What is the relationship between niche and performance? We identify two types of niche positions-product niche and process niche-defined by the extent to which a firm offers distinctive products and has distinctive operational processes, respectively. We argue that the effect of each niche on firm performance is contingent upon network embeddedness-the extent to which a firm is involved in a network of interconnected inter-firm relationships. Using data covering the period 1995-98 pertaining to venture capital firms and their holdings in initial public offerings (IPOs), we show that both product niche and process niche interact with network embeddedness to determine firm performance. Our findings suggest that the extent to which a firm offers distinctive products or processes will be more positively associated with firm performance when network embeddedness is high. CopyrightA key to understanding inter-firm competition is the concept of niche. A niche represents a firm's distinctiveness relative to other players in the competitive arena. As such, a niche describes not only a firm's competitive environment, but also how it competes with others (Carroll, 1985). A niche allows a firm to establish differences by offering a product or set of products that few, if any, other firms offer (Porter, 1980;Stuart, 1998), or by doing business using operational processes that few, if any, other firms practice (Baum and Oliver, 1996;Carroll, 1984Carroll, , 1985.1 Firms in a niche Keywords: network embeddedness; product niche; process niche; venture capital * Correspondence to: Ann Echols, Smeal College of Business Administration, Pennsylvania State University, 403 Business Administration Building, University Park, PA 16801, U.S.A.

The concept of niche has attracted considerable interest in management research. Population ecologists have examined properties of a firm's niche (Hannan and Freeman, 1977;McPherson, 1983) and the impact of a niche position on competitive dynamics. For example, in a study of the worldwide semiconductor industry, Podolny, Stuart, and Hannan (1996) have shown that niche-firms have enhanced firm survival rates. Strategic management scholars have also identified the niche position as a way of competing in the marketplace. For example, in studying strategic groups, Harrigan (1985) investigated the heterogeneity of strategic positions among firms and emphasized the value of holding a distinctive position in an industry. Drawing extensively from industrial organization economics, Porter (1980Porter ( , 1996 has analyzed competitive positioning of firms and argued that niche-firms can justify charging higher pr...
