Small and medium-sized enterprises, with their small scale and active mechanisms, often specialize in specific fields and play an indispensable and unique role in promoting innovation. The modern economic system is an organic whole, which requires both towering trees like large enterprises and numerous small and medium-sized enterprises competing with each other; At the recently held 19th China International Small and Medium Enterprises Expo, the interaction between the audience and humanoid robots was quite smooth, requiring both an "elephant army" and an "ant army". "Can we take a photo with you?" and "Please introduce yourself. Although some R&D companies may not be large in scale, the robots they develop can be applied to various scenarios such as flexible intelligent manufacturing and experimental testing, and their capabilities are not small. The new technologies and products showcased at the expo showcase the efforts of small and medium-sized enterprises to move towards novelty. General Secretary Xi Jinping attaches great importance to the development of small and medium-sized enterprises, clearly stating that "China's small and medium-sized enterprises have vitality and energy, are good at facing difficulties and striving for self-improvement", and emphasizing that "small and medium-sized enterprises can accomplish great things". In October, the production index of small and medium-sized enterprises in China was 50.7%, which remained in the expansion range for six consecutive months; The export index of small and medium-sized enterprises is 51.9%, which has been in a prosperous range for seven consecutive months. The overall stable expansion of small and medium-sized enterprises has laid a solid foundation for China's stable economic growth, structural adjustment, and strong confidence. Compared to large enterprises, small and medium-sized enterprises have smaller scales and more dynamic mechanisms, often delving deep into niche fields and playing an indispensable and unique role in promoting innovation. In the CNC equipment industry cluster of Wanjiang Street, Dongguan, Guangdong, a precision technology company has been rooted here for more than ten years, growing from a small and micro enterprise to a leading enterprise in the industry, with product customers covering well-known domestic and foreign enterprises. This is a microcosm of specialized and innovative small and medium-sized enterprises striving for excellence in specific fields. Fill in the gaps, break monopolies, and reserve future technologies... Countless small and medium-sized enterprises choose to dig "one foot wide" and "ten thousand meters deep", deepening, penetrating, and rising in segmented fields, shining and heating up at every node of the industrial chain, forming an overall momentum for industrial transformation and upgrading. Employment is the foundation of people's livelihood, which is not only related to the happy life of thousands of households, but also to the overall economic development. Small and medium-sized enterprises have a large number, wide distribution, and deep reach, which are the driving force and important "reservoir" for absorbing employment. Small and medium-sized enterprises contribute to the majority of urban employment opportunities in China. On this basis, some new trends have also attracted attention, with more and more small and medium-sized enterprises developing towards specialization, refinement, and innovation, attracting a large number of highly specialized college graduates and skilled talents; A large number of small and medium-sized enterprises related to the Internet platform have also become important employment channels, giving birth to new employment patterns and modes. Better leveraging the role of small and medium-sized enterprises as a "reservoir" for employment will continuously expand employment capacity and improve employment quality. Small and medium-sized enterprises are like the capillaries and nerve endings of an economic organism, helping to smooth the economic cycle and form an ecological system and network effect for economic development. Faced with the uncertainty of the international market, Jinjiang, Fujian has created an industrial ecology with complete chains, complete supporting facilities, and complete elements through strengthening and supplementing chains, and continuously optimized this ecology. Taking the sports shoe industry as an example, within a radius of 50 kilometers, all elements covering the entire chain of research and development, production, and sales can be found. The interdependent and complementary network effects of small and medium-sized enterprises can be transformed into resilience in the industrial chain to withstand various uncertainties. The modern economic system is an organic whole, which requires both towering trees like large enterprises and numerous small and medium-sized enterprises competing with each other; We need both an "elephant army" and a "ant army". How to further increase support and service efforts to promote the development and growth of small and medium-sized enterprises? Some good practices that have emerged are worth learning from. For example, in order to solve the problem of financing difficulties for small and medium-sized enterprises, many places have launched intellectual property pledge financing reforms, allowing small and medium-sized enterprises that lack sufficient collateral assets but have intellectual property value to obtain financing, and promoting the transformation of "intellectual property" into "assets". For example, digital transformation is not only a measure to help enterprises overcome difficulties, but also a key to enhancing their competitiveness. Guangdong is exploring a new model from single point breakthrough to "chain transformation", organizing 120 leading and platform enterprises to lead and drive 800000 small and medium-sized enterprises to "go cloud and use cloud". For example, in the face of insufficient orders, some places help more small and medium-sized enterprises integrate into the industrial chain and supply chain of large enterprises, and encourage "chain owners" to share orders with upstream and downstream small and medium-sized enterprises. Some small and medium-sized enterprises are trying the "live streaming+e-commerce" overseas model to promote their efficient entry into the overseas e-commerce market. Small and medium-sized enterprises are stable, with stable development expectations; Only when small and medium-sized enterprises are good can the Chinese economy thrive. Countless small and medium-sized enterprises are like stars, together forming the brilliant galaxy of China's economy. By leveraging the driving role of large enterprises, stimulating the vitality of small and medium-sized enterprises, and forming an industrial ecology that integrates the development of large, medium, and small enterprises, we can continuously enhance the resilience and momentum of China's economic development, injecting strong impetus into promoting long-term sustainable and healthy economic development.
