台灣自產能源缺乏需仰賴進口，是屬於能源價格接受者，易受國際能源價格波動影響。在燃料煤方面，台灣進口燃料煤成本費用十分龐大，而且燃料煤為國內發電燃料之重要能源，在發電結構中屬於基載，因此如何降低燃料煤採購成本並維持穩定供電，係一重要且值得研究之議題。
本研究主要目的是分析影響燃料煤價格之因素。過去探討燃料煤價格相關文獻中，以數量分析或聚焦於單一層面的文獻居多，而本研究嘗試利用質性的方法論 — 紮根理論研究法，進行三階段編碼，蒐集約40篇相關文獻和書籍，分析歸納其中的影響因素，並分成基本面和市場實務面進行探討。
最後，將分析歸納出的影響因素進行彙整，建構出亞太市場燃料煤價格之影響因素機制圖，以及運用此機制圖之步驟，從中分析影響燃料煤價格變動之重要關鍵因素，可供燃料煤採購時之參考。
研究結果顯示，運用紮根理論建構出亞太市場燃料煤價格之影響因素機制圖，其篩選後之重要關鍵因素為：(1)常規：季節性因素及日澳長約因素；(2)短期：供需大國市場影響力、替代能源價格…等，(3)長期：供需國政策性因素、國際整體經濟情勢…等。

Because of the shortness of indigenous energy resources and the reliance on imported energy, Taiwan is not only an energy price taker but also easily influenced by international energy price fluctuation. Besides, the cost of steam coal is very expensive. Steam coal is an important part of Taiwanese power generation and be used as base load plant. Therefore, it is essential to study how to reduce procurement cost of stem coal and maintain supply of power steadily.
The main purpose of this study is to analyze the factors which affect stem coal price. In the past, most researches on this issue would use quantitative analysis or focus on single aspect. However, in this study we attempt to use qualitative analysis - Grounded Theory to execute three phase coding. This study searches about 40 references and books. Then, constructing the figure of setting mechanism for steam coal price by relevant literature and analyzing the key factor which affects steam coal price.
According to the results of this study by using Grounded Theory, we find the key factors are (1)General factors：season factor and the signing time of long-term contracts in Japan and Australia.(2)Short-term factors：market influence of high supply and demand country, the price of substitute energy…and so on (3)Long-term factors：the policy of supply and demand country, economic trend in all countries…and so on.
