three rural issues". The essence of coordinating regional development is to realize the common development of the region. It is an established policy of the state to maintain the momentum of rapid development in relatively developed areas and support the development of backward areas. The regional gap is not only the gap between the east and the central and western regions, but also the gap between provinces, autonomous regions and municipalities directly under the central government, as well as the gap between the internal regions of provinces and autonomous regions. The problem of regional disparity should be gradually solved in the process of industrialization, urbanization and marketization. The essence of coordinating economic and social development is to achieve all-round social progress on the basis of economic development and enhance the welfare of all people. With the solution of the problem of food and clothing and the deepening of reform, social problems in economic development have become increasingly prominent. Many problems in the field of social development are directly related to the inadequacy of government functions in the process of economic transition, and government functions must be changed. Social security, science and technology, culture and education, public health and medical care all have their own particularities. The government must shoulder its due responsibilities and cannot simply mention the goals and slogans of "marketization" or "industrialization". The essence of coordinating the harmonious development between man and nature is moderate population growth, sustainable utilization of resources and maintaining a good ecological environment. China is a country with less per capita resources, and resource constraint is a big problem accompanying the whole process of industrialization and modernization. The choice of industrialization and urbanization road, development mode, development strategy and technical policy, and even the choice of social lifestyle must consider resource constraints and environmental carrying capacity. From the obedience and worship of nature in ancient times to the large-scale conquest and destruction of nature since the industrial revolution, the emphasis on the harmony between man and nature has developed to the present, which is a sign of human progress. The essence of coordinating domestic development and opening to the outside world is to make better use of domestic and foreign resources and markets, and realize the economic revitalization of China smoothly. China's international economic status is undergoing fundamental changes. The external environment we are facing now is completely different from that in the early days of reform and opening up or even ten years ago. In the past, the system and policies formed under the conditions of closed economy, less import and export and shortage of foreign exchange need to be reformed, and many economic concepts need to be updated. At present, it is beneficial to appropriately increase the import of resource-intensive products and introduce more advanced technologies. In terms of foreign trade and economic relations, we are pursuing a "win-win" situation. The rise of any economic and trade power, trade friction is inevitable. You should look at this problem with a normal heart. Please sum it up yourself-it's really impossible. Let me sum up for you: Scientific Outlook on Development is a brand-new thinking concept guiding China's modernization. Its basic connotation is: first, all-round development; The second is coordinated and sustainable development. The essence of coordinating urban and rural development is to promote the transformation of urban-rural dual economic structure and regional coordinated development, and realize regional development. The essence of coordinating economic and social development is to achieve all-round social progress on the basis of economic development, enhance the well-being of all people and coordinate the harmonious development between man and nature. It is also the essence of moderate population growth, sustainable utilization of resources and maintaining a good ecological environment. The essence of coordinating domestic development and opening to the outside world is to make better use of domestic and foreign resources and markets, and realize the economic revitalization of China smoothly.
