Abstract Based on the representative high-tech industry patent pool MPEG-2, this study collects years of the panel patent-granting data in the members of enterprises in MPEG-2, and builds a multiple hierarchical regression model. The study reveals that the formation of the patent pools has generally curbed the technological innovation of enterprises within the pools. However, it has different influences on enterprises in different network positions in the pools. The results demonstrate that the formation of the patent pools has curbed the technological innovation of the strong enterprises in the pools, but encouraged the technological innovation of the weak enterprises. With the formation of the patent pools, the technology gap between the strong and weak enterprises in the patent pools is shrinking.
