The trend of economic network has been an undisputed fact. Therefore，the global SMEs face a common problem about how to improve their survival ability from economic network environment. This paper first analyzes the importance of social relationship network for SMEs’ survival based on the research at home and abroad. And then from the view point of the relationship number formed from economy and society，the paper analysis comes to a conclusion that there is only a small part of SMEs having plenty of social relationship and this part tends to have a strong survival ability. On the contrary，most of SMEs have a limited number of social relationship，and this part tends to be weak in survival. At last，through a simulation of the relationship between SMEs’ group cooperation behavior and survival ability，this paper proves that group cooperation can improve SMEs’ survival ability.
