Also consulting British consular reports and other documents, she researched the impact of trade on Taiwan's economy and social structures in the 35 years from the signing of the Sino-British Treaty of Tianjin, which opened Taiwanese ports such as Tanshui, Keelung, Takou (today's Kaohsiung) and Anping (today's Tainan), up through the signing of the Treaty of Shimonoseki in 1895, when Taiwan was ceded to Japan.
佐以「英國領事報告」等其他檔案，她研究 1860 年《中英天津條約》簽訂生效、台灣開放淡水、基隆、打狗（今高雄）、安平（今台南）等通商口岸後，至 1895 年《馬關條約》台灣割讓給日本以前的 35 年間，進出口貿易對台灣經濟與社會結構的影響。
