Exploring　complementary　technology　convergence　and　similar　technology　convergence　is　conducive　to　enhancing　enterprise　innovation　capability.　This　paper　analyzes　the　impact　of　partner　diversity　on　technology　convergence　by　building　a　multi-layer　network　model　of　organizational　cooperation　and　technology　convergence.　The　research　shows　that　the　geographic　diversity　of　partners　is　not　conducive　to　the　occurrence　of　complementary　technology　convergence　and　similar　technology　convergence.　The　technological　diversity　of　partners　is　conducive　to　complementary　technology　convergence　but　not　conducive　to　similar　technology　convergence.　The　relationship　strength　between　enterprises　and　different　types　of　partners　has　different　effects　on　complementary　technology　convergence　and　similar　technology　convergence.　The　research　results　can　help　enterprises　choose　appropriate　partners　to　achieve　different　innovation　strategies.　©　2023　Editorial　Borad　of　Complex　Systems　and　Complexity　Science.　All　rights　reserved.
