苏州18年前投资的三千万，长成了AI的血管
- 核心观点：本文以中际旭创（原旭创科技）的成长历程为核心案例，阐述苏州如何通过系统性、长期主义的产业投资策略，在AI算力浪潮中抓住光模块这一关键供应链环节，从而驱动城市产业升级、资本增值与人才聚集，形成可持续的“飞轮效应”。
- 关键要素：
- 2008年金融危机期间，元禾控股向冷门领域的光模块初创公司旭创科技投资3000万元，这笔投资在18年后转化为市值超1.5万亿的A股巨头中际旭创，市值超越茅台。
- 苏州在AI产业中精准押注光通信产业链，除了中际旭创，还培育了天孚通信、源杰科技等企业，它们覆盖了从光芯片、器件到模块、测试的完整环节。
- 苏州的投资逻辑在于“蹲在地上选项目”：在早期通过科技招商中心、链主基金等机制，利用市场化手段和懂行的人才，对生物医药、纳米、语音AI等冷门赛道进行长期布局。
- 苏州的务实源于其工业基础薄弱的“穷出身”，通过“星期日工程师”、自费开发区等方式嵌入上海产业链，形成了扎实的工业积累和自担风险的创业精神。
- 当企业成长后，苏州4.89万亿的工业产值和完整门类为工业AI提供了天然的数据与应用场景，算力成为公共服务，反哺产业，形成了城市与企业双向赋能的正循环。

The most profitable investment in Suzhou occurred during the global financial crisis.
In the autumn of 2008, Lehman Brothers collapsed, and venture capital across China virtually ground to a halt. Investors were cutting losses and watching from the sidelines, as the primary market entered a deep freeze. It was in this window that Suzhou Industrial Park's state-owned venture capital platform, Oriza Holdings, invested approximately 30 million RMB in a startup.
The founder was Liu Sheng, a Tsinghua undergraduate and Georgia Tech Ph.D. who had spent many years in North America working in optical communications at Lucent Technologies and Opnext. In 2008, he returned from Silicon Valley, registered InnoLight Technology in Suzhou, aiming to produce high-speed optical transceivers.
In the 2008 investment landscape, optical transceivers were not just niche; hardly any investors were looking at this track. Domestic optical communication companies were all crammed into the telecom market and low-to-mid-end manufacturing. According to a LightCounting report, in 2010, only one Chinese company, WTD (later merged into Accelink Technologies), barely made it into the global top ten list. At that time, the judgment that "cloud computing data centers will require massive amounts of high-speed optical transceivers" was far from any consensus.
Eighteen years later, that investment grew into Zhongji Innolight. Just before the Dragon Boat Festival in June 2026, its stock price surged to 1367.88 yuan, giving it a total market capitalization of 1.5 trillion yuan, placing it in the A-share top ten, surpassing Kweichow Moutai.
The Blood Vessels of AI
Optical transceivers are crucial to the entire AI industry. Without them, AI is just a pile of heat-generating silicon chips. To transmit signals from chips through optical fibers between data centers, you need optical transceivers.
Computing power is the heart; optical transceivers are the blood vessels.
In the A-share market, Eoptolink, Zhongji Innolight, and TFC Communication are known as the "Yi Zhong Tian." These three optical transceiver giants have captured the most critical segment of the global AI computing power supply chain. Two of the three are based in Suzhou: Zhongji Innolight's Suzhou operations headquarters is in Suzhou Industrial Park, as is TFC Communication's operations headquarters.
Furthermore, Suzhou-based company Lianxun Instruments, which manufactures high-end optical communication testing equipment, saw its stock price surge over twenty times its issue price within two months of its IPO in 2026, claiming the title of A-share "stock king." Yanguji Technology, a leading active optical chip company and part of Zhongji Innolight's industrial chain investment, saw its stock price briefly touch 1712 yuan just before the Dragon Boat Festival, nearly quadrupling in six months.
Breaking down the AI data center, Suzhou's bet wasn't on a few isolated companies, but on a series of interconnected positions.
Further upstream are optical chip companies like Yanguji Technology; downstream is the optical device domain specialized in by TFC Communication. Zhongji Innolight packages these devices into high-speed optical transceivers and supplies them to global data centers. Lianxun Instruments is then responsible for testing whether these high-speed optical communication devices can run stably.
According to a report by Xinhua Daily, the total market capitalization of all A-share listed companies in Suzhou has exceeded 4 trillion yuan, ranking fourth nationwide, behind only Beijing, Shanghai, and Shenzhen.
Hangzhou's "Six Little Dragons" have been featured on Spring Festival Gala and trending topics. Shenzhen's humanoid robots are dancing. Three GPU companies in Shanghai are telling the grand story of domestic substitution. These stories are appealing, novel, and visual; a short 15-second video is enough to make a name stick.
But Suzhou tells a different kind of story.
An optical fiber manufacturer in Wujiang district saw its 2026 sales revenue grow over 35% year-on-year, with production capacity booked solid into 2027. Multiple companies in Suzhou's industrial chain jointly invested to start construction on the nation's first 8-inch silicon photonics chip mass production line. Suzhou's optical communication industry has formed a cluster worth hundreds of billions of yuan. Companies have taken the lead in establishing over 50 innovation consortia, and the industry's scale grew over 60% in the first quarter of 2026.
In this explosive growth of AI computing power, real money flowed first into the places that make the "blood vessels."
For Suzhou, once a leading optical transceiver company grows, it brings more than just market value. It brings along its suppliers, testing equipment makers, optical chip companies, funds, and talent. Its orders become capacity for upstream and downstream enterprises. Its listing becomes the creditworthiness of the local capital market. Its judgment on the industry, in turn, becomes clues for Suzhou's next round of investment promotion and strategic investment.
Beyond the paper investment returns, what Suzhou gained is an industrial chain that can continue to roll forward.
In 2024, the world suddenly discovered optical transceivers and rushed into the secondary market to grab chips, but Suzhou's name was already written on the earliest business registration documents of InnoLight – an old shareholder since 2008.
