In recent years, China's export cross-border e-commerce has emerged as a new force, and multiple professional cross-border e-commerce platforms have helped "Made in China" achieve transformation, upgrading, and going global by delving into the national industrial belt. Industry experts believe that "industrial belt+cross-border e-commerce+digital flexible supply chain" can not only help industries expand international business opportunities overseas, but also help many domestic industries upgrade through digital flexible supply chain, achieve "small order quick response" and on-demand supply, effectively improve the competitiveness and development level of "Made in China" in the global market. The reporter learned that there are currently hundreds of distinctive industrial belts in China, distributed throughout the country. In recent years, more and more industrial belt enterprises have utilized cross-border e-commerce channels to seize opportunities to go overseas and achieve significant development in product innovation, brand building, global business layout, and other aspects. Through cooperation with the industrial belt, cross-border e-commerce platforms can further expand merchant resources, increase the richness of product supply, and create advantageous categories. The professional cross-border e-commerce platform SHEIN recently announced the launch of the National 500 City Industrial Belt Overseas Plan. Within three years, it will delve into the national 500 City Industrial Belt, assist more high-quality manufacturers and brands to go overseas, and drive more industrial upgrades. By connecting the industrial belt with digital trade and digital flexible supply chains, we will not only help cross-border e-commerce expand overseas and expand sales and brand enhancement in the global market, but also help more industrial chains achieve digital upgrading and on-demand supply. In the clothing industry, the overseas children's clothing market size reached 140 billion US dollars in 2022, benefiting from the continuous deepening of online consumption habits of overseas users, the penetration rate of e-commerce in the overseas market continues to increase, and the international market space for online children's clothing is huge. The person in charge of relevant enterprises told reporters that with the continuous deepening of the application of platform models and the provision of flexible and diverse options for independent operation and agency operation to go overseas based on the needs of sellers, the platform will assist more sellers and industries to open up a broad international market through one-stop empowerment, promote brand strength improvement, and achieve industry digitization and flexible upgrading. In addition, professional cross-border e-commerce platforms such as Alibaba AliExpress and Amazon Global Store are also vying to increase their layout and support for the industrial belt. Industry insiders believe that the industrial belt concentrates China's high-quality supply chain, and from the perspective of scale, classification, and infrastructure, many industrial belts have the potential and advantages to develop cross-border e-commerce. The "cross-border e-commerce+industrial belt" model is a powerful combination of new business formats and high-quality supply chains. It is understood that creating a new export model "small order quick response" refers to the platform using actual market demand to predict sales and control production. Under the premise of real-time analysis and tracking of fashion trends, all SKUs (minimum inventory units) are started from very small orders, with each SKU generally starting from 100 to 200 pieces. If the sales trend is good, orders are immediately increased, and if sales do not meet expectations, production is suspended. By real-time understanding of market trends and consumer feedback through the front-end, the platform can make more accurate predictions of the market, thereby formulating subsequent product line styles, positioning, and planning. After entering the production process, the production and quality management requirements and standards for each style will be digitized online
