Social capital is understood as a resource that is accessed when extensive personal networks are available that actively participate in the different economic and social fields, in an environment of trust and that can facilitate personal and social development, as well as the economic development of a society. Specifically, in the Social Capital Survey, conducted by Eustat, social capital is conceived as a set of dimensions of relationship and participation, among which are: social networks of family and friends, trust in people and institutions, social participation and cooperation, information and communication, cohesion and social inclusion and happiness and health.社会资本（Social Capital）被定义为一种可依托广泛人际网络获取的资源：当个体拥有的社交网络积极参与各类经济与社会领域，且所处环境具备信任氛围时，便可获取该资源，其既能推动个体与社会发展，亦可助力社会的经济发展。 具体而言，由Eustat开展的社会资本调查（Social Capital Survey）将社会资本界定为一组关系与参与维度，具体涵盖：亲友社交网络、对他人与各类机构的信任、社会参与与合作、信息与沟通、社会凝聚力与社会包容，以及幸福感与健康水平。
