近年來，環保意識逐漸抬頭，環保相關法規使廠商必須納入綠色環保概念於產品製造供應鏈中，供應鏈廠商彼此間的知識分享行為及協同合作可能成為影響其績效的重要因素。本篇有別以往在綠色供應鏈議題上實務管理工具、資訊平台及綠色供應商評選之研究，以社會資本的觀點來探討綠色供應鏈的上游供應商及下游顧客廠商應如何去改善整體綠色供應鏈績效，並藉由社會資本的三大構面(結構構面、關係構面、認知構面)來分析在鑲嵌在綠色供應鏈中的社會資本何為使績效改善的主要因素。 本實證研究指出，本研究模型的測量模式具有良好的信效度，在結構模式方面則發現:(1)社會資本的結構構面與認知構面對知識分享為顯著正向影響；(2)社會資本的認知構面對於環境協同合作為顯著正向影響；(3)知識分享與環境協同合作對於綠色供應鏈績效皆為正向影響；(4)知識分享亦會透過環境協同合作來正向影響綠色供應鏈績效。 In recent years, the environmental awareness have raised up. Companies must comply with environmental protection regulations and take the environmental concept into the supply chain management. Hence, knowledge sharing and environmrantal collaboration between supply chain partnerers become the most important factor of performance improvement. Previous studties focused on practical managment tools and information platform for green supply chain management, and vendor evaluation. In this study, we explored social capital’s contribution to green sulppy chain performance, and utilized the three constructs of social capital (structual, relational, congnitive dimensions) to analyze which is the main factor to improve green supply chain performance. The empirical results of this study reveled that there is good reliability and validity in measurement model, and also showedin the results of structual model: (1) both structual and congnitive dimentions of social capital positively affect knowledge sharing；(2) congnitive dimention of social capital positively affects environmental collaboration；(3) both knowledge sharing and environmental collaborartion between the firm and its partners positively affect green supply chain performance；(4) knowledge sharing and green supply chain performance is moderated by environmental collaboration.
