Interpretation of Made in China 2025： Promoting the Development of Energy-saving and New Energy Vehicles
"Made in China 2025" puts forward "energy-saving and new-energy vehicles" as a key development field, and makes it clear that "we will continue to support the development of electric vehicles and fuel cell vehicles, master the core technologies of low-carbon, informationization and intelligence of automobiles, enhance the engineering and industrialization capabilities of core technologies such as power batteries, drive motors, efficient internal combustion engines, advanced transmissions, lightweight materials and intelligent control, form a complete industrial system and innovation system from key components to complete vehicles, and promote energy conservation and innovation of independent brands. The development strategy has pointed out the direction for the development of energy-saving and new energy automobile industry in China.
First, the automobile industry is an inevitable choice for the strategy of manufacturing a strong country.
From the perspective of manufacturing power, the automobile industry is listed as a national strategic competitive industry because of its important position in the national economy and its important contribution to economic growth. The second industrial revolution, represented by automobiles, lasted for more than a hundred years, and manufacturing powers such as Europe, America and Japan were all automobile powers. At present, with the third industrial revolution as the background, global technological innovation and economic recovery are increasingly active, and the automobile industry is the most comprehensive and large-scale carrier and platform for technological innovation such as digitalization, networking, intelligence, new energy, new materials and new equipment involved in the third industrial revolution, so it has once again become a representative industry of industrial revolution and industrialization level.
Whether it is driven by innovation or the sustainable and healthy development of the national economy, the automobile industry with large-scale effect and industrial correlation should be a strategic industry. The added value of China’s automobile industry accounts for only 1.53% of GDP, which is far from the 4% level of a powerful automobile country. The reason is that we are at the low end of the industrial chain, manufacturing rather than creating, so a stronger automobile industry will play a more important role in the development of the national economy. At the same time, the strong industrial correlation and driving force of the automobile industry is also a concentrated expression of the technological innovation level of China’s manufacturing industry.
Second, the main problems and constraints faced by the development of the automobile industry
(1) Lack of understanding of the important strategic position of the automobile industry in the construction of manufacturing power and economic transformation and upgrading, and lack of clear, systematic and sustainable industrial development strategy and top-level design. In recent years, China’s automobile industry has developed rapidly, but the development strategy of automobile industry is still unclear and lacks a systematic and complete strategy of automobile power. The unsustainability of the automobile industry policy leads to large fluctuations in the domestic automobile market, and the production capacity of enterprises is either difficult to adapt or idle, which intensifies the low-level competition in the domestic market and makes the industry big but not strong.
(2) The key core technologies are controlled by people, and the ability of independent innovation is weak. At present, China’s major automobile groups have not fully mastered key technologies in the fields of passenger car platform technology, engine system and new energy batteries, and have not yet formed a complete industrial system and capability.
(C) the lack of basic research common technology platform and innovation system support. At present, China has initially established an innovation system combining government and Industry-University-Research. However, due to many factors such as industrial organization structure, enterprise scale and governance model, the research on basic common technologies is still weak. In addition, there is no cross-industry, cross-field and cross-technology coordination management mechanism.
(D) The overall technical level and R&D capability of the traditional automobile industry are weak, and the supply chain system is incomplete, which restricts the rapid development of strategic emerging industries. Due to the relatively weak innovation ability and R&D investment intensity of traditional automobiles and related industries in China, the related industrial chain is not perfect, and some key parts and raw materials and key components depend on foreign countries, which restricts the rapid development of energy-saving and new energy vehicles.
(5) The development of soft environment such as business operation mode and humanities is lagging behind, and it still takes time to cultivate independent brands. At present, the business model dominated by the automobile industry is still uncertain, and the construction of automobile cultural environment lags behind. At the same time, the technical level, product quality and performance of domestic automobiles still lag behind the international advanced level and lack core competitiveness.
Third, energy-saving and new energy vehicles are the only way for automobile manufacturing to become a strong country.
With the rapid growth of global car ownership, the pressure of energy, environment and safety is increasing. From the perspective of sustainable development, the automobile industry must solve the four public hazards of energy, pollution, safety and congestion recognized by the world. Low-carbon, information-based and intelligent vehicles have been considered as the ultimate solution.
Countries such as the United States, Japan and Europe have put forward the development goals of low carbon, electrification and intelligence of automobiles, and accelerated the transformation and transformation of the automobile industry under the background of the development of new generation information technology and clean energy technology by strengthening technological innovation and cross-industry synergy and integration.
In terms of low carbon, major automobile developed countries have basically put forward the goal that the fuel consumption of passenger cars will reach 5L/100km in 2020 and 4L/100km in 2025.
In terms of electrification, with the active promotion of governments and the efforts of major automobile manufacturers, based on the technical progress and cost reduction of power batteries, the process of global automobile electrification is accelerating. In 2014, the global sales of electric vehicles reached 300,000. According to the prediction of the International Energy Agency, by 2030, electric vehicles will account for 30% of the world’s automobile sales.
In the aspect of intelligence, advanced countries in the world have defined the blueprint of automobile industry as a digital model to realize the integration of design, manufacturing and service based on network. For example, German Industry 4.0 clearly defines the information and physical integration system of smart cars, facilities and manufacturing services based on the Internet, and defines the timetable for promoting the information and physical integration from automobile mechatronics to intelligent driving. In 2050, the European Union plans to form a traffic area with integrated intelligence and interconnected cars, and the connected cars will be listed in 2015.
In 2014, the sales volume of automobiles in China reached 24.39 million, and by the end of 2014, the number of automobiles was 145 million. In recent years, China’s dependence on oil imports is close to 60%, and oil consumption in the transportation sector accounts for nearly 50%, of which nearly 80% is consumed by automobiles. At the same time, the contradiction between urban road traffic has become increasingly prominent, and automobiles have become an important source of environmental pollution. Thus, the automobile industry shoulders the important responsibilities of improving traffic, protecting the environment and saving energy. It is urgent for China automobile industry to develop energy-saving and new-energy vehicles and realize low-carbon, electric and intelligent development. According to the current situation of China’s automobile industry, based on the existing foundation of the automobile industry, promoted by the national strategic emerging industries and energy conservation and emission reduction regulations, it is possible to form a low-carbon, information-based, intelligent energy-saving and new energy-saving automobile advantage field during the "Thirteenth Five-Year Plan" period.
