What is the significance of developing circular economy?

Circular economy is in the people, natural resources and science and technology system, in the resource input, enterprise production, product consumption and waste of the whole process, the traditional reliance on resource consumption of linear growth of the economy, to rely on ecological resource cycle to the development of the economy. The concept of circular economy is an economic growth model in line with the concept of sustainable development, and is a fundamental change to the traditional economic growth model of "mass production, mass consumption and mass disposal". The circular economy model can make more effective use of resources and protect the environment, and obtain the greatest possible economic and social benefits with the smallest possible consumption of resources and environmental costs, so as to make the economic system and the material circulation process of the natural ecosystem in harmony with each other, and to promote the sustainable use of resources. As a brand-new way of economic growth, circular economy is a concrete embodiment of the scientific concept of development and an inevitable choice for realizing the scientific concept of development. The development of circular economy is of great significance, mainly reflected in the following aspects: First, the development of circular economy is the best choice to alleviate the current contradiction of resource constraints. Although the total amount of resources in China is large, but the per capita possession of resources is far below the world average level, the possession of mineral resources is less than half of the world average level; per capita possession of energy level is even lower, crude oil is the world average level of 8.6%%, natural gas is the world average level of 5%%. The supply of domestic resources is insufficient, and the dependence of important resources on foreign countries is rising. Some major mineral resources are becoming more and more difficult to extract, the cost of extraction has increased, and the supply situation is quite severe. Since the reform and opening up, we used the doubling of energy consumption to support the quadrupling of G D P; by 2020, to realize the quadrupling of G D P, even if the doubling of energy considerations, to ensure that the supply of energy is also a great deal of difficulty. If we continue to follow the traditional development model of industrialization and modernization through massive consumption of resources, it will be unsustainable. In order to reduce the pressure of economic growth on the supply of resources, it is necessary to vigorously develop a circular economy and realize the efficient use of resources and recycling. Second, the development of circular economy is an effective way to radically reduce environmental pollution. At present, China's ecological environment is deteriorating, the atmospheric environment is not optimistic, solid waste pollution is becoming more and more prominent, the low rate of harmless treatment of urban living garbage, rural environmental problems. A large number of facts show that a large number of water, air, solid waste pollution, and the level of resource utilization is closely related to the crude economic growth mode is intrinsically linked. According to estimates, China's energy utilization rate if we can reach the world's advanced level, can reduce sulfur dioxide emissions of about 4 million tons per year; solid waste utilization rate if we raise 1 percentage point, can reduce the emission of about 10 million tons of waste each year; fly ash utilization rate if we can raise 20 percentage points, can reduce emissions of nearly 40 million tons, which will make the environmental quality has been greatly improved. Vigorously develop the circular economy, the implementation of cleaner production, economic and social activities on the demand for natural resources and the ecological environment to minimize the impact, and fundamentally solve the contradiction between economic development and environmental protection. Third, the development of circular economy is an important measure to improve economic efficiency. At present, China's resource utilization efficiency is still low compared with the international advanced level, which is highlighted by: low resource output rate, low resource utilization efficiency, low level of comprehensive utilization of resources, low recycling and recovery of renewable resources and recycling rate. For example, according to the current exchange rate, in 2003, China's G D P about 4%% of the world, but the important resource consumption of the world's share is very high, oil for 7.4%%, 31%% of the raw coal, iron and steel 27%%%, cement 40%%. Even if some incomparable factors are excluded, there is still a big gap between China's resource utilization rate and the world's advanced level. Practice has proved that the lower level of resource utilization has become an important obstacle for enterprises to reduce production costs, improve economic efficiency and competitiveness; vigorously develop circular economy, improve resource utilization and enhance international competitiveness has become an important and urgent task facing us. Fourth, the development of circular economy is the objective requirement of economic globalization and environmental globalization. With the development of globalization and the increasingly close relationship between trade and environment, environmental factors have become an important obstacle to free trade affecting developing countries. Due to the overall low level of environmental protection in China's economy, we will face more and more environmental pressure in the field of foreign trade. Some industrial products and agricultural products are susceptible to the restriction of green trade barriers in developed countries due to the low environmental protection requirements in the links of production, packaging, and use; with the development of trade liberalization, the invasion of polluting industries, hazardous substances, and exotic species will pose a threat to China's national environmental security. Enhance China's environmental competitiveness, to achieve the coordinated development of China's trade and environment, requires the development of circular economy. Fifth, the development of circular economy is an important guarantee for the comprehensive construction of moderately prosperous society. To build a moderately prosperous society in an all-round way, it is necessary to realize not only material, political and spiritual civilization, but also ecological civilization. The report of the 16th National Congress puts forward: "To build a moderately prosperous society in an all-round way, it is necessary to make the capacity of sustainable development continuously strengthened, the ecological environment improved, the efficiency of resource utilization significantly improved, the harmony between human and nature promoted, and the whole society promoted to embark on the civilized development path of production development, affluent life and ecological well-being." The history of industrialization in developed countries and the development history of China's economic construction show that if China continues to take the traditional road of industrialization with high input, high consumption, high pollution and low efficiency, not only the goal of building a moderately affluent society in an all-round way of ecological civilization can not be achieved, but also due to the constraints of the resource and environmental basis of economic construction, it is also difficult to achieve the goal of material civilization. As a mode of economic development in harmony with the environment, the circular economy can meet the requirements of the new road of industrialization and sustainable development, and realize the "*** win" of economic development, social progress and environmental protection, which is an important guarantee for building a moderately prosperous society in an all-round way. In short, the development of circular economy is conducive to the formation of resource-saving, environmentally friendly mode of production and consumption patterns, is conducive to improving the quality and efficiency of economic growth, is conducive to the construction of resource-saving society, and is conducive to the promotion of the harmonious development of human beings and the natural world, fully embodies the essential requirements of the concept of comprehensive, coordinated and sustainable development, is to achieve the overall construction of moderately affluent society is an important safeguard of the ambitious goal, but also the relationship between the fundamental long-term development of the Chinese nation. It is an important guarantee for the realization of the ambitious goal of building a moderately prosperous society in an all-round way, and a fundamental plan for the long-term development of the Chinese nation. We must recognize from a strategic height, with a global vision to grasp the importance and urgency of the development of circular economy, and further enhance the development of circular economy consciousness and sense of responsibility.
