| Summary: |
本研究採用科技接受模式(Technology Acceptance Model, TAM)為理論分析基礎，分析近年政府所推出的太陽能購電補助政策底下，民眾裝置太陽能發電設備意願之因素分析。本研究以高雄地區一般消費大眾為研究對象，採問卷調查方式進行實證分析，總共發放300份問卷，回收有效問卷239份，有效問卷回收率為79.7％。此外，問卷資料經由敘述性統計分析、因素分析、信度分析、效度分析以及結構方程模式來論證實證結果。本研究參考以往相關研究，分別以六個構面：「系統品質」、「有用性認知」、「易用性認知」、「使用態度」、「政府補助」與「購買行為意向」，來探討民眾裝置太陽能發電設備意願。實證結果發現：民眾購買裝置行為意向受到「使用態度」的影響較大，而設備「使用態度」受到「有用性認知」的影響較大，而「有用性認知」受到「系統品質」的影響較大。綜上所述，如何確保太陽能發電系統發電量的穩定性、20年耐用年限品質保證及系統安裝之安全性是目前民眾較關注的項目(即「系統品質」)；另外提升個人環保形象與創造環保節能的居住環境會提高民眾對選購太陽能發電系統的安裝意願(即「使用態度」)；民眾不知如何選購適合自家使用的住宅型太陽能發電系統與認為評估過程是不容易的，顯示目前太陽能發電系統的通路與購買產品的便利還不夠普及(即「易用性認知」)。當政府補助金額愈高(即「政府補助」)，使用太陽能發電系統之態度對購買意向影響不顯著，因此太陽光電業者在推廣太陽能發電系統時，可朝太陽能發電系統品質這方面與及太陽能發電系統的通路、購買便利多做努力，以增進民眾瞭解太陽能發電系統所帶來的效益。讓台灣成為一座太陽光電示範島嶼。 Based on the theory of Technology Acceptance Model (TAM), this study analyzes how the government-sponsored program of solar energy subsidy in recent years has an effect on people’s willingness to install the solar energy facility. This study adopts the investigation of questionnaires, and participants are consumers in the Kaohsiung area. There are totally 300 questionnaires distributed, among which 239 were completely filled and returned, resulting in a response rate of 79.7%. After sampling, we use a series of analytic tools that include descriptive statistical analysis, reliability analysis, validity analysis, factor analysis, and structural equation modeling to test and validate our hypotheses.Following previous researches, this study discusses people’s acceptance toward the solar energy facility in terms of six different factors: “system quality,” “perceived usefulness,” “perceived ease of use,” “using attitude,” “government subsidy,” “consumer’s behavioral intention.” In our findings, a consumer’s behavioral intention is largely guided by his or her “using attitude,” this “using attitude” is then guided by the “perceived usefulness,” and the “perceived usefulness” by the “system quality.”Accordingly, what really matters for people nowadays is the factor of “system quality,” which involves an assurance of the stability of the system, the safety and affordability of the installment, and 20-year quality insurance. In encouraging positive “using attitudes,” our government should promote the value of individual eco-images and work to create an ecological and electricity-saving living environment. A good policy is not necessarily self-explanatory. People are skeptical about the use and safety evaluation of solar energy; or they simply don’t know how to choose a compatible solar power installment for their home. All of these show that the policy of using solar energy is premature and that we are not yet ready for “purchasing” this idea in Taiwan.Although “government’s subsidy” seems ineffective in our study, the solar energy policy as a whole proves prosperous and influential. Suppliers and producers of solar energy should work harder on the improvement of the “system quality,” “ease of use,” and accessibility and affordability of solar energy facilities. An enlargement of people’s knowledge about solar energy can boost purchase rates. More significantly, it allows Taiwan to emerge as a paradigm of the solar-powered island. |
