Explains how firm resources can create sustained competitive advantage within strategic management research. Builds on assumptions that resources are heterogeneously distributed across firms and remain stable over time. Discusses four empirical indicators—value, rarity, imitability, and substitutability—and applies a resource-based model to evaluate multiple firm resources. Concludes with implications for other business disciplines and contrasts internal resource analysis with external industry-based approaches.

# Firm Resources and SustainedCompetitive Advantage Jay BarneyTexas A&M University Understanding 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. Understanding 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. Although both internal analyses of organizational strengths and weaknesses Discussions 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.

JAY BARNEY Figure One.The relationshipbetween traditional“strengths-weaknesses-opportunities-threats”analysis,the re-source based model,and models of industry attractiveness. and 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. To 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

FAQs

What is the focus of the article on sustained competitive advantage?

It examines how firm resources link to sustained competitive advantage in strategic management research.

Which four indicators are used to evaluate resources for sustained competitive advantage?

The article discusses value, rarity, imitability, and substitutability as empirical indicators.

How does the resource-based view differ from traditional environmental models?

It assumes firms may be heterogeneous in strategic resources and that those resources may not be perfectly mobile, making heterogeneity long lasting.
