新竹科學園區自1980 年成立，從業人口從最早規劃的2 萬多人發展至今已達13.4 萬人，車輛隨員工人數不斷成長，造成通勤時段大量汽機車擁入，形成長期塞車現象，主管機關雖透過調撥車道、巡迴巴士、增設交流道等方式解決，但成效並不顯著。本研究以政策工具與跨域治理理論為基礎，透過深度訪談法，訪談中央與地方政府機關人員、利害關係人及學者，探討各項政策工具的可行性與可能面臨的問題。本研究發現：對於竹科塞車問題，政府過去是以組織型工具為主，目前以財務型工具為主，資訊工具的應用則是政府正在規劃的工具類型。本研究進一步透過Hood 所提出的四種工具組合觀點，規劃出可以「減少路面汽機車」的方案，以提供政府政策規劃時的具體建議。

Hsinchu Science Park was established in 1980 with an estimation of employed population of over 20,000 people, which has now grown to 134,000 people. The number of vehicles passing this area rises along with the employed population and the traffic flow during rush hours is huge enough to cause a regular traffic jam in long term. The authority in concern has tried to solve the problem through different means such as reversible lane, shuttle bus, and additional interchanges, yet the improvement is not significant. This research is constructed on grounds of policy instruments and theory of across boundary governance and is conducted through a method of in-depth interview with officials of central and local governments, stakeholders, scholars studying transportation, attempting to investigate into feasibility and possible obstacles of different policy instruments. This research finds that the government used to take organizational policy instruments as the solution to the traffic problem in Hsinchu Science Park, but the incentive policy instruments is now mainly adopted and the application of information-based policy instruments is currently under development. Based on the perspective of Hood, this article suggests combination of four kinds of policy instruments, and proposes a solution to “reduce the vehicle flow” as a concrete suggestion in policy formulation.
