This invention belongs to the field of financial investment decision-making technology, specifically a financial investment decision-making assistance method and
system based on game theory and multi-source
big data. It collects and processes multi-source financial data, constructs a unified data foundation, and uses
machine learning to generate multi-dimensional
market prediction signals based on this foundation. These prediction signals are then input into a game
theory model to simulate the behavior of market participants, solve for equilibrium strategies, and generate investment or
risk control suggestions based on the game results, which are then visualized. This invention overcomes the limitations of single data sources by integrating multi-source
big data and generating multimodal prediction signals. By combining game theory to model the complex interactive behaviors of market participants, it can deduce market evolution trends from a global perspective, thereby assisting in the formulation of more forward-looking investment or
risk control strategies. It can simulate information
asymmetry, strategy interaction, and dynamic evolution processes in the market, thus providing a better understanding of market fluctuations and the
impact of sudden events.
