Abstract: On the crowdfunding platform, various modes of community participation subvert the traditional modes of resource acquisition, which allows the process of resource acquisition to present the traits of many participation bodies, breaking traditional organizational boundaries and community. Based on the special background, the paper combines cognitive evaluation theory and social capital theory to analyze the impact of the motivation of individual participation on resource acquisition of new ventures. It also analyzes how interaction of communities impacts the resource inquisition of new ventures through affecting the social capital of communities from the angle of social capital. Finally, it describs the cross-level mechanism of the motivation of individual participation and community interaction in new ventures' resource inquisition, assuring the boundary conditions of main effect mechanism.
