The Shark model is a theoretical framework for the analysis and optimization of industrial structure, which is mainly used to study the behavior of enterprises in resource allocation, market competition and strategic decision-making. By treating market participants as different types of "sharks", the model reveals their interactions and adaptation mechanisms in complex environments.

In the shark model, participants in various roles are metaphorically represented as different species of sharks. Certain large sharks represent the dominant players in the market, and they often have strong financial strength and strong market influence to dominate the rules and standards of the entire industry. Small sharks, on the other hand, represent emerging or developing-stage businesses struggling to find their niche in the market, trying to compete for market share through innovation and flexibility. Therefore, the shark model emphasizes the diversity and dynamics of market competition, as well as the interaction between firms of different sizes.

The importance of the Shark model is that it can help companies understand their position in the market and their relationship with other companies. By analyzing the behavior of different sharks, enterprises can develop more effective competitive strategies. For example, large enterprises can expand their market share by acquiring small enterprises to ensure that they remain the leader in the fierce market competition. Small companies, on the other hand, can challenge the monopoly position of large companies by focusing on market segments or offering differentiated products.

In addition, the shark model provides a reference for policy makers. Understanding the interaction between various types of enterprises in the market can help them formulate more reasonable industrial policies, promote fair competition, and encourage innovation. This will not only help the overall economy.
