The Southern Taiwan Science Park generated revenue of NT$2.3 trillion ($71 billion) in 2025, nearly double the NT$1.3 trillion recorded by the historic Hsinchu Science Park, according to official data that underscores how Taiwan Semiconductor Manufacturing Company's expansion is fundamentally reordering the island's economic geography.
The reversal is striking. For decades, Hsinchu—located in northern Taiwan near Taipei—served as the undisputed center of the island's technology industry. TSMC's original fabs, along with facilities operated by United Microelectronics Corporation and other chip firms, made Hsinchu synonymous with Taiwan's semiconductor dominance.
Now that status is shifting southward to Tainan and Kaohsiung, driven by TSMC's need for resources that northern Taiwan cannot provide: land, water, and electricity.
"The numbers tell the story," observed one industry analyst in a discussion on the Taiwan Reddit community. "TSMC operates more fabs in the south than in Hsinchu, and its facilities are extremely land, water, and electricity intensive, which gives the land-abundant southern region a significant advantage."
The Southern Taiwan Science Park, which spans areas in Tainan and Kaohsiung, has nearly twice the land area of Hsinchu Science Park and continues expanding. Most of TSMC's planned fabrication plants are concentrated in the south, including facilities for 3-nanometer and 2-nanometer process technologies that represent the cutting edge of global semiconductor manufacturing.
The shift reflects simple physics. Modern chip fabs require extraordinary amounts of ultrapure water—a single facility can consume as much water as a city of 50,000 people. They also demand stable, massive electrical supplies; TSMC's most advanced fabs each require as much power as 100,000 households.
Southern Taiwan, with access to reservoirs, desalination capacity, and proximity to power generation facilities, offers advantages that densely developed northern regions cannot match. The Tainan city government has made attracting TSMC investment a core policy priority, streamlining permits and coordinating infrastructure.
The economic consequences extend beyond manufacturing. TSMC's southern expansion has driven population growth in Tainan, reversing decades of migration to Taipei. Housing prices in areas near the science parks have more than doubled since 2020. New shopping districts, international schools, and cultural facilities have emerged to serve the influx of engineers and their families.
"Is the economic center of gravity shifting south?" asked the original poster of the Reddit discussion that highlighted the revenue figures. The data suggests the answer is increasingly yes—at least for the semiconductor industry that generates roughly 15 percent of Taiwan's GDP.
The Central Taiwan Science Park, located in Taichung, posted revenue of NT$911 billion in 2025, with year-on-year growth of 10.22 percent. The Southern Taiwan Science Park saw growth of 39.55 percent, compared to just 6.66 percent for Hsinchu.
Yet the shift should not be overstated. Hsinchu remains home to TSMC's research and development headquarters, where next-generation process technologies are developed before transfer to volume production facilities in the south. The park also hosts the highest concentration of semiconductor equipment suppliers and materials companies in Taiwan.
"Hsinchu is the brain; the south is the muscle," one semiconductor engineer commented in the Reddit thread. The distinction captures the emerging division of labor, with Hsinchu focused on innovation and the south on large-scale manufacturing.
From a strategic perspective, TSMC's geographic diversification serves another purpose: resilience. Taiwan faces constant concerns about natural disasters, water shortages, and—less discussed publicly but omnipresent—the risk of conflict with China. Distributing manufacturing capacity across multiple sites reduces vulnerability.
The expansion also reflects competitive pressure. TSMC faces intensifying competition from Samsung in South Korea and from subsidized domestic production in the United States and Europe. Maintaining technological leadership requires continuous capital investment—TSMC's 2026 capital expenditure budget exceeds $40 billion, much of it directed toward southern facilities.
Taiwan's government has supported the shift through infrastructure investment, including high-speed rail expansion, water pipeline construction, and power grid upgrades. The moves represent implicit acknowledgment that TSMC's decisions shape national economic development.
"Watch what they do, not what they say." TSMC's actions—where it builds, how it allocates capital—reveal its assessment of Taiwan's economic future more clearly than any corporate statement or government policy paper.
The southern expansion does create risks. Concentrating so much advanced manufacturing capacity in a relatively small geographic area increases vulnerability to disruption, whether from earthquakes, typhoons, or other events. The 2021 water shortage, which hit southern Taiwan particularly hard, demonstrated the fragility of assuming unlimited resource availability.
For now, the trend appears set to continue. TSMC's pipeline of planned projects shows the majority of new capacity additions in the south through 2028, ensuring that the Southern Taiwan Science Park's lead over Hsinchu will likely widen in the years ahead.
