Industry Life Cycle


The Industry Life Cycle refers to the evolution of an industry over time, from its inception to its eventual decline. It is a financial theory that typically encompasses four stages: introduction, growth, maturity, and decline. Each stage has distinctive characteristics such as growth rates, profitability, competition levels and overall market saturation.


The phonetic spelling of “Industry Life Cycle” would be:Industry: /ˈɪndəstri/Life Cycle: /laɪf ˈsaɪkəl/

Key Takeaways

1. Phases: The Industry Life Cycle represents different stages of an industry over time. These phases typically include introduction/start-up, growth, maturity, and decline. In the start-up stage, innovation is driving growth, and there may be low levels of competition. During the growth stage, more competition enters the market with rapid sales growth. The maturity phase generally denotes slower growth and increased competition. In the decline phase, the industry starts to shrink as product demand decreases.

2. Strategic Implications: The stage of the industry life cycle impacts the strategies companies may adopt. For instance, during the introduction and growth stages, firms often invest heavily in research and development as well as marketing to establish their presence. In the maturity stage, companies might focus more on operational efficiency and market share protection. When in the decline stage, some organizations may exit the market or reinvent their products or services.

3. Impact on Investment: The industry life cycle stage may impact investment decisions. Investors might seek new and growing industries for potentially higher returns despite the higher risks, while they might approach mature industries for more consistent returns. Similarly, declining industries might be viewed as high risk unless they show signs of possible rejuvenation.


The Industry Life Cycle is a crucial business/finance concept as it provides significant insights into the evolution of an industry over time. It delineates the stages that an industry typically goes through, namely introduction, growth, maturity, and decline. Understanding this life cycle helps investors, entrepreneurs, and businesses make strategic decisions regarding market entry, investments, resource allocation, and competitive tactics. It helps identify the phase the industry is in, therefore providing clues about potential opportunities or threats. For instance, during the growth phase, there might be higher potential for revenue and profit growth, while the decline phase might entail increased competition or reduced demand. Thus, the Industry Life Cycle is an important concept in framing business strategies and decision-making processes.


The purpose of an Industry Life Cycle is to give a higher bird’s eye view of the different evolutionary stages that a typical industry goes through over time, and to help companies make strategic decisions attuned to their current industry phase. This concept is used to understand and analyze the different phases in the life of an industry, essentially beginning when the industry first serves a customer need and ends at its eventual decline or transformation. Companies employ this model to predict industry-related trends, identify threats and opportunities, assess competition levels, and comprehend transformational triggers.An Industry Life Cycle is primarily used by investors and managers as a part of strategic analysis to understand the state of an industry. This knowledge allows a company not only to position itself favorably against competitors but also to plan for long-term growth or withdrawal strategies. For investors, it aids in making informed decisions about investing or divesting based on the current stage of the industry. Overall, the Industry Life Cycle is a useful tool that serves to evaluate industry conditions, competition structure, and strategic trajectory, among others.


1. The Film Photography Industry – The film photography industry initially was in the growth phase and then matured rapidly with market giants like Kodak and Fujifilm. The industry faced its decline phase when new, digital photography technology was introduced in the market. With smartphones further enhancing their camera capabilities, the downturn of the traditional film photography industry has been even more pronounced.2. The Smartphone Industry – The smartphone industry is a perfect example of the growth phase in the industry life cycle. After the introduction of the first iPhone in 2007, multiple companies jumped into the fray, leading to rapid expansion and constant innovation. Now, it could be argued that the industry is in the maturity stage, as the pace of innovation has slowed down somewhat, and market shares have consolidated around a few key players.3. The Electric Vehicle Industry – The EV industry is currently in its introductory phase. Companies like Tesla, Nissan, and Chevrolet are slowly trying to capture market share and developing technology. Although the industry is growing, it is doing so in an environment where the traditional, gasoline-powered auto industry is mature and beginning to decline, thanks in part to the rise of the electric vehicles.Remember that the cycle stage can vary per region and is often subjective to interpret.
