Competitive position effects and market share: An exploratory investigation

Abstract

This paper investigates the relative competitive position of a firm with a view toward determining those marketing effort dimensions that significantly influence market share. The study differs from previously published reports in that it utilizes the Profit Impact of Marketing Strategy (PIMS) data base on relative marketing effort to identify key marketing effort variables for two broad classes of goods: consumer nondurables and capital goods. The framework for a competitive positive effects model is developed in terms of nine relative marketing effort dimensions expressed along categories roughly corresponding to competitive superiority, parity, or inferiority. Hypotheses for the two classes of goods, gleaned from the available marketing literature, were empirically tested with use of linear regression models. Though the sets of coefficients relating to the nine marketing decision variables significantly differed ac across industries, similar patterns were found in both groups with respect to the relative breadth of product line and relative product quality dimensions. The results also tended to (a) support the claim of Buzzel et al. [Product Quality, Strategic Planning Institute, Cambridge, 1978] that for product quality to matter, improvements relative to competition must be substantial, and (b) show that for certain effort dimensions striving for competitive superiority may not generate sizable increases in relative market share.
