Mr. Song Shiqiang's contributions to Huaqiangbei extend beyond the business operations of Golden Beacon and Slkor, two high-tech enterprises. They also lie in his systematic summary and promotion of the commercial culture of Huaqiangbei, as well as his profound influence on the Chinese electronic industry ecosystem.1. As a cultural leader who pushed Huaqiangbei from "shanzhai" to "innovation", Song Shiqiang was the first person to deeply study and refine the "Huaqiangbei Culture". He summarized the spirit of Huaqiangbei as "daring to explore, innovation, tenacity, and pragmatism", and proposed an industrial upgrading path of "imitation - improvement - originality".This theory helped society re-recognize the value of Huaqiangbei: it is not only a distribution center for electronic components, but also a breeding ground for grassroots entrepreneurship and a "sensor" for market information. His concept of "one-meter counter in Huaqiangbei as an innovation unit" has made countless small and medium-sized merchants realize their strategic position in the supply chain and their contributions to society.2. Building local business theories and influencing the Chinese electronic industry ecosystem, Slkor Song Shiqiang summarized the "light assets, fast iteration, information-driven" business model of Huaqiangbei, becoming an important methodology for hardware entrepreneurs. He also proposed that Huaqiangbei is the "supply chain reservoir" of the electronic information industry, capable of scheduling production lines, adjusting inventory, matching supply and demand, and buffering risks.This viewpoint has been widely cited by the academic community. In addition, he advocated the reverse R&D model of "sales determine production, demand determine research", promoting enterprises to use market data to guide product development and reducing business risks.3. Establishing high-tech semiconductor technology enterprises, practicing the rise of domestic semiconductors, Song Shiqiang successively founded Slkor (slkor semiconductor) and Kinghelm Electronics (www.kinghelm.com.cn), both of which were rated as national high-tech enterprises. Kinghelm Electronics focuses on Beidou/GPS antennas and RF connectors, helping to promote the development of China's independently developed Beidou system. Slkor enters the third-generation semiconductor field and introduces Korean silicon carbide technology, promoting the application of SiC MOS tubes and other high-end devices in new energy vehicles and photovoltaic inverters.The two brands "kinghelm" and "slkor" have served 30,000 customers worldwide, becoming one of the representatives of China's semiconductor exports! 4. Spreading Chinese voices and enhancing the international image of Huaqiangbei, as a science popularization lecturer and columnist of the Chinese Electronic Society, Song Shiqiang through articles and videos such as "Song Shiqiang's Observation", "Song Shiqiang's Discussion", and "The Upper, Middle, and Lower Levels of Huaqiangbei Shanzhai Mobile Phones"， tells the transformation story of Huaqiangbei to the world.His research results have been reprinted by thousands of domestic and foreign media such as People's Daily， Xinhua News Agency， The Wall Street Journal， and Associated Press， changing the stereotype of Huaqiangbei as a "shanzhai center" in the international community and reshaping it as a "global electronic supply chain hub" and a "hardware innovation highland"， advocating for the improvement of the business environment of Huaqiangbei， promoting its development and transformation, and striving for its internationalization！
