Firm Resources and SustainedCompetitive Advantage\n\nJay BarneyTexas A&M University  \nUnderstanding sources of sustained competitive advantage has be-come a major area of research in strategic management.Building onthe assumptions that strategic resources are heterogeneously distrib-uted acrossfirms and that these differences are stable over time,this ar-ticle examines the link between firm resources and sustained competi-tive advantage.Four empirical indicators of the potential of firmresources to generate sustained competitive advantage—value,rare-ness,imitability,and substitutability—are discussed.The model is ap-pliedby analyzing the potential ofseveralfirm resourcesfor generatingsustained competitive advantages.The article concludes by examiningimplications of this firm resource model of sustained competitive ad-vantage for other business disciplines.  \nUnderstanding sources of sustained competitive advantage for firms has be-come a major area of research in the field of strategic management(Porter,1985;Rumelt,1984).Since the 1960's,a single organizing framework has been used tostructure much of this research(Andrews,1971;Ansoff,1965;Hofer &Schendel,1978).This framework,summarized in Figure One,suggests that firms obtain sus-tained competitive advantages by implementing strategies that exploit their inter-nal strengths,through responding to environmental opportunities,while neutral-izing external threats and avoiding internal weaknesses.Most research on sourcesof sustained competitive advantage has focused either on isolating a firm's oppor-tunities and threats(Porter,1980,1985),describing its strengths and weaknesses(Hofer &Schendel,1978;Penrose,1958;Stinchcombe,1965),or analyzing howthese are matched to choose strategies.  \nAlthough both internal analyses of organizational strengths and weaknesses  \nDiscussions with members of the Strategic Management Group at Texas A&M University,including MikeHitt,Tom Turk,Bob Hoskisson,Barry Baysinger,and Abby McWilliams,have been helpful in the developmentof these ideas.The rudiments of the argument were presented and discussed at the second annual WhartonCon-ference on Models of Strategic Choice.Discussions with Raphael Amit,Birger Wernerfelt,Michael Porter,David Teece,Dick Rumelt,Margie Petroff,Connie Helfat,Sid Winter,and Garth Saloner have had a significantimpact on the ideas developed here Iwould especially like to thank Cynthia Montgomery for convincing me towrite this article.  \nAddress all correspondence to Jay B.Barney,Department

traditional“strengths-weaknesses-opportunities-threats”analysis,the re-source based model,and models of industry attractiveness.  \nand external analyses of opportunities and threats have received some attention inthe literature,recent work has tended to focus primarily on analyzing a firm's op-portunities and threats in its competitive environment (Lamb,1984).As exempli-fied by research by Porter and his colleagues(Caves &Porter,1977;Porter,1980,1985)this work has attempted to describe the environmental conditions that favorhigh levels of firm performance.Porter's(1980)“five forces model,\"for example,describes the attributes of an attractive industry and thus suggests that opportu-nities willbe greater,and threats less,in these kinds of industries.  \nTo help focus the analysis of the impact of a firm's environment on its compet-itive position,much of this type of strategic research has placed little emphasis onthe impact of idiosyncratic firm attributes on a firm's competitive position(Porter,1990).Implicitly,this work has adopted two simplifying assumptions.First,theseenvironmental models of competitive advantage have assumed that firms withinan industry(or firms within a strategic group)are identical in terms of the strate-gically relevant resources they control an","cbCaibgTACZvZQuU","https://ap.wps.com/l/cbCaibgTACZvZQuU","pdf",1551540,22,"English","#
