Abstract：The continuous advancement of value chain division of labor has made urban networks a carrier of industrial innovation and development. The division of labor and collaboration of film enterprises in Beijing has crossed the geographical and spatial boundaries， thus forming the city network based on the industrial ties.Based on 115 films produced by Beijing enterprises in 2015， this paper collects all the cooperative relationship data of 1 307 participating enterprises， and uses social network analysis method to study the city network linkages on which the Beijing film industry relies. It's concluded as follows. 1) The network links show an open spoke pattern， with a high network connectivity of 7.44， an average shortest path of 2.76， and good accessibility. 121 Chinese and foreign urban enterprises participated in the production of films produced in Beijing， providing diversified， open， and abundant capital and information for industrial innovation. 2) Among the network links， Shanghai and Hong Kong have frequent interactions with Beijing in all parts of the value chain. Los Angeles， Seoul and Taipei mainly support Beijing vertically in “post-production” and “distribution”. Shenzhen， Jinhua and Tokyo mainly rely on “co-production” to cooperate with Beijing horizontally. The cross-regional industrial support has become the basis for supporting the innovative development of Beijing film industry. 3) The low threshold of corporate cohesion subgroups in the network， with significant geographic and organizational system proximity， is highly coupled to the internal investment and financing relationship network of China Film Group. However， the less efficient organizational system relationship lock becomes a bottleneck limiting the innovative development of the Beijing film industry.
