摘要:
This paper investigates how social network structure influences online medical crowdfunding performance. Using administrative data from a leading medical crowdfunding platform in China, we exploit detailed records of campaign information diffusion through social media to construct novel measures characterizing network structures. We find that campaigns achieving broader network penetration—characterized by lower concentration of views from the fundraiser's immediate connections—raise significantly more funds. This relationship operates through transcending homophily constraints, a mechanism we formalize in a theoretical model: deeper network layers contain viewers with higher socioeconomic status and greater financial capacity, despite reduced altruistic motivation due to social distance. Furthermore, exploiting quasi-experimental variations in exposure to China’s Compulsory Schooling Law, we demonstrate that network structure serves as a key mechanism through which fundraisers' education affects crowdfunding success. Our findings reveal how social capital structure systematically shapes inequality in online crowdfunding outcomes, providing broader insights into the distributional consequences of social networks in the digital economy.
