近年來，從社會網絡的觀點來研究經濟行為廣受不同學科學者的注意。在眾多的研究脈絡中，又以對市場的研究最受學者的矚目。此一研究脈絡將市場視為一特殊的社會結構，企圖去理解重複、規律的交換關係結構如何影響經濟個體的行為。本研究奠基於美國學者 Burt 所提出的結構自主模型（structural autonomy model）及傳播效應模型（network contagion model），探討產業間的交易網絡結構對市場績效的影響。本研究運用主計處所編製的產業關聯表及民國八十年工商業普查原始資料，來分析臺灣的126個產業部門之間的交易關係。研究發現一個產業的績效，與其在整個交易體系中所處的結構性地位有關，且處於相同地位的產業，其績效較為一致。

　　　　　During the past few decades, researchers from various disciplines have successfully adopted a network perspective to the study of economic behaviors. Among various research streams, the study of markets as a specific kind of social structure received by far the most attentions from network researchers. Central to this line of inquiry is the conceptualization of markets as recurrent and patterned exchanges between economic agents. This study builds upon prior works done by Ronald S. Burt by applying two specific network models--structural autonomy model and network contagion model--to the study of transactional relationship among 126 industry sectors. The purpose of the study is to examine the impact of pattern of exchange relations within an economic system in determining various market outcomes. Based on the 1991 census data of more than 700,000 establishments in Taiwan and the input-output tables compiled by the Directorate-General of Budget, Accounting and Statistics, this study shows that market performance is positively related to an industry's degree of strcutural autonomy. Furthermore, a stronger contagion effect is found among structural equivalent sectors than among cohesive sectors.
