Path selection for social network evolution map formation of start-up enterprises

This paper reveals the internal relation between start-up enterprises´ social network evolution map formation and its path selection, puts forward such four hypotheses about path selection as risk preference difference hypothesis, step length average hypothesis, relative expected return hypothesis and path random switching hypothesis in the formation process of social network evolution map of start-up enterprises, constructs the path selection model, obtains the effects mechanism of path selection of different risk preference degree on the risk return of start-ups in social network evolution map formation.
