From the perspective of OFDI technology-seeking motivation, the paper makes an empirical study with data of China’s OFDI firms. The results show that: (1) OFDI technology-seeking motivation has a significant and positive effect on firm’s productivity, i.e. the higher the level of technological innovation in host country is, the higher the productivity of OFDI firm is;(2) The impacts of OFDI technology-seeking motivation on firm’s productivity are not only heterogeneous, but also different among host countries and regions. Therefore, we believe that seeking higher technology from countries with higher level technological innovation can be an important way to improve productivity; meanwhile it should consider heterogeneity impacts and make classified OFDI implementation.
