Core Viewpoint - The 2025 China International Digital Economy Expo highlights the integration of digital technology and ecological development in Weichang, showcasing its unique approach to transforming local industries through digital empowerment [1][6]. Group 1: Digital Empowerment in Key Industries - Weichang focuses on four core industries: semiconductor new materials, traditional Chinese medicine digitization, full-chain data services for potatoes, and low-altitude economy [1][3]. - Hebei Toshi Crystal Armor Technology Co., Ltd. demonstrates an innovative path with "diamond semiconductor and green electricity," utilizing local green energy resources to optimize production processes for high-precision materials [3]. - Chengde Daze Agricultural Technology Co., Ltd. has developed a "shared cloud platform for traditional Chinese medicine," breaking down data barriers among stakeholders to create an intelligent operation system based on demand data [3]. - The Weichang Potato Research Institute's "Smart Potato Industry" initiative digitizes over 300 germplasm resources and implements standardized management using climate and soil data, optimizing processing and sales through data tracking [3]. Group 2: Low-altitude Economy Development - Hebei Xunjie Low-altitude Economy Co., Ltd. leverages Weichang's geographical advantages to create a closed-loop low-altitude economy ecosystem, focusing on general aviation operations, drone manufacturing, and integrated data services [4]. Group 3: Exhibition Impact and Future Prospects - The expo serves as a platform for showcasing Weichang's digital economy achievements and facilitates connections with the Beijing-Tianjin-Hebei region, enhancing the brand's recognition and industrial influence [6]. - Weichang's development strategy emphasizes the dual drive of ecology and digital technology, aiming to integrate digital infrastructure with ecological protection and rural revitalization [8].

Core Insights - The article provides a comprehensive overview of the superhard materials industry in China, detailing the production processes, applications, and regional distribution of companies involved in this sector [1][3][4]. Industry Overview - The superhard materials industry chain includes upstream raw material processing and chemical processing, leading to the production of diamond single crystals, which are then crushed into diamond powder for tools like saw blades and drill bits [1]. - The downstream applications of superhard materials are categorized into four main sectors: mineral oil services, precision manufacturing, high-tech industries, and jewelry [3]. Regional Distribution - The majority of superhard materials companies are concentrated in Henan province, followed by the Yangtze River Delta region, with fewer companies in Guangdong, Shaanxi, Beijing, and Shandong [4]. - The Henan cluster has the most companies and encompasses the most complete industry chain, focusing on industrial diamonds and cultivated diamonds, while the Yangtze River Delta is known for its technological research capabilities [8]. Industrial Parks - There are currently eight major superhard materials industrial parks in China, primarily located in Henan, Jiangsu, Guangdong, Shandong, and Inner Mongolia, with Henan having the highest concentration of three parks [9]. Company Capacity and Production - The superhard materials industry features a wide distribution across various segments, with upstream competition, a dense midstream, and a dispersed downstream market. Key companies and their production capacities include: - China Graphite: Approximately 1.23 million tons of natural graphite, accounting for about 76.9% of global production [13]. - Zhongbing Hongjian: The largest domestic producer of synthetic diamonds, with a production share of about 50% of the global total [13]. - Huanghe Xuanfeng: Approximately 2,000 six-sided top-press machines, with cultivated diamond revenue around 600 million yuan [13]. - Liliang Diamond: Industrial diamond production of 150.66 billion carats and cultivated diamond production of 2.772 million carats, expected to gradually reach capacity from 2024 to 2026 [13]. Investment Trends - Since 2020, representative companies in the superhard materials sector have shown various investment trends, reflecting strategic planning and competitive dynamics within the industry. For example: - Hengxing Technology has invested in expanding diamond wire production capacity to meet the needs of photovoltaic silicon wafer cutting [14]. - ST Xinye has gradually exited the superhard materials business, integrating into the national machine system [14]. - Sifangda has established a semiconductor division to enter the CVD cultivated diamond market, indicating a shift towards high-value applications [14].
