近年來因為電信相關技術發展快速，再加上自 1995 年開始我國政府開放了電信公司化，電信公司彼此間的市場競爭越來越大，消費者的選擇變得也更為寬廣;2020 年我國新制定了電信管理法，以取代舊有的電信法。因應新制電信管理法允許電信公司採取共頻共網方式營運，而共頻共網可以帶給消費者更好 的使用者體驗，消費者在此情況下有無可能轉換所使用電信公司，就其對電信公司的忠誠度進行相關因素的探討，評估相關的影響因素為本研究的主要目的。

在模型假設下，本研究發現企業形象對消費者忠誠度有影響，在共頻共網新制下，消費者對於企業形象的認知，會影響其對於使用電信公司的忠誠度，電信公司在未來銷售策略上，應更為建立起屬於各自企業形象的特色;本研究發現價格對消費者忠誠度有影響，在共頻共網下，消費者對於價格的認知，會影響其對於使用電信公司的忠誠度，電信公司在未來的銷售策略上，應更為重視如何設計出讓消費者願意接受的資費方案，透過有競爭力的價格留著既有消費者並且吸引潛在的消費者;本研究發現服務品質對消費者忠誠度有影響。在共頻共網新制下，消費者對於服務品質的認知，會影響其對於使用電信公司的忠誠度，電信公司在未來銷售策略上，應更為提升服務項目的品質。

本研究總結了包含企業形象、價格、服務品質三種構面對於消費者忠誠度的影響程度，再藉由本研究了解不同構面的影響程度，並了解支持假說的緣故，對於消費者的偏好抉擇能擁有更好的認識，且能提供電信公司在未來營運上，如何留住既有和吸引更多潛在消費者，進而擴大增加其市場的佔有率。

In 2020, Telecommunications Management Act was newly formulated to replace the outdated Telecommunications Act. In response to the new Telecommunications Management Act, telecommunications companies are allowed to operate in spectrum sharing and internet sharing. Spectrum sharing and internet sharing can bring customers a better user experience. Under this circumstance, will consumers change their telecommunications company they use? Customer loyalty to telecommunications companies is discussed, and the main purpose of this research is to evaluate influencing factors including brand image, price, service quality.

The data of the study was collected with the questionnaire through an effective sample of 394 users from the Internet. Structural Equation Modeling (SEM) was used to analyze user’s choices. In addition, empirical evidence was based on the model fit from the results of Cronbach's Alpha, factor analysis, chi-square goodness-of-fit, and regression analysis.

The results show the brand image (p<0.001), price (p=0.002), and service quality (p<0.001) were all significant to customer loyalty under the new Act. It shows that telecommunications companies should put more emphasis on their brand image and service quality. Moreover, they should offer competitive prices to consumers. This study can have a better understanding of consumers' preferences and can provide telecommunications companies with better sales strategies in future operations.
