After the bilateral trade agreement Closer Economic Partnership Arrangement was signed, coproductions between the film industries in Hong Kong and mainland China have become mainstream. This has led to concerns about the future of Hong Kong’s film and its capability of engaging in international networking. This article applies the international division of cultural labor as a theoretical framework and uses social network analysis to investigate the functions performed by Hong Kong film workers. The article finds that (1) the proportion of Hong Kong film workers is not decreasing, (2) Hong Kong film workers excel at being creative but are losing influence, (3) mainland workers are gaining influence, particularly in administrative coordination, and (4) the producer-centered model is gaining prominence over the director-centered model. Accordingly, the article discusses the structural changes and movement of center occurring in the coproduction network where the coproductions could have little space for transnational expression.
