本研究主要目的有二：第一乃從社會網絡觀點探討外派人員其派任地與母公司兩地個人社會網絡結構對其取得資訊、資源及人脈資本之程度，進而對其職涯晉升之影響；其二，除個人互動網絡外另從外派人員知覺組織(母公司)支持程度對其在派任地與母公司兩地社會網絡特徵之影響。
透過問卷調查方法取得台灣跨國企業派任海外人員共267份有效樣本。利用驗證性因素分析，進行構念聚合效度、區別效度及信度分析。並以結構方程式模型驗證研究假設。研究發現：一、外派人員於派任地的個人社會網絡對其在取得資訊、資源及累積人脈資本上有正向影響；而外派人員在母公司的社會網絡亦在取得資訊、資源上有正向影響。二、外派人員其取得資訊、資源及累積人脈資本的程度與個人職涯晉升間有正向關係。三、外派人員知覺組織支持程度與個人在派任地與母公司兩地之社會網絡皆有正向關係。
本研究主要貢獻在於：過去研究針對外派人員社會網絡影響皆僅從派駐國的角度探討。而本研究證實從外派人員的跨邊界角色來看，即便暫離母公司派駐至另一海外據點，外派人員不僅於派任地建立新的社會網絡外；同時維持與母公司個人網絡連結對其在資訊、資源取得及人脈資本上確有正向影響。此外從個人無疆界職涯的觀點來看，此同時考量外派人員派任地與母公司的社會網絡的整合架構，當可提供後續在外派人員與其社會資本形成與職涯發展議題上進一步研究基礎。

The objectives of this dissertation are to examine how expatriates’ social network affect the ability of access information/resource and knowing- whom capital on their career advancement, as well as the effects of perceived organizational support correlate to host and home social network. Specially, this research investigates dual sources (host and home office) of expatriates’ network in order to understand the impact on the network abilities and extent.

Through confirmed factor analysis of pretest data, measurements were refined and the questionnaire used for the study was developed. For the study, 267 surveys were used for the data analyses. Structural equation modeling in LISREL 8.8 was employed to analyze the relationships among the latent constructs. The findings from the study revealed significant relationships between 1) expatriates’ social network of host office and access information & resource, 2) social network of host office and knowing whom capital, 3) expatriates’ social network of home office and access information & resource, 4) access information & resource and career advancement, and knowing whom capital and career advancement.
This study contribute theoretically to the expatriates dual social network literature by clarifying the relationships among host social network, home social network, social network abilities and career advancement, while the previous studies focus on expatriates host country context. This research findings pointed out the expatriates not re-establish a personal network in the host environment but still keep contact with his/her home social network. The expatriates’ host social network has direct and strong effect on access to information/resources and knowing-whom capital. And the expatriates’ home social network also has positive impact on access to information/resources. This empirical model also provides future research with a new angle of view over expatriates social network and career advancement.
