Which relevant consideration is not included in identifying an industry's economic features?

The identification of an industry's economic features primarily revolves around the elements that directly influence the industry's profitability and competitive dynamics. When considering what constitutes these economic features, concepts such as market size, economies of scale, and buyer bargaining power are crucial.

Market size and geographic competition provide insights into the overall demand for products within an industry and the competitive landscape, which can directly impact the strategies that firms adopt. Economies of scale are fundamental to understanding cost leadership and operational efficiency; they indicate how a firm's cost structure changes with production volume. Buyer bargaining power assesses how much influence customers have over pricing and terms, which is important for analyzing competitive pressures within the industry.

Conversely, the presence of strategic groups, while it does relate to competitive dynamics, does not fall under the specific umbrella of economic features. Strategic groups are defined as a set of firms within an industry that pursue similar strategies or have similar characteristics, distinguishing them from other groups in the competitive landscape. This concept focuses more on the strategies and positioning of firms rather than strictly on economic elements such as costs, trade volumes, or pricing power.

Therefore, the correct answer highlights that the presence of strategic groups, while significant in understanding competition and strategy formulation, does not directly qualify as an economic feature in the primary analysis
