An Empirical Assessment of Defensive Innovation to Chinese Import Competition in Japan


This paper empirically examines the defensive innovation hypothesis that firms which have been more exposed to low wage country import competition intensively undertake more innovative activity, using the high quality Japanese firm-level panel dataset over the period 1994-2005.

The novel feature of the analysis is to relate firm-level variations of the patent usage to import competition. The preliminary results suggest that intensified import competition from China has resulted in more innovative activity of Japanese firms, consistent with the finding of European firms in Bloom et al. (2015). Moreover, such competition has also led to both an increase in patents that are used as well as non-used. This finding remains robust to instrumenting Chinese import competitions, the inclusion of other firm-level controls, and measures of import competition from other high and middle income countries.
