This study aims to demonstrate that the effect of the strength of network ties on performance can vary depending on the nature of the project. Existing network research has presented contradictory claims: one arguing that collecting new information through weak ties is important, and the other arguing that building trust between partners through strong ties is effective for knowledge transfer. However, this study seeks to verify that the effect of network tie strength on performance may differ depending on the degree to which a project requires creativity. In the film industry, the production and export processes carried out at the project team level were classified into two categories: the production process was defined as a project requiring high creativity, while exporting (distributing) the completed film was defined as a project requiring low creativity. To measure the performance generated in these two stages, artistic indicators were used for performance up through the production process, while commercial indicators were employed for export (distribution) performance. For this study, Korean films that were exported overseas or submitted to international film festivals from 2000 to 2006 were selected as the analysis sample. To test the arguments of this paper, the study analyzed how network ties affected the export performance and film festival award performance of the films under analysis. Through empirical analysis, this study demonstrates that in film production networks, stronger ties have a negative effect on a film's artistic performance but a positive effect on its commercial performance.
