Method and system for analyzing social question and answer community knowledge propagation influence factors

The invention provides an analysis method and system for social question and answer community knowledge propagation influence factors. The method comprises the steps that an HK network model is initialized, and nodes give strategies in proportion; inputting variables representing social question and answer community knowledge propagation factors; gaming among the nodes is carried out, and accumulated knowledge income of each node is calculated; selecting a learning object for the nodes according to a profit priority principle, and updating a strategy through Fermi dynamics; judging whether the updated strategy reaches a preset time step or not: if not, turning to the step 2 until the preset time step is reached; and when a preset time step is reached, outputting an evolution result, analyzing the effect of variables representing different influence factors in reality on social question and answer community strategy evolution according to the result, and analyzing behavior rules and strategy selection of parti
