Abstract: The paper uses the social network analysis method to construct the competitive networks and complementarity networks among 74 major wood forest product economies from 2009 to 2019. From the perspective of network density, node centrality and trade block-models, the paper studies the competitiveness and complementarity among the economies. The results show as follows: first, competitive networks and complementary networks are less closely connected, but complementary networks are closer than competitive networks; thus, there is still a large space for cooperation among the major economies. Second, China is becoming more connected in all trade networks. In the competitive networks, China's node degree ranking is promoted rapidly, and it competes fiercely with other economies. In the complementarity networks, China's node strength increases rapidly, and the trade potential is rather considerable. Third, the trade of wood forest products has formed three competitive groups, the competition between China and other economies has been increasing, and the complementarity relationship within China's plate has gradually weakened from 2009 to 2019. The plate composed of Belarus, Denmark and other economies is an important potential trade partner of China.
