本研究為了解企業總部成立後對跨國企業管理的影響。首先針對企業總部將如何改變母公司高階管理進行影響因素分析，歸納出現有管理方式與企業總部職能之關係。接著以個案研究的研究方法，針對所屬台灣網路線材產業的個案公司進行觀察及訪談，並進一步探究企業成立總部後對管理指標與營運流程的影響為何。最後分析其相互關係並以增進管理效率為目標，對個案公司管理方式提出改善建議。企業總部成立後對跨國企業產生之影響分別為以下三個部分:
首先是建立各事業部與子公司間之資訊整合與溝通管道、以集團目標統一人才管理系統、設立各事業部關鍵管理指標。其二為企業總部如何透過責任中心制設定，對事業部關鍵營運指標進行整合性管理。最後一部分為事業部營運單位需配合企業總部之成立擬定合適之控制策略以確保企業總部之管理效率，並得出研究結論為以下三個面向:
一、透過總部職能將使管理模式由事業部觀點提升至集團觀點，藉由其職能使集團管理效率提升。
二、企業總部將直接管理與事業部成功因素相關之績效指標以掌握事業部營運狀況。
三、企業總部功能將使作業層級以控制策略將管理制度一致化以確保各單位營運符合企業總部之目標。
最後針對個案公司提出管理改善與建議，並透過企業總部成立所會影響的管理要點。提供給其他欲成立企業總部之公司進行管理作為參考。

In order to understand the impact of corporate headquarters on multinational companies after the establishment of corporate headquarters, this study analyzes the factors that affect how corporate headquarters will change the parent company's senior management, and summarizes the relationship between management methods and corporate headquarters functions.
After the establishment of the company headquarters, the impact on multinational companies is divided into the following three parts:
First, establish the information system to integrate and communicate different business departments and subsidiaries, and unify the talent management system from a group perspective, and establish key management indicators for each business department. Secondly, how does the company headquarters establish comprehensive management of key business indicators of business departments through the responsibility center system? The last part is that the operation units of the business department needs to coordinate with the establishment of the company headquarters to formulate appropriate control strategies to ensure the management efficiency of the company headquarters.
The conclusion of the study is as follows:
1. Through the functions of the headquarters, the management model is upgraded from the perspective of the business department to the perspective of the team, and the efficiency of team management is improved through its functions.
2. The company headquarters will directly manage the performance indicators related to the success factors of the business department to grasp the business status of the business department.
3. The function of the corporate headquarters will enable the operation level to align the management system with a control strategy to ensure that the operations of each unit are in line with the objectives of the corporate headquarters.
