Suzhou AI’s “Four Little Dragons” are on fire! Their stock prices have surged by as much as 10 times. Tianfu Communication, Dongshan Precision, Huidian Shares, and Hengtong Optoelectronics have all grown into trillion-yuan giants, and the “strongest prefecture-level city” is expected to become the sixth city with a GDP of 3 trillion yuan.

Ask AI · Why can Suzhou’s AI industry ecosystem lead the nation and support GDP growth?

As the dawn of the Middle East situation appears, global capital markets begin to recover, with the US, Europe, and Asia-Pacific markets rebounding collectively, and the A-shares and Hong Kong markets also bottoming out and rising.

Recently, the optical module sector has performed exceptionally well. “Yi Zhongtian” has returned, and currently, New Easy-Sense’s market value exceeds 450 billion yuan, Zhongji Xuchuang’s market value surpasses 650 billion yuan, and Tiansu Communication reaches 250 billion yuan. The combined value of these three is nearly 1.4 trillion yuan.

Among them, Tiansu Communication rose 11% yesterday, performing like an elephant dancing. Over the past year, Tiansu Communication’s lowest price was 39.94 yuan, and the highest reached 388.94 yuan, nearly a tenfold increase in stock price, and its market value has entered the “trillion-yuan club.”

As a result, Tiansu Communication has become the “strongest city in the universe” and the most valuable listed company in Suzhou. Besides Tiansu Communication, Suzhou’s Dongshan Precision, Huidian Shares, and Hengtong Optoelectronics have also successfully crossed the trillion-yuan mark, earning the nickname “Suzhou AI’s Four Little Dragons.”

Dongshan Precision’s stock price has increased from around 20 yuan to a peak of 120 yuan in nearly a year; Huidian Shares from about 25 yuan to 94 yuan; Hengtong Optoelectronics from approximately 15 yuan to 55 yuan.

It is worth noting that Tiansu Communication, Dongshan Precision, Huidian Shares, and Hengtong Optoelectronics are all stocks in the AI industry chain. Currently, Suzhou has formed a nationally leading, full-chain coverage, deeply empowered AI industry ecosystem. According to last year’s information released by Suzhou, from January to August 2025, Suzhou’s artificial intelligence industry achieved revenue of 247.2 billion yuan, with an 18.7% growth rate, establishing over 60 AI-related industrial platforms, and gathering nearly 2,500 upstream and downstream enterprises in the industry chain.

In 2024, Suzhou proposed to “use about three years to push GDP to the 3 trillion yuan mark.” By 2025, its GDP will reach 2.77 trillion yuan, significantly surpassing Chengdu, Hangzhou, and Wuhan, the three provincial capitals, seizing the initiative in the sixth city sprinting toward 3 trillion, with artificial intelligence as the core driver.

Returning to Suzhou’s AI “Four Little Dragons,” Tiansu Communication is the “water seller” in the AI computing power era. As a core component supplier for optical communication, its optical devices and optical engines are essential for the operation of computing clusters. It holds over 200 core patents, with high market share in high-end optical engines, deep technological barriers, aligned with industry development trends, and stable rigid demand orders. In March, the company stated on an interactive platform that its 1.6T optical engine products are being delivered normally, and related directions such as LPO and CPO will also be developed.

Dongshan Precision’s core logic focuses on the dual drive of AI computing power explosion and new energy. As a global leader in PCB and the second-largest FPC manufacturer worldwide, its high-end PCB products precisely meet AI server demands. Additionally, through acquiring SORC, it has expanded into optical module business, making it a core infrastructure provider for both PCB and optical modules in AI computing power. Meanwhile, Dongshan Precision has deeply partnered with major consumer electronics and new energy clients like Apple and Tesla. The recovery of consumer electronics and the increasing penetration of new energy vehicles bring incremental orders, further enhancing market expectations for its performance resilience.

Market speculation on Huidian Shares mainly revolves around the demand for high-end PCBs driven by AI computing infrastructure construction. Huidian Shares is deeply linked with leading tech companies like NVIDIA and is a key supplier of high-end PCBs for AI servers, high-speed network switches, and other core scenarios. It is viewed by the market as a “seller of shovels” in the AI computing power industry chain. Meanwhile, the prolonged overseas PCB expansion cycle has led to a continuous widening of supply-demand gaps, further reinforcing market expectations for Huidian Shares’ medium- and long-term growth potential.

Hengtong Optoelectronics’ core logic lies in its dual business model of “optical communication + ocean energy.” Amid the explosive growth in AI computing power demand, the demand for fiber optic cables and optical modules continues to rise. Hengtong benefits from high self-sufficiency in optical fibers and an integrated full-industry chain layout. Additionally, Hengtong has the capability to undertake global submarine cable projects, and with the offshore wind power boom, its submarine cable business also presents significant market potential.
