Concept is the precursor of action, and certain development practices are guided by certain development concepts. The 19th National Congress of the Communist Party of China (CPC) took adhering to the new development concept as the basic strategy for upholding and developing socialism with Chinese characteristics in the new era, expanded the connotation of development in an all-round way with the characteristics of the new era, and raised the ideas and theories on development to a new height. To implement the new development concept, we must first deeply understand and scientifically grasp its scientific connotation and practical requirements.

Innovation is the first driving force to lead development. The driving force of development determines the speed, efficiency and sustainability of development. For an economy of China's size, it is difficult to achieve high-quality economic development if the power problem is not solved well. Adhering to innovation and development is the conclusion drawn from the analysis of the world's development process since modern times, especially the conclusion drawn from summarizing the successful practice of China's reform and opening up, and is the fundamental policy to cope with the changes in the development environment, enhance the development momentum, grasp the initiative of development, and better lead the new normal. General Secretary Xi Jinping pointed out that if we grasp innovation, we will grasp the "bull's nose" that affects the overall economic and social development. To establish the concept of innovation and development, we must put innovation at the core of the overall development of the country, and constantly promote innovation in all aspects such as theoretical innovation, institutional innovation, scientific and technological innovation, and cultural innovation, so that innovation can run through all the work of the party and the state, and let innovation become a common practice in the whole society.

Coordination is an intrinsic requirement for sustainable and healthy development. The uncoordinated development of our country is a long-standing problem, which is prominently manifested in the relations between regions, urban and rural areas, economy and society, material and spiritual civilizations, and economic construction and national defense construction. Under the condition that the level of economic development is backward, the main task for a period of time is to run fast, but after running a certain distance, it is necessary to pay attention to adjusting relations and paying attention to the overall efficiency of development, otherwise the "barrel effect" will become more and more apparent, and a series of social contradictions will continue to deepen. To establish the concept of coordinated development, it is necessary to firmly grasp the overall layout of the cause of socialism with Chinese characteristics, correctly handle the major relationships in development, focus on promoting coordinated regional development, coordinated development of urban and rural areas, coordinated development of material and spiritual civilizations, promote the integrated development of economic construction and national defense construction, and continuously enhance the overall coordination of development.

Green is a necessary condition for sustainable development. Human beings are born from nature, and human beings and nature are in a symbiotic relationship, and human development activities must respect, conform to, and protect nature. At present, the situation of ecological and environmental protection in China is still very severe, and the people's demand for clean air, clean drinking water, safe food, and a beautiful environment is becoming more and more intense. To establish the concept of green development, we must adhere to the basic national policy of conserving resources and protecting the environment, adhere to sustainable development, firmly follow the path of civilized development with production development, affluent life and good ecology, accelerate the construction of a resource-saving and environment-friendly society, form a new pattern of harmonious development and modernization between man and nature, promote the construction of a beautiful China, and make new contributions to global ecological security.

Openness is the only way for a country to prosper and develop. Openness brings progress, while closure inevitably lags behind. Practice tells us that in order to develop and grow, we must take the initiative to conform to the trend of economic globalization and persist in opening up to the outside world. We should see that the international and domestic situations facing us are very different from those in the past, the situation of international economic cooperation and competition is undergoing profound changes, the global economic governance system and rules are facing major adjustments, the depth, breadth, and rhythm of bringing in and going out are incomparable in the past, and the pressure on coping with external economic risks and safeguarding national economic security is also incomparable with the past. To establish the concept of open development, it is necessary to improve the quality of opening up and the internal and external linkage of development, take the initiative to participate in and promote the process of economic globalization, develop a higher-level open economy, actively participate in global economic governance and the supply of public goods, improve China's institutional voice in global economic governance, and continuously strengthen China's economic strength and comprehensive national strength.

Sharing is the essential requirement of socialism with Chinese characteristics. "To govern the world, you must first be public, and if you are public, the world will be peaceful." Allowing the broad masses of the people to share the fruits of reform and development is the essential requirement of socialism, a concentrated embodiment of the superiority of the socialist system, and an important embodiment of our party's adherence to the fundamental purpose of serving the people wholeheartedly. When these problems are solved, the enthusiasm, initiative, and creativity of all the people in promoting development can be fully mobilized, and only then can the country's development have the most profound power. At present, the "cake" of China's development is constantly getting bigger, but the problem of unfair distribution is still quite prominent. In terms of sharing the fruits of reform and development, there are still imperfections in both the actual situation and the system design. To establish the concept of shared development, we must adhere to the principle that development is for the people, development depends on the people, and the fruits of development are shared by the people, make more effective institutional arrangements, and adhere to the principle of sharing by the whole people, all-round sharing, joint construction and sharing, and gradual sharing, so that all people can have a greater sense of gain, happiness and security, and make steady progress in the direction of common prosperity.

The concept of innovative, coordinated, green, open and shared development is interconnected and mutually reinforcing, and is an intrinsically related aggregate, which must be implemented in a unified manner, and cannot be ignored or replaced by each other. It is necessary to deepen understanding, grasp the new development concept from the whole and internal linkage, and constantly improve the ability and level of implementing the new development concept.
