近年來全球暖化、極端氣候等現象日趨嚴重，促使國際間對於節能永續發展的議題愈益重視。基於當前電能供給與國家經濟發展及民生需求息息相關，更因臺灣適逢用戶端之電力網路的基礎設備持續老化，無形中也造成電力的額外損失。爰此，先進國家積極開源節流，研擬具體節約措施與管理對策。有鑑於各國電能管理的近程發展，多提出節能控制儀器智慧電表，希冀經由自動化耗能監測機制，採擷使用者的用電態樣，藉以優化用電趨勢，改善能源營運績效。臺灣目前正處智慧電網初期部署階段，住宅用電尚未普及安裝智慧電表。因此，探討居家空間智慧電表的採用傾向與推行策略，是當前之課題所在。本文首先從文獻回顧分析，歸納瞭解使用者實際採用的考量因子，進而用以評估一般住宅用戶在現代化科技應用的接受程度。資料收集採問卷填答方式，隨機方便抽樣訪談，量化使用者對智慧電表的預期接受程度。分析方法則係應用結構方程模式，驗證評估指標對於構面值的解釋能力。其次，藉由分析結果推求消費者採用意願指數作為現況基值，並從指標重要性與使用者感受程度二維分析，辨識影響採用傾向的重要因素，反饋規劃後續推行策略的實證依據。文末則從量化分析結果配合受訪者的有效填答建議，探討質性意涵。研究發現可釐清使用者主要的考量面向暨其因果關連，用以整體評估安裝使用意願，並做為日後能源相關管理單位從社會人文層面，於科技行銷推廣的持續性策略評估與強化重點，促成永續節能發展的目標。

Global warming and extreme weather have been increasingly severe in recent years, prompting countries worldwide to pay attention to energy conservation and sustainable development. Power supply is closely related to the economic development and daily needs of the people in a country. However, in Taiwan, the infrastructure of electrical grids in the consumer end is deteriorating, which intangibly results in additional electricity losses. Thus, numerous developed countries have actively developed alternative energy sources and formulated measures and management strategies to reduce energy consumption. In the recent development of power management, numerous countries have proposed using smart meters for energy-conservation control. Specifically, they intend to use an automatic energy consumption monitoring system to record the electricity consumption pattern of consumers, thereby optimizing an electricity consumption trend and improving the efficiency of energy usage. Taiwan is currently at the initial stage of smart grid deployment. Smart meters have not been widely installed to monitor residential electricity consumption; therefore, investigating the adoption propensity and implementation strategies of smart meters in residential buildings is a critical research topic at present. This study began with a literature review to identify the factors considered by users in their actual adoption of smart meters and subsequently assessed general residential consumers’ acceptance degree of contemporary technologies. Structured questionnaires were used to interview a randomly selected sample to quantify users’ expected acceptance degree to the use of smart meters. Structural equation modeling was employed to verify the explanatory power between assessment criteria and dimensions. Based on the analysis result, the consumer adoption propensity index was employed as the baseline for the current consumers’

willingness to use smart meters. A two-dimensional analysis based on index importance and perceptions of potential users was conducted to identify the crucial index that influenced the adoption propensity. The indicatiors served as the feedback for the basis of subsequent implementation strategies. Implications were discussed qualitatively at the end of this paper. The analytical findings clarify the primary factors considered by consumers and can be used to assess the intention of people to install smart meters. Therefore, energy management authorities can adopt a social and humanistic perspective to continually enhance strategies for technology marketing, thereby achieving the goals of energy conservation and sustainable
development.
