本研究是利用代理人基模型 (Agent-Based model) 結合遺傳規劃法(genetic programming) 在模組化經濟體系下價格動態對市占率之影響。現今企業多數以市占率作為公司在市場上表現的主要指標，如果擁有高市占率的廠商，可以確定在這產業中生存。以往的文獻顯示模組化經濟下高價格廠商在市場上的表現會優於低價格廠商，取決重要因素為品質，因為高價產品通常品質也較高，容易取得消費者喜愛。本研究想探討是否在這個體系下，消費者所考量的都是以品質高低來決定是否購買產品，是否會有過去以往的價格競爭情形，以及在價格動態體系，市場所呈現的風貌如何。本研究設計39組的加成率參數組，並依據兩間廠商的決策上製作成價格動態矩陣圖表。試圖以這些已知參數組與線性內插法所預測之市占率的參數組進行分析。此研究模擬中發現，在模組化經濟下，價格競爭並不一定會讓市占率趨向於某一點均衡，也可能會趨向於一條路徑上。而且不一定是高價位的廠商會有很大機會獲得市場，也沒有所謂的贏家擁有超高市占率的情況產生。 / This study is the use of agent-based model combined with genetic programming to explore the impact of the price dynamics for the market share in the modular economy. Nowadays, the majority of enterprises use market share as the key performance indicators in the market, if the enterprise has a high market share, it can be determined to survive in this industry. The previous literature shows that manufacturers of high prices on the market under the modular economy will be better than the low-price manufacturers, depending on the important factors for quality. Expensive products are usually higher quality, easily favorite by consumers. My study is to investigate whether consumers consider in this system are based on the level of quality to decide to buy the product or not, and whether there will be price competitive situation, as well as the outlook presented by the market price dynamics system. In this paper, we design 39 markup rate’s parameter set and making price dynamic matrix diagram in accordance with the decisions of two manufacturers. Trying to analyze these known parameter set and the parameter set of the market share predicted by the linear interpolation. The simulation of the study found that in the modular economy price competition does not necessarily make the market share tends to a equilibrium point, or it may also tend to be a equilibrium path. But not necessarily high-priced manufacturers get to the market, there is no so-called winners with higher market share.
