Power and firm profitability in supply chains: french manufacturing industry in 1993
研究了供应链中供应商和买方的权力如何影响中间企业的盈利能力，发现买方权力比供应商权力更能解释盈利差异，且行业效应比企业效应更重要。
The paper examines the relationships between the power of suppliers and buyers and the profitability of sellers who are situated in supply chains between both sets of firms. A review of the literature on power in exchange relations shows there are several power concepts which may have a different impact on seller profitability and whose impact possibly can offset each other. This may be the source of the conflicting evidence on this topic. A failure to distinguish among the concepts may also lead to an underestimation of industry effects relative to resource effects as drivers of firm profitability. The paper uses a new data base of the Banque de France on French manufacturing industry. The anlayses examine whether different power concepts may be empirically identified and what their relationships are with seller profitability. The findings point to the existence of multiple power concepts and indicate that, in the sample, industry effects are more important than firm effects (as measured by relative market share) in explaining seller profitability. The findings also suggest that buyer power explains a much larger percentage of the variance in seller profitability than supplier power. © 1998 John Wiley & Sons, Ltd.
