新竹科學園區用地已近飽和,行政院推動桃竹苗大矽谷計畫以擴展科技產業腹地。竹科三期開發案與國道3號二重交流道建設為解決園區擴張與交通壅塞之核心方案。
當全球半導體版圖持續往台灣集中,擁有竹科一期、二期、竹北生醫園區的新竹,科學園區用地幾乎滿載,為了讓AI與先進製程有地方繼續成長,科技軸線只能往東走,沉寂多年的「竹科三期」終於迎來關鍵轉折。
橫跨竹東頭重、二重、三重與柯子湖部分地區的「竹科三期」,範圍約454公頃,台灣高力國際業主代表服務部董事黃舒衛表示,新竹科學園區的用地幾乎已經滿載,「向東走,成了產業發展的必然解答。」
在行政院拍板「桃竹苗大矽谷計畫」、地方政府也積極推動下,規劃多年的竹科三期出現實質曙光,目前「依專案小組意見修正後,提請內政部都委會大會審議」。
新竹縣長楊文科表示:「竹科三期只要完成都市計畫程序,就能啟動都委會大會審議、都市計畫核定、區段徵收及後續開發程序。」新竹縣政府也說明,未來規劃導入優質產業聚落,預估可引進約2萬名就業人口,同步吸納2萬名居住人口。對竹東來說,竹科三期不只是腹地變大,更代表這裡正式被納入科技核心版圖。
過去竹東往返園區與外縣市,每到上下班尖峰,車潮常卡在竹林(芎林)和寶山兩座交流道之間。為了解決這個問題,也為了接住竹科三期未來湧入的大量人流,新竹縣加速推動「國道3號增設二重交流道」。
交通處說明,該項交通規劃截至2026年8月仍在「可行性研究」階段規劃,實際仍以中央核定為準,工程規劃採全立體化、無號誌化設計,取消主要聯絡道以減少車流交織風險,匝道直接銜接中興路,並預留未來延伸二重外環道、銜接台68線的空間,總經費約47億元。再加上已通車的東科路(高鐵橋下聯絡道三期)能直達園區力行路,以及台68線、公道五路橫向串聯,未來二重交流道會和周邊道路網連成完整的立體交通系統。除了公路,大新竹輕軌「棕線」也規劃串聯竹東、二重埔與竹科,讓這裡的對外通勤更方便。
交通一旦重新布局,最先反映在生活圈的變化與買方的目光上。目前關埔、竹北高鐵特區新案開價持續維持高檔。面對這樣的價格,年輕科技工程師家庭如果要自住,勢必得在價格與通勤距離之間找平衡點。二重埔緊鄰工研院與竹科,有中興路商圈、二重國小、二重國中等既有生活機能,目前二重埔新建案價格相對親民不少。
隨著科技用地與交通建設兩條線一起推進,二重埔正被重新定位為「科學園區東側門戶」。這裡緊鄰工研院與竹科三期預定範圍,加上台68線、園區聯絡道與周邊路網逐漸成形。生活機能上,二重國小、二重國中步行就能到,提供完整的九年一貫教育環境;日常採買也能靠中興路商圈,銜接新竹市光復路一帶,基本需求不用愁。
城市的發展,往往跟著產業與交通的腳步走。專家表示,30年前,竹科造就關新里的繁榮;10年前,高鐵改變了竹北的樣貌。如今,竹科三期啟動東擴引擎,國道3號二重交流道定錨了立體交通骨幹,竹東二重埔正從配角慢慢走向舞台中央。當二重交流道逐步成形、竹科三期的計畫輪廓愈來愈清楚,這塊過去被歸類為「竹科腹地」的土地,正站上從邊陲走向門戶的轉折點。

Statistics from the Ministry of the Interior show that the number of new homes for sale in Taiwan increased from 69,721 in the fourth quarter of 2021 to 112,501 in the fourth quarter of 2025, a five-year increase of 61.4%. The number of pending sales in Taoyuan and Kaohsiung has doubled, and the market has a strong wait-and-see sentiment. The gap between the speed of project promotion and digestion by builders has led to increased sales pressure. Experts point out that housing prices in some emerging areas may be under pressure, but mature business districts are still supportive.

The Tamsui Land Office launched the "Pre-sale House Sales Information Map" service, which integrates the actual price registration and basic construction project information of pre-sale houses in Tamsui and Bali districts. The public can use the map to check the distribution of construction projects, average transaction price, number of units, construction license number and other information, and to query the finalized contract, soil liquefaction potential and project progress in series, improving the transparency of real estate transactions and reference for home purchase decisions.

Buying momentum in the housing market has ebbed, the supply of new homes has increased, transaction volume has failed to keep up, and the pressure to sell out has increased. The national new housing transaction/use license ratio dropped from 58.8% in the first half of 2021 to 34.9% in the first half of 2026. The decline occurred in all six cities, indicating that the market's absorption of new housing has slowed down.

After the demolition of the Golden Empire Building in Yuanlin City, Changhua County, the county government promoted a public urban renewal project. The site area is about 1,530 square meters, and it is planned to introduce more than 2,000 square meters of shopping malls and public welfare facilities. On July 30, it officially announced the investment invitation, and a briefing session is expected to be held on September 21. More than 5 manufacturers have accepted bids, hoping to revitalize the business district in front of Yuanlin Railway Station.

Taichung's Beitun Chongde business district has attracted brand builders such as Kantons and Cathay Pacific due to its population growth and mature functions. Although the price of pre-sale houses has been slightly consolidating recently, the average price has still increased by 10.5% compared with 2013. The transaction price of new cases in the area has stabilized at 7 prefixes per square meter, and some cases have even exceeded 8 prefixes.

As electric vehicles become increasingly popular, home buyers’ requirements for housing have shifted from “whether there is a parking space” to “whether the parking space can be charged.” Experts point out that community power capacity, management committee regulations and consensus among residents are the key to determining whether charging piles can be installed. It is recommended that home buyers include charging infrastructure in their long-term residential assessment.
