After a long period of negotiation, exploration, suspension and restart, Geely Group finally acquired 49.9% of the shares of DRB’s Proton Holding and 51% of the shares of the luxury car brand, Lotus Group. On the afternoon of May 24, Geely Holding Group held an acquisition signing ceremony with the Malaysia DRB-HICOM Berhad (hereinafter referred to as DRB). Geely’s commercial territory now extended into Southeast Asia, and its product spectrum increased to luxury sports cars.However, the completion of the acquisition did not mean peace of mind. On the contrary, Geely still faced a series of challenges because of differences in cultural background. The national cultures of the two countries (China and Malaysia) were very different, and so were the values of the two enterprises. Facing the challenges of promoting global human resource integration, Geely needs to make a fundamental decision on the HRM mode in the new-acquired company. Should Geely transplant its own management practice into the Proton, or adopt localized HRM philosophy? Which kind of global HRM practice would be more effective for supporting the new-acquired company developments in the future? In the post-acquisition management, how to better realize the global human resources integration become a key problem faced by Geely.
