Abstract: The phased level of resource endowment of cooperative organizations was directly related to whether cooperatives could standardize development and played an important prerequisite for poverty reduction. On the basis of theoretical analysis, the hypothesis was put forward. Through case empirical analysis of two typical cooperatives in southern Xinjiang, it was found that the organizational resource endowment factors such as scale income, cost saving and efficiency increase, and organizational influence enhancement affected the status of the resource endowment of cooperatives, thus forming the periodical changes of the resource endowment of cooperatives and the normative differences of cooperative organizations composed of internal management and talent resource endowment; the difference in organizational norms caused by the resource endowment of cooperatives was the fundamental reason for the difference in poverty reduction effects of different cooperatives. Based on the conclusion, the effectiveness of cooperatives in poverty reduction was improved through organizational resource endowments of cooperatives such as enriching the scale income, realizing cost-saving and efficiency, and enhancing the organizational influence, as well as the enhancement of the organizational standardization including the internal management of cooperatives and talent resource endowments.
