Using the multivariate ordered logistic and probit regression method, based on the survey data of entrepreneurship concerning farmers in China, we analyze the impact of social capital (namely the social network) on the farmers' recognition of entrepreneurial opportunities and property of entrepreneurial opportunities. The research results show that the scale of farmers being embedded in social network has a positive effect on the probability of farmers to recognize entrepreneurial opportunities. The higher the frequency of contact and the greater the size of weak ties network in the social network, then the greater the possibility of farmers to find innovative opportunities. But strong ties network has no significant effect on replicating-type entrepreneurial opportunities. At the same time, the entrepreneurial farmers’ education experience, migrant worker experience, innovation capability, and deep entrepreneurial atmosphere, are all important factors affecting the farmers' opportunity recognition behavior.
