Abstract:Using social network analysis method, to build a collaborative innovation network of the BE, quantitative study using UCINET, BE in different time collaborative innovation network evolution graph of network density, distance, and structural hole for analysis. By these structural index of BE collaborative innovation network construction situation was studied. Collaborative innovation networks with different characteristics based on their own development status.With the time extending of collaborative innovation, the network density, network distance, network centrality and network cohesion will be more conducive to the direction of innovation.This provides effective starting point for the improvement of petroleum enterprise collaborative innovation network to promote innovation ability.
