目標：本研究旨在探討台灣民眾對奈米產品與科技的公眾感知，並分析影響其利益、風險與信任的社會人口學變項與決定因子。方法：本研究於2007年8至9月，委託中央研究院調查訪問中心，以電話抽樣完成1,251例18歲以上民眾的橫斷性調查訪問。研究樣本具性別代表性，但是年輕與年老族群的代表性比較不足。結果：在全部受訪者中，有81.3%聽過奈米產品，女性、年輕，以及教育程度較高，聽過的比例較高。決定高利益感知的主要變項是男性、年齡介於50至59歲間、教育程度大專以上、低風險，以及高信任；決定高風險感知的主要變項，是年齡四十歲以上、低利益，以及低信任；而決定高信任感知的變項，則是低教育程度、高利益與低風險。結論：本研究發現台灣成年民眾對奈米產品有很高的熟悉度，除了性別、年齡與教育程度之外，對奈米科技的管制信任，是影響其利益及風險感知的重要因素。

Objectives: To explore the public perception of nano-products and nanotechnology in Taiwan, and to analyze the demographic factors and determinants associated with the perception of risks and benefits. Methods: A cross-sectional telephone survey was conducted by the Center
for Survey Research, Academia Sinica from August to September 2007, with a randomized sample of 1,251 adults aged 18 and older. The sample was representative in its distribution by gender,but not by age. Results: A total of 81.3% of participants had heard of nano-products, especially
among female, younger, and more highly educated groups. General linear model analysis indicated that male, older age, higher education, lower risk, and higher trust were the determinants of perception of higher benefits of nanotechnology. Older age, lower benefit, and lower trust were
the determinants of higher risk, and lower education, higher benefit and lower risk were the determinants of higher trust. Conclusions: A high percentage of Taiwanese adults have heard of nano-products. Other than gender, age, and education, trust played an important role in determining their perceptions of the risks and benefits of nanotechnology.
