Different industries have their own characteristics, development stages, positions in the industry chain, and core contradictions. Stabilizing key industries requires tailored policies and measures. We need to establish a dynamic adjustment mechanism for policies and timely calibrate policy directions. The Ministry of Industry and Information Technology has recently deployed key tasks for the second half of the year, with the top priority being to fully consolidate the foundation of the industrial economy and implement policies such as the new round of ten key industries to stabilize growth. Stabilizing key industries is a precise regulatory mindset, which involves grasping key variables in the industrial economy, shifting from "flood irrigation" to "precision drip irrigation", and achieving the maximum stable growth effect with minimal policy costs. This approach not only holds the bottom line of short-term growth, but also leaves enough space for long-term transformation. The key industries are the "big players" of the industrial economy, which directly determine the scale of growth. The added value of the top ten key industries, such as steel, automobiles, and electronics, accounts for about 70% of the above scale industries. Stabilizing these key industries stabilizes the basic foundation of the industrial economy. Data shows that in the first half of the year, key industries such as electrical machinery, automobiles, electronics, general equipment, chemicals, and non-ferrous metals grew rapidly, and their contribution to the growth of large-scale industries further increased. Among the 41 industrial categories in China, the electronic information manufacturing industry has maintained the first place in terms of revenue for 12 consecutive years. It can be seen that the production and operation status of key industries directly affects the increase or decrease of the total industrial economy, and is the most intuitive and crucial force for stabilizing growth. Key industries have strong industry correlation effects and are the benchmark of industry attention. The upstream and downstream industrial chains of key industries are vast and complex, with one ripple affecting the whole system, and related fluctuations can cause a domino effect chain reaction. Stable key industries can drive collaborative growth between upstream and downstream industries, forming a virtuous cycle; Enhance the confidence of business entities in the future and attract more capital inflows; Encourage enterprises to further increase investment in research and development, continuously launch innovative products, stimulate consumption, and promote the vigorous development of the entire industry and even the industrial economy. The key industries are still the forefront of industrial upgrading and cultivating new driving forces. Stabilizing key industries can accelerate the development and growth of new technologies and industries, injecting new quality productivity into the sustained growth of the industrial economy. The differences between key industries determine that they face different problems and challenges. Different industries have their own characteristics, development stages, positions in the industry chain, and core contradictions. For example, industries such as new energy vehicles and high-end equipment are in the growth stage, while traditional industries such as steel and chemicals have entered the mature stage. The petrochemical industry includes the upstream, midstream, and downstream of the industrial chain, and its stability is related to the safety of raw material supply; Light industry is closer to consumer terminals and more sensitive to changes in market demand. The electronic information manufacturing industry is significantly affected by global supply chain fluctuations, while the building materials industry is closely related to domestic infrastructure investment. If these differences are ignored and a one size fits all policy is implemented, it will only result in a mismatch of resources, which not only makes it difficult to achieve stable growth, but also brings more hidden dangers. Stabilizing key industries requires tailored policies and measures. For the automotive industry, implementing demand side stimulus policies such as reducing or exempting purchase taxes and accelerating the construction of charging infrastructure is more effective; For the steel industry, implementing policies such as upgrading environmental standards and replacing production capacity can force structural optimization and green transformation; For the electronic information manufacturing industry, policies such as trade in, stabilizing the supply chain, and expanding overseas markets have higher priority. It should also be noted that industry conflicts will evolve with changes in internal and external environments. It is necessary to establish a policy dynamic adjustment mechanism, maintain a keen perception of the industry through regular research, enterprise discussions, and other methods, and timely calibrate policy directions. Accurate policy implementation leads to long-term effectiveness. Previously, the Ministry of Industry and Information Technology launched a round of work plans to stabilize the growth of ten key industries, focusing on both supply and demand sides, fully unleashing the effects of these industries' large scale, wide correlation, and strong driving force. If the new round of policies accurately aligns with the transformation needs of the automotive industry, the green demands of the steel industry, and the innovation aspirations of the electronic information manufacturing industry, it will promote the sustained improvement of the industrial economy and lay a solid foundation for long-term development.
