Abstract: Dividing customer participation under crowdsourcing mode into two key dimensions of customer participation under collaborative crowdsourcing mode and competitive crowdsourcing mode, determining out two important dimensions of interpersonal interaction and man-machine interaction of customer interaction, the paper establishes the mechanism model of the driving of customer participation under crowdsourcing mode on new product value creation by mediating effects of customer interaction. Empirical test results sampling as customers show that full mediating effect of interpersonal interaction on the relationship of the driving of customer participation under collaborative crowdsourcing mode on new product value creation is statistically significant, but it has no mediating effect on the relationship of the driving of customer participation under competitive crowdsourcing mode on new product value creation. Man-machine interaction has partial mediating effect on the relationship of the driving of customer participation under competitive crowdsourcing mode on new product value creation, but there is no mediating effect on the relationship of the driving of customer participation under collaborative crowdsourcing mode on new product value creation.
